The green rice leafhopper, Nephotettix cincticeps Uhler, has developed cross resistance to many carbamate insecticides in Japan and has caused serious problems in the protection of rice plants from the diseases that the hopper transmits. The worst problem is that this resistance has developed in areas where conventional or-ganophosphorus insecticides already have become useless. The resistance is mainly due to the reduced sensitivity of the hopper’s acetylcholinesterase (AChE) to carbamates and this finding has initiated research into the development of a new group of carbamates that would control the resistant green rice leafhopper.
