  • Cacopsylla chinensis is a monophagous sucking pest on pear trees. The authors of this paper investigated the population dynamics of C.chinensison Pyrus bretschneideri in Yuncheng, Shanxi from 2018 to 2019. The results showed that the number of C. chinensis eggs had two peaks, appearing from early to mid-May and from late June to early July. C. chinensis nymphs peaked from mid-April to late April and from early to mid-June.The hibernation period of the overwintering adults ended from early March to mid-March, and the first generation of adults occurred from early May to mid-May.Taking the characteristics of C. chinensis into consideration, a control strategy of "twice control and one prevention" is proposed, which provides a guiding basis for the integrated insect management in pear orchards.

  • Received Date: 28/09/2021

Abstract: Cacopsylla chinensis is a monophagous sucking pest on pear trees. The authors of this paper investigated the population dynamics of C.chinensison Pyrus bretschneideri in Yuncheng, Shanxi from 2018 to 2019. The results showed that the number of C. chinensis eggs had two peaks, appearing from early to mid-May and from late June to early July. C. chinensis nymphs peaked from mid-April to late April and from early to mid-June.The hibernation period of the overwintering adults ended from early March to mid-March, and the first generation of adults occurred from early May to mid-May.Taking the characteristics of C. chinensis into consideration, a control strategy of "twice control and one prevention" is proposed, which provides a guiding basis for the integrated insect management in pear orchards.
