摘要:

目的:比较微红纤恙螨和地里纤恙螨这两种近缘螨种的形态学差异。方法:从已经鉴定确认的微红纤恙螨和地里纤恙
螨的幼虫标本中,选择结构清晰的100只标本,在显微镜下观察和测量其形态结构,对比分析两种近缘恙螨的形态学差异。所
比较的两种恙螨的幼虫标本均采自黄胸鼠体表。结果:微红纤恙螨的背板近似正方形且SB<AP,地里纤恙螨的背板近似长方
形且SB>AP,两者间差异均有统计学意义(P<0.01)。地里纤恙螨的SD、SB值范围较宽,其SD、SD宽/长、SB、PSB、PW/AP、PW
均值都略大于微红纤恙螨(P<0.05)。结论:两种恙螨形态差别很小,微红纤恙螨的SB<AP,地里纤恙螨的SB>AP,以此可鉴别
这两种近缘螨种。

Abstract:

Objective: To compare the morphological characteristics of two sibling species of chigger mites: Leptotrombidium
rubellum and Leptotrombidium deliense. Methods: 100 identified larvae of two mite species(L. rubellum and L. deliense)with clear
structure were collected from the body surface of Asian house rat, Rattus tanezumi(R. flavipectus), whose morphological structure were
observed and measured under a microscope for analyzing the morphological difference between two sibling species. Results: L.
rubellum had a quadrate-like scutum(SB<AP), but L. deliense had a rectangle-like scutum(SB>AP), and the difference between
them had statistical significance(P<0.01). The SD, SB range of L. deliense is rather wider, and its SD, SD width/length, SB, PSB,
PW/AP, PW value were all slightly higher than L. Rubellum(P<0.05). Conclusion: The two mite species are very close to each other
morphologically with tiny differences. Compared with SB<AP in L. rubellum, the difference of L. deliense is SB>AP, and this difference
can be used as the key evidence to differentiate the two mite species.
