Assessment and Management of Ecological Safety of Bt Cotton
(Second Prize, National Award for Science and Technology progress, China, 2010)

Scientists have been conducting long-term studies into how the cotton bollworm develops resistance to transgenic Bt cotton. Elucidation of resistance pathways has engendered new management strategies based on a multi-crop system (non-Bt host crops as a natural refuge), as well as techniques to control and delay the acquisition of resistance. The ecological impact of Bt cotton on target and non-target organisms has been studied for the establishment of new systems for insect pest management in areas where Bt cotton is grown.

Regional migration of cotton bollworm and its monitoring and forecasting technology (Second Prize, National Award for Science and Technology progress, China, 2007)

The geotype differentiation and regional facultative migration of cotton bollworm (Helicoverpa armigera) in China was clarified. The database of cotton bollworm occurrence and meteorological parameters was established, and its regional early-warning system being consisted of various forecasting measures and models was build. This technology has been applied in 14 major cotton-growing provinces in China, and enhanced the capability of monitoring and forecast of cotton bollworm.

Integrated Management of Wheat Stripe Rust (First Prize, National Award for Science and Technology progress, China, 2012)

The virulent fungus Puccinia striiformis causes stripe rust on many varieties of wheat in China. Technology has been developed that can pinpoint the source of outbreaks and forecast regional epidemics of stripe rust with the accuracy of close to 100%. Studies have elucidated the genetic basis for pathogen virulence as well as disease resistance in wheat cultivars. A strategy to identify outbreak sources and quickly control spread of pathogens has been widely implemented across the country, resulted in a significant reduction in crop losses, saving 9.3 billion yuan (US$1.5 billion).

Rice Blast Disease

Histone acetylation and deacetylation play an important role in the modification of chromatin structure and regulation of gene expression in eukaryotes. Results in this study demonstrate that histone deacetylase 701 negatively regulates innate immunity by modulating the levels of histone H4 acetylation of PRR and defense-related genes in rice.

Multi-target insecticides for controlling outbreak of resistant insect pests (Second Prize, National Award for Science and Technology progress, China, 2008)

Effective and new multitarget pesticides, such as 20% abarmectin-monosultap microemulsion, 3% beta cypermethrin-emamectin microemulsion, 20% fenvalarate-malathion emulsifiable concentrates and 15% abamectin-chlorpyrifos emulsifiable concentrates, have been developed to control insect pests with resistance to multiple insecticides. The insecticides demonstrate high cotoxicity efficacy in laboratory and are effective on controlling pests such as H. armigera, Cnaphalocrocis medinalis, Liriomyza sativae, and Nilaparvata lugens in the field. Over two million tons of the insecticides have been deployed to control crop resistant pests.
