The dynamics of occurrence, the infested parts of host plants, and the species of aphids (Aphididae) infesting maize were identified in research carried out in Krzeczowice (49°59’ N; 22°27’ E) near Przeworsk between 2005 and 2008. The research demonstrated three peaks in the development of aphid population size. The first peak (the most abundant) was observed in the latter third of June or in the first half of July. The second peak of population size was observed in early August or in the second half of this month, while the third peak of population size was recorded in the middle or at the end of September. The most important species infesting maize plants during the analyzed period were: Rhopalosiphum padi L., Metopolophium dirhodum Walk., Sitobion avenae L. and Rhopalosiphum maidis Fitch. Moreover, in 2007, Tetraneura ulmi L. was detected on maize roots in the investigated region for the first time ever.
