摘要
对海南地区9个品系的扁谷盗进行了抗药性测定,结果表明,9个品系的扁谷盗抗药性差异显著,抗性系数在125～2556之间,其中8个品系集中在1300～2556之间。并对其中抗性系数为1790倍的长角扁谷盗进行了实仓熏蒸试验,发现经过气密性改造压力半衰期为60s仓房的杀虫效果明显好于未经改造的仓房。
The resistance of 9 stains of stored grain insect pests, such as Cryptolestes was detected in Hainan. The result showed that the resistance of 9 stains of stored grain insect pests had a significant difference and the resistance coefficient was between 125 and 2566, however, 8 stains of stored grain insect pest coeffi- cient is between 1300 and 2566. The field trail of one stain insect with 1790 resistant coefficient was also detected. The result showed that the effect of pest insects control in grain warehouse with 60s half life of pressure after airtightness transformation was better than in warehouse without transformation.
