摘　　要：为评价黄板对柑橘粉虱成虫诱集效果,研究了不同黄板大小、悬挂高度、方向对柑橘粉虱成虫诱集量的影响,在此基础上进一步分析了黄板不同密度对柑橘粉虱的控制效果.结果表明,黄板悬挂不同高度对柑橘粉虱成虫诱集量有不同程度的影响,诱集量最大的为与冠层水平的黄板,为115.7头/(板·d),高于或低于冠层的黄板粉虱诱集量均有所下降,黄板在冠层下50cm粉虱诱集量最小,为76.0头/(板·d),显著低于与冠层水平黄板的诱集量.黄板大小对粉虱诱集量也有影响,40cm×25cm,35cm×25cm,30cm×25cm和25cm×20cm黄板诱集量分别为92.4,83.5,77.8和56.6头/(板·d),40cm×25cm黄板诱集量显著高于25cm×20cm黄板,但25cm×20cm黄板单位面积诱集量最高.黄板不同悬挂方向对柑橘粉虱成虫诱集量没有明显影响.黄板对柑橘粉虱控制作用明显,第8d和14d,每2株树挂1块黄板的果园防治效果分别达到了84.20%,81.64%,每1株树挂1块黄板的果园防治效果分别达到了87.02%,93.17%,由此可见,黄板诱杀可有效控制柑橘粉虱的危害.In order to evaluate the trapping efficiency of yellow sticky traps （YSTs） against Dialeurodes cirri adults in citrus orchards, YSTs of different sizes were installed at different height and in different directions to investigate their effects on trap catches of D. cirri adults. BaSed on the results of the treatments, the control efficiency of YSTs at different densities against D. citri adult population was studied. Height of YST installation showed different degree of influence on trap catches. YSTs installed at the height of the citrus canopy gave the greatest trap catches （115.7 adults/ （ trap · d））, which was significantly more than the YSTs installed at 50 cm below the citrus canopy （76.0 adults/（trap · d））. The size of YSTs also had influence on trap catches. The number of D. citri adults trapped with YSTs 40 cm×25 cm, 35 cm× 25 cm , 30 cm ×25 cm and 25 cm ×20 cm in size was 92.4, 83.5, 77.8 and 56.6 adults/ （ trap · d）, respectively, and 40 cm×25 cm YSTs caught significantly more D, citri adults than 25 cm × 20cm YSTs, but the number of D. citri adults trapped on unit area was the highest on 25 crux 20 cm YSTs. Orientation of YST installation had no significant effect on trap catches. YSTs gave obvious control on D. citri adult population and, as recorded on the 8th and 14th day after YST installation, the treatment of 1 trap per 2 trees and 1 trap per 1 tree resulted in a control rate of 84.20% and 87.02, %, and 81.64 and 93.17% , respectively. It is, therefore, concluded that adult trapping with YSTs is effective in controlling adult population of D. citri in citrus orchards.
