Abstract: 【Aim】 To explore the differences in larval sensilla of Carposinidae with different host range. 【Methods】 The ultramorphology of sensilla on the larval antennae and mouthparts of the monophagous Carposina coreana Kim, which feeds exclusively on fruits of Cornus officinalis Sieb. et Zucc., was investigated by using scanning electron microscopy. 【Results】 The basal scape of the antenna is devoid of sensilla. The pedicel possesses two sensilla chaetica and three sensilla basiconica. The terminal flagellum carries distally one sensillum styloconicum and three sensilla basiconica. Six types of sensilla are found on the mouthparts: sensilla chaetica are abundant and widespread; sensilla styloconica are mainly located on the galeae, maxillary palp and labial palp; sensilla digitiformia are found on the epipharynx and the lateral margin of the distal segments of maxillary palps; sensilla basiconica and sensilla placodea are only located on the maxilla; and epipharyngeal sensilla are only present on the epipharynx. 【Conclusion】 There is no strict correspondence between larval sensilla and host range in Carposinidae.
