| sex pheromone of the vine mealybug, planococcus ficus in israel: occurrence of a second component in a mass-reared population. | two pheromonal components were detected in airborne collections from the vine mealybug planococcus ficus (signoret) (hemiptera: pseudococcidae) mass-reared on potato sprouts. the compounds were identified as (s)-lavandulyl senecioate (i) and (s)-lavandulyl isovalerate (ii) by gc and gc-ms by comparison with synthetic standards. chiral gc analysis on a cyclodextrin column established their chirality. compound i was identified recently as the sex pheromone of p. ficus in california. the attraction ... | 2003 | 12775156 |
| natural enemies of three mealybug species (hemiptera: pseudococcidae) found on citrus and effects of some insecticides on the mealybug parasitoid coccidoxenoides peregrinus (hymenoptera: encyrtidae) in south africa. | the population density of mealybug species in some south african citrus orchards has increased to pest status in recent years. the characterization of the natural enemy complex and quantification of their contribution to the control of planococcus citri (risso), pseudococcus longispinus (targioni-tozzetti) and pseudococcus calceolariae (maskell) on citrus limon (l.) and citrus reticulata (blanco) was investigated through intensive sampling. eight primary and four secondary parasitoids, and two p ... | 2003 | 12762866 |
| pathogenic effects of bacteria isolated from larvae of hylesia metabus crammer (lepidoptera: saturniidae). | hylesia metabus larvae are susceptible to several pathogens indigenous to the area in which they are found. some larvae show symptoms characteristic of bacterial infection; they become flaccid and lethargic, and show a marked loss of appetite. we isolated and identified 29 bacterial strains from live, dead and experimentally infected h. metabus larvae, and evaluated their pathogenic activity. the bacteria which caused mortality in the larvae were: pseudomonas aeruginosa (60-93.3%), proteus vulga ... | 2002 | 12234536 |
| development and optimization of methods for using sex pheromone for monitoring the mealybug planococcus ficus (homoptera: pseudococcidae) in california vineyards. | the sex pheromone of the vine mealybug planococcus ficus signoret has been identified as a single component, lavandulyl senecioate. racemic lavandulyl senecioate was as attractive to male mealybugs as the insect-produced (s)-enantiomer, indicating that the unnatural enantiomer is not inhibitory. lavandulol, which also was found in extracts from virgin females, antagonized attraction of males at higher doses. rubber septum lures loaded with 10- to 1,000-microg doses of the pheromone were equally ... | 2002 | 12216810 |
| a novel antimicrobial function for a ribosomal peptide from rainbow trout skin. | an antimicrobial peptide was purified from skin secretions and epithelial cells of rainbow trout by cation exchange and reversed phase chromatography. partial n-terminal amino acid sequence of the purified peptide revealed 100% identity with the first 11 residues of a 40s ribosomal peptide from medaka fish. its molecular mass, determined by matrix-associated laser desorption/ionisation mass spectrometry, was found to be 6676.6da. these results indicate that this antimicrobial peptide is likely t ... | 2002 | 12147245 |
| characterization of the genome of the mealybug planococcus lilacinus, a model organism for studying whole-chromosome imprinting and inactivation. | the co-occurrence of three chromosome-wide phenomena--imprinting, facultative heterochromatization and diffuse centromere--in the mealybug planococcus lilacinus makes investigation of the genomics of this species an attractive prospect. in order to estimate the complexity of the genome of this species, 300 random stretches of its dna, constituting approximately 0.1% of the genome, were sequenced. coding sequences appear to constitute approximately 53.5%, repeat sequences approximately 44.5% and ... | 2002 | 12073549 |
| planococcus antarcticus and planococcus psychrophilus spp. nov. isolated from cyanobacterial mat samples collected from ponds in antarctica. | thirteen orange-pigmented bacteria associated with cyanobacterial mat samples collected from four different lakes in mcmurdo, antarctica, were isolated. twelve of the isolates, which were coccoid in shape, were very similar and possessed all the characteristics of the genus planococcus and represented a new species, which was assigned the name planococcus antarcticus sp. nov. (cms 26or(t)). apart from the phenotypic differences, p. antarcticus differed from all reported species of planococcus by ... | 2002 | 12072961 |
