Mirid bugs are important pests in both integrated and organic fruit production. In a survey
in 2006 the proportion of mirids parasitized by parasitoids was investigated in 18
Norwegian orchards. More than 50 beating samples were collected from apple and pear
orchards under integrated and organic management in different areas of Norway. About
30% of nymphs of the most abundant mirid bug species, Lygocoris pabulinus, Ortholylus
marginalis and Psallus ambiguus, were parasitized. Important factors for enhancing
biological control in organic fruit production are discussed.
