Insecticidal Activity of against .

causes considerable economic damage to small and thin-skinned fruits including cherry, blueberry, raspberry, grape and strawberry. Since it attacks fruits at the ripening stage, the use of chemical pesticides is limited due to the high risk of residues on fruit. Biological control is thus expected to play an essential role in managing this pest. The Gram-negative bacterium, and its symbiotic spp. nematode have been shown to be highly pathogenic to insects, with a potential for replacing pesticides to suppress several pests. Insecticidal activity of at different bacterial cell concentrations and its cell-free supernatant were assessed against third-instar larvae and pupae of under laboratory conditions. suspensions had a significant oral and contact toxicity on larvae and pupae, with mortalities up to of 70⁻100% 10 days after treatment. Cell-free supernatant in the diet also doubled mortality rates of feeding larvae. Our results suggest that may be a promising candidate for biological control of , and its use in integrated pest management (IPM) programs is discussed.
