条螟(Proceras Venosatus walker)是为害甘蔗的主要蔗螟之一。甘蔗从苗期到生长中后期均受到条螟的为害,苗期受害造成桔心苗,伸长拔节后受害造成梢枯(死尾)或螟害节,对甘蔗的产量和糖份影响均很大。广东的珠江三角洲蔗区,进入七十年代以来,随着高产良种粤糖57/423的推广,条螟的为害也比过去日趋严重,一般产量损失15—20%。因此条螟在种植粤糖57/423为主的蔗区,已经成为影响甘蔗产量的一个主要因素。近年来我们在条螟为害较为严重的番禺县东冲公社和鱼涡头公
Proceras Venosatus Walker is one of the main sugarcane borers for sugarcane. The sugarcane was damaged by the striped stem borer from the seedling stage to the middle and late growth stage. The seedling stage caused the orange heart seedling, which resulted in the shoots withered (dead tail) Big. In the Pearl River Delta of Guangdong Province, since the 1970s, with the promotion of the high-yielding variety Yueshi 57/423, the damage caused by striped stem borers has become more serious than in the past, and the general yield loss is 15-20%. Therefore, the stem borer planted in Guangdong sugarcane 57/423-based areas, has become a major factor affecting sugar cane production. In recent years, we were severely damaged in the strip mulch Panyu County, East Chong commune and fish Edouard
