Twelve strawberry cultivars established in matted row plots in 1993 were treated with insecticides for tarnished plant bug or left untreated for the 1994, 1995, and 1996 seasons. `Honeoye', `Cavendish', and `Oka' had the highest yields of marketable fruit. `Jewel', `Chambly', and `Kent' had lower, but acceptable, yields. `Lateglow', `Blomidon', `Seneca, NY1424', `Settler', and `Governor Simcoe' had lower yields than other varieties. Tarnished plant bug populations were very low during the 1994 and 1996 seasons, and thus feeding pressure may have been too low for any differences in susceptibility between varieties to be expressed. In 1995, when tarnished plant bug feeding pressure was greatest, `Oka', `Cavendish', and `Honeoye' had the lowest injury levels. `Kent' and `Lateglow' had the highest levels of injury. Insecticide sprays significantly reduced the percent of injured fruit for most cultivars, but did not significantly increase the weight of marketable fruit harvested. This is due to injury being most prevalent on lower order, and thus smaller, fruit. Cultivars that produced high yields, had low injury levels, and had the least difference between sprayed and unsprayed treatments are most likely to have resistance to tarnished plant bug injury. `Oka', `Cavendish', and `Honeoye' were the most promising cultivars in this regard.
