| Research Abstract |
Locusta migratoria feeds on various Poaceae but barley. Barley genes related to feeding deterrence are useful for developing novel resistant crops. We investigated the effects of barley cultivar Betzes, wheat cultivar Chinese Spring (CS), and six barley chromosome disomic addition lines of wheat (2H-7H) on locomotor activity, feeding behavior, survival and development of L. migratoria. Locomotor activity was similar in nymphs kept with wheat and 2H-7H in an actograph, whereas it was generally high in those kept with barely. Feeding tests suggested that barley genes related to inhibition of feeding by L. migratoria are located on barley chromosomes 5H and 6H and those related to the palatability of plants on chromosomes 2H, 5H and 6H. Rearing experiments suggested the presence of barley genes negatively affecting the survival and growth of locust nymphs on chromosomes 5H and 2H, respectively, and the effects are phase-dependent. The results were published in Suematsu et al. (2013).
