Flanders, S.E. 1945b The bisexuality of uniparental Hymenoptera, a function of the environment.. American Naturalist 79: 122-141.

Notes: With the uniparental chalcid Habrolepis rouxi, the production of unisexual or bisexual broods may depend on the environmental conditions to which the parent females are subjected during their early larval stages. Females that develop at temperatures of 80 degrees F. or less, in healthy mature red scale, Aonidiella aurantii (Mask.), infesting freshly picked grapefruit are thelyotokous, producing only unisexual (female) broods. The chalcid Prospaltella perniciosi is bisexual when reproducing on San Jose scale growing on peach trees and unisexual when reproducing on San Jose scale growing on the cow melon (Citrullus vulgaris) in the lab.
