Red and yellow spider killing leaf

Abstract

The invention discloses a red and yellow spider killing leaf. The red and yellow spider killing leaf comprises a middle sheet (1) and viscous films (2), wherein the thickness of the middle sheet (1) is 1-2mm; the middle sheet (1) has a honeycomb structure; the diameters of honeycomb holes of the middle sheet are 0.5-1.5 nanometers; the honeycomb holes are used for holding orange juice; the upper surface and the lower surface of each viscous film (2) are viscous; orange juice volatilizing holes (2a) are densely distributed in each viscous film and penetrate in the upper surface and the lower surface of each viscous film; and the two viscous films (2) are respectively adhered to the upper surface and the lower surface of the middle sheet (1). By the red and yellow spider killing leaf, red and yellow spiders can be killed effectively. The red and yellow spider killing leaf is low in cost; pesticide residue is avoided; and the shortcomings in the traditional technology can be overcome well. Moreover, the red and yellow spider killing leaf is simple in structure and easy to implement, and has high practicability.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry, and in particular relates to a red and yellow spider hunting and killing leaves. Background technique [0002] The red yellow spider is a kind of pest. It has only a sense of taste but no vision. It is sensitive to citrus flavor and mainly feeds on citrus, which leads to a significant reduction in the yield of citrus. At present, red and yellow spiders are generally killed by spraying pesticides. Although this chemical treatment method can kill red and yellow spiders, it will cause pesticide residues. Now, in order to ensure the quality of citrus and avoid pesticide residues, the method of spraying pesticides cannot be used to kill red yellow spiders at present, so it is urgent to solve the above-mentioned technical problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a red and yellow spider killing leaf which can effecti...
