| 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 slow, resulting in high death rate . Both the hibernating time of revival of adults and the appearance of first brood eggs are synchronized with the period of growth of Chenopodium album better than with that of Beta vulgaris,they lay eggs on the leaves of Beta vulgaris only when there are rarely weeds such as Chenopodium album in the vicinity. |
