| 豌豆彩潜蝇Chromatomyia horticola是我国重要的潜叶蝇类蔬菜害虫, 寄生蜂是其重要的天敌?2018年7月, 豌豆彩潜蝇首次在西藏地区被发现?为探明西藏地区豌豆彩潜蝇的发生情况及其天敌寄生蜂种类, 于2018年-2019年对西藏拉萨?林芝?山南?日喀则4个地区进行了调查采样?结果表明, 豌豆彩潜蝇在西藏地区发生程度中等, 为害等级达Ⅲ级?JP+1〗调查到被其为害的寄主植物为5科7属7种, 主要嗜好菊科和豆科植物?豌豆彩潜蝇的寄生蜂种类包括3科8属12种, 其中优势种为豌豆潜蝇姬小蜂Diglyphus isaea?双斑潜蝇姬小蜂Diglyphus bimaculatus和西伯利亚离颚茧蜂Dacnusa sibirica, 分别占总羽化寄生蜂个体数的35.71%?28.18%和21.01%, 豌豆潜蝇姬小蜂主要来自寄主植物豌豆, 双斑潜蝇姬小蜂和西伯利亚离颚茧蜂的发生期最长, 7月-9月均有发生?同期, 我们在西藏调查发现了入侵种南美斑潜蝇Liriomyza huidobrensis, 为此, 本文还讨论了西藏地区豌豆彩潜蝇和南美斑潜蝇的寄生蜂种类组成差异和寄生蜂的控害特性及控害效应, 以期为制定生态调控和绿色防控策略提供指导? |
| 英文摘要: |
| Chromatomyia horticola (Goureau) is an important vegetable pest, and parasitoids are important bio-control agents for agromyzid leafminer. In July 2018, C.horticola was firstly recorded in Tibet. Here, C.horticola and its parasitoid species in Lhasa, Linzhi, Shannan and Shigatse were investigated in 2018 and 2019. The results showed that C.horticola had a moderate occurrence with a damage degree of Ⅲ. Seven plants that belonged to five families as host of C.horticola were recorded, in which Asteraceae and Fabaceae were the main families. The parasitoid complex, dominated by the family Eulophidae, consisted of 12 species, of which Diglyphus isaea, D.bimaculatus, and Dacnusa sibirica were dominant species and their individuals accounted for 35.71%, 28.18% and 21.01% of the total individuals. D. isaea was mainly from the host plant Pisum sativum. D. bimaculatus and D.sibirica had the longest occurrence period from July to September. Contemporaneously, the invasive Liriomyza huidobrensis was also recorded. For comparison, the composition of parasitoids between C.horticola and L.huidobrensis in Tibet were discussed, providing future guidance for formulating ecological and green-prevention strategies. |
