The distribution of Aedes sollicitans (Walker) and Ae. taeniorhynchus (Wiedemann) eggs on 3-yr-old diked dredge spoil disposal areas in coastal North Carolina was monitored from March through September, 1976. The eggs were extracted by sieving and flotation from soil samples (15 x 15 x 2 cm) collected every 1-3 weeks from each of 4 major habitats (bare mud, new Aster, old Aster and shrub) on each of 4 disposal areas. Overall, most (ca. 90%) of the eggs found were those of Ae. taeniorhynchus. However,10% of the eggs from March to September and 26% in late September were those of Ae. sollicitans. Although the distribution of mosquito eggs among the major habitats varied among the disposal sites, the overall order of habitats based on eggs densities on all sites was (least to most): bare mud, shrub, old Aster and new Aster. The majority of eggs found were in surface root mats of the new Aster zone. Soil cracks contained medium densities of eggs in all habitats and most of the eggs were on the top 10 cm of the crack walls. Very few eggs were found on soils which were covered by a thin algal film. Egg density throughout the season was related to fluctuations in rainfall and standing water level.
