Evaluation of Insecticide Toxicity and Enzymatic Detoxification in Neonate Larvae of European Grapevine Moth, Lobesia botrana Denis & Schiff. (Lepidoptera: Tortricidae)

Lobesia botrana Denis & Schiff. (Lepidoptera: Tortricidae), also known as the European grapevine moth is a detrimental pest in grape production Palearctic Region. Insecticides are used to control L. infestation grape-produced areas; however, repeated and intensive use of insecticide causes reduced efficacy management. In present study, five commonly insecticides (chlorpyrifos-ethyl, emamectin benzoate, indoxacarb, lambda-cyhalothrin, spinosad) was evaluated two field populations (AL SAR) from Manisa, Turkey. addition, detoxification enzyme activities including esterase (EST) glutathion-S-transferase (GST) were measured via vitro assays. LC50 values found lower for chlorpyrifos-ethyl, spinosad higher indoxacarb lambda-cyhalotrin AL compared SAR population. EST levels slightly population SAR. GST However, no statistical difference both than populations. Findings current study would help growers well applicator strategize their integrated management programs possibly mitigate any resistance development.
