- Abstract
BACKGROUND: Public opposition to aerial application of sex pheromone for mating disruption of light-brown apple moth LBAM), Epiphyas postvittana (Walk.), in California stopped its further use in the ca $74 million eradication programme in 2008, nderscoring the need for other eradication tactics. It is demonstrated that pheromone-treated sterile Mediterranean fruit flies medflies), Ceratitis capitata Wied., can disrupt communication inmalemoths. RESULTS: Medflies topically dosedwithmoth pheromone (E)-11-tetradecenyl acetate showed a no observed effect level (NOEL) of 10 µgfly-1,with increasing toxicity from 30 to 100 µgfly-1.Greater potency and longevity of attraction and lowermortality were achieved usingmicroencapsulated pheromone. Releases of 1000 pheromone-treated medflies ha-1 preventedmalemoth catch to synthetic lures in treated 4 ha plots for 1 day in suburban Perth, Australia. Releases of ca 3000 pheromone-treated medflies ha-1 disrupted catch to single female moths in delta traps, and to synthetic pheromone lures. Percentage disruption on the first four nights was 95, 91, 82 and 85%. CONCLUSIONS: Disruption of moth catch using pheromone-treated medflies is a novel development that, with future improvement, might provide a socially acceptable approach for application of the insect mating disruption technique to control nvasive insects in urban environments. Adequacy of payload and other issues require resolution.
