Antennal Sensilla of Chilo infuscatellus under Scanning Electronic Microscope

Antennae morphology and sensillum types of adult Chilo infuscatellus were studied. Under a scanning electron microscope, 5 distinctive types of antennal sensilla, including sensilla trichodae, sensilla chaetica, sensilla coeloconica, sensilla auriculate and Böhm bristles, were observed in the male and female insects. Except for sensilla auricilla, there were no significant differences on the sensilla between male and female adults.
