有关昆虫发育的激素,目前已知的有脑激素(PTTH)、保幼激素(JH)、蜕皮激素(MH)、滞育激素(DH)和羽化激素(EH)。本世纪七十年代,随着昆虫激素研究的深入,人们发现一些化学物质能引起昆虫的早熟变态,有的并随之产生体色变化和生育障碍。这类化学物质,阻碍了昆虫体内JH正常的合成、释放、运输和接受。虽然此类化学物质并不是昆虫本身分 There are currently known hormones for insect development such as PTTH, JH, ecdysone (DH), and eclampsia (EH). Seventies of this century, with the insemination of hormones in-depth study, people found that some chemicals can cause premature metamorphosis of insects, and some and subsequently produce body color changes and fertility disorders. Such chemicals prevent the normal synthesis, release, transport and acceptance of JH in insects. Although these chemicals are not insects themselves
