大豆食心虫两种性诱芯和诱捕器田间诱蛾效果

摘要

为了改进大豆食心虫诱捕防治技术，采用两种性诱芯（橡胶塞性诱芯和塑料细管性诱芯）和两种诱捕器（水盆和粘胶板），研究了其诱蛾效果。结果表明：橡胶塞性诱芯的平均诱蛾量是塑料细管性诱芯的12．77倍，差异显著；单盆日最大诱蛾量达9．56倍，差异显著。三角型粘胶板的平均诱蛾量是水盆的1．44倍，差异不显著；单盆日最大诱蛾量是1．51倍，差异也不显著。建议目前生产上使用橡胶塞性诱芯，优先考虑使用粘胶诱捕器。%　　In order to improve the mass-trapping technique ,trapping effect of two types of the sex pheromone lures and traps were evaluated in field .The results showed that :mean and max numbers of moths captured at water trays baited by the rubber stopper sex pheromone lures were 12 .77 and 9 .56 times higher than that by the plastic tubes sex pheromone lures ,respectively .Statistical analysis showed that both of the catch differences were significant(P 0 .05) .Currently ,it is suggested to use a rubber stopper sex pheromone lures and the triangular glue board trap in practical control .
