Evaluation of different insecticides against mango midges (Diptera: Cecidomyiidae)

Abstract

The present study was conducted to evaluate insecticides for the control of mango midges under field conditions. Four insecticides: Bifenthrin (100 g/L EC), Nitenpyram (100 g/L SL), Emamectin Benzoate (14.2 g/L EC) and Imidacloprid (200 g/L SL) were evaluated for it efficacy to reduce the larval population and the development of new galls. The results showed that the maximum reduction in the larval population was recorded in Nitenpyram insecticide showed (87.97%) mortality and the minimum larval mortality was recorded in Emamectin benzoate with (71.31%). The infestation of midges continues after treatment but the Bifenthrin treated trees showed least development of galls from 0.27±0.81 to 1.16±0.27% and the maximum development of gall recorded in Imidacloprid and Nitenpyram treated trees which showed same development of galls in all seven weeks. These findings can be helpful in effective management of mango gall midges.
