Paramecium nymph tree blocking device

Abstract

A device for hindering Drosicha corpulent nymphs from climbing trees comprises a first plate, a second plate, first double-sided adhesive tape and at least one felt strip, wherein the first plate, the second plate, the first double-sided adhesive tape and the at least one felt strip are equal in length; the first plate and the second plate are made of non-metal flexible material, and the felt strip is made of sponge or felt; the first plate is connected with the upper side of the second plate through a curved surface, an included angle from 40 degrees to 55 degrees is formed between a flat plate and the second plate, the lower side of the first plate is higher than the lower side of the second plate, the surface roughness of the side face, close to the second plate, of the first plate is 0.8 micrometer-1.6 micrometers, and the surface roughness of the side face, close to the first plate, of the second plate is 0.8 micrometer-1.6 micrometers; at least one ridgy part in a hollow strip shape is arranged on the second plate in the length direction, at least one protruding direction is pointed to the first plate, one felt strip is installed in each ridgy part and matched with the corresponding space in the ridgy part, and the side, away from the first plate, of the felt strip exceeds the second plate; the first double-sided adhesive tape is laid on the side face, away from the first plate, of the second plate and does not make contact with the corresponding felt strip. The device is good in hindering effect and protects environment.

Description

technical field [0001] The invention relates to a forestry pest control device, in particular to a tree blocking device for paramecium nymphs. Background technique [0002] At present, large poplar forests are often planted in urban landscape greening, road greening, village greening, surrounding greening and river embankment protection forests, which grow fast and have good benefits. However, poplar forests have often suffered serious damage from paramecium nymphs in recent years. After spring, there are many insects the size of sesame seeds crawling on the trunks of the poplars. In the late spring and early summer, the insects grow to the size of soybeans. The leaves on the poplar trees with many insects are few and grow listlessly. This kind of insect is called Paramecia, which belongs to the family of Homoptera and is very harmful to poplar trees. The insect also harms various trees such as Fawu and black locust. There is one generation of this worm every year. The ny...

Problems solved by technology

[0004] The existing methods for preventing and controlling Paramecia nymphs are: 1. Chemical control: After discovering that Paramecia nymphs are harmed, spray chemical pesticides on the crown of the tree, or use an electric drill to inject medicine in the trunk. There is a waxy protective layer on the body surface of the nymphs, which makes this method have limited killing effect on paramecium nymphs, poor control effect, time-consuming and labor-intensive, high cost, difficult to prevent paramecia nymphs from climbing trees, and causing damage to the surrounding environment. Pollution; 2. Biological control: Although this method is environmentally friendly, the natural enemies of paramecium nymphs, such as the red-ringed ladybug, often lag behind the paramecia nymph population, and the effect is very slow
