Vegetation management for constructed treatment wetlands often involves knocking down emergentvegetation with heavy equipment and inundating the dead vegetation after a period of drying. Such practicescreate favorable conditions foi larval mosquitoes. We studied the relationship between length of the dryingperiod for an emergent macrophyte, Typha sp., and the abundance of aquatic inveftebrates in replicated 0.18-m3, wading pools. The mosquiio, Culex tarsalis, was significantly more abundant in pools containing vegetationaged for 2 wk before inundation compared to pools containing vegetation aged 5 wk, freshly cut vegetation, orwithout vegetation. Potential larval mosquito food resources (particles between 2 and 61 um in equivalentspherical di-ameter) in the 2-wk aging treatment did not differ significantly from the other treatments during the5-wk experiment. The abundance of other larval culicids, nonculicine Diptera, and potential mosquito predators (i.e., Dyiiscidae and Aeshnidae) did not differ significantly among the vegetation aging treatments.
