The utility model relates to a slow releasing device for a predatory mite, which is specially used for releasing natural enemies of harmful mites. Its feature is that the release is made of a structure can accommodate the amount of predatory mite culture materials and contains a certain amount of predatory mites in the sealed container, the outer part of the sealed container is preset release window above the sealed container is also provided with a tie for hanging. The use of the method is as follows: each container is about 300 to 500 mites, loaded with the feed together with the load, sealed with the reserve. The position of the release is selected on the main rod of the branch of the tree crown, and is hung on the main rod by a tether attached to the container. The release time can be maintained for 15-30 days. Compared with the prior art, the utility model has the advantages of convenient operation and release, due to the release of windows open can form a rain cover, not exposed to wind and rain, not affected by the environment, is not affected by pesticide and human factors, which can be widely used in various orchards (such as citrus), biological control of tea garden, bamboo forest and garden city, can be reached the long-term control of pest mites harm to.

技术介绍
目前,各种农、林作物害螨包括红蜘蛛、锈壁虱、跗线螨、粉螨等的普遍发生、猖厥危害已成为包括中国在内的世界性大问题,国际上已把叶螨(红蜘蛛)与实蝇、桃蚜、稻螟、盾蚧列为五大害虫,并作为利用天敌进行综合治理的目标。小虫成大灾已成为我国近年农业生产中虫害的发展趋势,例如柑桔红蜘蛛、锈壁虱是我国柑桔产区重要害螨,严重影响柑桔的产量与品质,每年用以防治的农药使用次数多(柑桔、苹果、枸杞、草莓、棉花等年用药次数竟达10-20次,害螨抗药性剧增,已达到无药可治的境地。此外,北方枸杞、油松、南方竹林、松树、城市园林、花卉、茶园、大棚蔬菜均不同程度遭受到螨类的危害。为了消除农药残留,生产无公害食品、减少环境污染、改善人类生存环境是各级政府和科研人员急待解决的问题之一,因此,使用生物防治策略,其中利用有益螨类(捕食螨)控制有害螨类是当今国际上防治害螨的最佳途径。目前欧洲、北美国家一些公司已进行了捕食螨的工厂化生产,外国在苹果、桃树上释放害螨天敌(捕食螨)成为生物防治的重要手段,目前在国内我们也已开始在柑桔园和竹林中试验使用胡瓜钝绥螨作害螨天敌(捕食螨)防治柑桔蜜柚、脐橙树上红蜘蛛锈壁虱等害螨,具有良好的防治效果。但传统的释放方式原始简陋有的是直接采用在塑料布片内用花粉饲养的捕食螨连同塑料布片折好后(用别针)挂放在作物、果树枝杆上,这种释放法易受环境影响,捕食螨容易一下全跑光,释放量有限,迂下雨天遭雨水冲刷时损失量大,使用后留下的大量塑料布片还会造成环保问题;还有的 ...
