Cyrtomenus bergi是近年来在哥伦比亚发现的一种为害木薯块根的昆虫。受这种害虫的螯针蜇刺的木薯块根,往往出现褐斑或黑斑,从而失去经济价值。大田试验表明,C.bergi喜甜种木薯而几乎不为害苦种木薯。种植菽麻能抑制C.bergi的虫口。杀虫剂以乐果的效果为最好。 Cyrtomenus bergi is an insect found in Colombia in recent years that harms the roots of cassava. The cassava root stung by the stinger of this pest tends to have brown spots or dark spots, losing its economic value. Field trials showed that C.bergi likes sweet cassava and hardly harms cassava. Cynanchum growth can inhibit C. berberi’s mouth. Pesticides to dimethoate as the best.
