Assessment on Efficacies of Different Regimen against Main Pests in Rice Fields
摘要
Abstract
The influences of different regimen on main pests ( rice planthoppers and Cnaphalocrocis medinalis), diversity of arthropod communitnies and rice yields were researched through field experiments. The results showed that the population decline rates and control effects of rice planthoppers in the plots using buprofezin and chlorantraniliprole (Regimen A) were significantly lower than those using imidacloprid and chlorpyrifos (Regimen B). The percentages of folded leaves (%) in the Regimen A plots were also significantly lower than those in Regimen B plots. The Shannon-Wiener index in Regimen A plots was higher than that in Regimen B plots, but the dominance index was lower than that in Regimen B plots, however, neither showed significant differences. The yield of Regimen A was 24 percent higher than that of Regimen B. It was apparent that Regimen A had a better control action on C. medinalis, with little effects on the arthropod community, and had higher yields than Regimen B.关键词
