摘　　要：为了筛选对草地螟具有引诱效果的寄主植物,采用"Y"型嗅觉仪、取食选择及产卵选择法进行了草地螟对灰菜、大豆、苜蓿、向日葵和甜菜的选择行为。结果显示:幼虫喜欢选择取食灰菜;成虫产卵偏好性顺序为:灰菜>大豆>苜蓿>向日葵>甜菜。与对照相比,灰菜、大豆、苜蓿和向日葵的粗提物对雌成虫均具有显著的引诱作用。两两比较时,灰菜粗提物的引诱作用与其他4种植物的粗提物相比均达到显著水平。灰菜及其粗提物对草地螟具有明显的引诱效果。In order to screen the host plants which had induced effects on Loxostege sticticalis L., the Y-tape olfactometer, feeding and oviposition choice method were used to measure the behavior responses on 5 host plants. The results showed that： the tendency of female adults and larvae of L. sticticalis to 5 species of host plants were performed in laboratory, the larvae preferred to feed on lambsquarter leaves. The number of female adults laying-eggs on lambsquarter ranked No. one, followed by soybean, alfalfa, sunflower leaves and sugarbeet. Compared with contrast, the crude extractings from lambsquarter, soybean, alfalfa and sunflower leaves had significantly temptation to female adults. Pairwise comparison showed that the orientating preference to crude extractings from lambsquarter was significant than the rest of the four. Lambsquarter and the crude extract had obvious effect on the moth of L. sticticalis.
