Abstract
The development of insecticide resistance in rice brown planthoppers and its mechanism were studied. The susceptibility of malathion- and MTMC-selected strains to malathion decreased to 1/39 and 1/25 of the initial level after 45 selections, respectively, while that to MTMC decreased to 1/2. 5 and 1/4. 2. These selected strains were more susceptible to synthetic pyrethroids than the parent strain. K 1 and K2 showed high synergism to the selected strains, and also inhibited the decomposition of malaoxon. Malathion resistance in the malathionor MTMC-selected strains was suggested to be caused by high degradative activity to malathion and malaoxon. The mechanism of MTMC resistance in the MTMC-selected strain was presumed to be caused by low sensitivity of acetylcholinesterase.
