Integrated methods in pest control : effect of insecticides on entomopathogenic fungi (Beauveria bassiana (Bals) Vuill., B. brongniartii (Sacc.)) and nematodes (Heterorhabditis megidis Poinar, Jackson, Klein, Steinernema feltiae Filipjev, S. glaseri Steiner)

Sensitivity of two species of entomopathogenic fungi: Beauveria bassinana and B. brongniartii and of three species of entomopathogenic nematodes: Steinernema glaseri, S. feltiae and Heterorhabditis megidis to low doses of two insecticides carbosulfan and carbofuran applied to forest soil to control cockchafer's grubs was studied. Carbosulfan inhibited the growth of both fungi. Carbofuran stimulated the growth of B. brongniartii. Mortiality of carbofuran treated nematodes was higher than mortality of those affected by carbosulfan. Both insecticides did not decrease the pathogenicity of fungi and nematodes towards Galleria mellonella L. larvae. The studies pointed to a possibility of using both insecticides in the Integrated Pest Management.
