探讨玉米象（Sitophilus zeamais）、米象（Sitophilus oryzae）和谷蠹（Rhyzopertha dominica）三种蛀食性害虫不同感染程度对小麦淀粉酶及过氧化物酶活性的影响及变化规律，为小麦科学储藏量化指标提供依据。选用河南产储藏2年的商用小麦，按不同虫种分组，设定不同的虫口密度和感染时间，检测小麦样品降落数值和过氧化物酶（POD）活性，并与虫口密度和感染时间作相关性分析。结果表明，随着虫口密度增加和感染时间延长，样品的降落数值呈波动上升趋势，POD 活性呈下降趋势；三种害虫侵害后的样品降落数值与感染时间均存在极显著正相关，POD 活性与感染时间均存在极显著负相关，降落数值与 POD 之间呈极显著负相关，而二者与虫口密度的相关性均不显著。

The effect of three boring pests,maize weevil,rice weevil and lesser grain borer,on amylase and peroxidase (POD)activity,and the variation was studied in order to provide quantitative parameters for grain storage scientifically.Some quantity of mixed wheat stored in Henan province for two years were taken as a test sample,which were to be infected by each kind of borers with different densities for differ-ent periods of time.The falling number and POD activity were measured at different infection time,the relativity with pest population density and infection time was analyzed.The result showed that the falling number was in the trend of increase and POD activity in the trend of decrease along with three main kinds of boring pests population density increasing and the infection time prolonging.The correlation analysis shows that the falling number was significant positive correlate with the infection time,POD activity was significant negative correlate with the infection time and the falling number,while both of them showed non -significant correlate with pest population density.
