用各种金属喷镀袋保存谷物,对谷象和谷蛾的繁殖抑制效果进行了实验。1、对谷象的繁殖抑制效果大小的顺序是:镍、铬、黄铜、铝、不锈钢。2、用金属喷镀袋保存,可推迟次世代的谷象出现,并有脱出时间长的特性。3、对谷蛾的繁殖抑制效果大小的顺序是:镍、铬、铝、黄铜。因此,如果是以防虫为目的时,使用镍或铬的喷镀袋为最适宜。4、用金腻喷镀袋保存谷物,虽有抑制害虫繁殖的特性,但不能完全防除,所以有必要通过与其它的方法并用来提高其效果。
Cereal was preserved in various metal-sprayed bags to test the effect of inhibiting the growth of Gall and Elephantine moth. 1, the inhibitory effect of the size of the population of astrology is: nickel, chromium, brass, aluminum, stainless steel. 2, with metal spray bag to save, can be delayed next generation of cereal elephant appear, and a long time prolapse characteristics. 3, the inhibitory effect on the propagation of moth moth size order is: nickel, chromium, aluminum, brass. Therefore, if it is to pest control purposes, the use of nickel or chromium spray bag is the most suitable. 4, with gold-plated spray bag to save grain, although the inhibition of pest breeding characteristics, but can not be completely controlled, it is necessary to pass and other methods and used to improve its effectiveness.