| genetic characterization of a putative densovirus from the mealybug planococcus citri. | total genomic dna preparations from the citrus mealybug, planococcus citri, contained a dna band corresponding to 5.5 kilobases. this dna was a linear molecule and was cloned into puc18. nucleotide sequence determination indicated that it was the replicative form of a densovirus, most closely related to the virus from periplaneta fuliginosa (smokybrown cockroach). | 2001 | 11685517 |
| facultative heterochromatization in parahaploid male mealybugs: involvement of a heterochromatin-associated protein. | the behavior of chromosomes during development of the mealybug planococcus citri provides one of the most dramatic examples of facultative heterochromatization. in male embryos, the entire haploid paternal chromosome set becomes heterochromatic at mid-cleavage. male mealybugs are thus functionally haploid, owing to heterochromatization (parahaploidy). to understand the mechanisms underlying facultative heterochromatization in male mealybugs, we have investigated the possible involvement of an hp ... | 2001 | 11585806 |
| characterization of a halotolerant-psychroloterant bacterium from dry valley antarctic soil. | the saline soils of the ice free dry valleys of victoria land, antarctica may provide the closest analog on earth to martian conditions. we have initiated a study aimed at examining microbial adaptations to the harsh environment of these dry valley soils. in this report we describe the characterization of one bacterium, strain a4a, isolated from taylor valley soil. strain a4a was an obligately aerobic, orange-pigmented, gram-positive coccus that grew over wide ranges of both temperature (0 degre ... | 1983 | 11542754 |

| influence of egg load and oviposition time interval on the host discrimination and offspring survival of anagyrus pseudococci (hymenoptera: encyrtidae), a solitary endoparasitoid of citrus mealybug, ++planococcus citri (hemiptera: pseudococcidae). | oviposition and host discrimination behaviour of unmated anagyrus pseudococci (girault), an endoparasitoid of the citrus mealybug planococcus citri (risso), were investigated in the laboratory. female parasitoids were able to discriminate between parasitized hosts and healthy ones. the mean number of ovipositions was significantly higher in unparasitized than in parasitized hosts. conspecific-superparasitism occurred more often than self-superparasitism. changes in consecutive ovipositions over ... | 2000 | 10948366 |
| hot water treatment and insecticidal coatings for disinfesting limes of mealybugs (homoptera: pseudococcidae). | hot water immersion and insecticidal coatings were tested to determine if they could be used to disinfest persian limes, citrus latifolia tanaka, of the mealybug pests planococcus citri risso and pseudococcus odermatti miller & williams. a 20-min 49 degrees c hot water immersion treatment is effective in killing mealybugs and all other arthropods tested found externally on limes, or under the calyx. no insects or mites were found to survive after the 20-min hot water treatment. in this test, 7,2 ... | 2000 | 10902365 |
| [the use of batumin-containing disks for the rapid identification of staphylococci]. | the study of 467 microbial strains obtained from collections and from clinical sources revealed that microorganisms of the genus staphylococcus were highly sensitive to batumin, a new antibiotic obtained from bacteria of the genus pseudomonas. 378 strains of 15 staphylococcus species proved to be highly sensitive to the diagnostic preparation "diastaph", developed on the basis of batumin (antibiotic-impregnated discs); after 18-hour incubation the diameter of the growth inhibition zones on agar- ... | 1999 | 10852028 |
