Egg raft adhesion and chorion structure in Culex pipiens L (Diptera: Culicidae).
([dagger]) Originated from egg rafts collected in Iowa in 2002 and colonized at the Iowa State University Medical Entomology Laboratory.
Field collected Aedes albopictus and Culex eggs were hatched, and first instar larvae were placed in twenty-five containers in the field into which wild adult Culex were allowed to freely oviposit egg rafts. Five replicates of each of the five larval density treatments were established: high Aedes albopictus, low Aedes albopictus, high Culex, low Culex, and a control containing no larvae.
The species is also dispersed through the drifting of egg rafts. Total dispersal time from embryonic development through larval and juvenile stages can extend to several months until benthic recruitment occurs.
