采用生物化学方法 ,就β -谷甾醇 (β -sitosterol)、瑞香亭 (daphnoritin)以及狼毒色原酮 (chamechromone) 3种化合物对菜粉蝶 (PierisrapaeL .) 5龄幼虫中肠酯酶活性的影响进行了测定。结果表明 :处理 72h后 ,β -谷甾醇 3种化合物都明显降低了幼虫中肠酯酶活力
Effects of three compounds β - sitosterol, daphnoritin and chamechromone on esterase activity in midgut of Pieris rapae L. 5th instar larvae were studied by biochemical methods The measurement was carried out. The results showed that all the β - sitosterol compounds significantly reduced the midgut esterase activity
