Abstract

A Teflon ®-walled mating table to assess pheromone-based mating disruption of lepidoptera was constructed and field-tested using the eyespotted bud moth, Spilonota ocellana (Denis and Schiffermuller) (Lepidoptera: Tortricidae), in an apple orchard in the Okanagan Valley of British Columbia. Sentinel females were placed individually on mating tables on eight different nights during July 1996. The percentage of mated females ranged from 20-100%, with an average of 55.8% (n = 47). One female died and only three escaped. Females of the obliquebanded leafroller, Choristoneura rosaceana (Harris), also mated when placed on the tables in the field, suggesting that the table may have potential for use with many species, particularly those that are too small to be tethered.

Key words: mating table; pheromone-based mating disruption; sentinel female; Spilonota ocellana; Choristoneura rosaceana
