摘要:

【目的】调查研究林果害虫朝鲜球坚蚧Didesmococcus koreanus Borchsenius的寄生性天敌昆虫资源,描述形态,确认优势寄生蜂,为朝鲜球坚蚧的生物防治提供基础数据。【方法】采集朝鲜球坚蚧成虫于室内饲养获得寄生性天敌,在体视显微镜下进行物种鉴定及描述;室内饲养寄生蜂,比较不同寄生蜂的寿命及性比。【结果】室内饲养朝鲜球坚蚧成虫,获得4种寄生蜂,分别为球蚧跳小蜂Encyrtus infidus Rossi、球蚧花角跳小蜂Blastothrix sericea Dalman、赖食蚧蚜小蜂Coccophagus lycimnia Walker和松毛虫楔缘金小蜂Pachyneuron solitarium Hartig。4种寄生蜂的占比分别为65.14%、21.14%、13.14%、0.57%。球蚧跳小蜂和球蚧花角跳小蜂数量较多,为朝鲜球坚蚧优势寄生蜂,雌雄比分别为1.33∶1、1.31∶1。球蚧跳小蜂雌性最长能活18 d,雄性最长能活9 d;球蚧花角跳小蜂雌雄最长寿命均为17 d。【结论】朝鲜球坚蚧寄生蜂资源丰富,记录4种,其中球蚧跳小蜂和球蚧花角跳小蜂为其优势寄生蜂,雌雄比均为1.3∶1,并且2种优势寄生蜂雌性寿命无明显差异。

Abstract:

【Objective】 To investigate the parasitic natural enemy insect resources of Didesmococcus koreanus Borchsenius, a fruit pest in forest and describe their morphology and screen out the dominant parasitic wasps in the hope of providing theoretical basis for biological control of Didesmococcus koreanus Borchsenius in the future.【Methods】 Adults of scale insect were collected and reared indoors to obtain parasitoid natural enemies.Afterwards, these parasitoids were identified and described.Parasitic wasps were raised indoors to record the lifespan of parasitic wasps and compare the lifespan of different parasitic wasps.【Results】 It was found that there were four parasitic wasps of Didesmococcus koreanus Borchsenius: Encyrtus infidus Rossi, Blastothrix sericea Dalman, Coccophagus lycimnia Walker and Pachyneuron solitarium Hartig.These species accounted for 65.14%, 21.14%, 13.14% and 0.57% of the parasitoids, respectively.The number of Encyrtusinfidus Rossi and Blastothrix sericea Dalman were large, and they were the dominant parasitic wasps of Didesmococcus koreanus Borchsenius, with female and male ratios of 1.33∶1 and 1.31∶1, respectively.The maximal lifespan of Encyrtus infidus Rossi fmales was 18 days and that of males was 9 days; the maximal lifespan of Blastothrixsericea Dalman both sexes was 17 days.【Conclusion】 There are abundant resources of parasitic wasps of Didesmococcus koreanus Borchsenius.In this study, 4 species are recorded, among which Encyrtus infidus Rossi and Blastothrix sericea Dalman were the dominant parasitic wasps.the sex ratio of the two dominant parasitic wasps was 1.3∶1, and there is no significant difference in female lifespan between the two dominant parasitic wasps.
