Growth of Ephestia cautella (Walker) population under conditions found in an empty peanut warehouse and response to variations in the distribution of larval food
Environmental Entomology 13 (1), 171-174
Abstract: When empty peanut warehouse conditions were simulated, spreading a constant amount of food among additional locations did not significantly affect the number of eggs laid by Ephestia cautella (Walker), but did reduce the number of larvae that completed development. Population growth decreased from roughly 7- to 3-fold as the number of locations increased from 1 to 24. The mean number of eggs laid at a location was proportional to the number of peanuts at that location. Larval production declined mainly as a result of females laying eggs at a smaller fraction of locations as the number of locations increased.
