The study was conducted for the purpose to determine the efficiencies of alternative biopesticides to be used in the control against Halyomorpha halys. NeemAzal and water were used for the control. The most commonly-seen efficiency rates were determined to be 72 % with NeemAzal in the nymph stage. Seen efficiency rates were determined to be 38,5 % with 600 ml/100 l dose of Pyrethrum and 42 % with 500 g/100 l dose of Bacillus thuringiensis. The impact rate of the biopesticides performed against the adults, on the other hand, was found to be 42,3 % with 600 ml/100 l dose of SpruzitNeu and 33 % with 500 g/100 l dose of DipelDF. As a result, in the present study, it was observed that both pesticides were not to be much effective on the nymphs and adults of H. halys but NeemAzal is effected for control.
