Sex pheromone/attractant based integrated insect pest management in carambola orchard
No full text楊桃是台灣的特產，果實呈星狀別緻，果肉多汁可口，頗為國人喜愛，部分則運銷國外。目前楊桃栽培面積約1,738公頃，年產量約2.7萬公噸，產值約4.8億元新台幣。台灣之楊桃害蟲種類有報導者約20 餘種，較常見者大概10 種。近年來為害普遍且嚴重，必需採取防治措施的關鍵害蟲，主要有花姬捲葉蛾、東方果實蠅、葉蝸類及柑桔粉介殼蟲等四種。本文針對數種關鍵害蟲的發生時期、為害習性、生活史及田間生態等做簡要描述，並摘要各害蟲的不同防治管理技術，尤其是花姬捲葉蛾與柑桔粉介殼蟲的性費洛蒙及東方果實蠅的雌、雄性誘引劑與相關應用技術均已成熟，已可利用做為楊桃害蟲綜合管理之基本應用技術。另外，對於未來台灣果樹實施害蟲綜合管理計畫宜加強與改進之處，亦提出討論，以供參考。
Carambola fruit is the special agro-products of Taiwan. The total planted area of carambola fruit tree is estimated to be 1,738 hectares. The annual production of carambola fruit is about 27,000 tons, and the value is NT$ 480 million. Nearly over 20 species pests were reported to have infested carambola in Taiwan. The majority of these pests cause little damage or occur only locally and sporadically, but four or more insect pests are of major economic importance, such as carambola fruit borer, Eucosma notanthes Meyrick, Oriental fruit fly, Bactrocera dorsalis ( Hendel ) , spider mites, citrus mealybug, Planococcus citri (Risso), etc.. The paper briefly described the occurring period, damage habit, life history and field ecology of the key pests on carambola, as well as their management or control tactics with available sex pheromones/attractants techniques were reviewed. The further improvement for integrated pest management or control programs in fruit crops will be discussed
