Abstract
Matings were made between [female][female] raised at 30[degree]C and [male][male] raised at 36[degree], 30[degree], and 20[degree]C. More biparental offspring appeared from crosses of dtf reared at 30[degree] than from crosses with [male][male] reared at other temps. A greater percentage of biparental [male][male] was produced from crosses with [male][male] of 30[degree]. Differential fertilization is offered as the chief cause of the noted variations.
