摘　　要：为探寻桑拟轮蚧Pseudaulacaspis pentagona(Tagioni-Tozzetti)有效的生态控制方法,采用目测调查法确定了花椒园内桑拟轮蚧的诱集植物,比较了该虫在大豆与马铃薯上的扩散能力、间作大豆和马铃薯与施用杀虫剂对桑拟轮蚧的控制效果及对产量和产值的影响。对花椒园桑拟轮蚧有引诱作用的植物有20种,其中大豆与马铃薯的诱集效果最好,桑拟轮蚧在大豆和马铃薯上的平均扩散半径为3.32 m和2.14 m,诱虫率分别为88.4%和84.4%。间作大豆和马铃薯对桑拟轮蚧的相对控制效果较好,达97.4%,与化防园及间作-化防园的效果无显著差异;间作园中作物的净产值及净增值均较好,显著优于化防园及对照园,与间作-化防园无明显差异。表明在花椒园内间作大豆与马铃薯可有效控制桑拟轮蚧的发生,并有增产增收的效果。In order to further understand the effective ecological pest management of white peach scale, Pseudaulacaspis pentagona, visual observation method was used to investigate the trap plants of P. pentagona. The dispersal ability of P. pentagona on soybean and potato plants,the control effect of intercropping and insecticide application and their effects on yield were compared. There were 20 species of trap plants of P. pentagona in Zanthoxylum bungeanum gardens,and soybean and potato had the highest attractiveness to P. pentagona. Dispersal radii of P. pentagona on soybean and potato plants were 3. 32 m and 2. 14 m,with attractive rates of 88. 4% and 84. 4%,respectively. The control effect of intercropping on P. pentagona was 97. 4%,and didn't show significant difference with chemical control and intercropping-chemical control. Net output and income increase in intercropping gardens were higher than those in control and chemical control gardens,without significant difference from intercropping-chemical control gardens. In conclusion,Z. bungeanum intercropped with soybeans and potatoes could control the occurrence of P. pentagona and increase the yield and benefits.
