苹果绵蚜(Eriosoma Lanigerum Haus-mann)一年发生多代,年中春夏、秋两次发生为害高峰,秋季发生规律是:9月中旬开始增殖,10月出现全年第二次发生为害高峰。苹果采收后喷药防治,不仅控制秋季苹果绵蚜为害,还可大大压低越冬绵蚜基数,控制来年为害。 1994年我们进行了40％蚜灭多乳油防治苹果绵蚜药效试验。现将试验结果报告如下。 Eriosoma Lanigerum Haus-mann occurs many times in one year, and the peak occurs in spring, summer and autumn in mid-year. The law of fall is that it begins to proliferate in mid-September and the second peak occurs in October . Apple harvest spray control, not only to control autumn apple aphid harm, but also greatly reduce the base of winter overwinged cotton aphid, controlling the next year harmful. In 1994, we conducted a 40% aphid-resistant emulsion control apple aphid drug efficacy test. The test results are reported below.
