苹果蠹蛾成虫对不同波长黑光灯的趋性研究初探

A Preliminary Discussion on Taxis of Cydia Pomonella (Linnaeus) Adults to the Different Wavelength of Black Light Lamp

在新疆农业大学校园内9个条件较一致的地点设置监测点,筛选和定制8个不同波长的黑光灯进行苹果蠹蛾的诱集试验,观察分析苹果蠹蛾对不同波长黑光灯的趋向程度。结果发现苹果蠹蛾对黑光灯最敏感的波长为351 nm,11次试验共诱集到苹果蠹蛾成虫69头,与其他波长的灯管在诱集数量上差异极显著;3个时间段内诱集总量比较表明,黑光灯诱集效果最佳的时间段为黄昏后2 h,在这个时间段里诱集到的苹果蠹蛾数量占诱集总数量的69.38%。

Nine monitoring sites with the same condition were set on the campus of Xinjiang agricultural university,8 black light lamps of different wavelength were selected and customized to observe the tropistic degree of Cydia pomonella（Linnaeus） adults to these black light lamps,then analyse the collected data.The results indicated that the sensitive wavelength of the Cydia pomonella（Linnaeus） adults to black light lamps is 351 nm,and total 69 adults were trapped within 11 experiments,which had significant difference compared with the other black light lamps.Based on the trapped number,the optimum time of trapped in the 3 phases is that after 2 hours at the dusk.On this condition,the trapped numbers of Cydia pomonella（Linnaeus） adults accounted for 69.38% of the totals.
