Insect vectors are organisms that transmit pathogens from one host to another through their bites or feeding activities. These vectors play a crucial role in the transmission of various diseases, including malaria, dengue fever, Zika virus, and Lyme disease. Understanding the biology, behavior, and ecology of insect vectors is essential for developing effective strategies to control and prevent the spread of these diseases. Research in this area often focuses on studying the interactions between pathogens, vectors, and hosts, as well as developing vector control measures and vaccines to reduce the burden of vector-borne diseases.
