稻-鸭共生技术对稻水象甲的生态控制效应

[目的]探讨稻水象甲的生态防控措施。[方法]通过在稻田生态食物链的环节中放养鸭子,研究了稻-鸭共生对稻田生态系统中稻水象甲成虫发生规律及其防控效果的影响。[结果]稻-鸭共生对稻水象甲具有显著的生物态控制效应,其中对稻水象甲成虫的防效达92.56%,对水稻白叶率的防效达98.15%,均优于化学防控效果。[结论]稻-鸭共生特别适合对如稻水象甲等繁殖力强、化学防治难度大的虫害,为生态控制稻水象甲提供了借鉴。

Effect of Rice-duck Symbiotic Technology on Ecological Control of Rice Water Weevil

[Objective] The aim was to investigate the ecological control techniques of rice water weevil.[Method] Effects of rice-duck symbiotic technology on the occurrence regularity and the ecological control of rice water weevil were studied by breeding ducks in ecological food chain of rice field.[Result] There was noticed effect of the rice-duck symbiotic technology on rice water weevil,among them the adults of rice water weevil and the ill leaf rate of rice were controlled by 92.56% and 98.15% respectively,which was better than chemical control techniques.[Conclusion] The rice-duck symbiotic technology is very suitable to control such pests as rice water weevil with strong fecundity and hard chemical control,and it offers a new way for the ecological control of rice water weevil.
