摘要：

【目的】南美斑潜蝇Liriomyza huidobrensis为我国重要的入侵害虫，我们于2017年7月首次发现其已扩散至西藏。本研究旨在了解西藏地区南美斑潜蝇的发生现状及其寄生蜂种类。【方法】2017和2018年6月上旬-9月中旬对西藏拉萨、林芝、山南和日喀则4个地区的南美斑潜蝇的发生危害及其寄生蜂组成进行了调查采样。【结果】调查的西藏这4个地区均发现南美斑潜蝇分布和危害；温室发生时间为6月上旬-9月中旬，而露地的发生高峰在7月下旬-8月上旬。其寄主植物有9科21种，主要有豆科(Fabaceae)、茄科(Solanaceae)和伞形科(Umbelliferae)等，主要嗜好经济作物有豇豆Vigna unguiculata, 扁豆Lablab purpureus , 莴笋Lactuca sativa var. angustana和白菜Brassica rapa ssp. pekinensis。其寄生蜂包括姬小蜂科(Eulophidae)、茧蜂科(Braconidae)和瘿蜂科(Cynipidae)共计3科9属16种，分别为双斑潜蝇姬小蜂Diglyphus bimaculatus, 豌豆潜蝇姬小蜂Diglyphus isaea, 小斑潜蝇姬小蜂Diglyphus minoeus, 万氏潜蝇姬小蜂Diglyphus wani, Diglyphus sp., 纵纹瑟姬小蜂Cirrospilus vittatus, Hemiptarsenus sp., 芙新姬小蜂Neochrysocharis formosa, 底比斯姬小蜂Chrysocharis pentheus, 普金姬小蜂Chrysocharis pubicornis, Chrysocharis sp., 潜蝇柄腹姬小蜂Pediobius metallicus, Pnigalio sp., 西伯利亚离颚茧蜂Dacnusa sibirica, Dacnusa sp.和Gronotoma sp.；其中优势种为西伯利亚离颚茧蜂、双斑潜蝇姬小蜂和豌豆潜蝇姬小蜂，其个体数量占比分别为总采集个体数的48.7%, 22.1%和12.9%。【结论】西藏南美斑潜蝇的寄生蜂种类丰富，发挥着重要的自然控制作用。建议进一步加强优势寄生蜂生物学、控害潜力评价以及利用研究，为南美斑潜蝇的绿色防控提供指导。

Abstract: 【Aim】 Liriomyza huidobrensis is an important invasive pest in China. It was firstly found in Tibet in July, 2017. This study aims to confirm the occurrence status of L. huidobrensis and its parasitoids in Tibet. 【Methods】 The occurrence and damage of L. huidobrensis and its parasitoids were investigated in four regions, Lhasa, Nyingchi, Lhoka and Shigatse, in Tibet from early June to mid-September in 2017 and 2018. 【Results】 The results revealed that L. huidobrensis has already colonized and caused damage in all the four regions surveyed in Tibet from early June to mid-September in 2017 and 2018. The population occurred from early June to mid-September in green house and the peak of occurrence in the field was from late July to early August. Twenty-one species of host plants were reported to be damaged by L. huidobrensis and they belong to nine families, mainly Fabaceae, Solanaceae and Umbelliferae. L. huidobrensis caused the most serious damage to such economic crops as Vigna unguiculata, Lablab purpureus, Lactuca sativa var. angustana and Brassica rapa ssp. pekinensis. Sixteen species of parasitoids including Diglyphus bimaculatus, Diglyphus isaea, Diglyphus minoeus, Diglyphus wani, Diglyphus sp., Cirrospilus vittatus, Hemiptarsenus sp., Neochrysocharis formosa, Chrysocharis pentheus, Chrysocharis pubicornis, Chrysocharis sp., Pediobius metallicus, Pnigalio sp., Dacnusa sibirica, Dacnusa sp., and Gronotoma sp. were recorded, and they belong to nine genera of three families (Eulophidae, Braconidae and Cynipidae). Da. sibirica, Di. bimaculatus and Di. isaea were identified as the dominant species and their individuals accounted for 48.7%, 22.1% and 12.9% of the total individuals collected, respectively. 【Conclusion】 The parasitoid species of L. huidobrensis are quite rich in Tibet, and these parasitoid species show strong natural control effect. It is suggested that the study of biology, control potential and utilization of dominant parasitoids should be strengthened in the future for the prevention and control of the invasive L. huidobrensis.
