| 摘 要：在實(shí)驗室條件下，采用藥膜法和毒餌法，測定了3種主要的長(cháng)春花堿類(lèi)物質(zhì)長(cháng)春堿、長(cháng)春質(zhì)堿和文多靈對德國小蠊的觸殺和胃毒活性；結果表明，95%長(cháng)春堿TC、98%長(cháng)春質(zhì)堿TC和98%文多靈TC對德國小蠊若蟲(chóng)有較高的觸殺活性，對成蟲(chóng)有較高的胃毒活性，其中95%長(cháng)春堿TC和98%長(cháng)春質(zhì)堿TC的活性高于98%文多靈TC的活性，對德國小蠊若蟲(chóng)的速效性與對照藥劑95%吡蟲(chóng)啉TC相當，處理后48 h達到高峰值，對成蟲(chóng)的速效性低于對照藥劑95%吡蟲(chóng)啉TC，處理后72 h達到高峰值；長(cháng)春堿和長(cháng)春質(zhì)堿在衛生害蟲(chóng)德國小蠊的防治中具有一定的應用價(jià)值。 |

| Abstract：Contact toxicity and stomach poison of vinblastine, vincristine and vindoline against German cockroach were tested by residual film method and poisoning bait method. The results showed that the vinblastine, vincristine and vindoline had high contact toxicity on German cockroach nymph, and stomach poison on German cockroach adult, the activities of vinblastine and vincristine were higher than vindoline. The contact toxicity and stomach poison were increased to a maximum after treatment 48 h and 72 h, respectively. Vinblastine and vincristine could be a potential active ingredients for controlling German cockroach. |
