大多数昆虫都感染了可遗传的兼性共生体。这种共生体首先出现在宿主谱系中，是从其他宿主物种横向转移的结果。虽然一些兼性共生体是生殖寄生物，因此对宿主核基因的传递产生不利影响，但越来越多的证据表明，许多兼性共生体对宿主有益，例如，保护宿主免受天敌的侵害。这种共生体的起源、传播和维持与通过有益的核突变进行的适应性进化过程有许多相似之处，也有重要的不同之处。时机已经成熟，发展一个连贯的理论的'群体遗传学'的有益遗传共生体。
Most species of insects are infected with heritable, facultative symbionts. Such symbionts first appear within a host lineage as a result of lateral transfer from other host species. Although some facultative symbionts are reproductive parasites and thus adversely affect the transmission of host nuclear genes, there is growing evidence that many are beneficial to their hosts by, for example, conferring protection from natural enemies. The origin, spread, and maintenance of such symbionts bears many similarities to, as well as important differences from, the process of adaptive evolution by beneficial nuclear mutations. The time is ripe for the development of a coherent theory of the 'population genetics' of beneficial heritable symbionts.
