Abstract
Observations on the biology of Acinopterus angulatus Lawson and Aceratagallia curvata Oman were made in the greenhouse between June 1964 and March 1965 at Mesa, Arizona. For angulatus, the period from egg to adult averaged 41.5 days. The production of nymphs averaged 224.3 for once-mated females and 188.1 for multiple-mated females. The greatest number of nymphs produced by a female was 621. Longevity of once-mated females averaged 68.2 days, but females caged continuously with a male lived an average of only 45.2 days. For curvata, the period from egg to adult averaged 31.5 days. The production of nymphs averaged 64.1. The greatest number of nymphs produced by a female was 113. Longevity of females averaged 107.7 days; that of males averaged 121.4. Measurements were made of eggs, nymphal instars, and adults of both species.
