When to use Pea and Bean Weevil trap?
Use the pea and bean weevil trap in combination with the species-specific pheromone when adult weevil activity is expected from the beginning of February onwards. Pea and bean weevil is an early pest that affects spring-sown crops of peas and beans and the traps can provide information to assist decisions about spray applications.
How does the trap work?
The trap works by attracting ground dwelling adult weevils into the cut-out holes in the green part of the trap. Adults are attracted to the pheromone which is hung inside the green part of the trap. Adults climb up into the trap and up into the white funnel and through the hole at the top. They are then caught in the clear plastic top.

Application of Pea and Bean Weevil trap
Instructions for usage:
Five traps are sited on a grass margin or headland of a field that was cropped with peas or beans in the previous year and should be checked three times each week. A threshold is reached when an average of more than 30 weevils is recorded per trap on any one occasion. When a threshold is reached, crops that have just emerged or are likely to emerge within 10 days are likely to be at risk.
Five traps per field location.
Traps should be placed in last year’s pea field 10 m apart by the second week of February.
Weevil numbers in the bulb at the top of the trap should be recorded 3 times per week.