| characterization of a salt-tolerant family 42 beta-galactosidase from a psychrophilic antarctic planococcus isolate. | we isolated a gram-positive, halotolerant psychrophile from a hypersaline pond located on the mcmurdo ice shelf in antarctica. a phylogenetic analysis of the 16s rrna gene sequence of this organism showed that it is a member of the genus planococcus. this assignment is consistent with the morphology and physiological characteristics of the organism. a gene encoding a beta-galactosidase in this isolate was cloned in an escherichia coli host. sequence analysis of this gene placed it in glycosidase ... | 2000 | 10831422 |
| sex-specific organisation of middle repetitive dna sequences in the mealybug planococcus lilacinus. | differential organisation of homologous chromosomes is related to both sex determination and genomic imprinting in coccid insects, the mealybugs. we report here the identification of two middle repetitive sequences that are differentially organised between the two sexes and also within the same diploid nucleus. these two sequences form a part of the male-specific nuclease-resistant chromatin (nrc) fraction of a mealybug planococcus lilacinus. to understand the phenomenon of differential organisa ... | 1999 | 10471745 |
| cytosine methylation is not involved in the heterochromatization of the paternal genome of mealybug planococcus citri. | 1999 | 10219735 | |
| the relationship between dna methylation and chromosome imprinting in the coccid planococcus citri. | the phenomenon of chromosome, or genomic, imprinting indicates the relevance of parental origin in determining functional differences between alleles, homologous chromosomes, or haploid sets. in mealybug males (homoptera, coccoidea), the haploid set of paternal origin undergoes heterochromatization at midcleavage and remains so in most of the tissues. this different behavior of the two haploid sets, which depends on their parental origin, represents one of the most striking examples of chromosom ... | 1999 | 10101170 |
| the enzymatic activity of phosphoglycerate mutase from gram-positive endospore-forming bacteria requires mn2+ and is ph sensitive. | the enzymatic activity of phosphoglycerate mutase (pgm) from three gram-positive endospore-forming bacteria (bacillus subtilis, clostridium perfringens, and sporosarcina ureae) requires mn2+ and is very sensitive to ph; at low concentrations of mn2+, a ph change from 8 to 6 resulted in greater than 30- to 200-fold decreases in the activity of these pgms. however, pgm deactivation at ph 6 was reversed by shifting the enzyme to ph 7 or 8. free mn2+ was not directly involved in pgm catalysis, altho ... | 1998 | 9830105 |
| arthrobacter, brachybacterium and planococcus isolates identified from antarctic sea ice brine. description of planococcus mcmeekinii, sp. nov. | three facultative psychrophilic gram-positive bacterial strains were isolated from brine samples from the sea ice community in antarctica. all strains were coccoid to rod-shaped and exhibited broad salinity and temperature ranges for growth. the three strains were subjected to 16s rdna sequencing and subsequent phylogenetic analysis. all possess unique 16s rdna sequences indicating they are new, previously unreported organisms. phylogenetic analyses coupled with phenotypic characterization indic ... | 1998 | 9704115 |
| styelins, broad-spectrum antimicrobial peptides from the solitary tunicate, styela clava. | two novel phenylalanine-rich antimicrobial peptides, styelin a and styelin b, were purified from the hemocytes of styela clava. the peptides had very similar masses (styelin a, 3685.8; styelin b, 3700.6) and amino acid compositions, and at least 17 of their first 20 n-terminal residues were identical. both styelins were effective against a panel of gram negative and gram positive bacterial pathogens of humans, usually acting with minimal inhibitory concentrations < 1.5 microgram/ml (< 0.5 microm ... | 1997 | 9467865 |
| [sensitization and allergic pathology in a group of workers employed in insect breeding for biological pest control]. | on the basis of the results of a previous study and immuno-allergological tests, a group of workers employed in breeding insects for biological pest control were studied to ascertain whether any new sensitizations to arthropods recently included in the work cycle occurred and whether any new allergic diseases were observed. the results confirmed a high sensitization to ephestia kuehniella and to orius, the latter probably due to contamination; sensitization to tetranicus urticae and to planococc ... | 1997 | 9379990 |
