Effect of Sticky Traps with Different Colors on Trapping Insects in Loquat Orchards

[Objective] The aim was to screen out sticky traps with good trapping effect.[Method] Sticky traps with eight selected colors respectively including yellow,black,red,blue,purple,white,green and grey were used in loquat orchards to trap insects.[Result] The yellow sticky trap could trap nine familia of insects best,especially Psylla chinensis Yang et Li and Aphididae;and the next was green sticky trap which was effective for five familia of insects,including Psylla chinensis Yang et Li and Aphididae.Homoptera showed strong phototaxis,so they were suitable to be controlled by the sticky trap.[Conclusion] The research result provides theoretical basis for the integrated control of pests by using sticky trap.
