上两个星期中,我收到一些东南点发现机翼Droophila SWD幼虫活动报告,我们已经观察到北卡罗来纳州一些研究站块有SWD渗透事件。我的地块有渗透事件是件好事,因为它允许我们在这里学习SWD并提供最新信息给你,但种植场有渗透事件是另一件事情。自1月起,我们在北卡罗来纳州抓成年社工,但这些是我们记录到的最早幼虫
开工清除所有成熟果实并销毁果实(通过冷冻、“烘烤”阳光透漏塑料袋数日或从网站取出 ) 鸡蛋或幼虫可能出现在否则声音冒出果实中留下这些果实表示可能染色果实存在并可采摘
二叉开始攻击性喷雾程序( 不雨时每周一次, 雨时重新应用 ) 。 至少在两种动作模式间旋转会降低抗药性开发的可能性 。
来东东南小果园注册杀虫剂可能效果的信息 。 因为这些效果评分基础大都在美国西部完成的工作,环境条件不同,不是石块设置的 。 我们正在用I键运行多项效果测试并期望到夏中时有NC数据
3级极佳卫生实践; 清除所有成熟果实并出售或销毁它; 田里不要丢弃爪子, 并清理雨后和u选择者无选择果实为SWD幼虫水库
4级采样果并定期考虑捕蝇问题。Traps告诉你社署存在或缺席,但不完美,但有用。草莓行陷阱,靠近果实抓苍蝇最佳机率。采样果实,每次采样时要么割开它们并寻找幼虫,要么在盐水中粉碎它们(每加仑14杯盐),要么冷冻它们。盐水和冷冻会使幼虫退出果实。采样每田至少30莓

来捕捉信息
来光华采样信息
强烈鼓励所有种植者监控社署成人
前置幼虫被发现。如果成人出现而水果成熟,则推荐杀虫剂处理直至收割结束。我们希望这一策略能防止幼虫显示果实并触发这里列举的动作

I am aware that homeowners may be not be able or may prefer not to use insecticides on fruit in the gardens are yard. Unfortunately, sanitation alone will not eliminate and SWD population. However, if you can pick your fruit a bit earlier or a bit less ripe, it will be exposed to SWD for less time and will perhaps be at a lower risk of infestation. It's also important to note that while SWD larvae cause fruit to decay quicker and are unpalatable if present in fruit, they are not poisonous or parasitic. If you have inadvertently consumed fruit from your home garden that SWD larvae have been present in, they do not pose a heath risk.

This strategy is worth a shot for homeowners who can tolerate the sight of bags on their plants. In order to exclude SWD, cages should be placed before fruit begins to change color and tightly sealed at the bottom. We'll often place a piece of quilting foam between the cage and the stem of the plant to allow us to tightly tie the cage shut (with a zip tie or twine) but protect the stem from damage. Cages should stay in place until you harvest your fruit. We use organdy mesh from fabric store and sew our cages to size, but paint strainers also work in a pinch. I plan to try this method with my backyard blueberries, blackberries, and figs next year and will be interested to hear if others also give it a shot.
