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。
Diamondback moths have become the major pests of the crucifer. Due to the frequent application of pesticides and the drastic increase of drug resistance, it is urgent to find a new avenue for the control of the diamondback moth. At the end of 1983, the study on the information of diamondback moth was carried out in the field of forecasting and field control. After two years of experiments show that the use of sex pheromone cabbage moth measured, reducing the blind medication, saving a lot of money for pesticides (see Schedule), and achieved very good results, it is recommended more occurrence of diamondback moth vegetable area Promote the application. In field control there is also a certain effect, which must be combined with prevention and control, as one of the means of comprehensive prevention. As people abuse pesticides, various vegetable pests increased resistance, especially the diamondback moth, cruciferous vegetables has become the main pest, prevention and control of production caused by 10 to 15 days once the frequent use of drugs, a serious pollution of the environment, Pesticide residues on vegetables have aroused people’s deep concern. At the end of 1983, Guangdong Institute of Entomology and Beijing Institute of Zoology, Guangzhou Institute of Microbiology in collaboration with the sex pheromone of the diamondback moth for the prediction and field control research.
