Background
Motivation for the study. Dengue epidemics caused by A. aegypti occur during climatic events in tropical countries such as Peru; however, the feeding behavior of the mosquito usually goes unnoticed. Background: Main findings. A. aegypti populations in Marcavelica and Querecotillo showed anthropophilic feeding behavior during cyclone Yaku and in the 2023 El Niño. However, populations with different feeding patterns are not ruled out. Background: Implications. The PCR-RFLP technique of the blood cell cytochrome B gene could be implemented in vector control policies through an entomo-virological surveillance plan.
