Galendromus Occidentalis predatory mites - MI Beneficials

Galendromus Occidentalis predatory mites

Galendromus Occidentalis are a native predator mite to the West Coast of the United States, thus it has the nickname of "Western Predatory Mite".
Galendromus Occidentalis is generalist predator of spider mites and have been used most widely in the tree fruit industry on the west coast to not only control pest issues, but greatly reduces the need and cost for miticides, which in turn reduces costs for producing organic fruit.
Galendromus Occidentalis have also been shown to be effective against hemp russet mites in the Cannabis industry which has truly revolutionized the efficacy of bio-controls against the worst types of pests.

 

Identification:

Galendromus Occidentalis are only positively identified under magnification due to their resemblance to Neoseiulus californicus and Neoseiulus fallacis mites.

The adult female is slightly larger than the male at roughly 1/70 inch, the body is wider in the rear and then it tapers towards the head. They are generally an opaque white color, but will change colors depending on what they prey upon.

The larval stage has a a wedge shape and three pairs of legs (6-legged) and the nymph phases have 4-pairs of legs.

We always recommend diversity, and predator mites are no exception. Check out our combo-packs of Neoseiulus californicus and Galendromus Occidentalis

Purpose:

Galendromus Occidentalis mites is a remarkable fix to the hemp russet mite issues that have been ravaging cannabis cultivation. Further, they are also a predator to Two-Spotted Spider MItes, European Read Spider Mites and Tomato Russet Mites.

Galendromus Occidentalis is used widely in the fruit industry specifically against apple rust mites in warmer, drier climates. In apple orchards of such climates, Galendromus Occidentalis populations will manage themselves based on the amount of prey species, environmental conditions and potential side effects from toxic pesticide use.

Using Galendromus Occidentalis predator mites is truly only effective in low-humidity outdoor climates as well as indoor operations where the temperature and humidity can be effectively controlled. For indoor hemp russet mite elimination, there is not a better option than Galendromus Occidentalis.

Life Cycle:

Depending on what their food source is and where it is located, Galendromus Occidentalis females will emerge and relocate wherever prey sources are. Over the course of their ~30 day life span, they will deposit roughly 21 eggs which will hatch in 1-4 days, going through a larva and two nymph stages.

 

When there is a good food source and ideal environmental conditions, Galendromus Occidentalis can develop rapidly and go through multiple different generations. During the fall, some females will descend from the foliage to overwintering spots (like tree bark) while other will fall with the leaves into the soil/mulch layer to overwinter.

THIS IS REAL. I REPEAT, THIS IS REAL. The black mirror is real, the black mirror is really powerful, effective and 100% reliable. My name is Walter Brian, I want to thank Dada Magical for giving his black mirror to me. Since he gave me his black mirror, I became rich, successful, protected, informed and powerful. I was browsing through the internet one day when I saw multiple testimonies on how Dada Magical has helped so many people with his black mirror. I thought it was a joke at first but I gave it a try and contacted him. He sold the black mirror to me and told me how to use it and all that I need to do. I followed the instructions just as he told me and to my greatest surprise, it worked just as he told me. The black mirror is still working for me. The mirror also brings good luck, blessings and information. Contact Dada Magical now on his email; Dadablackmirrors@gmail.com and he will help you also with the black mirror just the same way he helped me. Thank you Great Dada Magical.
