Biological control of the small leafhopper, Empoasca flavescens F. (Homoptera: Cicadellidae) using the entomopathogenic fungus, Verticillium lecanii

Abstract Background Nowadays, instead of chemicals, using microbial pesticides is very important and significant to protect the environment. Verticillium lecanii (Z), entomopathogenic fungus, widely used for management many pests. The aim this work determine whether small leafhopper, Empoasca flavescens F. (Homoptera: Cicadellidae), can be exterminated only by biopesticide— V. or not. Results After spraying with diluted suspension spores on E. , effects infection reinfection in accordance time, spore density growth stage leafhoppers were studied. When E . was sprayed over 1.25 × 10 8 spores/ml fungal indoors, reduction % 80% after 5 days decrease imagoes higher than that larvae. Outdoors, reduced 50% 3 years treatment, while about 90% year year. Conclusion Ninety percentages peach trees effectively 2 spore, no chemical are needed control practice.
