Abstract

Twenty-one new and three commercial sugar-cane varieties were screened for posssible resistance to the sugar-cane moth borer Diatraea saccharalis at four different sites. Varietal resistance was evaluated using percentage dead hearts in young canes and percentage joint infestation in mi liable canes. Variety rankings according to both indices of infestation were site specific and in the case of dead heart rankings, time specific. These results are discussed in the context of the impact of environmental factors on varietal resistance and the need for an integrated pest management (IPM) approach to the management of the pest in Barbados.
