水稻象鼻虫又名稻象虫(黑壳虫),在黔南州为害较普遍。成虫在秧田期和本田期为害,致使叶片穿孔,稻株折倒或折断,严重地影响水稻的正常生长。幼虫在本田内为害,一般都聚集在表土内,以腐植质和稻的须根为食,使稻株产生“座兜”现象,生长不良,成熟不一致甚至不结实或结实不饱满而导致减产。 Rice weevil, also known as rice worm (black beetle), damage is more common in Qiannan Prefecture. Adults in the seedling stage and Honda period damage, resulting in leaf perforation, rice plant collapse or broken, seriously affecting the normal growth of rice. Larvae damage in Honda, generally gathered in the topsoil to humus and rice fibrous roots, so that rice plants have a “pocket” phenomenon, poor growth, maturity inconsistent or not full or not full and lead to reduced production.
