| aflatoxin production by entomopathogenic isolates of aspergillus parasiticus and aspergillus flavus. | fourteen isolates of aspergillus parasiticus and 2 isolates of aspergillus flavus isolated from the mealybug saccharicoccus sacchari were analyzed for production of aflatoxins b1, b2, g1, and g2 in liquid culture over a 20-day period. twelve aspergillus isolates including 11 a. parasiticus and 1 a. flavus produced aflatoxins which were extracted from both the mycelium and culture filtrate. aflatoxin production was detected at day 3 and was detected continually for up to day 20. aflatoxin b1 prod ... | 1990 | 2112577 |
| description of gluconacetobacter sacchari sp. nov., a new species of acetic acid bacterium isolated from the leaf sheath of sugar cane and from the pink sugar-cane mealy bug. | a new species of the genus gluconacetobacter, for which the name gluconacetobacter sacchari sp. nov. is proposed, was isolated from the leaf sheath of sugar cane and from the pink sugar-cane mealy bug, saccharicoccus sacchari, found on sugar cane growing in queensland and northern new south wales, australia. the nearest phylogenetic relatives in the alpha-subclass of the proteobacteria are gluconacetobacter liquefaciens and gluconacetobacter diazotrophicus, which have 98.8-99.3% and 97.9-98.5% 1 ... | 1999 | 10555349 |
| molecular detection of gluconacetobacter sacchari associated with the pink sugarcane mealybug saccharicoccus sacchari (cockerell) and the sugarcane leaf sheath microenvironment by fish and pcr. | molecular tools for the detection of the newly described acetic acid bacterium gluconacetobacter sacchari from the pink sugarcane mealybug, saccharicoccus sacchari cockerell (homiptera: pseudococcidae), and in the sugarcane leaf sheath microenvironment were developed. g. sacchari specific 16s rrna-targeted oligonucleotide primers were designed and used in pcr amplification of g. sacchari dna directly from mealybugs, and in a nested pcr to detect low numbers of the bacteria from sugarcane leaf sh ... | 2000 | 10620720 |
| design, development, and use of molecular primers and probes for the detection of gluconacetobacter species in the pink sugarcane mealybug. | molecular tools for the species-specific detection of gluconacetobacter sacchari, gluconacetobacter diazotrophicus, and gluconacetobacter liquefaciens from the pink sugarcane mealybug (psmb) saccharicoccus sacchari cockerell (homiptera: pseudococcidae) were developed and used in polymerase chain reactions (pcr) and in fluorescence in situ hybridizations (fish) to better understand the microbial diversity and the numerical significance of the acetic acid bacteria in the psmb microenvironment. the ... | 2005 | 16047097 |
| acetic acid bacteria, newly emerging symbionts of insects. | recent research in microbe-insect symbiosis has shown that acetic acid bacteria (aab) establish symbiotic relationships with several insects of the orders diptera, hymenoptera, hemiptera, and homoptera, all relying on sugar-based diets, such as nectars, fruit sugars, or phloem sap. to date, the fruit flies drosophila melanogaster and bactrocera oleae, mosquitoes of the genera anopheles and aedes, the honey bee apis mellifera, the leafhopper scaphoideus titanus, and the mealybug saccharicoccus sa ... | 2010 | 20851977 |
| scale insects (hemiptera: coccomorpha) on sugarcane in colombia, with description of a new species of tillancoccus ben-dov (coccidae). | herein we describe a new species, tillancoccus koreguajae caballero & ramos, sp. n. (hemiptera: coccidae) from colombia collected on sugarcane. pinnaspis strachani (cooley) is also recorded on sugarcane for the first time worldwide. an updated list of seven species of coccomorpha on sugarcane in colombia is provided, including information on its distribution, biology, and mutualistic ants for each species. seven species of scale insects (hemiptera: coccomorpha) have been recorded previously on s ... | 2017 | 28609908 |
| 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 |
