Cereal monocultures are very susceptible to many pests, especially those living on leaves, which largely affects yield by decreasing its quality. The most dangerous of them is the cereal leaf beetle (Oulema melanopus L.). In cases heavy infestation larvae, surface plants may be reduced 50%, and sometimes even 80%, with a main loss 10–25%. aim presented study was assess efficiency native isolate...
Entomopathogenic nematodes are potent biopesticides that can be mass-produced by in vitro or in vivo methods. For in vivo production, consistently high infection rates are critical to efficiency of the process. Our objective was to optimize in vivo inoculation of Steinernema carpocapsae and Heterorhabditis bacteriophora in Galleria mellonella and Tenebrio molitor by determining effects of inocu...
در سالهای اخیر، کنترل زیستی نماتدهای بیمارگر گیاهی با استفاده از نماتدهای بیمارگر حشرات مورد توجه قرار گرفته است. این تحقیق تاثیر لاروهای آلودهکننده زنده و مرده نماتد بیمارگر حشرات Heterorhabditis bacteriophora Poinar در غلظتهای 5، 10، 25، 50 و 100 لارو در هر میلیلیتر را بهطور جداگانه و در ظرفهای 24 چاهکی روی مرگ ومیر لارو وتفریخ تخم نماتد گره ریشه Meloidogyne javanica Treub در غلظتهای 5...
Biological characteristics of two strains of the entomopathogenic nematode, Heterorhabditis floridensis (332 isolated in Florida and K22 isolated in Georgia) were described. The identity of the nematode's symbiotic bacteria was elucidated and found to be Photorhabdus luminescens subsp. luminescens. Beneficial traits pertinent to biocontrol (environmental tolerance and virulence) were characteri...
