Montdorensis is a predatory mite with the Latin name Transeius montdorensis. The adult females lay their eggs on the leaf. A few days later the larvae hatch from the eggs. In total, the predatory mite goes through five stages in just a week under the right climate conditions (approximately 25 °C). This means that a large population is built up in a short time. The predatory mite is predatory from the first nymph stage.

You can use montdorensis predatory mites against a number of pests:

• Thrips
• Whiteflies
• Spider mites
• Various mites

The predatory mite is mainly effective against the hatching eggs and first two larval stages of thrips. In thrips control, the Transeius montdorensis has an advantage over Amblyseius cucumeris and Amblyseius swirskii, because they only control the first larval stage of thrips. From the whitefly the, montdorensis predatory mite eats the eggs and larvae stages.

The predatory mite is active from 10 °C. The optimum is 25 °C. The predatory mite actively searches for prey and sucks it empty. The predatory mite can then eat about 10 thrips larvae per day. Hatching Thrips eggs are also eaten by the predatory mite.

The predatory mites must be used in the crop as soon as possible after delivery. The mites produce heat and CO2 and at high temperatures they will strongly deteriorate in quality and quantity during long-term storage. If immediate use is not possible, they must be cooled to avoid high temperatures in the bags. The optimum storage temperature is 18 °C and a Relative Humidity of 80%.

Montdorensis is available in breeding sachets but also as loose material. The bags are hung in the plant. The sachets also contain a feed mite, so that the predatory mite can multiply in the sachets and will run from the bag into the plant over a period of about 4 to 6 weeks. Nowadays a lot of loose material is also blown or scattered over the plants. Often in combination with Power Food in order to build up and maintain a population in the plant faster. We have developed equipment for this to achieve a good distribution of the loose material. Spread over the entire section.
