Melanism in insects: a review

  • Online:2008-01-30 Published:2008-01-04

摘要:

昆虫黑化是自然界中普遍存在的一种多型现象,也成为揭示物种在自然界中进化与适应的经典范例。昆虫黑化形成的原因与类别多种多样,黑化的遗传调控和分子基础也各不相同。本文根据国外黑化昆虫研究取得的主要进展,结合我国东方粘虫Mythimna separata种群中发生的黑化现象,对昆虫黑化的形成原因、类别、遗传调控、生物学变异以及黑化的分子基础等方面研究现状进行了概述,并对该领域的未来研究热点进行探讨。

关键词: 昆虫, 黑化, 遗传调控, 生物学变异, 分子基础

Abstract: Insect melanism is one of the common polymorphism in nature, and has become classical study system for species evolution and adaptability. The causes, controls and biology of insect melanism are significantly different among different insects. Integrating the main research progress in alien melanic insects and the melanic oriental armyworm, this paper reviewed the causes, classifications, genetic controls, biological variations and molecular basis of melanism in insects. Finally, the future hot topics in this research field were suggested.

Key words: Insect, melanism, genetic control, biological variation, molecular basis
