摘要
性诱剂可用于诱集雄虫,干扰雌、雄虫交配从而抑制害虫种群,性诱剂的应用效果受诱捕器类型、悬挂高度等多种因素影响。本研究比较了性诱捕器不同类型(桶型诱捕器1、桶型诱捕器2、黏胶型诱捕器)和不同悬挂高度(高于水稻上部叶片20 cm、50 cm、80 cm)对二化螟(Chilo suppressalis)雄虫的诱集效果,结果表明不同类型诱捕器诱集到的二化螟数量存在差异,整体来看桶型诱捕器1>桶型诱捕器2>黏胶型诱捕器,但是未达到显著水平(P=1.866,F=0.165)。不同悬挂高度诱捕器诱集到的二化螟成虫数量存在显著差异(df=2,F=9.152,P=0.001;纽康诱芯df=2, F=6.677,P=0.004),随着诱捕器悬挂高度的增加,诱集到的二化螟成虫数量逐渐减少,其中以悬挂高度为20 cm的处理诱集效果最好,不同高度处理得到的二化螟动态曲线基本一致,说明诱捕器高度对监测二化螟成虫高峰期影响不大。
Using sex pheromone can suppress the insect population by attracting male insects and disturbing mating of insects. The application effect of sex attractants is affected by many factors, such as the type of trap, hanging height and so on. In this study, different types(barrel-type trap 1, barrel-type trap 2, and adhesive-type trap) and suspension heights(20 cm, 50 cm, 80 cm above the upper leaf surface of rice) of sex traps were compared to trap the male of Chilo suppressalis. The results showed that there were differences in the number of Chilo suppressalis trapped by different types of traps. As a whole, barrel-type trap 1 > barrel-type trap 2 > adhesive-type trap, but it did not reach a significant level(P=1.866, F=0.165). There was significant difference in the number of adults of Chilo suppressalis trapped by different hanging height traps(df=2, F=9.152,P=0.001;Newcon lure core df=2, F=6.677,P=0.004). As the height of the trap increased, the number of trapped adults gradually decreased. The best suspension height of sex attractant lure on Chilo suppressalis in rice fields was 20 cm. The dynamic curves of Chilo suppressalis obtained from different height treatments are basically the same, which shows that the height of trap has little effect on monitoring the adult peak of Chilo suppressalis.
