abstract
The oriental fruit fly, Bactrocera dorsalis (Hendel), is a devastating insect pest that causes large losses and acts as an export barrier for many fruits and vegetables globally. This study evaluated the toxicity of Imidacloprid 25% Wp (Advance Agro^®), Trichlorfon 80% SP (Avari^®) and Emamectin benzoate 1.9% EC (Welcon^®) applied as bait against adults of B. dorsalis under laboratory conditions (26.0 ± 2.0 °C and 70.0 ± 5.0% R.H.). Experiment was conducted under Completely Randomized Design (CRD) with factorial arrangements through which mass reared adults of B. dorsalis were treated with three concentrations (2, 4 and 8 ppm) of each insecticide along with a control treatment having no insecticide. Mortality percentage of these flies was recorded after 24 and 48 h post treatment. Results revealed that Trichlorfon showed highest mortality (100%) followed by Emamectin benzoate (70%) and Imidacloprid (69.44%) respectively.
