Definition of thrips

Categorized under "General"

Definition as written by mwhit:

Narrow-bodied (1/16") sap-sucking insect pest. Adults are black to brown, nymphs are pale yellow.

They thrive in hot, dry conditions. Damage appears as white, de-pigmented areas on petals - leaves can show silvery damage too - of some ornamentals and heavy infestations will cause distorted buds that do not open.

Controls: regular watering, preditory mites or chemical sprays such as pyrethrum, chlorpyrifos or malathion

Definition as written by JaxFlaGardener:

The name of this insect pest happens to be one of those weird words where the "s" is used both in the singular and the plural. You may have one thrips or one-hundred thrips (but you can never have a thrip or thripses).

On some ornamental plants, thrips may cause leaf-curl on newest leaves. On Ficus benjamina, the new leaves will remain tightly closed and will not open, even as the leaf grows larger.
