不同防治措施下2种诱捕器对苹果蠹蛾田间诱集效果比较

【目的】研究在无防治措施、迷向丝防治措施、迷向丝+化学综合防治措施、化学防治措施4种条件下,三角型诱捕器与纸型诱捕器的诱捕效果以及各防治措施的防治效果。【方法】2020年在石河子152团果园设置各防治区,悬挂2种诱捕器,在苹果蠹蛾发生和危害期调查各诱集点的苹果蠹蛾成虫的诱捕量及发生动态。【结果】纸型诱捕器在各防治措施下的诱捕效果均好于三角型诱捕器;三角型诱捕器在不同天气变化中的适应性好于纸型诱捕器;各防治措施中,迷向丝防治区的防治效果好于综合防治区,但差异未达到显著水平,化学防治区的防治效果最差。【结论】纸型诱捕器田间诱集效果明显好于三角型诱捕器(1 494只>933只),与化药防治相比,迷向丝防治苹果蠹蛾效果显著(P<0.05)。

Effects of Two Traps on Trapping Efficiency of Cydia pomonella under Different Control Measures

【Objective】 To explore the trapping effects of triangle traps and paper traps under the four conditions: the absence of control measure, synthetic sex pheromone measures, synthetic sex pheromone measures plus chemical comprehensive control and chemical control measures. 【Methods】 In 2020, various control areas were set up in the Shihezi 152th regimental farm orchard with two traps hung. From May 25 to July 27, the trapping amount and dynamics of Cydia pomonella (L. ) adults in each trap were investigated during the occurrence and hazard period of C.pomonella. 【Results】 The trapping effect of paper traps is better than triangle traps among all the prevention measures; the triangle trap had better adaptability in different weather changes than the paper trap; Among various control measures the control effect of synthetic sex pheromone control area was better than that of comprehensive control area, but the difference did not reach a significant level. The chemical control zone has the worst control effect. 【Conclusion】 The field trapping effect of paper traps is obviously better than that of triangle traps(1,494>933),Compared with chemical drugs,synthetic sex pheromone has significant effects on preventing and controlling C. pomonella(P<0.05).
