  Cranberry Insect Pest Monitoring in New Brunswick

C.M. Maund1

Abstract: Insect pests were monitored at a cranberry (Vaccinium macrocarpon) bog in Oromocto, New Brunswick during 1996 to determine when control methods would be required. Pheromone traps were used to monitor the following moths: cranberry girdler, Chrysoteuchia topiaria (Zeller); blackheaded fireworm, Rhopobota naevana (Hübner); sparganothis fruitworm, Sparganothis sulfureana (Clemens). The major pests were the blackheaded fireworm, trapped from 9 July to 2 August, and the cranberry girdler, trapped from 26 June to 2 August. Pheromone traps were also used to monitor for June beetle adults, and similar species, which were trapped at low levels. A survey of insect populations with a sweep net revealed no significant levels of additional insect pests. Cranberry plants were sampled for damage by the cranberry tipworm fly, Dasyneura vaccinii (Smith). An average of 10.3 % of plant tips, over the entire sampling period, had been damaged by the cranberry tipworm.
