Abstract: Insect pests were monitored at two cranberry (Vaccinium macrocarpon) sites in Maugerville, New Brunswick during 2000. The first site was monitored to determine when control measures would be required. The second site was monitored to determine the incidence of cranberry insect pests in an unsprayed area. This site was unsprayed since it was a new site with the first commercial harvest occurring in the following year. Pheromone traps were used to monitor the following moths: blackheaded fireworm, Rhopobota naevana (Hübner); cranberry girdler, Chrysoteuchia topiaria (Zeller); sparganothis fruitworm, Sparganothis sulfureana (Clemens), cranberry fruitworm, Acrobasis vaccinii Riley. Results from site 1: blackheaded fireworm, trapped from 30 June to 27 September; 2) cranberry girdler, trapped from 19 June to 27 September; 3) cranberry fruitworm, trapped from 14 July to 4 August; 4) sparganothis fruitworm, trapped from 14 July to 20 September. Results from trap captures provided information for timing of insecticide applications. Plants were sampled to determine the 50% out of bloom stage, which occurred on 16 July. This date was used for determining the appropriate time to apply a control measure for the cranberry fruitworm. A pre-harvest assessment, of six hundred cranberries on 27 September revealed 97.5% undamaged, none damaged from fruitworm insects, 2.5% damaged from unknown causes (including physical damage). Results from Site 2: 1) blackheaded fireworm, trapped from 30 June to 20 September; 2) cranberry girdler, trapped from 27 June to 14 September; 3) cranberry fruitworm, trapped from 14 July to 18 August; 4) sparganothis fruitworm, trapped from 14 July to 29 September. The 50% out of bloom stage occurred on 9 July. A pre-harvest assessment of two hundred berries revealed 89.5% undamaged, 0.5% with cranberry fruitworm damage, 0.5% with sparganothis fruitworm damage, 1% with unknown insect damage, 8.5% deformed from unknown causes (including physical damage). Visual field inspections at both sites revealed no obvious signs of plant damage from other cranberry insect pests. The cranberry tipworm, Dasyneura vaccinii (Smith), was not present in samples at both sites.
