云南甘蔗蓟马种类研究

Studies on Sugarcane Thrips in Yunnan Province

甘蔗是云南主要的经济作物之一,蓟马类是甘蔗的重要害虫,以成虫和若虫集中在甘蔗未展开的心叶内危害,影响甘蔗产量。本研究调查云南省陇川、元江等17个甘蔗种植县、市,共采集成虫标本1 142头。经鉴定,得出害虫种类9种,即蔗腹齿蓟马(又称甘蔗蓟马)(Fulm ekiola serratus)、竹直鬃蓟马(Stenchaeto-thrips bum busae)、黄蓟马(Thrips flavus)、褐蓟马(Thrips fusca)、黄胸蓟马(Thrips hawaiiensis)、花蓟马(Frankliniella intonsa)、禾蓟马(Frankliniella tenuicornis)、玉米黄呆蓟马(Anaphothrips obscurus)和华简管蓟马(Haplothrips chinensis);天敌1种,即横纹蓟马(Aeolothrips fasciatus)。蔗腹齿蓟马(F.serratus)是所有甘蔗种植区的绝对优势种,在所调查甘蔗种植区均有,占所采集鉴定蓟马总数的80.21%。

Sugarcane on Sugarcane, which is one of the economic crops of Yunnan Province. Thrips is the important pests damaged the young leaf and resulted in yield loss. Thrips was collected from sug- arcane planted areas, including 15 counties and 2 city of Yunnan Province, such as Longchuan County, Yuanjiang County, etc. The 1 142 adults specimens were collected, representing 10 species, 9 of which were phytophagous, inluding Fulmekiola serratus, Stenchaetothrips bumbusae, Thrips flavus, Thrips fusca, Thrips hawaiiensis, Frankliniella intonsa, Frankliniella tenuicornis, Anaphothrips obscurus, Haplothrips chinensis, and 1 predatory Aeolothrips fasciatus. Fulmekiola serratus was the dominant species, representing 80.21% of all specimens, and was also the most widely distributed species, being found at all sites.
