Common Name: Thrips - damage
See also: adult | larva Scientific Name: Thysanoptera: several species Status: pest of many plants, particularly in greenhouses Damaging Stage: nymph and adult Injury: Thrips prefer to feed on the youngest leaves of a plant. The plant cells are punctured by the rasping-sucking mouthparts, and plant cell sap is withdrawn. Damaged foliage eventually wilts and dies. Action Threshold: Sticky traps can be used to detect thrips population levels. If thrips numbers are large, control options should be considered. Management: Integrated Pest Management strategies using a combination of cultural, biological, and less-toxic chemical controls generally work best to manage thrips infestations. |
