摘要
棉铃虫幼虫的消化道粗短,成虫的消化道细长;预蛹期消化道则收缩;蛹期则是幼虫消化系统解体、成虫消化系统形成的一个过渡期;成虫消化系统的基本构造在蛹期第5d形成。
The digestive tube of Heliocoverpa armigera larvae is short and wide, while that of adult is long and thin. digestive tube begins to shrink in pre-pupa stage, then in pupa stage,the old one in larvare is disintegrated and the new one of adult is integrated. The embryonic form of digestive system in adult is formed at 5-day-old pupa.
