The results show that frequency of food and water replacement for A. chinensis decreased with the decrease of temperature. A. chinensis could develop under low temperature conditions, but the development significantly prolonged with the decrease of temperature. Weight of A. chinensis adults decreased with the decrease of temperature and initial feeding age. The nymphs T2-3 (3 after ‘-’ represents the 3rd instar) were not able to develop to adults, the nymphs T1-3 and T2-4 were able to develop to adults, but most of them had deformed wings. The ecdysone contents on the 5th day after the insects entered the 5th instar were significantly lower in T1-3 and T2-3 (27.37 ng/L and 24.21ng/L) than in CK-3 (30.16 ng/L). The nymphs T1-4, T1-5 and T2-5 were able to develop to adults, and the adults of T1-4 and T1-5 could oviposit (7.04, 10.25) at the temperature. In the T2 groups, only T2-5 and T2-female adult could oviposit (9.2, 17.05) during restored feeding, but the oviposition was significantly lower than that of the CK group (27.26). Females in the T1 groups all could oviposit during restored feeding, and the oviposition in the older instar group was significantly higher than that in the younger instar group. %U http://www.zgswfz.com.cn/EN/10.16409/j.cnki.2095-039x.2020.03.002
