Capnodis tenebrionis L.'den izole edilen bakterilerin izolasyonu, karakterizasyonu ve bazı böcek zararlılarına karşı biyolojik mücadele potansiyelleri

Abstract

Capnodis tenebrionis L. (Coleoptera: Buprestidae) is one of the most destructive pests of stone fruit orchards in several countries, including Türkiye. In the present study, 21 bacterial isolates were isolated from the larvae and adults of C. tenebrionis. The morphological, physiological, biochemical and molecular characteristics of the bacterial isolates were determined. The bacterial flora isolated from C. tenebrionis was as follows: Bacillus cereus, B. mycoides, B. pumilus, Paenibacillus xylanilyticus, B. flexus, B. simplex, Raoultella terrigena, Enterobacter cloacae, Klebsiella oxytoca, B. safensis, B. amyloliquefaciens and B. aryabhattai. The biological control potential of these bacterial isolates against the larvae of several economic pest species, the elm leaf beetle (Pyrrhalta luteola (M.)), the honeycomb moth (Galleria mellonella L.), and the mealworm (Tenebrio molitor Ludwig), was investigated. The isolates of B. cereus showed the highest efficacy against these insect pests.
