摘要

球莖蟎(Rhizoglyphus robini Claparede)爲唐菖蒲種球栽植時期與儲存時期爲害最嚴重之害瞞，田間栽植之唐莒蒲生育至5葉期、7葉期、種球成熟期及種球收穫期分別有78.1%，90.0%，80.0%及54.2%之種球被球莖蟎爲害，被害球上之蟎數自4至540隻。種球在試驗室內(15-28℃, 51-87%pH)儲存3個月後，發現其上之有害動物有97.9%爲球莖瞞，健全種球僅餘44.4%。
防治球莖蟎之方法包括浸漬處理與燻蒸處理。浸漬處理共試驗了18種藥劑，包括chlorobenzilate，dicofol，tetradifon，benzomate，cycloprate，triazid，azide，propargite，oxythioquinox，cyhexatin，bromopropylate，azinophos-ethyl，mecarbam，methyl demeton，methomyl，carbofuran，drawin，oxamyl。其中以bromopropylate，benzomate，methyl demeton效果最優良。若以燻蒸處理，燻蒸箱溫度爲25-38℃時，以每立方公尺一片(3g)之弱55%aluminum phosphide燻蒸被害之種球48小時，可消減所有之球莖蟎，當箱內溫度降至15-20℃時，用藥量應提高至每立方公尺2片。

Bulb mite (Rhizoglyphus robini Claparede), the most serious pest on gladiolus, attacks gladiolus corms both in the field and in storage. About 78.6%, 90.0%, 80.0% and 54.2% of the gladiolus corms were found to be damaged by this mite when the plants were at 5-leaf, 7-leaf, corm-mature and corm-harvest stage, respectively. The number of mites found on the damaged corms in the field ranged from 4 to 540. During the corm storage period, 97.9% of the animal pests was the bulb mite. Only 55.5% of the corms were left healthy after stored for three months under laboratory conditions (15-28℃, 51-87% RH).
Dip treatment and fumigation treatment were tested for the control of the bulb mite. In dip treatment, chlorobenzilate, dicofol, tetradifon, triazid, azide, propargite, oxythioquinox, cyhexatin, bromopropylate, benzomate, cycloprate, azinphos-methyl, mecarbam, methyl demeton, methomyl, carbofuran, drawin, and oxamyl were tested. Of them, bromopropylate, benzomate, and methyl demeton had the best control effect on bulb mite. Fumigation of the bulb-mite-infested corms with 55% aluminum phosphide tablet (1 tablet: 3 gram) at the dosage of 1 tab/rn3 for 48 hours killed all the bulb mites when the temperature in the fumigation container ranged from 25-38℃. The dosage increased to 2 tab/m^3 when the temperature in the container ranged from 15-20℃.
