摘　　要：大猿叶虫Colaphellus bowringi Baly卵的颜色有浅黄色和深红色2种类型。调查卵的颜色与其后代滞育的发生和繁殖力的关系,结果表明,在25℃、28℃,不同光周期L∶D(11∶13,12∶12,13∶11和15∶9)下,浅黄色卵和深红色卵的后代滞育率没有显著差异;但在L14∶D10下,浅黄色卵的后代滞育率(25℃为58.6%;28℃为33.9%)显著高于深色卵的后代(25℃为45.4%;28℃为11.2%)。卵的颜色与其后代成虫的产卵前期和成虫寿命没有显著相关,但浅黄色卵后代的平均产卵量和平均日产卵量(1663粒和58.6粒)均显著高于深红色卵的后代(1176粒和45.1粒)。Two kinds of color, buff and crimson, were shown in eggs of the cabbage beetle Colaphellus bowringi Baly. In the present study, incidence of diapause and fecundity of progeny in relation to egg color were investigated. At 25℃ and 28℃, no significant difference on the incidence of diapause was found between buff and crimson eggs under different photoperiods of L：D（ 11 ： 13, 12 ： 12, 13 ： 11 and 15 ： 9 ）. However, at L ： D14 ： 10 the incidence of diapauseof progeny from buff eggs （58.6% at 25℃; 33.9% at 28℃） was significantly higher than that from crimson eggs （45.4% at 25℃; 11.2% at 28℃）. There was no significant difference on the pre-reproductive period and adult longevity between the progeny from huff and crimson egg. However, the mean total egg production and mean daily egg production per female of the progeny from buff egg （1663 egg and 58.6 egg） were significantly higher than that from crimson egg（1176 egg and 45.1 egg）.
