Insect pests and their predators were sampled in Canterbury white clover crops during the 1994-95 season. Bluegreen aphid and potato mirids occurred early (late October to mid-November) during the season and were a potential cause of major injury to developing flowerheads. Australian crop mirid, wheat bug, brown shield bug, and spittle bugs occurred later in the season during January and were more likely to affect seed fill and resultant seed quality. Bluegreen aphids reached an overall maximum number of 800 per m2 during early December, while potato mirid nymphs and adults were found in significantly (P
