Sweet potato weevil lure

Description

Used with a trap, this pheromone lure provides an effective tool for monitoring and mass trapping populations of sweet potato weevil (Cylas formicarius).

Tips for use

• Instal traps containing the lure in the field at planting
• Place a few centimetres of water in the bottom of the trap
• For the purpose of monitoring, deploy at a rate of between 1 trap per 2-5 ha
• Further R&D is required to determine the optimal rate for mass trapping, but as a guide we suggest 1 or more traps per ha
• Place traps at 30 cm above the ground, or place the top of the trap level with top of the crop canopy
• Check traps weekly – empty out captured beetles and record numbers (measure volumetrically for big catches)
• Replace lures every 4-6 weeks
