摘要
用赤拟谷盗Tribolium castaneum(Herbst)成虫,研究PH3对其体内超氧化物岐化酶(SOD)和过氧化氢酶(CAT)活性的影响。结果表明PH3熏蒸后,4种不同地理种群的成虫体内,CAT酶活性都有所降低。种群NGD1降低最多,接近57%,而NGD4则只降低了19%,NGD2和NGD3的降低都在40%左右。不同地理种群的成虫体内,SOD酶活性在熏蒸后都有所增加,种群NGD1增加幅度最大,NGD2增加幅度最小。SOD和CAT活性的变化幅度与成虫对PH3产生的抗性有关,抗性越大,酶活性变化越大。
The adults of Tribolium castaneum （Herbst） were suffocated with phosphine to research the effect of phosphine on the activities of CAT and SOD. The results showed that after suffocating, the activities of CAT in four different geographical race of adults decreased. NGD1 decreased by 57% and NGIM decreased by 19%. NGD2 and NGD3 decreased about 40%. The activities of SOD in four different geographical race of adults raised. The raised rang in NGD1 were the most and the raised rang in NGD2 were the least. The change scope of SOD and CAT is related with resistance to phosphine. The more resistance, the more changes.
