Abstract
Eggs of the snow-pool mosquito are conditioned to hatch by a sequence of temperatures simulating those of field conditions. The longer eggs are exposed to mean monthly summer temperature (24° C), up to 120 days before exposure to winter temperatures (4°), the greater the percentage of hatch following exposure to cold. For each lot exposed to 24°, hatching was further enhanced by exposure to 4° up to 90 days. The principal effect of exposure to cold was to prolong the period of hatching after the eggs were again exposed to 24°. No eggs hatched which had not experienced a cold period.Keywords
