Abstract: The biology and influence of temperature on the development of nymphal stages of Euborellia annulipes (Lucas) was studied in growth chambers at 15, 20, 23, 25, 28, 30, 33, and 35°C, 60 + 10% RH, and 14L:10D photoperiod. The viability of eggs ranged from 72.5% (20°C) to 89.3% (28°C). Temperatures of 15° and 35°C were lethal to eggs. The egg incubation period ranged from 6.9 days (33°C) to 18.7 days (20°C). The number of instars of E. annulipes tended to decrease with the increase of temperature. However, in most cases, the nymphal stage presented five instars. Survival of nymphal stage and overall survival (from egg to adult emergence) were higher at 28°C (96.0 and 85.7%), and lower at 30°C (66.0 and 51.6%). Developmental times from egg to adult emergences of males and females with five instars ranged from 51.5 days (33°C) to 171.3 days (20°C) and from 48.7 days (30°C) to 161.8 days (20°C), respectively.