| identification and nh2-terminal amino acid sequences of dnak and groel homologues in moderate eubacterial halophiles. | we have identified 2 dnak and 3 groel homologues from moderately halophilic acinetobacter, pseudomonas, and planococcus species by partial purification using an atp-agarose column and by the analysis and similarity search of these nh2-terminal amino acid sequences. although these bacteria required 1 to 2m nacl for growth, these dnak and groel homologues did not require high salt to bind to the atp column, thus suggesting that these chaperones did not require high salts for their biochemically ac ... | 1997 | 9301123 |
| coffea arabica l., a new host plant for acetobacter diazotrophicus, and isolation of other nitrogen-fixing acetobacteria. | acetobacter diazotrophicus was isolated from coffee plant tissues and from rhizosphere soils. isolation frequencies ranged from 15 to 40% and were dependent on soil ph. attempts to isolate this bacterial species from coffee fruit, from inside vesicular-arbuscular mycorrhizal fungi spores, or from mealybugs (planococcus citri) associated with coffee plants were not successful. other acid-producing diazotrophic bacteria were recovered with frequencies of 20% from the coffee rhizosphere. these n2-f ... | 1997 | 9293018 |
| diversity and association of psychrophilic bacteria in antarctic sea ice. | the bacterial populations associated with sea ice sampled from antarctic coastal areas were investigated by use of a phenotypic approach and a phylogenetic approach based on genes encoding 16s rrna (16s rdna). the diversity of bacteria associated with sea ice was also compared with the bacterial diversity of seawater underlying sea ice. psychrophilic (optimal growth temperature, < or = 15 degrees c; no growth occurring at 20 degrees c) bacterial diversity was found to be significantly enriched i ... | 1997 | 9251193 |
| developmental analysis of a female-specific 16s rrna gene from mycetome-associated endosymbionts of a mealybug, planococcus lilacinus. | a clone showing female-specific expression was identified from an embryonic cdna library of a mealybug, planococcus lilacinus. in southern blots this clone (p7) showed hybridization to genomic dna of females, but not to that of males. however, p7 showed no hybridization to nuclei of either sex, raising the possibility that it was extrachromosomal in origin. in sectioned adult females p7 hybridized to an abdominal organ called the mycetome. the mycetome is formed by mycetocytes, which are polyplo ... | 1996 | 9035384 |
| emendation of the genus planococcus and transfer of flavobacterium okeanokoites zobell and upham 1944 to the genus planococcus as planococcus okeanokoites comb. nov. | the taxonomic position of flavobacterium okeanokoites ifo 12536t (t = type strain) was determined by 16s rrna gene sequencing and chemotaxonomic methods. phylogenetic evidence derived from a 16s rrna sequence analysis indicated that f. okeanokoites, which forms rod-shaped cells, belongs to the genus planococcus, which forms spherical cells. a phylogenetically close relationship was supported by chemotaxonomic characteristics, such as the presence of menaquinone 7 and menaquinone 8 as major isopr ... | 1996 | 8863410 |
| a male-specific nuclease-resistant chromatin fraction in the mealybug planococcus lilacinus. | in mealybugs, chromatin condensation is related to both genomic imprinting and sex determination. the paternal chromosomal complement is condensed and genetically inactive in sons but not in daughters. during a study of chromatin organization in planococcus lilacinus, digestion with micrococcal nuclease showed that 3% to 5% of the male genome is resistant to the enzyme. this nuclease resistant chromatin (nrc) apparently has a nucleosomal organization. southern hybridization of genomic dna sugges ... | 1996 | 8575251 |
| phylogenetic interrelationships of round-spore-forming bacilli containing cell walls based on lysine and the non-spore-forming genera caryophanon, exiguobacterium, kurthia, and planococcus. | the 16s rrna gene sequences of "bacillus aminovorans" and several species considered to be phylogenetically related to the group 2 bacilli of ash et al. (c. ash, j. a. e. farrow, s. wallbanks, and m. d. collins, lett. appl. microbiol. 13:202-206, 1991) were determined. a comparative analysis of the sequence data revealed that the round-spore-forming group 2 bacilli, together with some asporogenous taxa (the genera caryophanon, exiguobacterium, kurthia, planococcus), form a phylogenetically disti ... | 1994 | 8123563 |
