二化螟水稻、茭白种群幼虫口器和触角及其感器扫描电镜观察
Mouthparts and Antenna and Their Associated Sensilla of Rice and Water-oat Populations of the Striped Rice Borer(Chilo suppressalis)
摘要
Abstract
[Objective]In order to explore the ultramorphology in antennae and mouthparts and associated sensilla (especially the types, number and distribution) in different populations ofChilo suppressalis Walker, the two organs and their sensilla at different developmental stages were investigated.[Method]The antennae and mouthparts and associated sensilla of rice and water-oat populations ofC. suppressalis were used as materials. We observed the organs with a scanning electron microscopy.[Result]The antennae, mouthparts and their associated sensilla varied with larval stage within populations. The two populations ofC. suppressalis possessed the following characters: the pedicel was typically equipped with three sensilla basiconica and two sensilla chaetica; six pairs of sensilla chaetica were found on the labrum; the mandible bore sevenincisor cusps distally, and carried two sensilla chaetica basally on its outer face; the cardo and stipes each possessed a sensillum chaeticum distally; three sensilla basiconica, two sensilla chaetica and two sensilla styloconica were observed on the galea; a sensillum digitiformium laterally was found on each maxillary palpus; and sensillum chaeticum were observed on the distal of each labial palpus.Difference in sensillum number of flagellum and maxillary palpus between the two populations were as follows: flagellum of the water-oat population was equipped with a sensillum styloconicum and two sensilla basiconica, while the rice population possessed a sensillum styloconicum and a sensilla basiconica; maxillary palpus of the former was equipped with rive sensilla basiconica and three cylindrical sensilla, whereas four sensilla basiconica and four cylindrical sensilla were carried in the latter. Some sensilla chaetica (located at the pedicel, cardo, stipes), sensilla basiconica (distributed at the pedicel, maxillary palpus and galea), sensilla styloconica (distributed at the flagellum and galea) of water-oat population were significantly longer than those of the rice population; whereas some cylindrical sensilla (located at the maxillary palpus) of 1st- to 5th-instar larvae, and sensilla chaetica (distributed at the galea) of 3rd- to 5th-instar larvae were significantly shorter than those of the rice population.关键词
