"The cosmopolitan aphid species Myzus persicae is a key pest of peach orchards in south and southeastern Romania. The phenomenon of resistance induced by the intensive use of insecticides is a matter of
concern for farmers and protectionists, making necessary integrated measure for the control of this pest.
Conservation of natural enemy’s populations is an essential component of any management system proposed for
pest aphids. The aim of the study was to determine the structure of predatory insects associated with Myzus
persicae populations in peach orchards. The research was carried out in three orchards from two localities from
Constanta County, in peach plantations with Springcrest variety aged 7, 11 and 12 years. As a result of this
study, there were determined a total of 15 predatory insect species belonging to eight systematic families:
Coccinellidae, Chrysopidae, Hemerobiidae, Syrphydae, Cecidomyiidae, Panorpidae, Nabidae and Forficulidae,
which naturally contribute to the reduction of the green peach aphid populations.
