Biogrow Pheromone against small winter moth (Operophtera brumata) - Insect Control

Pheromones are chemicals exchanged between individuals of the same species that influence their behavior. Several types of pheromones are available, such as sex pheromones that attract male butterflies over long distances to females. This property can be exploited to trap pests. Pheromones are very specific to a particular species. The effectiveness of a pheromone depends on its composition, quantity, concentration and climatic conditions.

A delta trap or funnel trap containing the pheromone capsule 'Operophtera brumata' is used to capture the small winter butterfly . Hanging the trap begins in late October, when the first night frost occurs, through December, or January in the case of a mild winter. The pheromone capsule remains active for six weeks (four weeks in warm weather). It is important to remember that the pheromone trap must be used for several years to reduce the population of small winter butterflies.

To keep the pheromone scent pure, wear gloves when attaching the pheromone capsule in the trap. When using a delta trap, the pheromone capsule can be placed directly in the center of the glue plate or placed in the corresponding pheromone basket that is attached to the ridge of the trap with a suspension system. Both methods are suitable.

When using a plastic funnel trap, the pheromone pod should be placed in the pheromone basket and then clamped into the lid of the funnel trap. If there is a large population of winter butterflies, it is better to use a funnel trap. This is because the glue plate of a delta trap can be full of male butterflies overnight. If you do use a delta trap, it is advisable to order additional glue plates.

Pheromones can be stored in the freezer for 2 years . The pheromones are individually packed in an aluminum bag, so that the odors of the freezer cannot be mixed with the pheromone scent.
