Abstract
The susceptibility of adult Halyomorpha halys to more than half of the insecticides used was high, but the mortality of this organism cyhalothrin, fluvalinate, flucythrinate, and thiodicarb was 30% or less. The susceptibility of adult Plautia crossota stali to most of the insecticides used, except flucythrinate, was also high. The susceptibility to insecticides was significantly different for the two species. Insecticides with a high residual effect on H. halys were fenitrothion, methidathion, and phenthoate in organophosphorus, and permethrin and bifenthrin in synthetic pyrethroid.
