2010年在通海县开展的4种不同性诱剂产品对甜菜夜蛾的诱杀效果比较试验结果表明,不同性诱剂产品对甜菜夜蛾的诱杀效果差异显著。在有效试验期以诱芯A的平均日诱蛾、最高单日诱蛾效果最好,显著高于诱芯C和诱芯D,也高于诱芯B。但在不同时间段内,4种甜菜夜蛾性诱剂产品的诱捕性能表现各异。其中在1～20 d内,诱芯B的平均诱蛾量最高,诱芯A和诱芯C平均诱蛾量相近,且三者都显著高于诱芯D;在21～60 d内,诱芯A的平均诱蛾量最高,诱芯B和诱芯D平均诱蛾量相近,且三者都高于诱芯C,诱芯A显著高于诱芯C。4种性诱剂对甜菜夜蛾的田间持续期亦有所差异。以诱芯A和诱芯B的持续期最长,达到60 d、59 d,诱芯C最短为33 d,诱芯D为41 d。
The results of the trapping and killing effects of four different sexually attractant products on beet armyworm in Tonghai County in 2010 showed that the trapping effects of different sexually attractant products on beet armyworm were significantly different. In the effective test period, the average daily moth induced by the entrainer A was the highest, and the highest one-day entomology was the best, significantly higher than that of the entrained C and the entrained D, and higher than the entrained B. However, the trapping performance of the four beet armyworm sex-attractants varied in different time periods. Among them, the average number of induced moths in induced core B was the highest within 1 ~ 20 d, the average number of induced moths in induced core A and induced core C were similar, and all three were significantly higher than that of induced core D. Within 21-60 days, The average number of induced moths in core A was the highest, and the average number of induced moths in induced core B and induced core D were similar, and the three were higher than that of the induced core C, and the induced core A was significantly higher than the entomogenous core C. The four species of lures on beet armyworm field duration are also different. The longest duration of entrapping A and B was 60 days and 59 days, the shortest of entrained C was 33 days and the entrained D was 41 days.
