补充资料:桔二叉蚜(black citrus aphid)
桔二叉蚜(black citrus aphid) 茶树芽叶害虫之一,又名茶二叉蚜、可可蚜,属同翅目蚜科,学名为Toxoptera aurantii Boyer de Fonscolombe。 中国各茶区均有分布。聚集于芽梢嫩叶背面刺吸为害,致芽叶拳缩,生长停滞,并排泄“蜜露”,诱致煤病。芽叶连同虫体采制成干茶,茶汤暗而混浊,带有腥味。一般常以春茶受害较大。还为害油茶、咖啡、柑桔、可可等。 形态:分有翅蚜和无翅蚜两种,有翅蚜长约2mm,黑褐而有光泽。触角第3-5节依次渐短,第3节有5-6个感觉圈排成一列。前翅中脉分二叉,腹部背侧有4对黑斑,腹管短于触角第4节,尾片短于腹管,中部较细,端部较圆,且有12枚细毛。 生活习性:一年发生20余代,偏北方茶区以卵在叶背越冬,南方则多以无翅若蚜在叶背越冬,甚至无明显越冬现象。2月下旬始孵,4月下旬至5月中旬呈现虫口高峤,夏季转少,9月下旬至10月中旬虫口又有所回升,直至深秋出现两性蚜交配繁殖,11月中旬前后在叶背产出黑而有光泽的卵粒越冬。 防治:通常可喷40%乐果或50%辛硫磷3000倍液,50%敌敌畏,200倍液等或拟除虫菊酯类农药6000-8000倍液。 |
