草地螟食性杂，但发生分布对寄主和环境有较强选择性。１９８８年调查，一代卵主要产在杂草较多的农作物田，一般以叶片较短、叶面较光滑的阔叶植物如甜菜、亚麻、豆类、马铃薯等农作物和灰菜、蓄、猪毛菜等杂草上产卵量高。一代幼虫滞育越冬，也以杂草密度较大的农作物田为主。然而，一代幼虫的越冬比率，年度间差异较大。初步分析，７～８月份气温偏低，日照较少，有利一代幼虫滞育越冬。这一结论为当地草地螟的中长期预报和综合防治提供了依据。 Grasshopper dietary miscellaneous, but the distribution of the host and the environment has a strong selectivity. 1988 survey, a generation of eggs is mainly produced in weeds more crop fields, generally with shorter leaves, leaves more smooth broadleaf plants such as sugar beet, flax, beans, potatoes and other crops and vegetables, storage, pig hair Vegetables and other weeds on the spawn. Diapause overwintering generation of larvae, but also to weed density of the larger crop fields. However, the overwintering rates of the first generation larvae vary widely from year to year. Preliminary analysis, 7 ~ August low temperature, less sunshine, beneficial to the larvae diapause wintering. This conclusion provides a basis for medium and long-term prediction and comprehensive prevention and control of local meadow moth.
