- aggregation title "Effects of food and temperature on development, fecundity and life-table parameters of Adalia bipunctata (Coleoptera: Coccinellidae)".
- aggregation abstract "Development, reproduction and life tables of Adalia bipunctata (L.) were studied at three temperatures (19, 23 and 27 degrees C) on a mixture of frozen pollen and Ephestia kuehniella Zeller eggs as a factitious food and on the aphids Myzus persicae (Sulzer) and Acyrthosiphon pisum (Harris) as natural foods. Development time of A. bipunctata on all tested diets decreased with increasing temperature. Mortality was lowest at 23 degrees C, averaging 44.5%, 42.6% and 24.3% on factitious food, A. pisum and M. persicae respectively. The shortest developmental time from egg to adult at this temperature was observed on factitious food (18.55 days). However, the factitious food was inferior to the aphid diets in terms of reproduction, yielding the longest pre-oviposition period, shortest oviposition period and lowest fecundity. The mean oviposition rate at 23 degrees C varied from 19.94 to 25.03 eggs day(-1) on factitious food and M. persicae respectively. The intrinsic rate of increase (r(m)) on different foods increased with increasing temperature and ranged from a minimum of 0.08 females/female/day on factitious food (19 degrees C) to a maximum of 0.18 females/female/day on A. pisum (27 degrees C). The results suggest that a mixture of E. kuehniella eggs and pollen fully support development of A. bipunctata larvae and can be used as an alternative to live aphids in the mass rearing of the pre-imaginal stages of the predator. However, reproductive performance of a laboratory population may be better on aphids than on the factitious food.".
