Aphids (Hemiptera: Aphididae) are regularly occurring on wheat, more or less numerous, depending of the year. Direct damage, as yield losses and spoiled the baking quality of the grain, is made by aphids feeding on phloem sap. Transmitting of viruses is very important indirect damage. Many aphid species could be found on wheat in Serbia. The most important species are: grain aphid (Sitobion avenae), bird cherry-oat aphid (Rhopalosiphum padi) and rose-grain aphid (Metopolophium dirodum). Some notes on morphology, host plants, biology, damage, distribution, vector role and most important natural enemies (Coccinellidae, Syrphidae i Aphidiidae) are given for every of these three species.
