The Field Efficacy and Influence Factor on Mass-Release of Trichogramma chilonison Sugarcane Borers
摘要
Abstract
To study the control effect and influence factor on Mass-release of Trichogramma chilonis on Sugarcane borers, some experiments were conducted in Beibu Gulf, Guangxi Province in 2015 and 2016. The experimental test area was more than 2000 hm2 and the results showed that the dead heart rate fell by 48.51% and the rates of bored internodes and dead tail fell by 51.26% and 51.56%, respectively; the final average yield increased by 21.77 t/hm2 and cane sugar by 1.83%. The effect of Trichogramma chilonis to control borers was reported, and the main influencing factors and relevant improving measures were analyzed.关键词
