中文摘要:
      利用捕食螨防治柑橘全爪螨Panonychus citri已有大面积应用,但捕食螨田间防治效果常受到果园使用化学农药的影响,相应配套技术是捕食螨应用的瓶颈问题。2010年6~10月,在广东省四会市罗源镇柑橘园,分别采用五种处理方式(常规化学农药;化学农药加巴氏新小绥螨Neoseiulus barkeri;单独使用矿物油乳剂;单独使用巴氏新小绥螨;矿物油乳剂加巴氏新小绥螨)防治柑橘全爪螨,设不采取任何防治措施的样地为对照。试验结果显示,各处理的种群干扰控制指数分别是3.7195、1.4942、0.2439、0.2053、0.0488,校正虫口减退率分别是-271.95%、-49.42%、 75.61%、 79.47%、95.12%。化学农药防治对柑橘全爪螨的控制作用不理想,影响了巴氏新小绥螨的持续控制作用;巴氏新小绥螨能较好地发挥对柑橘全爪螨的控制作用,矿物油乳剂表现出较好的长期控制效果,矿物油乳剂配合巴氏新小绥螨对柑橘全爪螨有较好的协同控制作用。
英文摘要:
      The field application of predatory mites for controlling Panonychus citri usually was non ideal due to the usage of chemical pesticides. The experiments were carried out in a citrus orchard in Sihui City, Guangdong Province, during June to October 2010 Five treatments were set, including (1) chemical pesticides spraying; (2) chemical pesticides spraying andNeoseiulus barkeri releasing; (3) mineral oil spraying only; (4)N.barkeri releasing only; (5) mineral oil spraying and Nbarkeri releasing No treatment as control.The interference index of population control was 3.7195, 1.4942, 0.2439, 0.2053, 0.0488, and the corrected population falling rate was-271.95%,-49.42%, 75.61%, 79.47%, 95.12% respectively. The results demonstrate that mineral oil and Nbarkeri alone provide better control effect than the traditional chemical control onP.citr. And the control effect of mineral oil combining with predatory mites onP.citri is optimal.
