Mustard, Brassica juncea (L.) Coss, was used to attract and accumulate Lygus lineolaris (Palisot de Beauvais) in cotton plots to evaluate their effects on various cotton cultivars. Mustard planted in rows adjacent to cotton in a 2×2 row pattern was cut to force plant bugs to move to cotton plants when they had grown to the 6-leaf stage. The method offers cotton breeders a new way to screen their progeny rows for tolerance to tarnished plant bugs. A highly significant interaction cultivar × plant bug treatment for 1st harvest yield indicated considerable genetic variability for sensitivity to tarnished plant bug damage in the early stages of fruiting.
