Abstract
Background and Aim: Efficient mosquito vectors are required to persist and propagate arthropod-borne diseases that seriously affect impoverished populations worldwide. Mosquito sensilla plays a crucial role in host-seeking and disease transmission to humans. This study aimed to distinguish between the several types of sensilla found on the antennae and maxillary palps of Culex pipiens and Aedes aegypti, matching this diversity with host preference and disease transmission. Methods: Overall, 1300 mosquitoes were collected and examined using dissection and light microscopy. Scanning electron microscopy was used to identify and describe the diverse types of sensilla found on the antennae and maxillary palps of C. pipiens and A. aegypti. Results: In total, 900 C. pipiens and 400 A. aegypti mosquitoes were identified. The antennae and maxillary palps of C. pipiens and A. aegypti carry both sensilla trichoidea and sensilla chaetica. The C. pipiens antenna has long and short grooved peg sensilla, whereas A. aegypti lacks long pegs and expresses only occasional short pegs. The maxillary palps express Capitate pegs in both mosquito species and exclusively show sensilla campaniform in A. aegypti. Conclusion: The lack of long-grooved pegs and the presence of few short pegs, along with campaniform sensilla, limit the host range of A. aegypti and reduce its susceptibility to many infections, unlike C. pipiens. © Abouelmagd, et al.
