摘要:

【目的】明确云南省危害芋头的蓟马种类及其对芋头的危害,为其生物学特性研究和综合防治提供基础信息。【方法】2015年6~9月,采用直接采集法对云南省7个州(市)蔬菜基地芋头上的蓟马进行调查,同时观察记录对芋头的危害情况。【结果】从7个州(市)15个地点芋头上采集到1028头蓟马成虫,经鉴定,危害芋头的蓟马隶属于蓟马科(Thripidae)针蓟马亚科(Panchaetothripinae)领针蓟马属(Helionothrips)的安领针蓟马(Helionothrips aino)和木领针蓟马(Helionothrips mube),其中木领针蓟马792头,占采集标本数量的77.04%。分别描述了两种领针蓟马的识别特征及其对芋头的危害。【结论】领针蓟马是芋头上的一类常见害虫,危害芋头的蓟马为安领针蓟马和木领针蓟马,其中木领针蓟马为优势种。

【Objective】The present experiment was conducted to identify thrips species and its damage to taro in Yunnan province, in order to provide basic information for further study on biological characters of thrips and its integrated control. 【Method】Thrips were identified, which were directly collected from taro plants in vegetables bases of 7 prefectures(cities) in Yunnan province from June to September in 2015, meanwhile, the damaged symptoms of taro plants were investigated and recorded. 【Result】A total of 1028 thrips adults were directly collected from 15 taro planting areas of 7 prefectures(cities). The identification result showed that, thrips damaging taro were identified as Helionothrips aino and Helionothrips mube belonging to Helionothrips, Panchaetothripinae, Thripidae, of which, 792 individuals of H. mube were collected, accounting for 77.04% of all collected samples. Then their recognizable morphological characters and damages to taro were described. 【Conclusion】Helionothrips is one of common insect pests on taro, including H. aino and H. mube, and H. mube is dominant species.
