The result showed that the peak of the western flower thrips was in the early flowering of plants, the average number was 14.8 per flow- er. The number of western flower thrips on the leaves face was more than that on leaves back, which was 3.7 and 2 per leaf respectively. The number of this insect on middle and lower leaves of the plant was more than that on upper leaves; the insect number on upper, middle and lower leaves was 2.7, 3.1 and 3.6 per leaf respectively.
