Molecular Basis of CO Sensing in .

Carbon dioxide (CO) released by plants can serve as a cue for regulating insect behaviors. is a widely distributed forestry pest that may use CO as a cue for foraging and oviposition. However, the molecular mechanism underlying its ability to sense CO has not been elucidated.

The dual coding of a single sex pheromone receptor in Asian honeybee Apis cerana.

In Asian honeybees, virgin queens typically only mate during a single nuptial flight before founding a colony. This behavior is controlled by the queen-released mandibular pheromone (QMP). 9-oxo-(E)-2-decenoic acid (9-ODA), a key QMP component, acts as sex pheromone and attracts drones.

Odorant Receptors Expressing and Antennal Lobes Architecture Are Linked to Caste Dimorphism in Asian Honeybee, (Hymenoptera: Apidae).

Insects heavily rely on the olfactory system for food, mating, and predator evasion. However, the caste-related olfactory differences in , a eusocial insect, remain unclear. To explore the peripheral and primary center of the olfactory system link to the caste dimorphism in , transcriptome and immunohistochemistry studies on the odorant receptors (ORs) and architecture of antennal lobes (ALs) were performed on different castes.
