田间罩笼人工接蛾试验结果表明，不同生育阶段的玉米和大豆对棉铃虫产卵选择表现出明显差异。在每区组８ 对和１６ 对成虫接蛾密度下，开花期玉米的卵分布率分别为９０１ ％ 和８６１ ％ ，落卵部位主要集中在雄穗和叶片的正面；拔节期玉米的卵分布率分别为９６ ％ 和１３５ ％ ，落卵部位主要集中在叶片的正面；苗期玉米的卵分布率分别为０３ ％ 和０４ ％ ，落卵部位全部集中在叶片的正面。相应地，在两种接蛾密度下，开花结荚期大豆的卵分布率分别为９０１ ％ 和７２７ ％ ，落卵部位主要集中在叶片的正反面及嫩头上；臌粒成熟期大豆的卵分布率分别为６１ ％ 和２１７ ％ ，落卵部位主要集中在叶片的反面及豆荚上；分枝期大豆的卵分布率分别为３８ ％ 和６０ ％ ，落卵部位主要集中在叶片的正反面。 The experimental results of artificial moth in field cage showed that corn and soybean at different stages of growth showed obvious differences in selection of cotton bollworm. At the density of 8 pairs and 16 pairs of adult moths per group, the egg distribution rate of flowering maize was 901% and 861%, respectively. The eggs were mainly located on the front of tassels and leaves. The egg distribution rate was 96% and 135% respectively, and the egg lay mainly on the front of the leaf. The egg distribution rate of seedling corn was 03% and 04%, respectively. The front of the blade. Correspondingly, the egg distribution rate of flowering podding soybean was 901% and 727% at the two kinds of moth densities, respectively. The eggs were mainly concentrated on the obverse and reverse sides and tender head of the leaves. The egg distribution rate of soybean was 61% and 217%, respectively. The egg lay mainly on the opposite side of the leaf and pods. The egg distribution rate of branching soybean was 38% and 60% Oviposition site mainly in the positive and negative leaves.
