Pesticide Toxicology and Pest Resistance Team Achieves New Research in Grassland Nocturnal Moth Prevention and Control Research

Nanhu News Network News (Correspondent Guo Zhimin) Recently, the research results of the pesticide toxicology and pest resistance team led by Professor Li Jianhong of the College of Plant Science and Technology of our university were titled "Insecticide susceptibility and mechanism of Spodoptera frugiperda on different host plants" in the Journal of Agriculture and Food Chemistry is published

Spodoptera frugiperda is a major migratory agricultural pest warned by the Food and Agriculture Organization of the United Nations (FAO) globally, which has spread rapidly since Myanmar invaded China's Yunnan Province in December 2018, posing a serious threat

Molecular mechanisms of differences in the sensitivity of pesticides in the strains of the grassland nocturnal moth raised by different hosts

Taking the field "maize-type" grassland moth population as the initial population, using rice and maize for 13 consecutive generations under indoor conditions, the researchers constructed two grassland moth strains that ate rice (rice strain) and maize (maize strain), and deeply explored the sensitivity difference mechanism

The study shows that although the "corn-type" grassland moth has the risk of harming rice, it can still be effectively controlled

Guo Zhimin, a doctoral student in the School of Plant Science and Technology, and Jin Ruoheng, a graduated doctoral student, were the co-first authors of the paper, Associate Professor Ma Kangsheng was the corresponding author of the paper, and Professor Li Jianhong, Associate Professor Wan Hu and Associate Professor He Shun participated in the guidance
