菜蚜是我市蔬菜上的主要害虫,历年危害猖獗,对蔬菜的优质高产威胁很大。1976年我们根据蚜虫测报办法以及省农科所植保室介绍的棉区灭蚜经验,利用蚜虫趋色的特性,在蔬菜上推广了黄板诱蚜。据不完全统计,全市插放黄板两万多块,均获得了一定防治效果。10月中旬末,我们对87块大白菜、腌菜、萝卜地进行防蚜效果考查,结果是放足黄板(每亩8块左右)管理好的田块,防蚜效果显著,有蚜株率大幅度减少,病毒病发病率下降,病情指数减轻。由于插放黄板有效地消灭了迁飞的有翅蚜,压低
Vegetable aphid is the main pests on vegetables in our city, rampant over the years, the threat of high quality and high yield of vegetables. In 1976, based on the aphid reporting method and the experience of cotton aphid infestation introduced by the Provincial Department of Agriculture and Plant Protection, we used the characteristics of aphid fading to promote the yellow-lure aphid in vegetables. According to incomplete statistics, the city inserted more than 20,000 pieces of yellow board, all obtained certain control effects. At the end of October, we tested the anti-aphid effect of 87 Chinese cabbages, pickles and radishes. The results showed that the field was well-managed with the yellow board (about 8 per acre) Significantly reduce the rate of decline in the incidence of viral diseases, reduce the severity index. As inserted yellow plate effectively eliminated the migration of a winged aphids, down
