不同颜色粘虫板对枇杷果园昆虫的诱集效应

目的]筛选诱集效果较好的粘虫板。方法]选用黄色、黑色、红色、蓝色、紫色、白色、绿色、灰色8种颜色的粘虫板对枇杷果园内的昆虫进行诱集。结果]黄色粘虫板的诱集效果最好,诱集昆虫种类9科,对梨木虱、蚜虫的诱集效果较好;其次为绿色粘虫板,诱集昆虫种类5科,对梨木虱和蚜虫也表现出较好的诱集效果。同翅目昆虫的趋色性较强,适合选择色板诱集防治。结论]为利用粘虫板进行害虫综合防治提供了理论依据。

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.
