不同诱捕方法对玉米螟的诱捕效果比较研究

[目的]寻找更加准确测报预报玉米螟发生情况的方法。[方法]设玉米螟性诱剂试验田,并在附近设虫情测报灯,对比利用性诱剂和虫情测报灯对玉米螟的诱捕效果。[结果]性诱剂诱捕玉米螟较虫情测报灯所诱蛾量多,且两种测报方法测出的各代成虫高峰期与历期推算的吻合度高。[结论]利用性诱剂诱捕玉米螟丰富了病虫测报预报手段,提高了预报测报的准确度。

Comparative Study on Forecasting Effect of Different trapping Methods on Ostrinia nubilalis

[ Objective ] To search the best predicting and forecasting way to the occurrence of Ostrinia nubilalis. [ Method ] Sex attractant ex- perimental plot and pest forecast lamp for Ostrinia nubilalis were set, the effect of sex attraetant and pest forecast lamp on Ostrinia nubilalis was comparative studied. [ Result] The trap catches by sex attractant was more than by pest forecast lamp, and the adult occurrence peak of Os- trinia nubilalis in different generations by sex attractant and pest forecast lamp was consistent to past time calculation. [ Conclusion] The meth- od of forecasting Ostrinia nubilalis was enriched by sex attractant, and the accuracy of forecasting Ostrinia nubilalis was improved.
