防治粘虫,将糖蜜诱杀成虫作为一项措施在生产上已经应用。有些年份,部分地区曾开展过粘虫成虫大面积的诱杀防治,但防治成本较高,效果不显著。在诱杀成虫以后,仍需防治幼虫。近年来,在粘虫预测预报工作中,我们还发现诱蛾量与田间幼虫发生量悬殊很大。诱蛾器诱到的第一代成虫数量很少,发蛾高峰蛾量亦明显偏少,而田间幼虫发生密度却很大,对作物 Prevention and control of armyworms, molasses trap adult as a measure of production has been applied. In some years, large-scale trapping and killing of adult armyworm adults have been carried out in some areas, but the prevention and treatment costs are relatively high, and the effect is not obvious. Larvae are still required after the trapping and killing of adults. In recent years, in the armyworm prediction and forecasting work, we also found that there was a great disparity between the amount of induced moth and the occurrence of field larvae. The number of first-generation adults induced by the decoy was very low, the number of the moths in the moths was significantly less than that of the moths, while the density of the field larvae was very high.
