Reproductive potential and development of rose leafhopper, Edwardsiana rosae (L.) (Homoptera Cicadellidae), at constant temperatures on apple
Journal of Entomological Science 31 (4), 427-431
Abstract: Reproductive potential and developmental rates for rose leafhopper, Edwardsiana rosae (L.), were determined in a constant-temperature study at 13, 17, 23, and 30°C. Developmental rate was faster at progressively higher temperatures, except at 30°C, where there was no egg hatch. Developmental rate was faster for males than for females at each temperature. Regression equations yielded an estimate of 7°C as the temperature threshold for development. The largest number of progeny was produced at the lowest temperature, and survival decreased with increasing temperature. Body length and head capsule width of the five nymphal instars and adult stages of rose leafhopper did not vary among temperatures or between male and female.
