| 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 |
