【摘要】 小菜蛾己成为十字花科的主要害虫。由于施药频繁,抗药性剧增,因此防治小菜蛾寻找新的途径,迫在眉捷。于1983年底开展了小菜蛾信息应用于测报和大田防治的研究。经两年来的试验表明,应用小菜蛾性信息素进行测报,减少了盲目用药,节约了大量的农药钱(见附表),取得了相当理想的效果,建议在小菜蛾发生较多的蔬菜区推广应用。在大田防治方面也有一定效果,须与化防结合,作为综防的手段之一。由于人们滥施农药,各种蔬菜害虫的抗药性剧增,小菜蛾尤甚,已成为十字花科蔬菜的主要害虫,生产防治上造成10～15天用药一次的频繁局面,严重污染了环境,蔬菜上的农药残留,己引起人们的深切关注。于1983年底广东省昆虫研究所和北京动物所,广州市微生物研究所合作,开展了小菜蛾性信息素应用于预测预报和大田防治的研究。更多还原

【Abstract】 Diamond back moth Plutella xylastella(Hnnaeus) has become a main pest of Cruciferae. Due to the frequent application of pesticide, the resistance to the action of insecticide increases acutely and therefore, it is very urgent to find a new way to control cabbage moth.It was carried out the study on the application of monitoring and indicating by means of sex pheromone of diamond back moth and control of D.moth in 1983. The tests in two years showed that monitoring and indicating D. moth could reduce the blindness in application of pesticide and save much of money and it also could get a fairly reasonable effect. It is recommend that this method is spreaded and applied in the cabbage area where D. moth severely infests. Indeed it can get afairly good result to control the D. moth in field but it must be combined with chemical control as one way of the integrated pest managements.更多还原
