Mass trapping for the control of the Mediterranean fruit fly Ceratitis capitata (Diptera: Tephritidae) on fig trees in Southern Portugal (Algarve)
The main goal of this work was to evaluate the mass trapping technique of the Mediterranean fruit fly Ceratitis capitata Wiedemann based on the use of Tephri traps with the triple food attractant Biolure medfly R (ammonium acetate (FFA), putrescine (FFP) and trimethyllamine (FFT)) and with the parapheromone Trimedlure, both combined with an insecticide tablet of dichlorvos (DDVP) on fig trees. The trials took place in an orchard of the cultivar 'Bêbera branca' occupying an area of 0,2 ha and located in Tavira (Algarve-Portugal). The trials were conducted in 2013 and 2014. The mass trapping technique efficacy assessment was based on adult Medfly population expressed by recording weekly thecaptures in the traps together with the assessment of fruit damage at harvest. Trials were conducted using a density of 50 traps of each bait per hectare. Results indicated significant differences in the number of captured adults and in the fruit damage percentages between the two tested methods. More insects of the fruit fly were captured in the traps baited with the Biolure medfly R than in the traps baited with Trimedlure. Fruit damage assessment results also indicated less damaged fruits for the mass trapping based on Biolure medfly R compared to the parapheromone Trimedlure.
