Transeius montdorensis is an active predatory mite that contributes to prevention and control of pests such as thrips, whitefly and mites. Transeius montdorensis controls thrips in the first and second larval stages. The predatory mite can withstand high temperatures and dry conditions, and is also active at lower temperatures and low light levels in the winter. Even with low numbers of pests, Transeius montdorensis can survive on alternative foods such as pollen.
Life cycle and efficacy
Adults (females) lay their eggs on leaf hairs. After 1 or 2 days the eggs hatch into larvae. There are then two nymphal stages before they become adult insects. The mites are predatory from the first stage. At a temperature of about 25°C the cycle from egg to adult takes only 7 days, so a population can be built up quickly.
Shake and turn the bottle before use. Scatter or blow the material onto the leaves. The number of predatory mites to deploy will depend on the crop and the pest population. Please consult your pest control adviser for the correct numbers to deploy.
Transeius montdorensis is supplied in a 1-litre bottle with 50,000 predatory mites (nymphs and adults), or in a 5-litre bucket with 250,000 predatory mites (nymphs and adults). Transeius montdorensis can also be supplied with in a box with 250 breeding sachets, containing a minimum of 350 predatory mites per sachet. The shelf life is 1 to 2 days if the bottles are stored lying down in the dark and at a temperature of 15-18°C. There must also be adequate ventilation, to prevent accumulation of CO2.
