Abstract
Several insect pests cause serious damage and pose a great threat to the cultivation of rice in many Asian countries. Chemical insecticides have been used as the leading control measure of pest management strategies in the rice ecosystem to control insect pests. But, recent findings indicated that intense insecticide application caused resistance development in a large number of insect pests. The striped stem borer and the three rice hopper species, which are the most frequent and destructive pests in rice fields, have shown various levels of resistance against commonly used insecticides. This eventually becomes problematic in designing pest management strategies and may threaten to obtain high-efficiency insecticides to control rice pests. Different insecticide resistance mechanisms governing resistance development in rice pests have been reported. However, no latest and sufficient information on reduced insecticide toxicity and related resistance mechanisms in rice pests has been summarized. Here, we reviewed the insecticide resistance status in response to diverse insecticides in four rice pests recorded in the last five years. Furthermore, this article discussed the detailed insecticide resistance mechanisms such as target-site insensitivity and the metabolic resistance mechanisms associated with resistance development in rice pests.
