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 600ml/100l dose of Pyrethrum and 42% with 500g/100l 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/100l dose of Spruzit®Neu and 33% with 500g/100l dose of Dipel®DF. 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.
