Maize is one of the most important plants in the
western side of Romania. During 2002-2005, the research carried out in

pointed out the presence of many damaging species. The most important
damaging species concerning the attacked percentage were: Tanymechus
dillaticolis (47-69.5%), adults of Diabrotica virgifera virgifera (34.6-
40.33%), Oulema melanopa (27.9 - 32.5%), Opatrum sabulosum (17.5-
31.0%), Ostrinia nubilalis (18.87-25.5%) and Aphis maidis (7.13-16.6%).
Larvae of Diabrotica virgifera virgifera caused characteristically stalk
bending in 4.42-11.08% plants from all the investigated plants. The
