We examined brood sex ratios of an undetermined species of Copidosoma. Most broods (65%) were unisexual, with a greater proportion of female broods. Some mixed broods contained extremely small proportions of wasps of the opposite sex. Our results imply that the female-biased sex rations in this species cannot be explained by local mate competition theory.
我们研究了一种未确定种类的丽蝇蛹集金小蜂的育雏性别比例。大多数育雏（65%）是单性的，雌性育雏的比例更高。一些混合育雏中异性黄蜂的比例极小。我们的结果表明，该物种中偏向雌性的性别比例无法用本地配偶竞争理论来解释。
