Antennal sensory plaque organs of the Delphacidae (Homoptera: Fulgoroidea)

Abstract

Scanning electron microscopy was used to examine the antennal sensory plaque organs of 104 species in 81 genera of Delphacidae. The plaques have the same external morphology in all examined Delphacidae. Four types of sensory plaque organs are recognized based on the morphology of the denticle, and the evolutionary trends are proposed as Type 1→Type 2→Type 3 and Type 1→Type 2→Type 4. 本文藉由描描弌電子顯微鏡共檢查稻蝨81屬104種之觸角瓦楞感覺器，得知稻蝨科觸角瓦楞感覺器的瓦楞突起外形一致，透過錐狀突起的形態可發現瓦楞感覺器共有四型，它們的進化趨勢推論為第一→二→三型和第一→二→四型
