| Abstract: | The developmental threshold temperature(DTT) and effective accumulated temperature(EAT) of the larvae and whole larval stage and whole generation of Acyrthosiphon pisum were determined under 80% relative humidity and 6 temperature treatments(12 ℃,15 ℃,18 ℃,21 ℃,24 ℃ and 27 ℃).The DTT of each instar larvae from 1st to 4th instar and whole larval stage were 7.309 1 ℃,3.776 6 ℃,3.852 7 ℃,5.256 4 ℃ and 4.874 3 ℃ respectively,and their EAT were 22.974 6,30.652 8,28.207 0,39.273 0 and 125.848 7 degree-day respectively. |