| comparison of antibacterial activity in the hemocytes of different crustacean species. | antibacterial activity in hemocytes of the squat lobster, galathea strigosa, the norway lobster, nephrops norvegicus, the common shrimp, crangon crangon, and the giant antarctic isopod, glyptonotus antarcticus, was investigated in vitro. for all species, the marine bacterium, psychrobacter immobilis, was used as the test organism, although with g. antarcticus, the gram positive bacteria, planococcus citreus and bs 68 (an isolate from antarctic waters), were also used. hemocyte lysate supernatant ... | 1995 | 7866773 |

| variation in pigment production by planococcus citreus migula with cultural age and with sea salt concentration in the medium. | the biosynthesis of carotenoids and the type of carotenoids produced by planococcus citreus migula appear to be influenced by the concentration of sea salt in the medium and by the age of culture. quantitatively, pigmentation peaks at a time corresponding to the presence of maximum cell numbers and then undergoes a rapid decline. | 1980 | 7396481 |
| numerical taxonomy of staphylococci. | over two hundred staphylococci from human and animal sources and representatives of established species of staphylococcus, micrococcus and planococcus were compared in a numerical phenetic survey using 115 unit characters. data were analyzed using the jaccard coefficient and the unweighted pair group method with averages algorithm. cluster composition was not markedly affected by test error, estimated as 3.49%. the staphylococci were assigned to eighteen clusters containing four or more strains ... | 1983 | 6659744 |
| correlation between phosphorylated h1 histone and condensed chromatin in planococcus citri. | histones of the mealybug planococcus citri have been isolated and characterised. although no major differences were observed between the core histones of male and female insects, the pattern of h1 histones was significantly different between the sexes. a specific hyperphosphorylated h1 was found to be present only in male mealybugs, where the paternal chromosomes are condensed and transcriptionally inactive. | 1983 | 6628682 |

| effects of temperature and sodium chloride concentration on the phospholipid and fatty acid compositions of a halotolerant planococcus sp. | the phospholipid headgroup composition and fatty acid composition of a gram-positive halotolerant planococcus sp. (strain a4a) were examined as a function of growth temperature (5 to 35 degrees c) and nacl content (0 to 1.5 m) of the growth medium. when the growth temperature was decreased, the relative amount of mono-unsaturated branched-chain fatty acids increased. when planococcus sp. strain a4a was grown in media containing high nacl concentrations, the relative amount of the major fatty aci ... | 1985 | 3980436 |
| effects of monovalent and divalent salts on the phospholipid and fatty acid compositions of a halotolerant planococcus sp. | the phospholipid headgroup and fatty acid compositions of a halotolerant planococcus sp. (strain a4a) were examined when cells were grown in the presence of high concentrations of a variety of salts. the fatty acid composition of planococcus sp. strain a4a was altered primarily as a function of the osmolality of the growth medium. the phospholipid headgroup composition was influenced by both the osmolality of the growth medium and the nature of the cation species present. an increase in the card ... | 1986 | 3801094 |
| distribution and types of bacteria isolated from an inland saltern. | the physico-chemical characteristics and bacterial populations of an inland saltern were studied. the well water leading into the ponds of the saltern differed from sea water in its total salinity (18% (w/v)) and had lower mg2+ and so4(2-) contents and much higher contents of cl-, ca2+- and k+. a high proportion of halotolerant microorganisms were isolated, although marine bacteria were not found. most of the halophilic strains isolated appeared to be typical moderate halophiles, and included si ... | 1987 | 3606874 |
