Mesoseiulus longipes

Mesoseiulus longipes predatory mite


Mesoseiulus longipes is a predatory mite used to suppress pest mites in warm and dry environments. More heat tolerant than Phytoseiulus persimilis, it is used mainly in the suppression of two spotted spider mite at high temperature (37°C - 98°F). M. longipes are effective in temperatures up to 100° F, although a comparable increase in humidity is required.

Adults are pear-shaped, 0.5 mm long, with 8 long legs. They can vary in colour from cream to red. The immature stages are generally a semi-transparent cream colour with only 6 legs. The eggs are oval and 0.3 mm in diameter.
