摘要
在成虫期有补充营养条件下，幼期取食棉叶、棉铃和人工饲料个体的平均单雌产卵量分别为565．2、1005．8和1052．2粒；成虫期无补充营养，则单雌产卵量依次为162．2、400．6和1035．6粒。幼期营养较差者产卵前期显著增加、产卵期和寿命明显缩短，幼期营养较好者则影响不大。这种现象表明：棉铃虫成虫期补充营养是幼虫期营养的延续，幼虫期营养较差者需获得补充营养完成生殖活动，若幼虫期营养较好，则成虫无补充营养也能保持较高的繁殖力。
On the condition of complementary nutrition at the adult stage, the average egg numbers oviposited by one female of cotton bollworm which fed cotton leaf, cotton boll and artificial diet at. larval stage were 565.2, 1005.8and 1052.2, respectively. If no complementary nutrition, the eggs were 162.2, 400.6 and 1035.6, respectively, and the ovarian development of the moth was significantly delayed with shortening of reproduchon duration and lifespan of the moths in the individuals pessessed poor nutrition condition at larval stage.It is suggested that the adult nutrition is the soccession of larval nutrition.as the larval food quality is good, the complementary nutrition is not necessary for the adult to mainnin its high fecundity.
