Abstract

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 I50 in vitro on lavae phenoloxidase activity with apigenin, vanillic acid and kojic acid were 77. 66, 724. 50 and 82. 70μ g/ 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 μ g/mg).
