Thrips Frankliniella occidentalis, Thrips tabaci

There are two types of thrips that can be pests to greenhouse operations, the Tobacco or Onion thrips (Thrips tabaci) and the Western Flower Thrips (Frankliniella occidentalis). Although Western Flower Thrips have been found to vector Tomato Spotted Wilt Virus and are slightly different in size than the Onion Thrips, the life cycle and feeding habits are similar. Thrips cut a slit in a plant and deposit their eggs into the slit. The eggs hatch into a nymph that feeds on the plant for 7 - 14 days.

Thrips are very tiny insects (about 1/50th of an inch), but signs of their feeding are very noticeable. Thrips (nymphs and adults) scrape plant tissue to induce the flow of plant juices. This scraping causes the tissue to desiccate and gradually enlarge to form a ‘window’. They also feed on small fruit, pollen, and flower parts. Full-grown nymphs drop to the growing media (some reports indicate 90% - 95% of the Western Flower Thrips drop to the growing media - the remainder pupate on the plants) and go through a pre-pupae and pupae stage before emerging as an adult and climbing up the plant to feed, mate and repeat their life cycle. Adult thrips are capable of flying.

Thrips are capable of pupating and multiplying most rapidly during periods of warm, dry weather. When growing media and greenhouse floors are kept on the dry side, thrips will multiply rapidly.

THRIPS CONTROL


We have not found an individual method that can control thrips. However, a program using a combination of these methods listed appears to maintain populations below destructive levels.

Thrips Predator Amblyseius cucumeris

These predatory mites are tan-orange in color and similar in looks and movement to the spider mite predator. The predator population must be built up and established early in the crop, even before evidence of thrips. These predators search the plants and feed on thrip nymphs and immature spidermites. Introduce at the rate of 1 predator per ft2, two weeks after transplanting. Repeat applications every month during periods of warm, dry weather. These predators provide a means of control in the foliage. If NO THRIPS are present, A. cucumeris can survive on pollen

Guardian Steinernema Sp

These beneficial parasites have worked in our greenhouses to control thrips. They have been found effective to control most insects that spend a portion of their life cycle in the growing media, such as the Onion thrips. "GUARDIAN" provides a means of control within the growing media and earthen floors. For more information on Hydro-Gardens' "GUARDIAN", see the section on Broad Spectrum Controls.

Orius Minute Pirate Bug (Orius insidiosus)

Orius can be distinguished by their large red eyes. The adults are about 1/8th inch long (3cm) and brown to black in color. All stages can catch and kill small insects. They hold their prey with the forelegs and suck them empty. Orius are cannibalistic and should be released immediately upon receipt. They fly fairly well and thus are very mobile. Many growers have reported that Orius not only gets rid of their Thrips problem, but also reduces their problems with Whiteflies, spider mites and other pest insects. Orius is a welcome addition to our thrips control.

                           Application Rate = 1 per 20 - 40Sq/Ft every four to eight weeks.

Amblyseius swirskiis - a predatory mite that breeds extremely quickly under warm and humid environmental conditions. It predates on whiteflies, thrips and other pests. In the absence of prey it can also survive on the plant, feeding on pollen or mould. It prefers a warm humid climate, but can survive cooler nights during the winter months in semi-protected crops by moving lower down the plants, where it benefits from the warmer micro-climate closer to the ground

Application Rate = 1 per 6 Sq/Ft every six to eight weeks.

Stiky Traps - Click Here for more information.

Many insects are attracted to the color yellow. These insects can be captured by hanging cards around your plants. Captured adults will not lay any more eggs on your plants. Yellow Stiky traps provide a means of controlling the flying stages of most pest insects.

"Fly-Barr" Insect Barrier - Click Here for more information.

When your exhaust fans are running, your intake vents are like a vacuum cleaner catching everything flying near the vents. Covering these intake vents with INSECT BARRIER will greatly reduce the introduction of unwanted pests into your greenhouse. Clean INSECT BARRIER reduces your airflow less than 5%.
