中文摘要：在室内测定了吡虫啉与杀虫单混配对水稻褐飞虱nilaparvata lugens和二化螟chilo suppressalis的联合作用,并进行了田间试验。结果表明吡虫啉与杀虫单复配对褐飞虱、二化螟有相加和增效作用,以配比1∶20～1∶40增效作用最好。吡虫啉对二化螟有较高的毒杀作用,以点
英文摘要：The bioactivity and co-toxicity coefficent of mixed imidacloprid and monosultap to Nilaparvata lugens(St?l)and Chilo suppressalis(Walker)were determined in the lab,and their efficacy was tested in the field.The results showed that the co-tox
