[這篇文章最後由phaler在 2005/09/12 01:33pm 第 1 次編輯] 請問用酒精棉片擦拭葉片有效嗎? 多久要擦拭一次? 根要不要也擦拭? 如何從葉片的變化看出來有沒有效果? 能不能比照醫院的 SARS 消毒雙手的方法, 直接噴霧酒精溶液於整個栽植區?

如果蘭花數量不多話 想辦法增加環境溼度才是上策
-- 作者: phaler >是把他搽掉 要很用力擦嗎? 會不會傷到葉子?

紅蜘蛛碰到酒精不會死嗎? 如果不會, 擦掉他們的作用不就是只能除掉大隻的?
-- 作者: 飛蝴蝶 小隻的一樣擦的掉,酒精還有一個作用就是兼殺菌。
-- 作者: Speciosa My place has been kept very wet and humid but red spider mites appeared from time to time because my place was warm and crowded with too many Phalaenopsis species plants. Currently, I use 3 electric fans to help to constantly circulate the humid air around to keep red spider mites away. Now, I have no more problem with red spider mites. The reason, I think, is because red spider mites do not like to settle in places with good air movement. To prevent my plants from being blown too dry by the 3 electric fans, I simply have to adjust the frequency of watering to 3 times daily.
-- 作者: phaler 我用兩支風扇, 可是紅蜘蛛依然猖獗. 尤其颱風後更是一發不可收拾. 我觀察被侵犯的植株要不是停止生長就是葉片黃化甚速. 昨天我很仔細地擦遍每一株. 今天葉片上的咬痕依在, 但是再擦拭, 棉片上就沒有灰褐色了. 這樣是不是清乾淨了?

Alchol can be used to wipe out the red spider mites on the infected leaves, but the bite marks (colourless) will remain (less visible).

If you can also reduce the temperature of your balcony area (for example by putting up a shade net), you have a good chance of saying sayonara to the red spider mites.
