Evaluation of chrysanthemum flower model trap to attract two Frankliniella thrips (Thysanoptera: Thripidae)

Frankliniella occidentalis Pergande and F. intonsa Trybom (Thysanoptera: Thripidae) are anthophilous insect pests of many crops worldwide. We evaluated a flower model trap mimicking the chrysanthemum flower as a new method to attract the thrips in the laboratory and a strawberry greenhouse. Both choice and no-choice tests in the laboratory showed that the chrysanthemum flower model trap attracted significantly more adult F. occidentalis and F. intonsa compared to yellow sticky trap. Up to 4.1 times more of F. occidentalis and 5.4 times more of F. intonsa were caught in the flower model trap in the strawberry greenhouse. The flower model trap would be a good addition to the integrated thrips management, although at present it is more expensive than the yellow sticky trap.
