摘要
<正>用浓度为 ５００ ｍｇ／ｋｇ灭幼脲（ＤＦＢ）处理的构树枝条喂养桑天牛成虫，测定桑天牛每天取食量、虫粪量，不同时间对桑天半成虫每天虫粪、血淋巴及所产的卵中天幼脲含量进行ＨＰＬＣ检测。结果表明，桑天牛成虫每天摄入的天幼脲中，大部分排出体外且结构不变，雌、雄成虫排出量占摄入量分别为80．７４％及７６．４８％；灭幼脲在桑天牛成虫体内还有累积作用，连续饲喂以ＤＦＢ处理的枝条，10ｄ后桑天牛成虫血淋巴中ＤＦＢ含量高达雌虫１９．５４９×10－6ｇ／头，雄虫 １７． ８２３ × １０－6 ｇ／头；而雌成虫每天摄入ＤＦＢ量的 １． ３９％转移到卵中。
Abstract
Caged adults Apriona germari (Hope) were fed with Diflubenzuron(DFB) treated Broussonetia papyrifera (L. ) branch bark. The amount of DFB ingestion, DFB in feces, offspring eggs, adult hemolymph were measured or detected with HPLC. The results show that 80. 74% and 76. 48% of ingested DFB passed through the body everyday without being absorbed in female and male adult of Apriona germari, respectively; DFB retained in hemolymph got peak in 10 days after continues being fed with DFB coated branch bark, the concentrations of DFB in hemolymph were 19. 549 × 10-6 g(per female), 17. 823 × 10-6 g(per male)； Of the DFB ingested by female,about 1. 39% were transferred to the offspring eggs.
