性诱导和黑光灯在甜菜夜蛾和斜纹夜蛾测报上的应用效果比较

Comparison of effects of sexual attractants and blacklight traps applied to forecasting Laphygma exigua and Prodenia litura moths

在大葱田设置甜菜夜蛾、斜纹夜蛾性诱剂进行成虫诱测,并与黑光灯诱测进行比较。结果表明:性诱剂下的诱测效果明显好于黑光灯,诱蛾总量是黑光灯的5.39～96.71倍,且峰次突出,有蛾天数多,能有效提高两虫监测和预报的准确性。

The experiments of trapping L. exigua and P. litura moths with two sexual attractants and blacklight traps were carried out in welsh onion fields in order to compare the effects of sexual attractants and blacklight traps applied to forecasting both moths. The results showed that the trapping effect of the sexual attractants was obviously better than that of blacklight traps. The total quantity of both moths trapped with the sexual attractants was 5.39-96.71 times as many as that trapped with blacklight traps, and trapping both moths with the sexual attractants was more prominent in peak stage and longer in duration than trapping with blacklight traps. So application of the sexual attractants could effectively improve the accuracy in monitoring and forecasting of both moths.
