摘要
通过田间调查与室内观察相结合的方法,测定不同色板对甘蔗蓟马的诱集效果,并对甘蔗蓟马进行种类、发生特点、田间种群数量变动情况的调查。结果表明:甘蔗蓟马发生期在4月下旬,5月份种群数量开始逐渐增长,6月下旬达到高峰期,7月份以后开始逐渐减少;采集获得标本1124头,经鉴定甘蔗蓟马有两种,分别是蔗蓟马和华简管蓟马,蔗蓟马是优势种,占所采集甘蔗蓟马总量的99.64%;而在色板诱集方面,蓝色粘虫板诱集甘蔗蓟马的效果显著高于其他几种颜色。
Sugarcane thrips are important pests of sugarcane,which damage the young leaf and result in yield loss seriously.Through field investigation and laboratory observation,the attractiveness effect of different coloured sticky on sugarcane thrips was tested,and the kinds of sugarcane thrips,the characteristics and the population dynamic of sugarcane thrips in field were carried out.The results showed that sugarcane thrips occured in late April,population began to increase in May,reached its peak in late June and began to decrease in July.The 1124 adult specimens were collected,belonging to 2 species,Fulmekiola serratus and Haplothrips chinensis.F.serratus was the dominant species,with 99.64% of all specimens.The results of coloured sticky attractiveness showed that the attractiveness of blue colour,was significantly larger than others.
