- Abstract
Legume pod borer, Maruca vitrata F. is the most devastating insect pest of food legumes worldwide. The larvae cause damage to flowers, flower buds, pods and developing grains. In the absence of any viable biocontrol agents and resistant plant varieties, various groups of insecticides with different mode of action are routinely used to protect the crop. Hence, the study was undertaken to evaluate the relative toxicity of the commonly used insecticides viz., indoxacarb 14.5 SC, chlorpyriphos 20 EC, spinosad 45 SC, emamectin benzoate 5 SG and lambda cyhalothrin 5 EC against second and third instar larvae of M. vitrata under laboratory conditions. The results revealed that emamectin benzoate 5 SG was the most toxic followed by indoxacarb 14.5 SC, spinosad 45 SC and lambda cyhalothrin 5 EC and chlorpyriphos 20 EC. The knowledge can help in integration of effective insecticides in IPM systems for the management of the pod borer.
