松毛虫赤眼蜂和螟黄赤眼蜂羧酸酯酶性质比较研究

Abstract

Abstract: The biochemical and toxicological properties of carboxylesterase (CarE) were investigated in Trichogramma dendrolimi and T. chilonis. The optimal reaction time of Care with a-NA was 40 minutes. The Care activity mainly distributed in 0-1OD/(mg.min)in T. dendrolimi and1-4OD/(mg. Rain)in T. chilonis respectively. The comparison of Michaelis constants (K_m) ofCare between T. dendrolimi and T. chilonis indicated that the affinity of the latter to substrate was stronger than that of the former. There was no significant difference of Care inhibition between T. denclrolimi and T. chilonis when used paraoxon as inhibitor. The inhibition of paraoxon to the carboxylesterase of T. dendrolimi was much stronger than that of TPP.

Key words: Trichogramma dendrolimi, T. chilonis, carboxylesterase, insecticide
