Abstract

Prepupae of the subtropical multivoltine bee, M, flavipes, were collected during late summer and stored for 270 days at 4°, 6°, 8°, 10° or 12°C, then incubated at 24°, 25.5°, 27°, 28.5°, 30° or 31.5° until the major or 'first-stock' emergence occurred. Mortality was highest (11-19%) at a storage temperature of 4° or 6°, lowest (5-7%) at 10° or 12° and intermediate at 8°. The main effect of incubation temperature was on the emergence pattern; exposure to one of the three highest temperatures generally led to a shorter mean incubation period and a smaller spread in the dates of emergence. The smallest spread (17 days) occurred at 28.5°, For management of M. flavipes for alfalfa pollination, storage at 8° followed by incubation at 28.5° was best, resulting in a moderate degree of mortality, a high percentage of individuals in the first-stock emergence, and a minimum spread in emergence dates.
