Abstract: Yellow-spined bamboo locust Ceracris kiangsu is an important bamboo pest in South China. To better understand the physiological and biochemical mechanisms of the pest ‘urine puddling’ behavior, scanning electron microscopy was employed to examine the type, number, external morphology, and distribution ofC. kiangsu adults antennal sensilla, and the differences in these aspects between male and female adults were compared. The antennae of male and female C. kiangsu were filiform in shape, and consisted of 1 scape, 1 pedicel, and 23 flagellomeres. The length and width of the antennae were similar between the males and females (P>0.05). Six types of sensilla were recorded for the males and females, including sensilla trichodea Ⅰ, sensilla trichodea Ⅱ, sensilla chaetica, sensilla basiconica Ⅰ, sensilla basiconica Ⅱ, and sensilla coeloconica. The sensilla basiconica had the largest number, occupying about 53% of the total, and concentrated on the 8th-21st flagellar segments. Both the males and the females had the similar distribution characteristics of each sensilla on the antennae. The total number of the males sensilla was significantly higher than that of the females sensilla (P<0.05), and the males had a significant larger number of sensilla basiconica and sensilla coeloconica, as compared with the females (P<0.05).
