Traps allow the detection of the medfly and the reduction of damages. Functional biodiversity (i.e., predators in the ground cover) decreases the emergence of medfly adults.
Practical recommendation
• Apply control strategies accordingly to the life cycle of the medfly (Picture 1).
• Use traps composed of (i) a parapherormone (i.e., trimedlure) or food attractants; (i.e., hydrolysed pro-teins); and (ii) a pyrethroid (e.g., deltamethrin) or Spinosad (Picture 2A).
• Make your trap! Fill a transparent bottle with a 9% water solution of protein hydrolysate (or the fertiliser sulfur ammonium) and 2% borax (Picture 2B). As an alternative, attach a vial with food attractant to a ply-wood panel soaked in deltamethrin (2.8%) (Picture 2C).
• Place 50-75 traps/ha, from late August (before fruits change colour) in orchards with a minimum extension of 2-3 ha or isolated ones.
• Check available biocontrol agents (Table 1) and consider the agent biology before applying (e.g., nema-todes require the presence of pupating larvae in the soil).
• Apply cultural control methods: eliminate infestation sites and destroy infested fruits.
• Promote biodiversity (e.g., plant combinations, ground cover management, etc.) to increase predation on medfly pupae and parasitisation of larvae.
• If infestations are too high to be managed with mass trapping alone, treat with clays (kaolin at 4% concen-tration) before fruits change colour in plots below 3 ha. Treat plot perimeters and repeat in case of intense rainfalls.

EPrint Type:Practice tool
What problem does the tool address?:The Mediterranean fruit fly (medfly), Ceratitis capitata, is a key pest in citrus. Egg laying and larvae feeding have negative impacts on yield and export markets.
What solution does the tool offer?:Use sticky traps and baits to monitor and control the medfly in citrus orchards. Apply conservative and inoculative biocontrol.
