通过扫描电子显微镜对1979年的瓜苏锥蝽若虫和1998年的朱尔贝锥蝽若虫的摩擦沟、颊和喙进行比较研究(半翅目,猎蝽科)

Comparative study of the stridulatory sulcus, buccula and rostrum of the nymphs of Triatoma guazu Lent & Wygodzinsky, 1979 and Triatoma jurbergi Carcavallo, Galvão & Lent, 1998 by scanning electron microscopy (Hemiptera, Reduviidae).

Abstract

The ultrastructural morphology of the ventral region of the head (rostrum and buccula) and proesternum (stridulatory sulcus) of nymphs from the 1st to 5th instars of Triatoma guazu Lent & Wygodzinsky, 1979 and Triatoma jurbergi Carcavallo, Galvão & Lent, 1998 was described. Morphological differences between the two species and of the five nymphal stages development of each species were observed. These structures showed systematic differential characteristics of the studied species and may be used to increase their taxonomic range.

摘要

描述了1979年的瓜苏锥猎蝽(Triatoma guazu Lent & Wygodzinsky)和1998年的朱尔贝锥猎蝽(Triatoma jurbergi Carcavallo, Galvão & Lent)一至五龄若虫头部腹侧区域(喙和颊)及前胸(摩擦沟)的超微结构形态。观察到了这两个物种之间以及每个物种五个若虫发育阶段的形态差异。这些结构显示了所研究物种的系统差异特征,可用于扩大其分类范围。
