From 2004-2006 we surveyed aphids in cereal fields in Serbia. The spatial distribution among the sampling units was evaluated using the parameters of Taylor power law. In our study of three cereal aphid species (Sitobion avenae, Metopolophium dirhodum, and Rhopalosiphum padi, Taylor slope (b) values were indicative of an aggregated distribution among sampling units, although M. dirhodum showed a weaker aggregation trend on wheat then on rye. Also, in the paper we discussed relationship between the spatial distribution of aphids and their natural enemies.
