Abstract：To develop and apply novel sticky traps for advancing the green ecological control of Frankliniella occidentalis infestations,we conducted experiments to investigate the trapping efficacy of different sticky boards[varying in different colors(yellow,blue,white and pink),hanging height,deployment method,and density]on Frankliniella occidentalis on strawberry crops.Based on optimal trapping performance,sticky boards were selected and supplemented with pollen,nectar,and sucrose to compare attractant effects.Pink sticky boards demonstrated superior trapping capacity(1 487 individuals/board),followed by white sticky boards(971 individuals/board),both outperforming yellow and blue sticky boards.H2 treatment(The trap lower edge was 0.2 m above strawberry canopy)achieved the highest capture(1 663 individuals/board).The trapping efficiency ranked as L1(vertical)>L3(45° angle)>L2(horizontal)>L4(vertical cylindrical)>L5(horizontal cylindrical).40 sticky boards hung per 667 m2 was the most effective.Over time,adding nectar proved to be the most effective in trapping Frankliniella occidentalis on strawberries,with jujube nectar(2 058 individuals per board at 10 days)outperforming citrus nectar(1 918 individuals per board at 10 days).In conclusion,the trapping effect of 40 pink sticky boards with jujube nectar hung vertically per 667 m2 and the lower edge of the color boards 0.2 m from the top of strawberry plants on Frankliniella occidentalis on strawberry was the best.
