Deraeocoris lutescens is a Mediterranean species, distributed also in small numbers in Central Europe. Known mainly as an egg predator of pear psyllid Cacopsylla pyrisuga and hawthorn psyllid Cacopsylla crataegi (Herard 1986). It is also reported as a predator of aphids and mite Panonychus ulmi in apple orchards in Croatia ( Arčanin and Balarin 1972) and in pear orchards as a predator of Cacopsylla pyrisuga in France and Turkey (Herard 1986, Erler 2004).

Deraeocoris lutescens has been already registered in Serbia ( Protić 1993) but here is reported for the first time as a predator of psyllids in this country.
