abstract

The present study was conducted to findout the prominent control measure for stink bug with least toxicity. Southern green stink bug (Nezara viridula L.), brown stink bug (Euschistus servus Say) and brown marmorated stink bug (Halyomorpha halys Stal) were found during the observation. Abundance of stink bug was counted twice a week. Toxicity of insecticides was determined by counting the number of dead stink bugs in the field just after application of 12 hours. Among the insecticides, Azadirachtin (stored), Azadirachtin (fresh) and Curtap 50 SP reduces the stink bug infestation effectively. Azadirachtin (fresh), Azadirachtin (stored) and Emamectin benzoate 5 SG found least toxic to stink bug resulting 6.09, 24.68 and 30.02% mortality. Results of the study indicated that the botanical Azadiractin along with some chemical insecticides are effective for controlling sting bug infestation and also least toxic and safe for the other insects and environment.
