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 find out the effective ecological control method of Pseudaulacaspis pentagona (Tagioni-Tozzetti), visual tracing method was used to determine the trap plants of Pseudaulacaspis pentagona, Effect of Intercropping Soybeans and Potato and Application of Insecticides on Control of. There are 20 kinds of plants that attract bait in Caragana korshinskii. Among them, soybean and potato have the best trapping effect. The average diffusion radius of Sanguismecilon in soybean and potato is 3.32 m and 2.14 m, Respectively 88.4% and 84.4%. The relative control effects of intercropping soybean and potato on P. maculata were 97.4%, which showed no significant difference compared with those of chemical defense and intercropping - chemical prevention and control. The net value and net added value of crop in intercropping garden were better Better than the anti-Park and the control garden, and intercropping - Chemical Park no significant difference. The results showed that soybean and potato could be controlled in the pepper garden effectively to control the occurrence of S. crassipes and to increase yield and income.
