| acaricomes phytoseiuli gen. nov., sp. nov., isolated from the predatory mite phytoseiulus persimilis. | a gram-positive, rod-shaped, non-spore-forming bacterium, strain csct, was isolated from diseased, surface-sterilized specimens of the predatory mite phytoseiulus persimilis athias-henriot and subjected to polyphasic taxonomic analysis. comparative analysis of the 16s rrna gene sequence revealed that the strain was a new member of the family micrococcaceae. nearest phylogenetic neighbours were determined as renibacterium salmoninarum (94.0%), arthrobacter globiformis (94.8%) and arthrobacter rus ... | 2006 | 16449459 |
| novel bacterial pathogen acaricomes phytoseiuli causes severe disease symptoms and histopathological changes in the predatory mite phytoseiulus persimilis (acari, phytoseiidae). | adult female phytoseiulus persimilis athias-henriot (acari, phytoseiidae) of a laboratory population show a set of characteristic symptoms, designated as non-responding (nr) syndrome. mature predators shrink, cease oviposition and die. they show a lower degree of attraction to herbivore-induced plant volatiles and a greater tendency to leave prey patches carrying ample prey. moreover, predators may carry excretory crystals in the legs, may cease prey consumption and have a low excretion rate. he ... | 2008 | 18423485 |
| natural enemies of mass-reared predatory mites (family phytoseiidae) used for biological pest control. | predatory mites of the family phytoseiidae are valued natural enemies that provide effective pest control in greenhouses and on agricultural crops. mass-reared phytoseiids are occasionally associated with microorganisms and although their effects are not always apparent, some are pathogenic and reduce host fitness. invertebrate pathogens are encountered more frequently in mass production systems than in nature because rearing environments often cause overcrowding and other stresses that favour p ... | 2008 | 18726699 |
| verified and potential pathogens of predatory mites (acari: phytoseiidae). | several species of phytoseiid mites (acari: phytoseiidae), including species of the genera amblyseius, galendromus, metaseiulus, neoseiulus, phytoseiulus and typhlodromus, are currently reared for biological control of various crop pests and/or as model organisms for the study of predator-prey interactions. pathogen-free phytoseiid mites are important to obtain high efficacy in biological pest control and to get reliable data in mite research, as pathogens may affect the performance of their hos ... | 2008 | 18763041 |
