Biology of the codling moth (Cydia pomonella)
The adult codling moth (cydia pomonella) is a prolific butterfly that attacks apples and pears. The female lays 30 to 50 eggs, which she generally deposits from late April onwards, on the leaves of the trees concerned (apple trees, pear trees), on stems or on fertilized flowers. The caterpillars then quickly penetrate the fruit before restarting the cycle 2 to 3 times a year.
How to use the codling moth pheromone for apples and pears?
With the help of gloves, place the codling moth pheromone for apples and pears in the pheromone trap of your choice (a funnel-type moth trap is recommended). Then place 1 trap every 200 m or 4 traps per hectare (for monitoring).
Replace the pheromone after 6 weeks with a new one, from April to September). The pheromone trap allows you to spot flights by capturing male moths, whose scent is reproduced by the pheromone. This way you know when to treat.
What to do if you catch codling moths in your pheromone trap?
When your trap catches 5 codling moths in 10 days, your harvest is compromised. Use the biological insecticide Solabiol 10 days later to treat, when the caterpillars have hatched. A natural insecticide can also be used. Also consider the anti-codling moth protective netting, which gives excellent results..
