Thrips-associated damage (‘silver damage’ symptoms) in tomato ‘Moneymaker’ plants irradiated with supplemental UV for (A) 0, 30, 60, 120, or 180 min d⁻¹, or (B) 0, 15, 30, or 45 min d⁻¹ for a period of 14 d and subsequently used for non-choice whole-plant thrips bioassays. Silver damage was evaluated at 7 d after thrips infestation. Data are means (+SEM) of n = 4–5 individual plants in (A) and n = 6–7 individual plants in (B). Different letters indicate significant differences among groups as determined by GLM followed by Fisher’s LSD test (P≤0.05).
