摘    要:为明确棕榈蓟马成虫在日光温室的分布特征,2011—2012年,在山东省济南市采用植株调查和蓝板诱集方法研究了其成虫在日光温室菜椒上的种群动态和空间分布。结果表明,自4月中旬,棕榈蓟马种群数量逐渐上升,6月中旬达种群高峰,平均虫量最高6.02头/花。蓝板对棕榈蓟马成虫的诱集量7:00~15:00逐渐增多,13:00~15:00是活动高峰,平均诱集数量占全天的29.42%,之后逐渐减少。空间上,棕榈蓟马成虫数量由西向东逐渐减少,平均诱集数量比例从21.58%逐渐减少到6.93%;由南向北逐渐增加,南边、中间、北边蓝板诱集数量比例分别为21.48%、27.30%和51.22%;垂直方向上,在菜椒植株上部的棕榈蓟马成虫数量(76.58%)显著高于中部(21.77%)和下部(1.65%)。因此,日光温室棕榈蓟马防治的关键期是4月中旬,关键位置为日光温室西部、北部菜椒,喷药时间以早上或傍晚为宜。

关 键 词:棕榈蓟马  种群动态  空间分布  日光温室

Abstract:The population dynamics and spatial distribution of Thrips palmi karny in greenhouses were investigated by inspecting the number of adults on flowers and blue sticky board trapping on sweet pepper in Jinan, Shandong Province from 2011 to 2012. The results showed that the population of T.palmi did not increase steadily until April and reached the peak in mid-June, with a maximum number of T.palmi adults of 6.02 per flower. The number of T.palmi adults on blue sticky traps gradually increased from 7:00 to 15:00, and the number of adults trapped during 13:00-15:00 accounted for 29.42% of the whole day and then gradually decreased from 15:00 to 19:00. In latitudinal direction, the number of T.palmi adults in solar greenhouses gradually decreased from west to east and the average percentages of trapped number were from 21.58% to 6.93%. Meanwhile, the number of T.palmi adults gradually increased from south to north and the average percentages of trapped number were 21.48% for south, 27.30% for middle and 51.22% for north, respectively. On the sweet pepper, the number of T.palmi adults in upper part (76.58%) was significantly higher than that in the middle part (21.77%) and the lower part (1.65%). Therefore, it was recommended to apply pesticides in the early morning or late afternoon of mid-April to control T.palmi, especially in the west and north of the solar greenhouses.
Keywords:Thrips palmi  population dynamics  spatial distribution  solar greenhouse
