Research of parasitoids of Sphaerolecanium prunastri fonscolombe in the western Tianshan wild fruit forest
[Objective]The aim of this study is to identify the parasitoids resources of the important inva-sive species Sphaerolecanium prunastri Fonscolombe in the wild fruit forests of the Western Tianshan Mountains in Xinjiang in the hope of providing an important basis for the subsequent control of this invasive pest using n-ative parasitoids.[Methods]In this study,parasitic enemies of S.prunastri were obtained by laboratory rea-ring of field-collected hosts and were classified using morphological and DNA barcoding methods.[Results]A total of 7 parasitoids were obtained,among which 3 species(Discodes coccophagus Ratzeburg,Microterys hortulanus Erdös,and Aprostocetus trjapitzini Kostjukov)were new records for China.Additionally,this study provided the barcode sequences of the 28S rDNA and COI genes of the 7 parasitoids and their Genebank acces-sion numbers.[Conclusion]The Pachyneuron solitarium(Hartig)is the dominant parasitoid on Prunus divar-icata Ldb.,and M.hortulanus is the dominant parasitoid on Armeniaca vulgaris Lamarck.
