Beauveria bassiana (Balsamo) Vuillemin (isolate CG306) was tested on 3rd instars of 9 Triatoma spp., 4 Rhodnius spp., 2 Panstrongylus spp. and Dipetalogaster maxima (Uhler) at 25 degrees C and 50% RH. Quantitative sporulation of the fungus on cadavers was studied at 25 degrees C and 97% RH. Mortality, estimates of survival time, and conidial production on cadavers differed significantly among the genera and species tested. Panstrongylus herreri Wygodzinsky, Dipetalogaster maxima, Triatoma picturata Usinger, Rhodnius robustus Larrousse, Rhodnius prolixus Stål, Triatoma infestans (Klug), and Triatoma brasiliensis Neiva were most susceptible to fungal infection. Most conidia per cadaver were produced on Triatoma williami Galvão, Souza & Lima and Triatoma lecticularia (Stål). Results indicate that B. bassiana (CG306) might be a candidate for control of important or potential vectors of Trypanosoma cruzi using the fungus as a bioinsecticide.
在25摄氏度和50%相对湿度条件下，对9种锥蝽属、4种红猎蝽属、2种强喙蝽属昆虫的三龄若虫以及大吮蝽（Dipetalogaster maxima (Uhler)）进行了球孢白僵菌（Beauveria bassiana (Balsamo) Vuillemin，分离株CG306）的测试。在25摄氏度和97%相对湿度条件下研究了真菌在虫体上的定量产孢情况。在所测试的属和种中，死亡率、存活时间估计值以及虫体上的分生孢子产量存在显著差异。赫氏强喙蝽（Panstrongylus herreri Wygodzinsky）、大吮蝽、花斑锥蝽（Triatoma picturata Usinger）、粗壮红猎蝽（Rhodnius robustus Larrousse）、红带锥蝽（Rhodnius prolixus Stål）、骚扰锥蝽（Triatoma infestans (Klug)）和巴西锥蝽（Triatoma brasiliensis Neiva）对真菌感染最为敏感。每个虫体产生分生孢子最多的是威廉锥蝽（Triatoma williami Galvão, Souza & Lima）和小板锥蝽（Triatoma lecticularia (Stål)）。结果表明，球孢白僵菌（CG306）可能是一种利用真菌作为生物杀虫剂来控制克氏锥虫重要或潜在传播媒介的候选生物。
