摘要
目的探索S-烯虫乙酯对德国小蠊的现场控制效果。方法选择2个农贸市场作为研究对象,实验组使用S-烯虫乙酯药片贴进行德国小蠊控制,对照组使用商家自行购药控制德国小蠊密度。通过比较2个市场的德国小蠊密度变化和发育繁殖情况,评估S-烯虫乙酯对德国小蠊的控制效果。结果实验组在投药30 d后德国小蠊总密度下降明显,密度下降率达到67.11%,若虫密度下降率为79.79%。对照组前60 d总密度变化不大,第90天开始密度上升。统计分析结果表明,实验组与对照组在第90和120天的德国小蠊密度存在显著差异。施药现场带回的德国小蠊若虫中,外形畸形组死亡较早。施药现场带回的10个卵鞘中有3个未孵化,7个卵鞘产生的122只若虫成功羽化40只成虫,其中3个成虫翅膀出现畸形。结论S-烯虫乙酯通过致畸和不育作用,能够减小德国小蠊种群密度,降低其繁殖能力。
Objective A field trial was conducted to explore the efficacy of S-methoprene for controlling German cockroaches.Methods Two farmer's markets in Shanghai City were randomly selected as locations for conducting our research.The experimental market was administered S-methoprene adhesive tablets while the control group was subjected to traditional control methods.To evaluate the efficacy of each strategy against German cockroaches,German cockroach population densities and reproduction rates between the two markets were compared.Results After 30 days of treatment,the density of German cockroaches in the experimental group declined significantly(67.11%reduction rate overall,79.79%in nymphs).In the control group,the density of German cockroaches remained relatively stable for the first 60 d,then started to increase from day 90 th.Among the German cockroaches brought back from the treatment site,nymphs deformed and died earlier.Three of the 10 egg cases collected from the control treatment sites could not hatch,while the remaining seven eggs eventually produced a total of 122 nymphs.Among these,40 nymphs successfully molted into adults;however,three of them deformed with bad wings.Conclusion Experimental findings indicate that S-methoprene can effectively reduce the population density and fecundities of German cockroaches through its teratogenic and sterilizing effects.
