Efficacy of synthetic pyrethroids and quinalphos against Antigastra catalaunalis (Dup.) infesting sesamum

The effectiveness of five synthetic pyrethroids and quinalphos was evaluated against the sesamum leaf webber and capsule borer, Antigastra catalaunalis (Dup.). The insecticides were sprayed thrice at 20-day intervals. Deltamethrin @ 12.5 g, cypermethrin @ 60 g and fenpropathrin @ 100 g a.i./ha were quite effective in reducing flower bud, flower, and pod infestation due to A. catalaunalis in sesamum. Fluvalinate @ 75 g was moderately effective, whereas fenvalerate @ 75 g and quinalphos @ 500 g a.i./ha were less effective insecticides.
