A biochemical key was applied in order to study transmission of malaria and Bancroftian filariasis in Anopheles gambiae sensu stricto, An. arabiensis and An. merus in different localities in north-eastern Tanzania. The technique was found to be a useful additional taxonomic tool for field entomologists. Significant differences between species in the rate of infection with Bancroftian filariasis were obtained between An. gambiae s.s. and An. funestus (P less than 0.005) and between An. funestus and An. arabiensis (P less than 0.0001). There were also significant differences between most of the investigated localities in the rate of filarial infection. However, there were no significant differences between the three species or between localities with respect to malaria sporozoite rates. Possible reasons for the observed variation between species and localities with respect to vectorial activity for Bancroftian filariasis are discussed.
为了研究冈比亚按蚊指名亚种、阿拉伯按蚊和梅氏按蚊在坦桑尼亚东北部不同地区传播疟疾和班氏丝虫病的情况，应用了一种生化方法。该技术被证明是野外昆虫学家一种有用的额外分类工具。在班氏丝虫病感染率方面，冈比亚按蚊指名亚种和嗜人按蚊之间（P小于0.005）以及嗜人按蚊和阿拉伯按蚊之间（P小于0.0001）存在显著差异。在大多数调查地区，丝虫感染率也存在显著差异。然而，在疟原虫子孢子率方面，这三个物种之间或各地区之间没有显著差异。文中讨论了观察到的班氏丝虫病媒介活性在物种和地区间存在差异的可能原因。
