不同枣粘虫诱芯的诱虫效果筛选试验

Screening Experiment of Different Ancylis Sativa Lure on the Trapping Insect Effect

通过对不同种类的枣粘虫诱芯(A、B、C、D、E等共11种诱芯)田间筛选试验,筛选出诱蛾效果最佳的诱芯为L,累计诱蛾量为L>M>A>K>B>C>G>F>E>H>D;根据日诱蛾量掌握了第3代枣粘虫发生动态,通过蛾峰、卵发育历期推测幼虫初孵盛期和盛期,及时预测预报,指导科学防治,并可推断越冬蛹基数,为来年预测枣粘虫发生程度提供参考依据。

The screening experiment was conducted using eleven different proportion lure of Ancylis sativa, （A, B, C, D, E, and so on）. The best trapping effect was the L lure. The accumulative quantity of trapping moth followed the order as： L〉M〉A〉K〉B〉C〉G〉F〉E〉H〉D. The occurrence dynamics of the third generation Ancylis sativa were determined through daily quantity of trapping moth. Based on the moth peak and egg developmental duration, the larva first hatching acme and acme were deduced, and forecast and scientifically control were made. At the same time, the number of overwintering pupa was also speculated, which in turn provided the basis for determining occurrence degree of Ancylis sativa in the next year.
