Sex specific regulation of the soldier caste ratio in the social parasitoid

与其他的全社会膜翅目昆虫不同，群居类寄生蜂的独特之处在于，它们进化出了包括军人种姓在内的两性社会性。考察了军人种姓比例的作用和调节。两性士兵都有能力抵御异性竞争对手。种姓构成是由基因决定的，而女性则受环境因素的影响。环境调控的机制可能因环境因素的不同而不同。

Unlike other eusocial Hymenoptera, social parasitoids are unique in that they have evolved sociality involving a soldier caste in both sexes. The function and the regulation of the soldier caste ratio were examined. Soldiers of both sexes have ability to defend against heterospecific competitors. The caste composition was genetically determined, while in females it was affected by environmental factors. The mechanism of environmental regulation was likely to be different with different environmental factors.
