摘要:

【目的】研究新疆西天山野果林外来入侵物种杏鬃球蚧Sphaerolecanium prunastri Fonscolombe的寄生蜂资源,为利用本土寄生蜂防治该外来入侵害虫提供重要依据。【方法】野外采集寄主并进行室内饲养,获得杏鬃球蚧寄生性天敌,并运用形态学、DNA条形码鉴定物种。【结果】共获得寄生蜂7种,其中中国新记录3种(食蚧点刻跳小蜂Discodes coccophagus Ratzeburg、园囿花翅跳小蜂Microterys hortulanus Erdös、提亚长尾啮姬小峰Aprostocetus trjapitzini Kostjukov),同时提供了7种寄生蜂的28S rDNA及COI基因序列及其Genebank登录号。【结论】松毛虫楔缘金小蜂Pachyneuron solitarium (Hartig)为野樱桃李Prunus divaricata Ldb上的优势寄生蜂,园囿花翅跳小蜂为野杏树Armeniaca vulgaris Lamarck上的优势寄生蜂。

Abstract:

【Objective】 The aim of this study is to identify the parasitoids resources of the important invasive 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 native parasitoids.【Methods】 In this study, parasitic enemies of S. prunastri were obtained by laboratory rearing 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 accession numbers.【Conclusion】 The Pachyneuron solitarium (Hartig) is the dominant parasitoid on Prunus divaricata Ldb., and M. hortulanus is the dominant parasitoid on Armeniaca vulgaris Lamarck.
