【摘要】 为了掌握张掖湿地蓟马群落组成及发生规律,为防治蓟马对湿地植物的危害提供参考。对张掖湿地蓟马种类、主要寄主植物、优势种群及种群消长规律进行了调查。结果表明:张掖湿地蓟马共有11种,分别属于3科6属,即蓟马科Thripidae 4属7种,管蓟马科Phlaeothripidae 1属2种,纹蓟马科Aeolothripidae 1属2种。其中花蓟马Frankliniella intonsa(Trybom)、烟蓟马Thrips tabaci Lindeman和西花蓟马Frankliniella occidentalis(Pergande)为优势种,优势度分别为23.32,20.59,15.67。蓟马种群动态调查结果显示,3月下旬蓟马开始出现,5月中下旬虫口数量开始显著增加,7月中旬至9月下旬为发生高峰期,11月中旬蓟马进入越冬期。更多还原

【Abstract】 In order to understand the community composition and occurrence of thrips,and to provide a control reference of damage to the wetlands plants,thrips species,host-plant species,dominant population and population dynamics were investigated in wetland of Zhangye. Results show that there were 11 species of wetland thrips,belonging to 3 families,6 genera. 7 species of Thripidae belonged to 4 genera; 2 species of Phlaeothripidae were in 1 genera and 2 species of Aeolothripidae were in 1 genera. The dominant species were F. intonsa( Trybom),T. tabaci Lindeman and Frankliniella occidentalis( Pergande),and the dominance degree were 23. 32,20. 59 and 15. 67,respectively. The population dynamics of thrips showed that thrips began to appear in late March. The number of thrips increased significantly in mid-May,which peaked at the highest period from late July to early September,then thrips entered the overwintering period.更多还原
