Abstract
長角象鼻蟲(Araecerus fasciculatus)之食性甚雜，如農產品或中藥材常受嚴重為害。該蟲在本省，年生6世代，每世代需282～86.6天，平均48.8天。卵期3～15天，平均6.1天。孵化率為98％以上。幼蟲期19～47天，平均35.6天。蛹期.天～10.天，平均71天。成蟲羽化後～6天脫離被害物外出自由活動，雌蟲1次產卵數1～3粒，最高可達7粒。每雌產卵總數21～45粒，平均334粒。成蟲壽命26～56天，平均37.0天。1對雌雄經5個月之繁殖蟲數；以玉米飼育者為136.2隻，甘藷簽為176隻，當歸136.7隻。經其消耗與為害之損失量玉米為22.3%，甘藷簽為31.4%，當歸為26.6％。蒜頭及當歸中各蟲期之冷藏致死溫度為5℃ 50天，0℃ 25天，-5℃ 10天，-20℃ 24小時。蒜頭如放置通風良好環境，用Panapfate板50g/M3藥量吊置頂面，即可燻殺蒜頭中及由外界侵入之成蟲。緊急處理用Phostoxin 3片/M3密閉燻蒸較為有效。
The coffee bean weevil, Araecerus fasciculatus (De Geer) is a serious pest attacking various stored agricultural products, like corn, sweet potato and chiretta (a kind of herb, Ligusticum acutilobum Sieb. et Zucc., Umhel-liferae ) , especially at the store house. This weevil has been known as a world wide distributed species and about six generations recorded in Taipei, the generations were overlapped so that the various stages of the pest could be found on the stored products all year around. Its egg, larva, pupa and adult lasted 28.2-(48.8)-86.6, 3-(6.1)-15, 19-(35.6)-47, 5.2-(7.1)-10.3 and 26-(37.0)-56 days, respectively to complete the adult left the infested product right after emergence, throught about 4-6 days, they started to mate and the female aid oviposition, generally a female laid 1-3 and at mostreggs per day arid 21-(33.4)-45 during its life time, the percentage of egg hatching was 98% at laboratory rearing. Concerning about food preference, the different food seemed soundly effect the weevil progeny, the fact was proved by three pairs of adults, which were fed with corn, sweet potato slice and chiretta for five months respectively under the same rearing condition, mutiplied 136.2, 176 and 136.7offsprings, the loss of the products were estimated about 22.6, 31.4 and 26.6% respectively.
To study the low thermal factor influences the development of the weevil, 4 groups of weevil feeding on garlic and chiretta at temperatures 5°C, 0°C, -5°C and -20°C were set for test, the result showed to kill all the weevils need minimum 50, 25, 10 and 1 days respectively.
For the control purpose, if garlic was attacked by the weevil, it could be kept in ventilational area and fumigated with panaplate (DDVP) 50gJm3 or phostoxin 3 tablets/m3 to obtain a successful and effective control.
