甘藷害蟲之生態與防治

Abstract

甘藷為一營養價值高且具保健之糧食作物，一般以食用塊根為主，但近年來亦培育出以食用葉部之品種，提供葉用蔬菜的另一種選擇。由於甘藷葉片再生補償能力強，大多數食葉性害蟲對塊根甘藷產量之為害不大，害蟲以直接為害塊根或莖蔓之甘藷蟻象( Cylas formicarius (Fabricius))、猿葉蟲 (Corasposoma aduricum Mannerheim) 及甘藷螟蛾 (Omphisa anastomosalis (Guenee))為主。 Sweetpotato is an important food crop as well as a healthful vegetable. The root tuber of Sweetpotato is rich in nutrition, vitamins and minerals, and the leaves are rich in food fibers and antioxidization element. The leaf-eating pests are negligible to tuber production due to powerful compensation of leaves.
