Sexually Dimorphic Visual Processing in the Yellow-Fever Mosquito, Aedes aegypti

This study investigates sexually dimorphic visual processing in Aedes aegypti mosquitoes, finding that females pursue moving targets while males suppress approach behavior despite similar biomechanical capabilities.

DNA barcoding and olfactory identification of attractive nectar sources for Aedes aegypti mosquitoes

This study identifies plant taxa and volatile compounds attractive to Aedes aegypti mosquitoes using DNA barcoding, behavioral assays, and volatile profiling.

Neuron synchronization analyzed through spatial-temporal attention

This paper introduces a spatial-temporal attention normalizing flow to model neuron synchronization in the insect antennal lobe, revealing interactions between cell types and odorant mixture dynamics.

Spectral preferences of mosquitos are altered by odors

This study shows that mosquito spectral preferences change based on olfactory stimuli, with host odors broadening and floral/oviposition odors narrowing their preference to green wavelengths.

Molecular logic of pheromone recognition enables rational design of insect behavior modulators

This paper decodes the structural logic of pheromone recognition in silkmoths to design small molecules that disrupt insect mating behavior.

Olfactory preferences and chemical differences of fruit scents for Aedes aegypti mosquitoes

This study investigates how fruit scent chemistry influences Aedes aegypti mosquito attraction, finding that compound proportions, not just presence, determine scent attractiveness.

Multisensory integration in Anopheles mosquito swarms: The role of visual and acoustic information in mate tracking and collision avoidance

This study shows that Anopheles mosquitoes use both visual and acoustic cues to navigate swarms, track mates, and avoid collisions.

Effect of temperature on mosquito olfaction

This study examines how environmental temperature affects the olfactory responses of Aedes aegypti mosquitoes to host and plant odors.

The olfactory gating of visual preferences to human skin and colors in mosquitoes

This study shows that mosquito attraction to specific hues is influenced by odor, with CO2 enhancing preference for orange and red wavelengths associated with human skin.

Aedes aegypti vision-guided target recognition requires two redundant rhodopsins

This study shows that Aedes aegypti mosquitoes require two redundant rhodopsins for vision-guided target recognition, as single mutations of op1 or op2 do not impair CO2-induced target seeking.

The olfactory basis of orchid pollination by mosquitoes

This paper shows that mosquitoes pollinate an orchid through scent-based attraction and neural processing in their antennal lobe, revealing the ecological and neural mechanisms behind nectar-feeding behavior.

Neuromodulation and Differential Learning Across Mosquito Species

The paper investigates odor learning and dopaminergic innervation differences across mosquito species, finding species-specific learning patterns and innervation in the antennal lobe.

Visual-olfactory integration in the human disease vector mosquito, Aedes aegypti

This study investigates how olfactory and visual cues are integrated in mosquitoes, showing CO2 modulates visual responses and revealing asymmetrical, time-dependent neural coupling between these senses.

Live calcium imaging of Aedes aegypti neuronal tissues reveals differential importance of chemosensory systems for life-history-specific foraging strategies

The paper uses live calcium imaging in Ae. aegypti larvae to study sensorimotor responses and foraging strategies, revealing the role of chemosensory systems.

Geosmin attracts Aedes aegypti mosquitoes to oviposition sites

This study shows geosmin attracts Aedes aegypti mosquitoes to oviposition sites and can be used as bait, with beetroot peel extract as a cost-effective alternative.

Modulation of host learning in Aedes aegypti mosquitoes

This study shows that aversive olfactory learning influences mosquito host preference, with dopamine playing a key role in modulating olfactory responses.
