Abstract

Cytoplasmic incompatibility (CI) in insects is an intrapopulational sterility phenomenon. Although known for nearly 40 years, it has only recently attracted the attention of evolutionary biologists, having been found in an increasing number of species. Apparently, the proximate cause of CI is the presence of rickettsia-like endocellular microorganisms. An ultimate cause can be identified in the fact that males do not transmit cytoplasmic genes, including those of rickettsia.

摘要

昆虫细胞质不兼容（CI）是一种种群内不育现象。尽管已经存在近 40 年，但直到最近才引起进化生物学家的关注，因为在越来越多的物种中发现了这种现象。显然，CI 的直接原因是存在类似于立克次体的内共生微生物。一个最终原因可以确定，即雄性不传递细胞质基因，包括立克次体基因。
