Comparative Test on Trapping Effects of Different Sex Pheromone Luresto Spodoptera litura in Guangzhou

摘要

摘要: 【目的】比较不同性诱剂诱芯对广州地区斜纹夜蛾的引诱效果。【方法】在广州地区田间进行 4种不同厂家的斜纹夜蛾诱芯（NB、QZ、BJ、ZZ）诱捕效果的测定，作物、田间管理措施等其他外界因素基本一致的情况下，每隔 1 周对诱集虫口数进行一次收集，每隔 4 周更换 1 次诱芯。对 4 种不同厂家的斜纹夜蛾诱芯的诱捕虫口数进行差异显著性分析。【结果】试验期 NB、QZ、 BJ、ZZ 4 种诱芯每瓶诱蛾总数分别为 2 402、786、394、123 头，诱芯 NB 是诱芯 QZ 的 3.05 倍、诱芯 BJ 的 6.09 倍、诱芯 ZZ 的 19.53 倍；平均每日每瓶诱蛾数分别为 26.1、8.5、4.2、1.3 头，诱芯 NB 是诱芯 QZ 的 3.07 倍、诱芯 BJ 的 6.21 倍、诱芯 ZZ 的 20.08 倍。【结论】诱芯活性：NB ＞ QZ ＞ BJ ＞ ZZ，半衰期时间：NB（32.25d）＞ QZ（25.1d）＞ BJ（16.04d）＞ ZZ（12.1765d）。

Abstract: 【Objective】A comparison of the attractive effects of different sex attractants on Spodoptera litura in Guangzhou was conducted. 【Method】 The trapping effects of four kinds of S. litura lures (NB, QZ, BJ, ZZ) from different manufacturers was measured in fields of Guangzhou. When other external factors, such as crops and field management measures, were basically the same, the number of S. litura trapped was collected every other week, and the lures were replaced every four weeks. The significant difference analysis was conducted on the number of S. litura trapped by the four lures for S. litura. 【Result】The total number of S. litura attracted by NB, QZ, BJ and ZZ were 2402, 786, 394 and 123 respectively. The number of S. litura trapped by lure NB was 3.05 times of that by lure QZ, 6.09 times of that by lure BJ and 19.53 times of that by lure ZZ. The average number of S. litura attracted per bottle per day was 26.1, 8.5, 4.2 and 1.3 respectively. The number of S. litura trapped by lure NB was 3.07 times of that by lure QZ, 6.21 times of that by lure BJ, and 20.08 times that by lure ZZ.【Conclusion】 The lure activity: NB > QZ > BJ > ZZ; and the half-life time: NB(32.25d) ＞ QZ(25.1d) ＞ BJ(16.04d) ＞ ZZ(12.1765d).
