Insecticides susceptibility of adults of water strider, Gerris latiabdominis (Hemiptera: Gerridae)

The insecticides susceptibility of adults of the water strider, Gerris latiabdominis, was studied. The water strider is quite susceptible to insecticides and the LD50 values of organophosphates, carbamates, pyrethroids, nereistoxins, and neonicotinoids ranged from 0.24 to 31.6μg/g. The LD50 values for fenitrothion, BPMC and PHC were low compared to those for several Hemipteran insect pests of rice paddy.
