Predatory Mite of Spider Mites
Identification and Biology : Adults are pear-shaped, 0.15 mm long and red-brown in color. Development from egg to adult takes from 7-9 days at 21⁰C to 3 days at 32⁰C. At 28⁰C a fourfold increase in numbers can occur within 4 days. This predatory mite does best in moderate to cooler humid conditions, but will also tolerate warmer temperatures. Adult females enter diapause in response to short days (less than 14 hours).
Target pest: Fallacis can control the European red mite (Panonychus ulmi) below economic threshold levels in fruit orchards. It also targets the Two-spotted spider mite (Tetranycus urticae), the Spruce spider mite (Oligonychus ununguis) and the South Red Mite (Oligonychus ilicis). This predatory mite is one of the most important biological control agents in berry and fruit orchards in North America.
Mode of action: Fallacis is a voracious consumer of mites and because its population increase quickly in relation to its prey, it can overtake an expanding pest population. It will leave the tree ones the prey population has been reduced since it cannot thrive on alternative food.
Introduction method and release rates: General introduction rate is 1-5 Fallacis/m2.
