摘要: Chlorantraniliprole was introduced into China from 2008 as a novel insecticide to control the rice stem borer, Chilosuppressalis (Walker). Cotesia chilonis (Matsumura) is the major parasitoid of C. suppressalis. We collected sevenpopulations of C. suppressalis and two populations of C. chilonis in different locations in China in 2009 to investigate thelethal effects of chlorantraniliprole on them. The populations of C. suppressalis from different regions showed variousLD50 values ranging from 2.00 to 18.70 ng per larva. Chlorantraniliprole has negligible acute contact toxicity (LC50>500 mgL-1) to C. chilonis and its oral toxicity is also much lower than that of fipronil (>2 800-fold difference in LC50). The resultsindicated that chlorantraniliprole is a good alterative in rice integrated pest management (IPM) programs. The susceptibilitydata of C. suppressalis will be useful for monitoring resistance levels in future.
