Distribution and ultrastructure of sensillae on legs and anal cerci in earwig Anisolabis maritima (Dermaptera: Carcinophoridae)

Chemoreceptors play an important role for insects behavior in detecting their defined targets for feeding or mating. This study revealed the presence of different forms of receptors sensillae occurred on the legs and anal cerci of Anisolabis maritima using SEM. Leg surface contains three types of trichoid, one type basiconica sensillae. Generally, sensillae distribution is fewer on the femur than tibia and tarsus. Anal cerci also contained three types of trichoid, three types of basiconic, one type of coeloconica sensillae, and campaniform sensillae on the terminal end of females only.
