Green branch insect breading device for observing forest tree seed insect life history

Abstract

The invention discloses a green branch insect breading device for observing forest tree seed insect life history and belongs to the forestry insect disease research technology field. The green branch insect breading device comprises a hook, an awning, a water box, a soil box and a gauze and is characterized in that, the soil box is a cylinder, the upper end of the soil box is a rope, the upper end of the rope is provided with the awning, the upper end of the awning is provided with the hook, the lower end of the soil box is provided with a through hole in the cylinder, the through hole is internally equipped with a cotton core, the soil box is internally filled with forest soil, the lower end outer side of the soil box is provided with thread, the upper end of the water box is provided with thread in matching with the soil box, the middle and upper end is provided with a ventilation hole, the water box is internally filled with cleaning water, the water box and the soil box are in thread connection, the outer side of the water box and the soil box is equipped with the gauze, a side end of the gauge is provided with a pull lock, the upper end of the gauze is provided with an upper cable sleeve, and the lower end of the gauze is provided with a lower cable sleeve. According to the green branch insect breading device, and the soil box and the water box are manufactured by a transparent material which can be transparent plastic, or glass and a synthetic glass material. Seed insects are placed in the green branch insect breading device having a survival environment similar to the environment of the seed insects in the wild, quantitative breeding of the seed insects on a tree can be realized, and regular observation about life history can be realized.

Description

technical field [0001] The invention relates to a green branch pest breeding device capable of observing the life history of tree species pests, belonging to the technical field of forestry pest research. Background technique [0002] Observation of the life history of forest tree species pests is generally carried out by catching the insects and placing them in a laboratory container for breeding, and then recording them through observation; Observation is imprecise and its essential properties cannot be determined. At present, the observation of the life history of forest tree pests is mainly carried out on the trees where the insects live, which is a common means to understand the life rules of the target insects. On-site observation has the following shortcomings: (1) Adults are highly active, unable to control their range of activities, and cannot be accurately tracked and observed. (2) The soil around the tree base must be excavated every time to observe the state of...

AI Technical Summary

Problems solved by technology

On-site observation has the following deficiencies: (1) Adults are highly active, unable to control their range of activities, and cannot accurately track and observe

(2) The soil around the tree base must be excavated every time to observe the state of overwintering larvae in the soil, which will affect the growth of trees, which is time-consuming and labor-intensive

(3) It is difficult to observe the state changes of insects in the soil, especially for the biennial insects, the larvae in the soil are multi-generationally superimposed, and it is impossible to quantitatively mark and observe the growth process of each state, and accurately judge the growth process of each insect state. Affects the continuity, completeness, and accuracy of life history observations
