Red and yellow spider catching and killing leaf

Abstract

The invention discloses a red and yellow spider catching and killing leaf which is characterized by comprising a middle plate and an adhesive film, wherein the middle plate is 1mm to 2mm in thickness and is of a honeycomb structure; honeycomb holes of the middle plate are 0.5 to 1.5 nanometers in pore diameter; the honeycomb holes are used for retaining orange juice; a layer of retaining film is fixed and coated on the lower surface of the middle plate; the retaining film is 0.2mm to 0.5mm in thickness; the upper and lower surfaces of the adhesive film are both adhesive; orange juice volatilizing holes penetrating the upper and lower surfaces of the adhesive film are densely distributed on the adhesive film; a layer of adhesive film covers the upper surface of the middle plate in an adhesion manner. By arranging the retaining film to make the orange juice be volatilized towards the adhesive film, red and yellow spiders can be caught and killed by the adhesive film on the upper surface of the middle plate; the red and yellow spider catching and killing leaf is convenient, effective, reliable, low in catching and killing cost and free of pesticide residues, so the defects of a conventional technology can be well overcome, and the red and yellow spider catching and killing leaf is simple in structure, easy to implement and quite good in practicability.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry, and in particular relates to a red 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 effectively...
