PATHOGENICITY OF FIVE STRAINS OF ENTOMOGENOUSFUNGITOAEDES ALBOPICTUSLARVAEANDADULTS
摘要
Abstract
With the occurrence of drug resistance to traditional chemical insecticides in mosquitoes , a great attention has been paid to the development of bio-insecticides.The 5 entomogenous fungi strains, including 4 strains of Beauveria bassiana and one strain of Metarhizium anisopliae, that are frequently used in biological control of insects , were used in killing Aedes albopictus mosquitoes.Different concentrations of fungal spore suspension were used in the detection of toxicity to larvae, and the same amount of spores on the solid culture medium were used in the detection of toxicity to adults .The toxicity of the entomogenous fungi strains was evaluated with the cumulative adjusted mortality of Ae.albopictus larvae or adults treated with entomogenous fungi spores for 10 days.The results showed that the 5 entomogenous fungi strains, GM3.428, GIM3.45, GIM3.528, GIM3.436 and GIM3.46, resulted in a cumulative adjusted mortality of ( 46.7 ± 2.3)%, (45.0 ±4.0)%, (41.7 ±2.3)%, (35.0 ±4.0)% and (25.0 ±4.0)% respectively, to mosquito larvae, and a cumulative adjusted mortality of (37.8 ±3.1)%, (51.1 ±4.1)%, (38.9 ±4.1)%, (30.0 ±2.7)% and (17.8 ± 3.1)% to mosquito adults, respectively.GIM3.45 and GIM3.428 strain of B.bassiana are the most toxic to Ae.albopictus larvae and adults, showing the best effects in killing Ae.albopictus mosquitoes.The most toxic strains against Ae.albopictus were selected based on the present study, which provides a scientific basis for the bio-insecticide development for mosquito control.关键词
