Basic research on the outbreak mechanism and sustainable management of rice planthoppers

Key Words：rice planthopper, outbreak mechanism, sustainable management

Abstract：         Rice planthoopers have been the most destructive pests for food security and the chemical pesticides used to control them are affecting ecological and food safety in China. Therefore, integrated approach for intensive rice production and sustainable control of rice planthoppers has been becoming of the most      important task. The molecular mechanism for the pests adapting intensive rice ecosystem and ecological bases for integrating technology for intensive agriculture and sustainable pest management would be studied to improve understanding. 6 subprojects, including migration and temporalspecial dynamics of rice planthopper populations; genetic bases of rice resistance to planthoppers and planthopper virulence; ecological and molecular mechanism of epidemic of rice virus diseases transmitted by planthoppers; ecological toxicology of pesticides on planthoppers and their natural enemy; data analysis for planthopper genome and techniques for identifying functional genes and regulating function and relevant mechanism of rice ecosystem on planthopper population development, will be further explored to provide theoretical and technical bases for establishing outbreak monitoring and warning systems for rice planthoppers and virus diseases, development of resistant varieties and program for sustainable management of these pests.
