%X An investigation was made in winter wheat fields to study the effects of applying wheat synomones methyl salicylate and sulcatone (6-methy-5-hepten-2-one) on the dynamic changes of Macrosiphum avenae and its natural enemies Harmonia axyridis and Aphidius avenae. The results showed that wheat synomones didn' t change the population dynamics of M. avenae significantly, but had a significant effect on the reduction of M. avenae population number. The synomones could deteriorate the existent environment of M. avenae, and make the number of alatae increased obviously. Although synomones decreased the species richness, diversity index, and evenness of natural enemy communities, the numbers of dominant natural enemy species such as A. avenae and H axyridis were increased. Applying wheat synomones was helpful to the control of M. avenae in winter wheat fields.
