近几年,我们在开展棉红铃虫Pectinophoragossypiella(Saunders)综合防治研究的过程中,发现第一代红铃虫形成虫花后,除一部分幼虫留在虫花内化蛹外,相当数量的幼虫不知去向。查阅有关资料,多数记载第一代红铃虫幼虫老熟后一般留在虫花内化蛹;少数资料介绍,主要留在虫花内化蛹,少量也可入土化蛹。为此,我们从1981年开始,对第一代红铃虫幼虫化蛹习性作了初步观察。
In recent years, we conducted a comprehensive study on the prevention and control of Pectinophora gossypiella (Saunders) in cotton bollworm and found that after the first-generation pink bollworm was formed, all but a few of the larvae remained inside the pupae, I do not know where to go. Access to relevant information, the majority of records of the first generation of pink bollworm larvae generally stay in the pest internalization of pupae; a few data, the main stay in the pest internalization pupa, a small amount can also be embedded in pupation. To this end, we started from 1981, the first generation of pink bollworm larvae pupation made preliminary observations.
