Distribution pattern of Glossina fuscipes fuscipes (Diptera: Glossinidae) in Bahr el Jebel State, southern Sudan.

摘要

A survey to establish the distribution of tsetse flies (Diptera: Glossinidae) in southern Sudan was conducted using biconical traps. Only Glossina fuscipes fuscipes was caught.

Glossina f. fuscipes was encountered in gallery forest along water courses with no significant differences in sex ratios and proportions of tenerals and non-tenerals between trap catches (P
