摘要: 甘薯小象鼻虫,主要以幼虫在薯块和薯蔓基部为害。被害处变黑、发苦,并有特殊的腥臭味,不能食用;也不能作饲料。关于甘薯小象鼻虫的发生情况,1934年浙江昆虫局曾进行过调查。而比较系统的调查研究始于1956年以后。 一、甘薯小象鼻虫的种类 甘薯小象鼻虫的学名,最早在1792—1794年Fabricius订为Brentus formicarius(印度种)。1807年Olivers订为Cylas formicarius Fab.。1875年Summers订为Otidocephahus elegantulus。1918年Pierce根据成虫触角和颜色差异,认为为害甘薯Cylas属的象鼻虫有三种,另两种为Cylas turcipennis Boheman;Cylas femoralis Faust。
