How to kill red and yellow spiders

Abstract

The invention discloses a red and yellow spider catching and killing method. The red and yellow spider catching and killing method is characterized by comprising the following steps of (a) arranging red and yellow spider catching and killing leaves on a trunk or branches of a citrus tree, wherein the thickness of middle pieces in the red and yellow spider catching and killing leaves ranges from 1 mm to 2 mm, the middle pieces are of honeycomb structures and dipped with citrus juice, and the citrus juice is kept in honeycomb holes. The middle pieces are in shapes of citrus leaves, and a fixed needle is fixedly arranged at one end of each middle piece. The upper surface and the lower surface of a mucus membrane have viscidity, citrus juice volatilization holes penetrating through the upper surface and the lower surface are densely distributed in the mucus membrane, and the upper surface and the lower surface of each middle piece are respectively bonded with a mucus membrane; (b) checking, namely an inspector checks whether the citrus juice is volatilized or not; (c) observing, namely the inspector observe whether the mucus membranes of each red and yellow spider catching and killing leaf is full of red and yellow spiders. By means of the red and yellow spider catching and killing method, the red and yellow spiders can be conveniently and effectively caught and killed, the cost is low, pesticide residues are not produced, and therefore the defects in the prior art can be well overcome.

Description

technical field [0001] The invention belongs to the field of agriculture and forestry, and in particular relates to a method for catching and killing red and yellow spiders. 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 method for killing red and yellow spiders effe...
