Controlled-release panel traps for the Mediterranean fruit fly (Diptera: Tephritidae)

Area of Science:

• Entomology
• Pest Management
• Material Science

Background:

• The Mediterranean fruit fly (Ceratitis capitata) is a significant agricultural pest.
• Current detection methods use trimedlure in Jackson traps and sticky panels, with limitations in release duration and material stability.

Purpose of the Study:

• To develop and evaluate novel controlled-release panels for trimedlure and ceralure to improve Mediterranean fruit fly detection.
• To assess the stability, release rates, and efficacy of different panel formulations under field conditions.

Main Methods:

• Development of polyethylene matrix and polymer-coated cardboard panels incorporating trimedlure and ceralure.
• Evaluation using biological (fly capture) and chemical (release rate) assays.
• Field bioassays in Hawaii and Guatemala comparing different panel types and commercial products.

Main Results:

• Polyethylene matrix panels showed brittleness and low release rates.
• Polymer-coated cardboard panels were stable and effective for up to 6 weeks.
• Farma Tech commercial panels (12.3 and 23.4 g trimedlure) remained attractive for 134 days.
• AgriSense commercial panels (10 g trimedlure, 10 g ceralure) had slower release and lower attractiveness.

Conclusions:

• Polymer-coated cardboard panels offer a stable and effective alternative for short-to-medium term Mediterranean fruit fly detection.
• Long-lasting commercial panels provide a viable, cost-effective solution for sustained pest monitoring.
• Optimized controlled-release formulations are crucial for effective insect pest management.
