Effects of temperature on the survival and development of the Morrill lace bug (Heteroptera: Tingidae) on guayule
Environmental Entomology 14 (3), 329-331
Abstract: The rate of development of Corythucha morrilli Osborn and Drake was measured at seven temperatures on guayule, Parthenium argentatum Gray. At 60% RH and 16-h light cycle the time required for development from egg to adult ranged from 34.7 days at 20°C to 17.3 days at 30°C. Little nymphal development occurred at 17.8°C, and no eggs or nymphs developed at temperatures exceeding 34.4°C. Egg and nymphal survival were greatest at the median temperatures.
