The effect of temperature on the development and survival of two populations of Aedes campestris Dyar and Knab (Diptera: Culicidae)
Larvae of A. campestris from Saskatoon, Saskatchewan, and Churchill, Manitoba, were reared at constant temperatures of 15, 20, 23, 25, and 27 °C. Larvae of both populations failed to complete their development to adults at 15 °C, although development to third- and fourth-instar larvae did occur and...

Summary: | Larvae of A. campestris from Saskatoon, Saskatchewan, and Churchill, Manitoba, were reared at constant temperatures of 15, 20, 23, 25, and 27 °C. Larvae of both populations failed to complete their development to adults at 15 °C, although development to third- and fourth-instar larvae did occur and survival at this temperature was greatest in the population from Saskatoon. The optimum developmental temperature for both populations was found to be 23 °C. The development rate and the survival rate was higher in the Churchill population at temperatures above 20 °C. At 15 °C, contrary to what would be expected, survival of larvae was much greater in the more southern (Saskatoon) population. |
