Description

Spider mite larvae, nymphs and adults feed on the underside of the leaves and cause yellow spots,later even yellow leaves. Plant cells turn yellow, which can be seen on the upper surface of the leaf as small yellow spots. This reduces the photosynthetic area of the leaf and the plant gets out of the physiological balance. This results in decreased plant growth and production. Finally the crop may die from the infestation. Nymphs and adults produce webbing that can cause cosmetic damage to the crop. If large numbers of spider mites are present, plants may be completely covered with webs.

Release rates:

  • For tomatoes and cucumbers, 1 predator per plant plus 1-2 per infested leaf.
  • For other greenhouse crops, tropical plants, and outdoor gardens, 2,000 per 3,000 sq. ft.
  • For bedding plants, 1,000 per 10,000 sq. ft.
  • For large agri-business, 5,000 - 20,000 per acre depending on infestation.

Galendromus occidentalis is a very versatile mite predator and tolerates high temperatures low and high humidity (40-85%) well, both indoors and out. Does best in warm weather (80° to 110° F). Tolerates low humidity of inland valleys. Does not do well in cool coastal areas. Goes into diapause (hibernation) in colder temperatures. Recommended for greenhouses only if plants are maintained as low as 40% relative humidity. It is native to California and has ben researched for spider mite control in almonds, grapes, and many other ornamentals and plants. This predator is well adapted for outdoor use and can perform in hot situations where humidity remains above 40%. Use G. occidentalis to control spider mites, two spotted mites, Russet mites, and others on gardens, greenhouses, and orchards of all types. Adults eat 1-3 pest adults or up to 6 pest eggs/day. Release rates indoors, 2-3/sq. ft. bi-weekly, 1-2 applications; outdoors, 5,000-20,000/acre, bi-weekly, 1-2 applications.
