我们研究了Papatasi（Scopoli）、Duboscqi（Neveu-Lemarie）、Sergenti（Parrot）和Sergentomyia schwetzi（Adler，Theodor，& Parrot）传播裂谷热（RVF）病毒的潜力。After.以接种裂谷热病毒的仓鼠为食。papatasi、S. sergenti和S. schwetzi被感染并发展为播散性感染。所有接种裂谷热病毒的帕帕塔斯和杜博斯奇都发生了高滴度感染。而接种S. schwetzi含有可检测的病毒，并且感染个体含有的病毒显著少于两种白蛉属物种。虽然50%的杜氏原螯虾将裂谷热病毒传播给仓鼠，但只有14%的帕帕塔斯原螯虾和没有一只斯氏原螯虾传播该病毒。需要进一步研究以确定白蛉作为裂谷热病毒载体的作用。
We examined the potential for Phlebotomus papatasi (Scopoli), Phlebotomus duboscqi (Neveu-Lemarie), Phlebotomus sergenti (Parrot), and Sergentomyia schwetzi (Adler, Theodor, & Parrot) to transmit Rift Valley fever (RVF) virus. After. feeding on hamsters that had been inoculated with RVF virus. P. papatasi, P. sergenti, and S. schwetzi became infected and developed disseminated infections. All P, papatasi and P, duboscqi inoculated with RVF virus developed high-titer infections. In contrast, only 41% of the inoculated S. schwetzi contained detectable virus, and infected individuals contained significantly less virus than the two Phlebotomus species. Although 50% of the inoculated P. duboscqi transmitted RVF virus to hamsters, only 14% of P. papatasi and none of the S, schwetzi transmitted this virus. Additional studies are needed to determine the role of sand flies as vectors of RVF virus.
