Tarnished plant bug feeds on developing seeds and fruit tissue of strawberries. The wild species Fragaria virginiana displays resistance and has been crossed with commercial day-neutral strawberries, producing resistant hybrids. The purpose of this study was to elucidate possible mechanisms of resistance and rank the resistance of hybrids. The effect of pollen load was also examined. Field trials compared four commercial day-neutral cultivars on three farms in southern Ontario on a weekly basis. Cultivar Fort Laramie consistently had lower damage compared to other cultivars at all sites. Laboratory experiments verified resistance and assessed the relationship of pollen to fruit damage. Caged choice and no-choice bioassays determined families 703, 704 and 708 and Fort Laramie consistently showed resistant qualities and reduced damage. Susceptible plants with pollen had higher damage and resistant plants did not. This study shows resistant genotypes were consistent and that pollen load plays a role in susceptibility.
