Three rates of cuelure were compared in male annihilation blocks to assess the attraction of male Queensland fruit fly. There were no significant differences in trap captures of fruit fly between 2, 8 or 18 mL of cuelure in chipboard based male annihilation blocks. There was no repellent effect at the high cuelure rate, even in the first inspection period. At the end of the trial, chemical analysis was conducted on the core and edge positions of blocks. Cuelure, maldison and raspberry ketone were significantly related to the weight of the blocks. Cuelure levels were significantly higher in surface layers while maldison levels were significantly higher in the core position. Implications for the male annihilation technique are discussed.
