香蕉象鼻虫又名蕉黑带象甲。能为害香蕉、贡蕉、大蕉、蕉麻等。香蕉产区,受象鼻虫为害很普遍,虫口密度大时招致假茎,果柄折断,往往造成蕉园严重减产,甚至全园被毁。我们十多年的实践证明,采取综合措施,防治象鼻虫的效果可达87％以上。香蕉象鼻虫的形态特征:成虫体长13—14毫米,黑色或褐色,褐色的虫体一般较大。口吻伸出,触角生于口吻之基部;胸背平,有黑色纵带两条,鞘翅纵沟明显;腹部末端外露,向腹面弯曲。卵长1.5毫米,长园筒,起初乳白色,逐渐变为半透明状,浸渍在蕉茎的分泌胶质中。幼虫无足,初期乳白色,老熟幼虫体长15～20毫米,头部红褐 Banana weevil, also known as banana black belt weevils. Can harm bananas, bananas, plantains, abaca and so on. Banana production areas, by the weevil damage is widespread, insect population caused by large stem density, stems break, often resulting in serious banana reduction, or even the whole park was destroyed. Our practice for more than a decade has proved that the effect of controlling weevils can reach more than 87% through comprehensive measures. Banana weevil morphological characteristics: adult body length 13-14 mm, black or brown, brown worms generally larger. Mouth extended, tentacles born in the base of the mouth; chest and back flat, with two black longitudinal band, sheath fin longitudinal groove was obvious; the distal end of the abdomen, bending to the ventral surface. Eggs 1.5 mm long, long cylinder, initially milky white, gradually translucent, impregnated in the secretion of plant stem gum. Lack of larvae, early milky white, mature larvae body length 15 ~ 20 mm, head reddish brown
