Abstract

Leucaena, a tree legume with potential to greatly improve cattle performance, has not been readily adopted in northern Queensland primarily due to prevalence of the psyllid (Heteropsylla cubana) insect in higher rainfall zones. Psyllids reduce edible biomass in leaves by 40–52%, combined with a 46–83% reduction of stem yield (Bray and Woodroffe 1991). Losses to the Central Queensland beef industry due to psyllid impact on animal performance are estimated at $2 M per year (Mullen et al. 1998). Cultivar Redlands is a psyllid-resistant leucaena variety recently developed by Meat and Livestock Australia (MLA) and the University of Queensland.
