Proper use of Pheromone Traps:
The pheromone trap is designed to monitor and reduce pest numbers.
In vineyards it is recommended to place traps diagonally 1 trap per 3 ha. For mass capturing it is recommended to place 20-30 traps per ha (at a distance of 25-30 m from the edge of the plantation and 30 m between traps). The trap is placed on the second support wire at the level of bunches. Rows where the traps are located should be delimited to simplify subsequent counting.
Prior to the first flight of the butterflies, the traps must be checked on a daily basis, and after the first butterflies have been captured, the traps must be checked every 5-7 days. Pheromone dispensers and adhesive tapes can be replaced as needed.
Protective measures are based on the results of the monitoring of population density of pest insects.
For mass capture and sterilization of males, it is recommended to have more than 20 traps per hectare. In case of a large number of pest insects use 30 traps per 1 ha.