| rapid lysostaphin test to differentiate staphylococcus and micrococcus species. | a rapid, simple lysostaphin lysis susceptibility test to differentiate the genera staphylococcus and micrococcus was evaluated. of 181 strains from culture collections, 95 of 95 staphylococcus strains were lysed, and 79 of 79 micrococcus strains were not lysed. the seven planococcus strains were resistant. clinical isolates (890) were tested with lysostaphin and for the ability to produce acid from glycerol in the presence of erythromycin. overall agreement between the methods was 99.2%. all cli ... | 1986 | 3519667 |

| role of various microorganisms on tc behavior in sediments. | marine bacteria (moraxella sp., planococcus sp. and a mixed population of anaerobes) from a coastal sediment were found to concentrate tc. maximum concentration of this element occurred during the stationary phase of growth of the bacteria, at low redox potential. a metabolic process seems responsible for tc concentration by bacteria, in which it binds to high molecular weight cellular constituents. polysaccharidic polymers, which were visualized around the bacterial cells with the scanning elec ... | 1989 | 2592213 |
| comparative 16s rrna oligonucleotide analyses and murein types of round-spore-forming bacilli and non-spore-forming relatives. | the phylogenetic incoherency of the genus bacillus as presently described is demonstrated by analysis of both published and new data from comparative 16s rrna cataloguing of nine bacillus species and a number of related non-bacillus taxa, i.e. caryophanon latum, filibacter limicola and planococcus citreus. while the ellipsoidal-spore-forming bacilli, e.g. b. subtilis and allied species, formed a coherent cluster, the round-spore-forming bacilli showed a higher degree of relationship to the non-s ... | 1987 | 2452227 |
| 16s ribosomal rna analysis of filibacter limicola indicates a close relationship to the genus bacillus. | the phylogenetic relationship of the gram-negative, filamentous gliding bacterium filibacter limicola was analysed by 16s rrna oligonucleotide cataloguing. in contrast to the proposed membership of this asporogenous species in the flexibacteriaceae, filibacter limicola clusters phylogenetically with the gram-positive eubacteria bacillus pasteurii, sporosarcina ureae and the asporogenous species planococcus citreus. the genetic relationship is supported by several common phenotypic properties. | 1985 | 2415672 |
| cloning and expression of drosophila hp1 homologs from a mealybug, planococcus citri. | the mealybug chromosome cycle is one of the most dramatic examples of genomic imprinting known. in embryos that are to become male the entire paternal chromosome set becomes heterochromatic and inactive at the blastoderm stage, while the maternal set remains active and euchromatic. hp1 is a protein from drosophila melanogaster, which binds preferentially to heterochromatin on polytene chromosomes and is likely to be a modifier of position effect variegation. this paper describes the isolation an ... | 1992 | 1629256 |
| phylogenetic analysis of the genera planococcus, marinococcus and sporosarcina and their relationships to members of the genus bacillus. | a phylogenetic analysis based on 16s rrna was performed on the genera planococcus, marinococcus, sporosarcina and endospore-forming rods. in agreement with earlier 16s rrna cataloguing data, planococcus citreus and sporosarcina ureae clustered with bacillus pasteurii and other bacilli containing lysine in their cell walls. sporosarcina halophila was shown to be genetically distinct from s. ureae and formed a loose association with the main bacillus subtilis grouping. marinococcus halophilus (for ... | 1992 | 1505740 |
| detection of a cpa methylase in an insect system: characterization and substrate specificity. | a cytosine-specific dna methyltransferase (ec 2.1.1.37) has been purified to near homogeneity from a mealybug (planococcus lilacinus). the enzyme can methylate cytosine residues in cpg sequences as well as cpa sequences. the apparent molecular weight of the enzyme was estimated as 135,000 daltons by fplc. the enzyme exhibits a processive mode of action and a salt dependence similar to mammalian methylases. mealybug methylase exhibits a preference for denatured dna substrates. | 1992 | 1374836 |
