The effect of dry and moist heat was quantitated on the probing of Aedes aegypti (L.). The temperatures used ranged from 28 to 12 with 2° increments. Fully satiated, slightly dehydrated, and 18-hr-water-starved mosquitoes were used. The dry heat activated the mosquitoes, but did not induce probing. Moist heat induced probing and 34 was found to be most effective. Water-satiated mosquitoes turned away from temperatures higher than 34° and so did mosquitoes that were denied access to water for a short period. Water starved mosquitoes continued to probe avidly to moist heat up to 42. An attempt is made to explain this difference in behavior.
