| identification of mealybug pest species (hemiptera: pseudococcidae) in egypt and france, using a dna barcoding approach. | pseudococcidae (mealybugs) is a large taxonomic group, including a number of agronomic pests. taxonomic identification of mealybug species is a recurrent problem and represents a major barrier to the establishment of adequate pest management strategies. we combined molecular analysis of three dna markers (28s-d2, cytochrome oxidase i and internal transcribed spacer 2) with morphological examination, for the identification of 176 specimens collected from 40 mealybug populations infesting various ... | 2012 | 22360997 |

| isolation, identification, synthesis, and bioassay of the pheromone of the comstock mealybug and some analogs. | the sex pheromone of the comstock mealybug,pseudococcus comstocki (kuwana) was isolated from volatiles trapped from air passing over virgin female insects. combined gas chromatography, mass and infrared spectroscopy, and microreactions indicated that the structure was 2,6-dimethyl-1,5-heptadien-3-ol acetate. this was confirmed by synthesis; several analogs were also prepared. the natural and synthetic pheromone caused similar trap capture of male insects. synthetic analogs were significantly les ... | 1982 | 24415116 |
| investigating biological control agents for controlling invasive populations of the mealybug pseudococcus comstocki in france. | pseudococcus comstocki (hemiptera: pseudococcidae) is a mealybug species native to eastern asia and present as an invasive pest in northern italy and southern france since the start of the century. it infests apple and pear trees, grapevines and some ornamental trees. biocontrol programmes against this pest proved successful in central asia and north america in the second half of the 20th century. in this study, we investigated possible biocontrol agents against p. comstocki, with the aim of dev ... | 2016 | 27362639 |
| characterization of microsatellite dna libraries from three mealybug species and development of microsatellite markers for pseudococcus viburni (hemiptera: pseudococcidae). | mealybugs (hemiptera: pseudococcidae) are important pests for crops worldwide. different species, cryptic taxa under the same species name or even populations within a species can differ in biological characteristics, such as phenology, resistance to insecticides, virus transmission and susceptibility to natural enemies. therefore, their management efficacy depends on their accurate identification. microsatellite genetic markers are efficient in revealing the fine-scale taxonomic status of insec ... | 2014 | 24345408 |
| temporal dynamics of the arthropod community in pear orchards intercropped with aromatic plants. | background: increasing attention has been paid to enhancing biological control through habitat management in agricultural systems for enhanced pest management. pest management benefits can be realised by intercropping, which can increase natural enemy abundance and, in turn, reduce pest abundance. in this study, the composition and temporal dynamics of arthropod communities in pear orchards when intercropped with aromatic plants were investigated, and the effectiveness and applicability of aroma ... | 2011 | 21480464 |
| identification and characterization of a new vitivirus from grapevine. | new virus-like sequences, tvaq7 and tvp15, were found in a japanese grapevine accession of oky-aq7 (cv. aki queen) and of oky-p15 (cv. pione) by nested rt-pcr to simultaneously amplify a segment of the rna-dependent rna polymerase (rdrp) gene from members of the genera vitivirus and foveavirus. the tvaq7 genome, except for an exact 5' terminus, is composed of about 7.6 kb containing five potential open reading frames. the genomic organization resembles those of grapevine virus a and other known ... | 2008 | 18784974 |
| infection dynamics of coexisting beta- and gammaproteobacteria in the nested endosymbiotic system of mealybugs. | we investigated the infection dynamics of endosymbiotic bacteria in the developmental course of the mealybugs planococcus kraunhiae and pseudococcus comstocki. molecular phylogenetic analyses identified a betaproteobacterium and a gammaproteobacterium from each of the mealybug species. the former bacterium was related to the beta-endosymbionts of other mealybugs, i.e., "candidatus tremblaya princeps," and formed a compact clade in the betaproteobacteria. meanwhile, the latter bacterium was relat ... | 2008 | 18469124 |
| no inbreeding depression in laboratory-reared individuals of the parasitoid wasp allotropa burrelli. | inbreeding depression is a major concern in almost all human activities relating to plant and animal breeding. the biological control of pests with natural enemies is no exception, because populations of biocontrol agents experience a series of bottlenecks during importation, rearing, and introduction. a classical biological control program for the comstock mealybug pseudococcus comstocki (hemiptera: pseudococcidae) was initiated in france in 2008, based on the introduction of an exotic parasito ... | 2017 | 28168032 |
| data on the scale insect (hemiptera: coccomorpha) fauna of greece, with description of two new species. | surveys of the scale insect (hemiptera: coccomorpha) fauna of greece were carried out in 2013 and 2014. altogether 93 scale insect species were collected, belonging to 11 families. thirty-eight species (41%) proved to be new to the greek fauna, including two species new to science (anophococcus hellenicus kaydan & szita sp. n. (acanthococcidae) and iberococcus attikus szita & fetykó sp. n. (pseudococcidae)), and two introduced invasive species (phenacoccus graminicola leonardi and pseudococcus c ... | 2017 | 29242464 |
