摘 要 ：强迫取食试验结果初步证实，甜菜大龟甲幼虫在藜科藜属杂草灰藜、小藜、杂配藜上能完成个体发育，取食甜菜时发育慢，死亡率高，幼虫个体间对甜菜的适应性差异大，赵冬代成虫出蛰期、一代卵及幼虫发生期与灰藜生长期的配合程度大于甜菜，但在田间灰藜等杂草数量少时，卵也可产生在甜菜叶片上，灰藜叶片被食光后幼虫转至甜菜为害。

Abstract:Compulsory feeding adaptation proved that the larvae of Cassida nebulosa, which feed the weeds - Chenopodium album, Ch. serotinum and Ch. hybridum of Chenopodiaceae, can finish their life cycle. Though they can feed on sugar beet-Beta vulgaris,but grow sl
