Aedes canadensis (Theobald) were sampled in New Jersey woodland pools over a 3-week period during the spring of 1976 to determine larval distribution. Replicate pools were divided into 3 concentric zones based on depth, and collections were taken with a cylindrical sampler and a standard pint dipper in each zone up to 14" deep. An analysis of variance on the data showed significant differences in distribution of larvae between the 2 sampling techniques. The cylindrical sampler data showed that Ae. canadensis larvae were equally distributed throughout the pools. Dipping collected the most larvae from the shallower zones of the pool and did not adequately sample the larval population in the deeper zones.
