根据流行病学证据，在南佛罗里达、加勒比地区和中美洲，斑库蠓可能是蓝舌病病毒（BTV）的生物媒介。在实验室中，利用田间捕获的昆虫进行了一系列实验，评估了该物种对BTV的传播潜力。虽然在任何一次捕获中取食的蝇的百分比有很大的变化，但证明了C。在以血液和病毒的混合物为食后，insignis被感染。感染率为20 ~ 62.5%。胸内接种后，BTV在C insignis中复制到高滴度。这些苍蝇也被证明能够将BTV传播给易感的绵羊和含胚鸡蛋。这一系列的实验首次提供了明确的证据，证明C insignis是蓝舌病病毒的生物载体。这是第一个被证实的BTV在新热带的载体。
Based upon epidemiological evidence, Culicoides insignis Lutz is a probable biological vector of bluetongue viruses (BTV) in South Florida, the Caribbean Region and Central America. The vector potential of this species for BTV was evaluated in the laboratory in a series of experiments using insects caught in the field. Although there was great variation in the percentage of flies that fed from any one catch, it was demonstrated that C. insignis became infected after membrane feeding on a mixture of blood and virus. The infection rates ranged from 20 to 62.5%. Following intrathoracic inoculation, BTV replicated to high titres in C insignis. Such flies were also shown to be capable of transmitting BTV to susceptible sheep and embryonated chicken eggs. This series of experiments provides the first conclusive evidence that C insignis is a biological vector of bluetongue virus. This is the first proven vector of BTV in the neotropics.
