In this study,we conducted a risk assessment on non-target insects exposed to lambda-cyhalothrin·dinotefuran 15％oil dispersion,following the Guidelines for Environmental Risk Assessment for Pesticide Registration.Both lambda-cyhalothrin and dinotefuran were found to pose unacceptable risks to Apis mellifera and Bombyx mori.Furthermore,unacceptable risk levels associated with lambda-cyhalothrin and dinotefuran were observed for Trichogramma ostriniae and Coccinella septempunctata,both within and outside the treated field.In conclusion,the risk of lambda-cyhalothrin·dinotefuran 15％oil dispersion to non-target insects was unacceptable.To mitigate these risks,we recommend avoiding the collection of mulberry leaves from adjacent rice fields for silkworm feeding,limiting pesticide application during the flowering period of citrus trees,adjusting application timing to avoid overlap with bee release schedules,and applying pesticide during seasons when populations of parasitic and predatory natural enemies are low.
