The coddling moth (Cydia pomonella) is a common pest. It is a pest that causes considerable economic loss, especially in apple and pear production. Damage to fruit is caused by the larval stage (caterpillar) of the moth.
Adult moths occur in
If the temperature is at least 18°C, female moths start laying eggs 3 to 6 days after emerging from cocoons. After 5 to 20 days, depending on climatic conditions, a caterpillar hatches from its egg and moves from the leaf to penetrate a fruit. One caterpillar can damage several fruits.
By the end of August, after feeding inside the fruit for about 3 weeks, caterpillars leave the fruit and find a place for hibernating (fissures on the trunk and branches, rocks and fence posts). Next May the larvae pupate and a new generation starts.
Damaged fruit is recognizable by the brown-rimmed holes in the skin. Underneath these holes, the caterpillar has tunneled its way through the fruit flesh to the core. This tunnel may contain the brown, granulated excrement of the caterpillar. Damaged fruit ripens earlier than healthy fruit and falls prematurely, which causes yield loss.
Granupom is a selective biological insecticide, based on the Cydia pomonella (Codling moth) granulosis virus, for the control of Codling moth in fruit production.
Treatment has to be applied in relation with duration and intensity of moth flights, which can be determined by using pheromone traps.
In general, a treatment with 500 ml/ha is sufficient.
For the first treatment, you can use a dose of 300 ml/ha, and the remaining quantity (200 ml) can be used for 2 or 3 additional sprays at 1-week intervals.
* Granupom is only allowed in Belgium.

For application in fruit production, different kinds of pheromone lures are available. The pheromone lures are sold in packages of two lures, and last 5 to 7 weeks. Store lures in a refrigerator or freezer.
Here is a list of pest insects for which pheromone lures are:
Adoxophyes orana Summer Fruit Tortrix
Cydia pomonella Coddling moth
Synanthedon myopaeformis Small red-belted clearwing
Zeuzera pyrina Leopard moth
Cossus cossus Goat moth
Hedya dimidioalba Pear leaf blister moth
Leucoptera scitella Spotted tentiform leafminer
Lymantria dispar Gypsi moth
Pandemis heparana Dark fruit tree Tortrix (moth)
Spilonota ocellana Eye spotted bud moth
Period of treatment
By monitoring the Codling moth flight fecundity can be exactly determined and treatment can be applied at the right moment.
Damage treshold
When more than 25 moths/ha are captures, the economic damage trehold is exceeded, and it is time to spray.
