Method for killing longhorn beetle larvae with microwave

Abstract

The invention discloses a method for killing longhorn beetle larvae with microwave. The method comprises the following steps of: (1) detecting the distribution of longhorn beetle larvae on a trunk; (2) determining a microwave irradiation range; (3) preparing a microwave irradiation machine; (4) respectively and forcibly colliding pressure contacts on two arc reflecting plates of the microwave irradiation machine in the step (3) to the trunk with wormholes, so that the pressure contacts are automatically closed to form a circular sealed microwave irradiation cavity and the wormholes are located in the sealed microwave irradiation cavity; (5) starting a microwave emitter for irradiation; (6) irradiating with the microwave irradiation machine within the irradiation range of the step (5); (7)irradiating with the microwave irradiation machine within the irradiation range of the step (5); and (8) detecting the surface temperature of the irradiated truck with an infrared thermometer. According to the invention, a pure physical method is adopted to kill the longhorn beetle larvae, thus the method has no pollution to the environment, human and livestock, and the killing rate of the longhorn beetle larvae achieves 100%.

Description

technical field [0001] The invention relates to an agricultural deinsectization method, which is a method for killing beetle larvae with microwaves. Background technique [0002] Beetle is a pest that occurs widely in the world. It is the general name of insects in the family Chrysoopteridae of Coleoptera. It has many types of hosts and extensive damage. For example, forestry, garden trees and fruit trees can be infested by it. And because it has the characteristics of a hidden way of life, few types of natural enemies, and little interference from natural factors, it is very difficult to control, often causing rampant damage and even deforestation. The larvae of longhorn beetles are worm-like, which can drill into the tree and live for more than two years. The newly hatched larvae feed under the bark. As the age increases, they drill into the phloem and xylem to feed and cause damage, destroying the tree's transport tissue. , leading to tree death. There are three main m...

Problems solved by technology

There are three main methods of killing beetle larvae that have been disclosed at present: one is artificial mechanical killing: including hooking larvae, scraping eggs, catching adults and whitening tree trunks, etc. The disadvantage of this method is that the workload is very Large, but the insecticidal effect is not good; another method is the biological insecticide method: such as the larvae and pupae of the longhorn beetle parasitized by Scleroderma guanidei, to protect and attract woodpeckers, and to attract ants to prey on the beetle larvae. This method is being promoted The use is greatly restricted by natural conditions (such as temperature, wind, etc.), the effect is very small, the cost is high, the effect is slow, and it is difficult to promote; the most commonly used method is chemical insecticide: this method requires some highly toxic pesticides : Dimethoate, dichlorvos or omethoate etc. are injected into wormholes to reach the purpose of killing insects. This method is widely used because of its simplicity and ease, and the effect is remarkable. However, this method is very harmful. The resistance to pesticides has led to the continuous increase of the concentration of pesticides, and the pollution of the environment is becoming more and more serious. At the same time, it also seriously endangers the health of humans and animals.
