Abstract
The duration of immature stages and adult longevity of the two aphid
parasitoids Dlaeretialla rapae and Aphidius sp < /em>.were studied at different temperatures
and food supply. The results indicated that the incubation period of eggs, larval, and
pupal durations of the parasitoid D. rapae were significantly affected by different host
species. The total developmental period of this parasitoid averaged 16.07 days when
reared on Brev/coryne brassicae while it was 11.93 days when reared on Aphis
craccivora .The total developmental period of Aphidlus sp < /em>.reared on Sitobion avenae
showed an average of 13.85days. The results also indicated that the average
longevity of the two parasitolds were decreased linearly with the increase of
temperature. The mean longevity of adult parasitoids was prolonged when they were
supplied daily with 10% sugar solution.
