Tuta absoluta dangerous and risky in ongoing heat

With increased temperatures, Tuta absoluta can quickly reproduce. Tomato growers have long been trying to conquer this miner moth. It is therefore important that from the beginning of cultivation, the crop is monitored by way of hanging Delta traps containing attractant (pheromone).

Not yet done this? Start as quickly as possible. It is important to know what is happening in the crop, especially with the miner moth Tuta absoluta lurking about. The advice is to hang 4 delta traps per hectare containing the pheromone Optima. This pheromone attracts the males, so that there can be no reproduction. Optima works for five to six weeks. Make sure that the pheromone is put in the delta trap with tweezers.

Miner moth Tuta absoluta
Tuta absoluta can reproduce quickly and has a life cycle which varies from 29 to 28 days. As long as there is food, then the caterpillars will not hibernate. A female can lay 260 eggs during her life. This happens primarily in leaves, but also in stalks and fruit.

The predatory insect Macrolophus pygmaeus is the most important enemy of the miner moth. Because of the cold and dark spring, the population of Macrolophus pygmaeus is slightly retarded in its development. Therefore, it's vitally important to know what is in your glasshouse. By means of monitoring and capture techniques (delta traps, Tutasan), you can slow down the population until a good population of Macrolophus pygmaeus is present.
