摘　　要：Rhizophagus grandis(Coleoptera: Rhizophagidae) is an important predator of Dendroctonus valens which is an invasive alien pest attacking pine trees in China.It was first introduced into China in 2000 and mass rearing techniques had been developed by the authors since then.This paper dealed with the study on the developmental threshold temperature and the effective accumulated temperature of R.grandis.The result showed that the developmental threshold temperatures of egg,larva and pupae were 3.59±2.92 ℃,1.96±0.73 ℃ and 9.27±1.19 ℃ respectively,and the effective accumulated temperatures were 98.32±16.26 degree-day,296.94±12.45 degree-day and 449.67±53.19 degree-day respectively.Therefore,the total effective accumulated temperature from egg to pupa was 844.93 degree-day.Rhizophagus grandis（Coleoptera： Rhizophagidae） is an important predator of Dendroctonus valens which is an invasive alien pest attacking pine trees in China.It was first introduced into China in 2000 and mass rearing techniques had been developed by the authors since then.This paper dealed with the study on the developmental threshold temperature and the effective accumulated temperature of R.grandis.The result showed that the developmental threshold temperatures of egg,larva and pupae were 3.59±2.92 ℃,1.96±0.73 ℃ and 9.27±1.19 ℃ respectively,and the effective accumulated temperatures were 98.32±16.26 degree-day,296.94±12.45 degree-day and 449.67±53.19 degree-day respectively.Therefore,the total effective accumulated temperature from egg to pupa was 844.93 degree-day.
