Anthocoris nemorum is noted as a predator of many insect species, in the first place Hemiptera , Diptera , eggs of Lepidoptera and mites ( Herard 1986, Wheeler 2000b, Sigsgaard et al. 2006), already registered as a predator of both Cacopsylla pyrisuga and Psyllopsis fraxini ( Herard 1986). It is also largely reported as an efficient predator of apple psyllid Cacopsylla mali in Norway ( Jonsson 1983). In England, Hodkinson and Flint (1971) determined Anthocoris nemorum as a predator of Psyllopsis fraxini collected from ash, while in Germany Novak and Achtziger (1995) registered it as a predator of hawthorn psyllids Cacopsylla melanoneura and Cacopsylla peregrina . Sigsgaard et al. (2006) note Anthocoris nemorum as a more polyphagous species than Anthocoris nemoralis . They also determined in experimental conditions that Anthocoris nemorum prefers aphids to psyllids, and has a preference for laying eggs on apple rather than on pear.

Anthocoris nemorum is an Eurosiberian species, introduced to North America in order to control Cacopsylla pyricola just like Anthocoris nemoralis , but without satisfactory results ( Herard 1986).

Anthocoris nemorum is reported here for the first time as a predator of psyllids in Serbia.
