摘　　要： 采用小区田间试验法筛选防治星室木虱(Pseudophacopteron canarium Yang et Li)的速效、长效药剂。结果表明,单药剂处理组喷施25%噻虫嗪WG 7 500倍稀释液后平均防效为79.90%,且药剂持效期较长;混合药剂处理组喷施2.5%高效氯氟氰菊酯EW 2 500倍稀释液+25%噻嗪酮WP 1 000倍稀释液、2.5%高效氯氟氰菊酯EW 2 500稀释液+25%噻虫嗪WG 7 500倍稀释液、24%灭多威SL 1 000倍稀释液+25%噻嗪酮WP 1 000倍稀释液后,其平均药剂防效分别为90.23%、91.53%和90.07%;与24%灭多威SL 1 000倍稀释液处理相比差异均达极显著水平;各药剂处理与空白对照相比差异均达极显著水平。 Field plot experiment was adopted to screen rapidly available,long acting pesticide to control Pseudophacopteron canarium.The results showed that among single reagent treatments,the average control effect of 25% thiamethoxam WG 7 500 times dilution was 79.90%;and the effective period was long.Among mixed reagent treatments,the average control effect of 2.5% effective cyholothrin EW 2 500 times dilution＋25% buprofezin WP 1 000 times dilution,2.5% effective cyholothrin EW 2 500 times dilution＋25% thiamethoxam WG 7 500 times dilution,24% methonyl SL 1 000 times dilution＋25% buprofezin WP 1 000 times was 90.23%,91.53%,90.07%,respectively,which were very significantly higher than that of 24% methonyl SL 1 000 times dilution.And the control effect of each pesticide treatment was very significantly different from that of the blank control.
