粘虫喜欢在麦田的枯叶上产卵。根据粘虫成虫的这一习性,外地采用粟谷草把诱蛾产卵,然后处理草把,防治效果良好。我们结合当地条件,于1974年3月19—30日用稻草把与麦秸把进行诱集粘虫产卵的试验,在麦田里各插5个把子,结果是稻草把共有13块卵块,而麦秸把无卵块。与此同时,我们还进行了稻草把夹糖浆麻袋片与不夹糖浆麻袋片的诱粘虫产卵比较试验,也是各插5个把子,结果是夹糖浆麻袋片的共有25块卵块,总卵粒数1,322粒,而不夹糖浆麻袋片的只有12块卵块,总卵粒数757粒。有的地方在稻草把上插一枝扁柏树枝,可以大大提高诱蛾产卵的效果。
Army worms like to lay eggs on dead leaves in the wheat fields. According to this habit of armyworm adults, the field uses millet grass to spawn the moth, and then handle the grass, the control effect is good. In the light of local conditions, we experimented with the use of straw and wheat straw to induce eggs to be trapped in the armyworms on March 19-30, 1974, with five knives in each of the fields, resulting in a total of 13 eggs in the straw, Wheat straw no egg. In the meantime, we also conducted a straw-to-sugar syrup sack film and a non-syrup sack film spawning comparison test, but also inserted five of each handle, the result is a folder of syrup sacks a total of 25 eggs, total The number of eggs is 1,322, while there are only 12 eggs without the syrup sacks, the total number of eggs is 757. In some places in the straw to insert a hinoki branches, can greatly enhance the effect of lure eggs.
