Acoustic communication plays an important role during the courtship of many mosquito species. Male mosquitoes show strong attraction to female wing beat frequencies, mediated via spectral matching between frequency and male ear mechanical tuning frequency. Such acoustic typically occurs within swarms, male-dominated aggregations with species-specific properties. Despite hundreds relevant publications being available, lack a central platform hosting all associated data hinders research efforts limits cross-species comparisons. Here, we introduce MACSFeD (Mosquito Communication Swarming Features Database), interactive for exploration our comprehensive database containing 251 unique reports focusing on different aspects communication, including hearing function, phonotaxis, as well swarming parameters. serves easily accessible, efficient, robust visualization tool research.

Mosquito transient receptor potential ankyrin 1 (TRPA1) channels are nociceptors that can be activated by noxious heat and/or chemicals (e.g., electrophiles). When activated, TRPA1 typically trigger avoidance behaviors. Previous studies have found mosquito play important roles in host-seeking, preferred temperature selection, and of the environment. Accordingly, considered valuable biochemical targets for developing repellents antifeedants. However, it is presently unknown whether activation impacts their chemical agonists repel mosquitoes, such as catnip oil citronellal. To address this gap knowledge, we heterologously expressed Aedes aegypti (AaTRPA1) Xenopus laevis oocytes evaluated its electrophysiological responses to presence or absence a stimulus. We when AaTRPA1 was exhibited dampened either Subsequent airborne repellency bioassays with adult female Ae. revealed mosquitoes were less repelled citronellal exposed an increase ambient exceeded threshold (i.e., >32 °C); contrast, DEET (a non-TRPA1 agonist) unaffected. Our results suggest TRPA1-agonizing may offer protection from temperatures exceed thermal channels. This implications choice used during extreme events, which becoming more common because global climate change.

Aedes aegypti mosquitoes are the principal vectors of dengue and continue to pose a threat human health, with ongoing urbanization, climate change trade all impacting distribution abundance this species. Hot periods becoming increasingly common their impacts on insect mortality have been well established, but they may even greater fertility. In study, we investigated high temperatures Ae. fertility both within across generations. Mosquitoes developing under elevated exhibited higher critical thermal maxima (CTmax), reflecting developmental acclimation, declined increasing temperature. females, decreased fecundity while in males it tended decrease proportion eggs that hatched individuals producing viable offspring. Rearing sexes at 35°C increased subsequent generation effects persisted gonotrophic cycles same generation. Moreover, exposure adults further beyond temperature alone. These findings highlight sub-lethal plastic responses stress This has significant implications for predicting mosquito populations thriving warmer environments.

Anopheles coluzzii (Coetzee & Wilkerson) and its sibling species gambiae s.s. (Giles) are highly anthropophilic among the major malaria vectors in sub-Saharan Africa. Mosquitoes use various senses to find hosts, but rely primarily on olfaction. Therefore, mosquito olfactory system has been studied extensively, including a variety of studies comparing chemosensory gene expression between An. zoophilic quadriannulatus (Theobald). These revealed species-specific antennae maxillary palps, which raised question potential role for palps determining host preferences. To answer this question, we mechanically ablated antennae, labella, ran both control mosquitoes through dual-port olfactometer. While aimed identify organs responsible vertebrate choice, exclusively responded human odor, so were unable do so. However, able refine our understanding roles these host-seeking activation (leaving release cage) as well odor response (entering an port). As expected, most important behaviors: was roughly halved abolished antennae-ablated mosquitoes. Maxillary palp ablation had little impact activation, reduced similar degree exclusion CO2. Finally, while labellar dramatically (probably associated with inability feed), it response, suggesting that any choice is likely not olfactory.

In insects, response olfactory system to developmental might be mediated by body size or mass because and are negatively affected most ectotherms.

However, is controversial and needs be demonstrated. The goal this study was behaviorally characterize non-contact three common pyrethroids control: permethrin, deltamethrin an ⍺-cypermethrin.
