Proper
use of Pheromone Traps:
The pheromone trap is designed to monitor
and reduce pest numbers. In order to determine the population density of pest
insects and to identify pest outbreaks (monitoring), it is recommended to use 1
trap per 1 ha.
In order to determine the first flight of
the butterflies, traps should be placed in the orchard prior to apple bloom.
The trap should be placed in the crown of the tree at a height of 1.5-2 m. 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.
Trap placement:
For mass capture and sterilization of males,
it is recommended to have at least 20 traps per hectare. In case of a large
number of pest insects use at least 30 traps per 1 ha.
