Summary The African malaria mosquito Anopheles gambiae exhibits a strong innate sensory drive to seek out human scent. To detect odorants, An. uses olfactory neurons (OSNs) that can be divided into different classes by unique repertoires of chemoreceptor gene expression. We applied CRISPR-Cas9-mediated T2A-In Frame Fusions and the QF2/QUAS system gain genetic access specific OSN subsets in expressing genes Ir25a , Ir76b Gr22 orco . first optimized methods generate cell-type QF2 driver QUAS responder lines map expression patterns these chemoreceptors across appendages. next transcuticular calcium imaging record neurophysiological responses select human-related odorants for each class. This neurogenetic toolkit tiling including those responsive CO 2 stands support systematic efforts decode olfaction this prolific disease vector at high-resolution combat malaria.

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