A swine fever epizootic decimated the pig herds in villages within the Yamba focus of human trypanosomiasis. Ecological studies of Glossina palpalis palpalis populations were carried out in one of the villages for four years following the disappearance of the pigs, which had been the principal nutritive host of the Glossina in the area. One important behavioural modification occurred, namely the establishment of a small peridomestic tsetse population. The flies deserted the patches of residual forest to settle around the periphery of the village. This probably occurred in numerous other villages where the epizootic had destroyed the herds of pigs. The modified behaviour has increased the man-fly contact, but, on the other hand, facilitates vector control.
一场猪瘟使人类锥虫病扬巴疫源地内各村的猪群大量死亡。在猪消失后的四年里，对扬巴疫源地内一个村庄的冈比亚按蚊种群进行了生态学研究，猪曾是该地区冈比亚按蚊的主要营养宿主。出现了一个重要的行为变化，即在村庄周边建立了一小群采采蝇。这些苍蝇离开了残留的森林区域，在村庄周边定居下来。在许多其他因猪瘟导致猪群死亡的村庄可能也发生了这种情况。这种行为变化增加了人与苍蝇的接触，但另一方面，也便于进行病媒控制。
