The parasitoid Amitus fuscipennis MacGown and Nebeker (Hymenoptera: Platygasteridae) is being evaluated as a potential biological control agent of Trialeurodes vaporariorum (Westwood) (Homoptera: Aleyrodidae) on bean crops in Colombia. Partial life history data of this natural enemy is presented here. The development and longevity of adult parasitoids were compared under different temperature and relative humidity combinations. The intrinsic rate of increase of A. fuscipennis was obtained at different climatic conditions on two different bean cultivars using T. vaporariorum as host. Based on our results, A. fuscipennis is considered a good candidate for biological control of the greenhouse whitefly because a) its intrinsic rate of increase is higher than the intrinsic rate of increase of T. vaporariorum at hillside and lowland climatic conditions, and b) it has a broad altitudinal distribution but very dry conditions and high temperature diminish its longevity
