Subject(s): In: Journal of Economic Entomology v. 57, no. 3, p. 348-350Summary: Reno, Spartan, and Kentucky I barley; Clintland and Dodge oats; Comanche wheat, and Piper sudan 428-1 (Sorghum vulgare) were tested a t constant temperatures of 45, 55, 65, 75, 85 and 90°F, at a constant light intensity of approximately 1500 ft-c for 16 hr daily. Significant differences were noted in rate of reproduction by each of the biotypes of the corn leaf aphid under different temperatures. Also at each temperature there were differences between biotypes on all hosts except on Spartan barley at 55°F. KS2 survived best on most hosts at high temperature, KS. on most hosts at low temperature.
