Table 4 The time (days ± SE) spent at each instar (days ± SE) of Locusta migratoria nymphs (solitarious phase, Minamidaito strain) that were reared in isolation and fed with one of barley chromosome addition lines of wheat (2H–7H), barley cultivar ‘Betzes’ (B) or wheat cultivar ‘Chinese Spring’ (CS, control) until ecdysis to the 5th nymphal instar. The number of individuals examined is shown in Table 3
