摘要
蓟马是为害云南葡萄的一种主要昆虫,特别在早熟葡萄产区发生较重,造成树体生长不良,果实商品性下降。使用蓝板对葡萄园内蓟马发生情况进行全年监测。结果表明,元谋干热区葡萄产区蓟马在3~5月是活动高峰期,峰值出现在4月25日,诱杀到蓟马67296头,随着降雨量、空气湿度、土壤水分含量的增加,6~12月的葡萄产区蓟马的数量降低且维持在较低的数量水平,田间不同位置蓟马分布数量无显著差异。结合气象因子和综合防治方法,为蓟马的防治提供更精准和科学的参考。
Thrips are one of the main insect pests of grape in Yunnan,and their infestations are very serious especially in the early-maturing grape regions of Yunnan,which results in poor growth of vines and decreased fruit production.The occurrence of thrips in the grape vineyards was monitored with blue plate traps,and the results showed that the peak periods of thrips activity appeared in March to May in dry hot area in Yuanmou,with a peak day on April 25,on which 67296 thrips were booby-trapped.With the increasing of rainfall,air humidity and soil moisture content,the number of thrips decreased and maintained at a low level in June to December,and no significant difference was observed in the number of thrips distributed at different locations in the field.Combined with meteorological factors and integrated control methods,this observation might provide scientific reference for the prevention and control of the thrips.
