蛴螬是当前最主要地下害虫之一,为了减轻地下害虫调查时的劳动强度,作者利用地下害虫的趋性诱集,两年来初步试验已获结果。在小麦播种前,于9月中、下旬,按50厘米的间隔,播种小麦,每穴播种30—40粒。播后10天左右,发现麦苗受害后检查诱集虫数,每穴挖查面积10平方厘米,深20厘米。试验证明,穴播小麦可诱集中小型蛴螬,而以中型的为多(即大黑、暗黑等优势虫种);穴播小麦诱集的虫数与诱集区附近挖查的数量,无明显差异。
Scabies is one of the most important underground pests in the world. In order to reduce the labor intensity of underground pest surveys, the authors used the trapping of underground pests to induce the results of preliminary tests in two years. Before sowing of wheat, in mid-September and late september, sowing wheat at intervals of 50 cm and sowing 30-40 seeds per hole. About 10 days after sowing, we found that after the wheat seedlings were found, the number of trapped insects was found. Each hole was dug for an area of 10 square centimeters and a depth of 20 centimeters. The results showed that the number of moths trapped in small-sized wheatgrass was smaller than that in medium-sized moths.
