The lacewing eggs and cocoons were treated under 10, 12, 14, 16, 18 ℃ temperature for two days and five days, the hatching rate decreased compared with the control , which were 18.3%, 6.0%, 5.0%, 1.7%, 0.3% and 70.0%, 52.0%, 18.3%, 9.0%, 4.0%, respectively. However, after 90 days the unhatched lacewing eggs were treated at 10 ℃/10 days. When the temperature was lower, with the increase in the number of days, the emergence rate was reduced. After the low temperature treating cocoon for two-days, the emergence rates of the low temperature compared with the control were decreased by 6.8-0.2%. The emergence rates of the low temperature compared with the control were decreased by 27.7-18.5% and 29.3-19.3%. The better emergence rate of cocoon was under to two-day treatment. If the temperature was lower with the increase in the number of days, the emergence rate was also reduced. The instar larvae was treated at 10 ℃/ two-day and four-day, the survival rate was still more than 85%. However, treated larvae was at 18 ℃/four-day, that the survival rate significantly decreased to 43.3%, 24.2%, 19.2%. If the temperature was higher, and the increase in the number of days, the survival rate was reduced. Lacewing larvae and adults were starvated, the larger of larval has more resistant to starvation, while adult survival rate in the first two days was significantly reduced.

Lacewing eggs uniformly dispersed in the paper shredding, rice husk, sawdust, vermiculite, etc. inside paper tube with different materials under one-day refrigerated, the use of shredding and vermiculite was compared with the control decreased hatchability ( plain paper tube ) by 0.8% and 34.2%, respectively. The use of rice husk and sawdust was compared with the control increased by 0.6% and 10.4%, and the lacewing eggs without refrigeration were reduced. After two-day refrigerated, the lacewing eggs were placed in vermiculite that have hatchability only 8.7%. Lacewing eggs in cold storage treatment of different materials with cut wood was better. However, after lacewing eggs were treated at 5 ℃/two-day, reduced significanty hatchability. After lacewing adult was treated at 5 ℃/one-day to six-day, the survival and fecundity was compared with the control were decreased . If the temperature was lower with increasing in the number of days, adult survival and fecundity was reduced.
