【目的】 本文通过测定杀蟑胶饵对德国小蠊Blattella germanica (L.)和美洲大蠊Periplaneta americana (L.)的致死效果，以及德国小蠊对杀虫剂氟虫腈的抗性，从而为胶饵选择和蟑螂的化学防治提供参考。【方法】 用饲喂法在实验室测定了7种国产杀蟑胶饵及5种美国产杀蟑胶饵或毒饵站对德国小蠊的致死效果，5种国产蟑螂胶饵对美洲大蠊的致死效果，以及对5种国产蟑螂胶饵陈化1个月后对德国小蠊的致死效果。并采用点滴法测定了两个德国小蠊野外品系对氟虫腈的抗性。【结果】 7种中国产胶饵中，5种对德国小蠊抗性和非抗性品系在第7 天的校正死亡率高于91%。其中韩世和克贝特对德国小蠊的药效显著慢于绿叶、宏宇洁和优士。绿叶、宏宇洁和优士对美洲大蠊在第7天的校正死亡率均高于89%。陈化1个月后的胶饵只有克贝特对蟑螂的致死率有较大降低。美国产胶饵或毒饵站对德国小蠊的致死率均大于82%。点滴法抗性测定结果显示德国小蠊的两个野外品系（Cincy，Irvington）对氟虫腈生理抗性指数分别是4.3和115.1。【结论】 不同胶饵对德国小蠊和美洲大蠊的致死效果有明显差异。尽管德国小蠊Irvington品系对氟虫腈表现为高抗性，含0.05%氟虫腈的胶饵仍然对它有效。 insecticide resistance, gel bait, insecticide

Abstract  [Objectives]  To compare the efficacy of commonly used cockroach bait products in the U.S. and China and thereby help consumers and pest management professionals select the most effective baits for cockroach management. [Methods]  We evaluated the efficacy of 7 common cockroach gel baits from China, and 5 cockroach gel baits, or bait stations, from the U.S., against the German cockroach (Blattella germanica (L.)) and the American cockroach (Periplaneta americana (L.)), under laboratory conditions. In addition, we conducted topical assays to evaluate the level of resistance of two field strains of the German cockroach to fipronil. [Results]  Five of the 7 Chinese gel baits achieved ≥ 91% corrected mortality of German cockroaches (both resistant and non-resistant strains) after 7 d. Hanshi and Kebeite gel baits acted much slower than Green Leaf, Hongyujie, and Youshi. The latter three products achieved ≥ 89% mortality of American cockroaches after 7 d. One month old Kebeite baits produced lower mortality than fresh baits among German cockroaches. All five baits from the U.S. caused ≥ 82% mortality in German cockroaches after 7 d. The resistance ratio of the two field strains of German cockroaches to fipronil were 4.3 and 115.1, respectively. [Conclusion]  There are significant differences in the efficacy of different baits against the German cockroach and the American cockroach. Although one strain of German cockroach showed high resistance to fipronil, two gel baits containing 0.05% fipronil still achieved 100% mortality in this strain in the laboratory.
