Galendromus occidentalis is an effective predatory mite for control of spider mites and other mite species in high temperature, low humidity settings. It is an active predator of mite eggs, nymphs and adults. When compared to P. persimilis, G. occidentalis mite predators are more effective in tree-top releases and on plants with hairy leaves. G. occidentalis is also able to sustain itself on pollen in the absence of a large pest population making it advantageous in a preventive release setting.
Identification: Adults are pear-shaped, about 0.5mm long and resemble N. fallacis and N. cucumeris. Coloration ranges from beige to amber/red depending on prey consumed. Look for adults hunting in the daytime along leaf veins and over the whole leaf surface come nightfall. Mite predators are more active than pest mites and can be spotted moving around the plant in search food, while their prey are more stationary as they feed on plant tissue.
Optimal Conditions: This predatory mites do best in warm weather (80° to 110°F) and prefers 30-60% relative humidity (RH). In temperatures lower than 80°F this mite predator may go into hibernation or slow down consumption of mite. Ideal for use on fruit trees, vegetable, grape and field crops. Adults consume 1-3 pest adults per day.
Release Rates: Not recommended for use in cool, coastal areas. Some crops, including tomatoes & other highly resinous crops, require higher release rates.
- Indoors Releases: 1,000 per 500 sq. ft. bi-weekly for 2-3 applications. Release approximately 1 predatory mite per 5 pest mites.
- Outdoor Releases: 2,000-5,000 per acre bi-weekly for 2-3 applications.

G. occidentalis are effective predators of multiple species of spider mites and russet mites. Release instructions can be found below. If you are a first time user of G. occidentalis mite predators, please call us at 1-800-827-2847 to walk through application instructions and best practices.
G. occidentalis predatory mites are shipped in loose media designed to be broadcast throughout the growing area. Once you receive the mite predators, gently shake the container to distribute the mites in the media. Open the container once you are in the application area and pour contents directly onto the foliage of the affected plants. Distribute as evenly as possible throughout the whole area to be treated. If possible, avoid applying directly to flowers as the media can stick to flowers and buds.
Viability Note: If you plan to check for viability, please do so upon receipt and prior to releasing the beneficial insects. Many predators and parasites are small and can be difficult to spot once released. If you believe there are issues with viability, please contact us at 1-800-827-2847 or firstname.lastname@example.org.

Life Cycle: Galendromus occidentalis adult females overwinter within debris under plants/trees or in bark crevices. Mortality is high during the winter months. Adults emerge at first bud when temperatures increase looking for suitable prey. Females lay eggs on the undersides of leaves, in the buds and on the flowers. Hatching occurs in 1-4 days depending on temperature and humidity. Larvae and adults feed on all life stages of pest mites as they mature. Total development from egg to adult takes 6-12 days with adult females living for roughly 30 days. G. occidentalis reproduce quickly compared to other mite predators and can complete 8-10 generations per year under the correct conditions.
Shelf Life: Use within 18 hours of receipt.
