Abstract: The laboratory experiment results showed that the mite, Schizotetranychus nanjingensis, could not survive below-10 °C and above 41 °C. Its optimum temperature for it was 20～25 °C. It had very high survival rate at 2 °C.The survive, development and reproduction of the mite varied with photoperiod. The development could not complete in darkness, but the eclosion of eggs was normal. The highest survival rate from egg to adult mite was in a photoperiod of ≥12 h. The shortest period (13 91 d) from young mite to adult female mite was in a photoperiod of 8 h and the longest period (32 33 d) was in 5 h.In the photoperiod of 8 h,≥12 h, the female mite could oviposit normally and the quantity of eggs were 9 13 and 12 67,respectively.The adult female could not oviposit and had the shortest longevity (10 d) in a photoperiod of 5 h.
