本文进一步探索了榆蓝金花虫中毒后,残存种群的发育、繁殖情况,在打乱榆蓝金花虫的种群结构、消弱其繁殖力和生存力方面,取得了成功,林间应用效果良好。a.灭幼脲1号的施用能在下一虫态或子代产生药理效应,成虫期可引致雌虫不育,所产之卵不孵化率为100％;幼虫期个体发育至成虫,产卵量降低60％.b.经处理的幼虫发育受阻,使龄期延长2～4d不等,残存种群发育、变态无明显的高峰期,结构紊乱.c.林间常规MV喷雾,亩施药量4.27～8.54g(折纯品),虫口减退率在94.5％以上。
This article further explored the elm Eugenia crassipes poisoning, the survival and reproduction of the remaining populations, in order to disrupt the population structure of the genus Ulmus, to weaken the fertility and viability, and achieved success, the effect of forest applications good. a. The application of diflubenzuron 1 can produce the pharmacological effects in the next insect or progeny. The adult stage can lead to infertility of the female, and the egg hatched rate is 100%. The adult larvae develop into adults and spawn The amount decreased by 60% .b. The development of obstructed larvae was delayed, the age was extended 2 ~ 4d, residual population development, metamorphosis no obvious peak, structural disorders.c. 4.27 ~ 8.54g (pure product), the reduction rate of insects was above 94.5%.
