AH00012 - Improved Protein Bait Formulations for Fruit Fly Control

This project was initiated to meet a recognized national need for improvements in baiting technology for controlling fruit flies. More effective, longer lasting, lower toxicity baits were required for field control in endemic areas and for eradication and suppression programs in fruit fly exclusion areas in southern Australia. The project involved collaboration between fruit fly researchers from three state departments of agriculture. USDA researchers with specialist expertise in fruit fly bait formulation were involved in a technical advisory capacity. The phytotoxicity of new and older bait formulations was evaluated in a wider range of fruit fly host crops. Although thickened baits generally outperform standard baits, they are more likely to cause damage in sensitive crops and care must be taken to avoid contact with fruit when applying bait in these crops.
