✦ Synopsis

Larvae of Cerura vinula L. were raised at 18, 25 and 30°C in order to test the effect of temperature on the speed of the entire larval development. The time required decreases hyperbolically, with increasing temperature. The optimum temperature seems to be 25°C since all larvae raised at this temperature developed completely. In contrast, some of the larvae at 18 and at 30°C were unable to molt from instar 2 to instar 3, causing high loss of larvae. Further development and metamorphosis were normal. At 30°C, some of the larvae died before the pupal molt; the remaining larvae showed morphological deficiencies upon pupal molt.
