摘要
【目的】评价黄色诱虫板在测报和防控稻纵卷叶螟(Cnaphalocrocis medinalis)中的作用和效果,为测报稻纵卷叶螟的发生和绿色防控其危害提供依据。【方法】采用黄色诱虫板诱集法与常规赶蛾法调查结果比较,确定其测报的可靠性;防治效果采用测产法,将黄色诱虫板处理的水稻产量同杀虫剂处理田块产量进行比较。【结果】3个水稻品种受害情况均表现为7月份较轻,8、9月份相对较重;8月份黄色诱虫板诱集到的稻纵卷叶螟成虫最多,2周内诱集的成虫数量最高达53头/板,平均每天诱集数量为(2.86±0.43)头/板;黄色诱虫板的高度在一定程度上影响着稻纵卷叶螟成虫诱集的效果。黄色诱虫板下部距离水稻冠层越近,诱集效果越好;同赶蛾数据相比,黄色诱虫板预测稻纵卷叶螟的发生具有一定的准确性和可靠性;黄色诱虫板对于稻纵卷叶螟成虫具有一定的诱杀作用,防治效果等于或好于使用杀虫剂田块的防治效果。【结论】通过对黄色诱虫板测报和防控稻纵卷叶螟的效果进行评价,认为黄色诱虫板在测报和防治稻纵卷叶螟的发生具有一定的应用前景。
[Objective] The forecasting and controlling effects of the yellow sticky card on rice leaffolder （Cnaphalocrocis medinalis） were evaluated, which would provide a scientific basis for managing this insect pest. [Method] The trapping method of yellow sticky card and driving moth method were compared to test the forecasting reliability. The production of rice harvested from the field both sprayed insecticides and fixed the yellow sticky card was tested to testify the control effect of the yellow sticky card. [Result] The rice was seriously damaged by C. medinalis in August and September and lightly in July. The number of C. medinalis trapped was the highest in August, and （2.86±0.43） adults were trapped on per card every day on average. The height of the yellow sticky card was important for trapping C. medinalis. The closer the distance from the lower fringe of the yellow sticky card to the top of the rice was, the more rice leaffolders were trapped. It was reliable to forecast the occurrence of C. medinalis by comparing the data between the yellow sticky card and driving moth. The yellow sticky card could trap and kill C. medinalis, and its control efficiency was equal or higher than using insecticide. [Conclusion] The yellow sticky card is a promising method in forecasting and controlling C. medinalis.
