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.
