Field collected, first generation female Aedes cantator were shown to produce heterogeneous eggs that exhibit variable hatch in response to serial inundations and cold conditioning in the laboratory. Nearly 85% of the egg batches exhibited some hatch with the first flooding, representing 69.4% of the total overall hatch. However, 56% of the same egg batches displayed further hatch with subsequent floodings and 34% showed partial hatch before and after cold conditioning. The significance of these findings is discussed in relation to the biology of Ae. cantator.
