| Latin name: |
Hercinothrips femoralis,
Heliothrips haemorrhoidalis and Echinothrips americanus |
| Common name: |
Banded Greenhouse Thrip,
Greenhouse Thrip and Black Thrip |
| Description: |
Thrips are slender and
about 1/8" long. Their coloration is black to banded to
nearly a translucent color. At times some are winged. |
| Hosts: |
We have only seen them on
Ficus nitida, Golden Pothos and Chamaedorea palms.... but they can
infect other plants |
| Life cycle: |
Eggs are laid on or in
plant tissues. The egg to adult cycle takes 18 to 21 days. |
| Natural control: |
Natural control is
difficult because the Thrip is embedded in tightly curled
leaves or deep in the shoot apex. Spray with Safer's Ultra Fine
Oil weekly until no sign of Thirp is present. |
| Chemical control: |
Add systemic to soil such
as Marathon. Spray with Orthene or any pesticide labeled for Thrip.
As with any chemical be sure to follow label directions and wear
the appropriate saftey equipment. |
