摘要
【目的】了解广西葡萄一年两收栽培模式下,粘虫板对葡萄蓟马的诱杀效果及其田间发生规律,为葡萄蓟马达到有效防控提供参考依据。【方法】在广西,‘桂葡3号’葡萄的两个生长季中,悬挂不同种类(蓝色、黄色、黄色信息素)、不同间距(3、4和5m)、不同高度(1、1.5和2 m)的粘虫板,通过在特定时间内调查粘虫板上蓟马的虫口数来评价粘虫板对葡萄蓟马的诱集效果。【结果】在葡萄一年两收栽培模式下,蓝色粘虫板对葡萄蓟马的诱杀作用好于黄色、黄色信息素粘虫板;蓝色粘虫板间距为4 m时对葡萄蓟马的诱杀效果好于蓝色粘虫板间距为3和5 m;悬挂高度为2 m的粘虫板对葡萄蓟马的诱杀效果较好;蓝色粘虫板的防治效果达到45.8%~49.6%。葡萄花期蓟马迅速增加,在幼果期前后达到最高峰,果实膨大期后葡萄蓟马虫口数逐渐减少。【结论】在葡萄一年两收栽培模式下,第2个生长季蓟马虫口数要高于第1个生长季,葡萄花期蓟马迅速增加,在幼果期前后达到最高峰,果实膨大期葡萄蓟马虫口数逐渐减少。通过悬挂蓝色粘虫板高度为2m,间距为4m来诱杀葡萄蓟马的防治效果最好,可达49.6%。
【Objective】The study aims to understand the effect of field sticky card on the grape thrips trapping and the occurrence regularity under two-crop-a-year grape cultivation system in Guangxi and provide reference for the effective control of grape thrips.【Method】During the two growing seasons of Guangxi grapes,the grape thrips trapping effect was evaluated by different kinds( blue,yellow and yellow pheromones),spacing( 3,4,5 m) and heights( 1,1. 5,2 m) of sticky card for‘Guipu No. 3'grapes. 【Result】Under two-crop-a-year grape cultivation system,the trapping effect of blue sticky card was better than the yellow and yellow pheromones sticky card; blue sticky card spacing in 4 m showed better grape thrips trapping effect than those in 3 and 5 m; The suspension height of 2 m presented the best trapping effect of grape thrips; The trapping effect of blue sticky card could reach 45. 8 %-49. 6 %. The grape thrips increased rapidly during the period of flowering,and reached the peak in the young fruit stage,then the grape thrips larvae decreased gradually after fruit enlargement period.【Conclusion】Under two-crop-a-year grape cultivation system,the grape thrips of the second growing season were higher than those of the first growing season. The grape thrips increased rapidly during the period of flowering,and reached the peak in the young fruit stage,then the grape thrips larvae decreased gradually after fruit enlargement period. the control effect of grape thrips trapping could reach49. 6 % by hanging blue sticky card of 2 m height and 4 m spacing.
