    Abstract: Experiment shows when the lervae of Apocheima cinerarius are fed with the tender leaves of Populus deltoides Bartr.cv.Lux,"Ⅰ-69/55",and the solutions of five micro-elements,Co,B,Mn,Zn,Ca,are sprayed on the leaves under the following conditions of constant temperature 22±1℃,L:D=18:6 and 55%~59% RH,threr is a significant influence upon not only the survival rate,life circle, body weight and pupation rate,but also the rate and time for the adult emergence after the cold treatment.It takes 14 to 18 d for the larval development, 26 or 22 d shorter than that in the forest.As for the pupal development it only takes 130 to 170 d,much shorter than that of 300 d in the forest.Through using this artificial method,A.cinerarius can be reared generation after generation in the lab in orderto obtain sufficient adults.
