Spider Mite Tetranychus urticae "Two-Spotted" or "Red Spider Mite"
   The two-spotted spider mite or red spider mite is a major pest in vegetables, tropicals, and other ornamentals. It's tiny size makes it difficult to see. They prefer to feed from the bottom side of leaves located in the tops of plants where it is warm and dry, although as they travel along the plant, feeding marks can be found along the main vein of leaves near the petiole. As populations increase, plant damage spreads across the leaves.

Spider mites feed on plant cells and produce characteristic small, yellowish, speckled feeding marks. The feeding marks are usually the first sign of a mite infestation and are often confused with some fertilizer deficiencies. Fine, silken webs can be detected on heavily infested leaves and flowers with these plant parts quickly withering and turning brown.

   Many insecticides have little or no affect in controlling spider mites. Their small size, their ability to exist close to the veins of the plants and because they are a different species of pest than other insects, controlling by spraying is extremely difficult.

   Spider mites are sensitive to day length and are capable of diapausing (hibernating) within cracks and crevices of your structure. If you had spider mites last year, chances are excellent they will continue to be a problem this year.

   Spider mite populations can explode under conditions of high temperature (above 85° F.) and low relative humidity (below 60% RH).

SPIDER MITE CONTROLS


Spider Mite Predators
   When predatory mites are used as recommended to control this pest, success is practically guaranteed. These predatory members of the mite family will multiply nearly twice as fast as the spider mite population. Predatory mites only feed on other mites, they do not feed on plants.

   Misting systems can help raise the humidity, cool the plants and slow the reproduction of spider mites. High temperature strains of predators are also available.

   At an average of 68° F., predatory mites multiply at a weekly rate of approximately 4.6, while spider mites multiply at a weekly rate of approximately 2.7. About four days after a predatory mite egg is laid, it hatches and begins feeding on spider mites.


PP Phytoseiulus persimilis.

  A predatory mite (Family: Phytoseiidae) This is the most frequently used mite predator to control two-spotted spider mites in greenhouses and outdoor crops grown n mild environments.
General appearance and life history:
Adult females are approximately 0.5 mm long, reddish in color, pear shaped and active at room temperature. About 80% are females. At optimum temperatures P. persimilis can develop from egg to adult in 7 days and live for up to 1 month. A well-fed female will lay about 50 eggs in her life time. Prey consumption is up to 7 adult spider mites or 20 eggs per day.
Environment:
Ideal temperature range is 70 - 85oF (20 - 30oC) with relative humidity of 70 - 80% inside the plant canopy. Minimum temperature for activity is 50oF (10oC). This predator does best when humidity is 60% or higher with a temperature range of 55o - 105oF.
Application Rate: Rates will vary depending on crop and level of pest infestation. Typical inoculation rate is 50/m2 (1 / 5ft2) or 5 -10/plant. Predators should be released regularly every 2-4 weeks. Click Here for Release Instructions

As a preventative, introduce Phytoseiulus persimilis, Mesoseiulus longipes, or Neoseiulus californicus at the rate of 1 predator for every 52ft of greenhouse area, soon after transplanting. Repeating the introduction two weeks later will insure overlapping generations of the predators. For control of an existing problem, introduce at the rate of 1 predator for every 25 to 50 spider mites. The more predators you release, the quicker you will gain control. Release instructions are included with each shipment.

   We recommend this handy 30X pocket microscope to aid in identification of these and other insects. Part # 5E217 priced at just $9.95. click here to see a more information on this item.

Spider Mite Predator - Feltiella acarisuga

Feltiella acarisuga is a predator midge used against Spider Mites. The adults fly around the plants, laying their eggs in the Spider-Mite colonies. The eggs soon hatch and the larvae devour the Spider Mites. Feltiella acarisuga can be used in low humidity environments where the Spider Mite Predators would have difficulty reproducing.

cyclamenmite2.jpg (17090 bytes) Cyclamen Mites

The damage caused by a cyclamen mite is vary similar to a russet mite. Female Cyclamen mites will lay 10 to 40 eggs in a 12 to 16 day life cycle. Females can reproduce without mating.


Tomato Russet Mites

Infestation leads to significant bronzing (rust) of leaves and stems. The damaged areas often crack and become distorted. Symptoms first appear at the base of the plants and gradually spread upwards. Most significant damage occurs on the tomato. The leaves may desiccate and drop off and infested plants are often killed. The Tomato Russet Mite is pale yellow-brown about .15 - .18 mm long and wedge shaped. With a high infestation, it is usually best to spray with sulfur then follow up with predatory mites.

Life Cycle

Development from egg to adult includes 
two nymphal stages and is completed in just over 2 weeks.

Spider mites and Russet mites - Amblyseius andersoni

Amblyseius andersoni is a predatory mite that can be used in the control of a range of mite pests. This predatory mite is ideal for vegetables, hardy ornamentals and fruit crops, controlling red or two-spotted spider mite, fruit-tree red spider mite, and russet mites.

Adult female mites lay single eggs onto leaf hairs, and these eggs hatch after 2-3 days to give larvae. As with other mites in the same family, these moult to produce protonymphs and then deutonymphs as they grow. All

mobile stages are predatory, and will feed on eggs, juveniles and adults of spider mites. They are also able to feed on Eriophyid mites, commonly known as Rust or Russet Mites, which are tiny, worm like mites which can cause major damage on some crops

Release rates at a typical value of about 50 - 100 / m2 (5 - 10 sq ft).
In nursery & greenhouse crops, predators are often released every 2-4 weeks.
