Abstract: The mosquito’s feeding behavior influences its efficiency to transmit and complete an arbovirus’ life cycle. With a bite, a mosquito could either get infected or transmit the deadly dengue virus. The impact of dengue infection on biting behavior has yet to be clearly elucidated. There has been no consensus as to whether dengue infection affects the biting behavior of mosquitoes. Some groups have reported that dengue infection reduces the mosquito’s feeding efficiency and causes them to bite more whilst others reported no significant changes in its feeding efficiency. To study the mosquito’s biting in depth, we designed a high-resolution close-up video recording and computerized behavior analysis assay. This assay was used to determine the impact of DENV infection on the mosquito’s biting behavior on an anesthetized mouse. Our results showed that infected mosquitos were faster in approaching the mouse, have reduced probing efficiency, with more counts of unsuccessful probes and longer probing time. Our findings support that dengue infection modulates behavior in the mosquito to enhance its transmission.
