Description

A green branch insect breeding device capable of observing the life history of forest tree pests

technical field

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

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 overwintering larvae in the soil, which will affect the growth of trees, which is time-consuming and laborious. (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 superimposed by multiple generations, 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. The time elapsed by age affects the continuity, completeness and accuracy of life history observation.

Contents of the invention

In order to overcome the above disadvantages, the present invention provides a green branch pest breeding device that can observe the life history of forest tree pests. The device can not only observe the activities of adult insects feeding, mating, and laying eggs, but also regularly check the growth of larvae in the soil. , pupation, eclosion, etc., suitable for observation of the life history of tree species pests.

The technical solution adopted by the present invention to solve its technical problems is: comprising hook, canopy, water box, soil box, gauze, its structure is: the soil box is cylindrical, and its upper end is provided with hanging rope, and the upper end of hanging rope There is a canopy, the upper end of the canopy is provided with a hook, the lower end of the soil box is provided with a through hole in the cylinder, and a cotton core is installed in the through hole, and the soil box is filled with understory soil; the outer side of the lower end of the soil box is provided with threads; the upper end of the water box There is a thread matched with the soil box, there is a vent hole in the middle and upper end, and the water box is filled with clean water; after the water box and the soil box are screwed together, a gauze is installed on the outside, the side end of the gauze is provided with a zipper, and the top of the gauze is equipped with an upper The noose is provided with a lower noose at the lower end.

Described earth box and water box are made of transparent material, can use transparent plastic, glass, plexiglass material.

The beneficial effects of the present invention are: the planting pests are put into the device, and the living environment of the device is similar to that of the planting pests, so that the quantitative feeding of the planting pests can be realized, and the life history can be observed regularly, without affecting the life rules of the planting pests, which is convenient. Observation shows that the structure is simple, the design is reasonable, easy to operate, economical and practical. It provides an applicable field observation device for the study of the life history of seed pests.

detailed description

As shown in Figure 1, a kind of green branch pest breeding device that can observe the life history of forest tree species pests comprises hook, canopy, water box, soil box, gauze net, and its structure is: soil box 4 is cylindrical, Its upper end is provided with lanyard 6, and the upper end of lanyard 6 is provided with canopy 7, and canopy 7 upper end is provided with hook 8, and soil box 4 lower end cylinders are provided with through hole 2, and cotton core 12 is installed in through hole 2. Undergrowth soil 5 is housed in the soil box 4; The outside of the soil box 4 lower end is provided with thread 3; Clear water 14; Water box 1 is provided with gauze 13 outside after being screwed with earth box 4, and gauze 13 side ends are provided with slide lock 10, and gauze 13 upper ends are provided with last cable cover 9, and lower end is provided with following cable cover 15.

Described soil box 4 and water box 1 are made of transparent material, can use transparent plastics, glass, plexiglass material.

The use process of this device is: understory soil 5 is housed in the soil box 4, clear water 14 is housed in the water box 1, a water diversion cotton core 12 is provided in the through hole 2 of the soil box 4, and the lower end of the water diversion cotton core 12 is at the bottom of the water box 1, The upper end is clamped in the soil 5 under the forest, and is connected together by threads; the hook 8 is hung on the branch, and the branches and leaves are wrapped on the upper end of the soil box 4, and the upper cable sleeve 9 on the upper end of the gauze net 13 is tightened, and the lower cable sleeve 15 is tightened. Gauze 13 is covered in the outside of water box 1 and soil box 4, is closed by zipper; The humidity of soil can be guaranteed by putting plant pests into the soil, simulating living environment, and beneficial to observation.

Put the soil box into the undergrowth soil, insert the cotton core into the water box to form a whole, hang it on the branches in the nylon mesh bag, and install the rainproof cap. Used to observe the life history of seed pests.

In autumn, before the larvae go into the soil to overwinter, the seeds are collected, and a wooden box with a depth of 30 cm is buried in the forest. Nylon nets are spread in the box to prevent other insects from entering. Wrap tightly with nylon net to allow the larvae to burrow into the soil and overwinter.

In the spring of the following year, take out the box, screen the larvae with normal growth and group them quantitatively by age, put the larvae of the same age into the same insect culture box, mark them and hang them on the branches, and observe, measure and record the growth and eclosion of the larvae regularly.

After the adults emerged, regularly observe and record the mating, egg laying and hatching conditions of the adults in the cage. When the leaves in the cage are insufficient, new branches and leaves outside the cage are collected to supplement, and the thin branches and leaves are inserted into the water box from the nozzle to keep fresh, so as to ensure that the food in the cage is fresh and sufficient, and the insects do not escape.
