我们从1973年,对粘虫的生活习性进行了系统观察,发现粘虫有强烈的趋向苕子田内稻草把产卵的特性。经5年10次试验,平均草把累计卵量:苕子田的稻草把为265.6块,麦田仅81.6块。为了进一步验证这一规律,1975年在同一块麦田的稻草把中,分别夹进新鲜苕子或红花草(即紫云英)与不夹的进行比较,结果夹苕子草把的诱卵量最多。十天10把累计卵量:夹苕子的22块,夹红花草的4块,不夹的 From 1973, we systematically observed the habits of armyworms and found that armyworms had a strong tendency to spawn in straw fields. After 5 years of 10 tests, the average grass to the cumulative amount of eggs: shizi straw to 265.6, only 81.6 wheat fields. In order to further verify this law, in 1975 in the same piece of straw in the wheat field, were caught in the fresh prickly heat or safflower (ie, Chinese milk vetch) compared with no folder, the results clip folder grass to the amount of eggs most. Ten days total of 10 eggs: clip raccoon 22, 4 clip saffron, not folder
