Forest pest outbreak risk prediction method and device

Abstract

The invention discloses a forest pest outbreak risk prediction method and device, the device comprises a collection mechanism and a fixing mechanism detachably mounted on the collection mechanism, and the collection mechanism comprises a capturing mechanism for capturing pests and an inducing mechanism detachably mounted at the top of the capturing mechanism for inducing the pests; the catching mechanism comprises a catching barrel, a conical cover is arranged at the top end of the catching barrel, a circular groove communicated with the catching barrel is formed in the center of the top end of the conical cover, a funnel is fixedly arranged in the circular groove, and the inducing mechanism comprises a rainproof cover. According to the forest pest outbreak risk prediction method and device, pest trapping and sampling can be achieved, time and labor are saved, the sampling efficiency is greatly improved, and pest classification is completed, so that the situation that pests of different body types die due to biting is reduced, the survival rate of the pests is greatly increased, and the survival rate of the pests is increased. And the outbreak risk of diseases and insect pests can be quickly predicted.

Description

technical field [0001] The invention belongs to the technical field of forest disease and insect pest control, and in particular relates to a method and device for forest disease and insect outbreak risk prediction. Background technique [0002] Forest is a biological community with woody plants as the main body. It is a whole ecosystem formed by concentrated trees, other plants, animals, microorganisms and soil, which are interdependent and restrictive, and interact with the environment. Descent, fauna, regulation of hydrological turbulence and soil consolidation play an important role and is one of the most important habitats in Earth's biosphere, known as the "lungs of the earth". [0003] At present, in the process of predicting the risk of outbreaks of pests and diseases in the forest, a sampling device for pests and diseases needs to be used to obtain the number and types of pests in the forest area. [0004] In the prior art, most of the sampling devices used in the ...

AI Technical Summary

Problems solved by technology

[0004] However, in the prior art, most of the sampling devices used in the method for predicting the risk of pest outbreaks are sampling nets, and the staff use the sampling nets to sample around the trees where pests occur. Sampling pests in this way is time-consuming and laborious, and the efficiency is relatively low. It is impossible to quickly predict the risk of pest outbreaks, and during the sampling process, it is easy to cause damage to pests, resulting in a decrease in the survival rate of pests, affecting the staff's subsequent detection of pests, and easily affecting the prediction results of pest outbreak risks
