摘要
运用联合国粮农组织(FAO)1975年推荐的测定储粮害虫磷化氢抗性的方法,对采自辽宁大连地区的玉米象和赤拟谷盗等2个品种7个品系的储粮害虫进行了抗性测定。试验结果表明,大连地区玉米象和赤拟谷盗均为低抗品系。通过对试验结果进行分析,提出延缓害虫对磷化氢抗性发展的相应对策,为今后科学防治储粮害虫提供了一定的参考依据。
The FAO （1975） recommended the determination of stored grain pest resistance to phosphine. Seven strains of stored grain pests from the two varieties of maize weevil and Tribolium castaneum which were collected in Dalian area of Liaon- ing province were determined. The results showed that maize weevil and Tribolium castaneum in Dalian area had low levels of resistance. By the results analysis, the corresponding countermeasures to delay pests resistance to phosphine were put forward, which provided certain reference for the future scientific control of stored grain pests.
