一、为害情况 玉米铁甲虫,属鞘翅目,叶(虫甲)科,铁(虫甲)亚科(Hispi-nae),学名Dactylispa balyi(Gestro),土名命角(译音,懂文Meηzgok,即有角苍蝇之意)。去年发生地区颇广,广西僮族自治区西南部大新、天等、龙津三县去年早、中玉米播种面积共计61万6千亩,其中受害面积达428,574亩,占总面积69.57％。 玉米受害后,严重地造成减产失收。据不完全估计,1957年大新县桃城、榄圩、太平、福龙、荃茗和龙门六个区,仅在1,000余亩受害面积中,即损失早、中玉米
First, the damage situation Corn iron beetle, is a coleoptera, leaf (insect) Branch, iron (insects A) subfamily (Hispi-nae), scientific name Dactylispa balyi (Gestro), soil famous horns (transliteration, understated Meezgok, That is, the meaning of angular flies).
