食料对大猿叶虫山东种群滞育和生物学特性的影响

The effects of host-plants on diapause induction and biology in the Sandong population of the cabbage beetle, Colaphellus bowringi

在25℃、LD12︰12条件下,大猿叶虫山东种群取食九种不同食料植物,以精半黄小白菜喂养的大猿叶虫山东种群滞育率最低,与其他八种食料有显著差异,而这八种食料之间无显著差异。大猿叶虫山东种群取食九种不同食料植物,蛹重没有显著差异,而幼虫发育历期、雌虫寿命、每雌总产卵量、平均产卵量均有显著差异。

At 25℃ and LD12：12, Shandong population of the cabbage beetle, Colaphellus bowringi was fed on different nine host-plants. The incidence of diapause was highest when fed with the Jingbanhuang Chinese cabbage, there are significantly different at p=0.05. Different host-plants have significant effects on larval duration, longevity of adult female, total number of egg production per female and mean egg production per female per day; but they have no significant effects on weight of pupa.
