摘要
用芹菜素(apigenin)和曲酸(kojicacid)浸渍处理甜菜夜蛾(SpodopteraexiguaHubner)5龄幼虫,试虫体重日增长值明显降低,而用香草酸(vanillicacid)浸渍处理后的幼虫体重与对照相比无明显差别。体外抑制实验表明,芹菜素、香草酸和曲酸对试虫酚氧化酶活性抑制的I50分别为77.66、724.50和82.70μg mL;体内抑制实验表明,当用上述3种化合物(1000μg mg)处理幼虫48h后,酚氧化酶活力抑制率分别达到40.05%、8.44%和42.29%。
Effects of three natural compounds (apigenin, kojic acid and vanillic acid) on the phenoloxidase activity in \%Spodoptera exigua \%Hubner were studied. The results showed that the growth of the lavae of the tested insect reduced sharply when it was treated by apigenin and kojic acid but it does not difference significantly by vanillic acid compared with the controlled experiment. The I\-\{50\} \%in vitro \%on lavae phenoloxidase activity with apigenin, vanillic acid and kojic acid were 77.66, 724.50 and 82.70μg/mL respectively. The inhibiting rate \%in vivo \%corresponding on phenoloxidase were 40.05%, 8.44% and 42.29% respectively with the three compounds (1 000 μg/mg).
