摘要
2007—2009年,采用在普通玉米田(先玉335)中混种少量甜玉米(吉甜6号)作为诱虫植物并于灌浆期对其不处理或定期(07-25,08-09,08-23)于穗上喷施辛硫磷乳剂(40%,15mL)等措施,抵御白星花金龟为害。试验结果表明:未用化学药剂处理的混种田内,普通玉米平均穗损失值(0.39)低于对照田普通玉米(1.03),甜玉米平均穗损失值(1.63)高于对照田甜玉米(1.50)。以14d为间隔期,喷施辛硫磷于甜玉米穗上,混作田内的普通玉米平均穗损失值进一步降低。据此得出初步结论:用甜玉米作为诱虫植物,抵御白星花金龟对普通玉米的为害切实可行。
White spotted flower chafer （Coleoptera ： Scarabeidae ： Cetoniinae） （WSFC）, Protaetia brevitarsis, feeding on developing corn ears causes losses in quality and quantity in China. Considering these losses and the pollution by excessive chemical pesticides use, it is important to find novel measures for controlling this serious pest. Therefore, sweet corn （Jitian 6） was deployed as trapping crop in the common corn field against WSFC. Phoxim insecticide （40% , 15 mL） was sprayed on developing sweet corn ear approximately in 14 days interval to reduce the damaging beetle population. The result suggested that the sweet corn is an appropriate trapping crop for common corn against WSFC, and can reduce the damage value after insecticide application.
