摘要：

Density-dependent development in the pitcher plant mosquito, Wyeomyia smithii (Coquillett), indicates variation in competitive ability both within and between populations. We tested 2 disparate populations of W. smithii for 3 types of interference competition: chemical and encounter competition and cannibalism We found no significant effects of any of these interference mechanisms or variation in food consumption within or between populations. We suggest that asymmetric competition in W. smithii is more likely the result of differences in assimilation or use of assimilated resources than to larval interference or differential ability to consume food.
