Phytoseiulus persimilis is a small predatory mite (approximately 0.5 mm) used in the biological controlling of spider mite. Adult are fast movers with a orange to bright reddish orange colour. The predatory mites are slightly longer than the spider mites. Eggs are oval an twice as large as the eggs of their opponent, the spider mites.
Life cycle and relative effectiveness
An (female) adult has the ability to lay 60 eggs evolving from egg to larvae within two or three days. During the larval stage, the predatory mite does not need food, nymphs and adults feed themselves by eating all different stages of the spider mite. Phytoseiulus persimilis does not hibernate and stays active throughout the whole year. The predatory mite consume between 5 to 20 preys per day. A major and primary task is to create a good humidity level for this predatory mite. A humidity of less than 70%, makes it hard to survive.
Application and dose
Phytoseiulus persimilis is most active at a temperature that regular exceed 20°C with a minimum humidity level of 70%. Make sure the materials will be plotted on the leaves. The materials must be slightly turned and shaken before application.
Storage and handling
Phytoseiulus persimilis supplied in bottles (sawdust or vermiculite) containing 2.000 predatory mites. Keep the bottles horizontally, in darkness, at a temperature between 8°C – 10°C. Maximum storage time of two days.
