عنوان انگلیسی Interactions between Entomopathogenic Fungus, Metarhizium anisopliae and Sublethal Doses of Spinosad for Control of House Fly, Musca domestica
چکیده انگلیسی مقاله Background: Metarhizium anisopliae strain IRAN 437C is one of the most virulent fungal isolates against house fly, Musca domestica . The objective of this study was to determine the interaction of this isolate with sublethal doses of spino­sad against housefly. Methods: In adult bioassay, conidia of entomopathogenic fungus were applied as inoculated bait at 10 5 and 10 7 spore per gram and spinosad at 0.5, 1 and 1.5 µg (A.I.) per gram bait. In larval bioassay, conidia were applied as combina­tion of spore with larval bedding at 10 6 and 10 8 spore per gram and spinosad at sublethals of 0.002, 0.004 and 0.006 µg (AI) per gram medium. Results: Adult mortality was 48% and 72% for fungus alone but ranged from 66–87% and 89–95% in combination treat­ments of 10 5 and 10 7 spore/g with sublethal doses of spinosad respectively. The interaction between 10 5 spore/g with sublethals exhibited synergistic effect, but in combination of 10 7 spore in spite of higher mortality, the interac­tion was additive. There was significant difference in LT 50 among various treatments. LT 50 values in all combination treat­ments were smaller than LT 50 values in alone ones. Larval mortality was 36% and 69% for fungus alone but ranged from 58%–78% and 81%–100% in combination treatments of 10 6 and 10 8 spore/g medium with sublethals of spino­sad respectively. The interaction was synergistic in all combination treatments of larvae. Conclusion: The interaction between M. anispliae and spinosad indicated a synergetic effect that increased the house fly mortality as well as reduced the lethal time.
