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。越冬代成虫出蛰期、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,卵也可产在甜菜叶片上,灰藜叶片被食光后幼虫转至甜菜为害。 Forced feeding test results initially confirmed that large beetle turtles in Chenopodium Chenopodiaceae quinoa, quinoa, quinoa quinoa to complete the development of individuals, slow development and mortality when eating beet, larvae individuals between beet The adaptability difference is big. Overwintering generations of adults out of the hibernation period, the generation of eggs and larvae occurred with the stage of growth of quinoa than sugar beet, but in the field of weeds and other weeds in small quantities, the eggs can also be produced in the beet leaf, quinoa leaves were eaten After larvae turn to beet harm.
