Description

A device for mass breeding of looper larvae

technical field

The utility model belongs to the technical field of insect feeding devices, in particular to a device for feeding large quantities of inchworm larvae.

Background technique

Inchworm is the main pest on many plants. Its larvae consume a lot of food and are highly active, often breaking out into disasters. Inchworms on tea trees, such as tea inchworms, gray tea inchworms, and tung leaf inchworms, are the main control targets in tea gardens. Mass breeding of inchworm larvae is the basis for insect virus production, drug activity determination and various experimental studies.

Cutting breeding is a commonly used method for mass breeding of woody plant pests. Cutting breeding has the advantages of less labor input and low probability of healthy insects being infected with pathogens. But still do not have special cutting cutting raising device at present, usually carry out according to the existing utensil at hand, and what have uses plastic barrel, and what has uses plastic bottle, and what has uses glass bottle. Glass jars are often used in large-scale breeding of tea geometrid and other larvae. The method is to insert tea branches into a 500mL jar for hydroponics, and then connect the larvae to the tea branches and allow them to eat until the leaves are about to be eaten. When it is exhausted, put 1-2 bottles of fresh tea branches cultivated in water next to the bottle. The disadvantages of the above method are: (1) in the process of mass breeding, dozens of vases are often placed on the ground at the same time, it is very inconvenient to add water to the bottles, and it is easy to wet the insects and leaves, and the vases are easy to overturn at the same time; 2) Since the added feed is to put 1-2 bottles of hydroponic fresh tea branches next to the bottle, the time for the larvae to climb to the fresh tea branches is late or early, resulting in extremely irregular development of larvae in the later stage of rearing, and the size of the larvae The difference is large, which affects the yield of virus proliferation and the accuracy of drug activity determination; (3) When most of the tea leaves in the bottle are almost eaten up, it is also very inconvenient when the feed needs to be replaced. The original tea branch must be pulled out. Catch the worms on the original tea branch to the new tea branch, the workload is heavy and the efficiency is low.

Utility model content

Aiming at the problems existing in the prior art, the purpose of this utility model is to design and provide a technical scheme of a device for feeding large quantities of inchworm larvae. The device is simple in structure, easy to use, high in working efficiency and good in feeding effect.

The device for raising large quantities of inchworm larvae includes a box body and a box cover, and is characterized in that a main hole is arranged in the center of the box cover, and a main hole cover is arranged on the main hole, and the main hole cover is arranged on the main hole. A group of auxiliary holes is evenly arranged around the hole, the auxiliary hole cover is arranged on the auxiliary hole, the water injection hole is arranged outside the auxiliary hole, and the water injection pipe is arranged in the water injection hole.

The device for raising large quantities of inchworm larvae is characterized in that the edge of the box cover is provided with a cover button that can be fastened with the box body.

The device for raising large quantities of inchworm larvae is characterized in that four auxiliary holes are uniformly arranged around the main hole.

The device for raising large quantities of geometrid larvae is characterized in that the distance between the auxiliary holes is at least 6cm.

The device for raising a large number of looper larvae is characterized in that the height of the water injection pipe is equal to or slightly higher than the height of the tea branches inserted in the main hole and the auxiliary hole.

The device for raising large quantities of inchworm larvae is characterized in that the box body is a cuboid or cube structure.

The above-mentioned device for feeding a large number of inchworm larvae has the following advantages: (1) It is very convenient to add water to the box body. Since the water injection pipe is at the same height as the tea branch or slightly higher than the tea branch, it is very convenient to add water. In addition, since the box body is a tetrahedron, it is very stable after adding water and will not overturn; (2) It is convenient to add and replace tea branches, and the larvae grow uniformly. When using, first open the hole cover of the main hole, insert the tea branch, close the hole cover of the auxiliary hole, connect the larvae, wait until the leaves are almost eaten up, when it is necessary to add tea branches, open the auxiliary hole, insert fresh tea branches, and use The fresh tea branches and the tea branches in the main hole are in contact with each other, and the inchworms will quickly transfer to the fresh tea branches to feed, avoiding the inconsistent development of the inchworms due to uneven feeding; (3) The size of the device is moderate, and it is flexible to use It is changeable, and can be arranged horizontally and vertically on the breeding platform or on the ground for mass breeding of insects, and can also be put into insect cages alone for species conservation and breeding.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in FIG. 1 , a device for raising large quantities of inchworm larvae includes a box body 1 and a box cover 2 matched with the box body 1 . The box body 1 is preferably a cuboid or a cube structure, which has good stability. The edge of the box cover 2 is provided with a cover button 201 to facilitate the fastening of the box cover 2 and the box body 1 . A main hole 3 is arranged in the center of the lid 2, and a main hole cover 4 is arranged on the main hole 3, and a group of auxiliary holes 5 are uniformly arranged around the main hole 3, and an auxiliary hole cover 6 is arranged on the auxiliary hole 5. As a preferred structure, four auxiliary holes 5 are evenly arranged around the main hole 3, and the four auxiliary holes 5 are symmetrically arranged around the main hole 3 with the main hole 3 as the center, and the distance between the auxiliary holes 5 is at least 6 cm. A water injection hole 7 is arranged outside the auxiliary hole 5, and a water injection pipe 8 is arranged in the water injection hole 7. As a preferred structure, the water injection hole 7 can be arranged at the upper left corner, the upper right corner, the lower left corner or the lower right corner of the lid 2 . The height of the water injection pipe 8 is equal to or slightly higher than the tea branch height inserted in the main hole 3 and the auxiliary hole 5, which is convenient for adding water.

In actual application, the size of the box body 1 can be set to be 24 cm long, 16 cm wide, and 14 cm high or 16 cm long, 16 cm wide, and 14 cm high. The aperture of the main hole 3 on the lid 2 is set to 3 cm, the aperture of the auxiliary hole 5 is set to 2-2.5 cm, and the aperture of the water injection hole 7 is set to 0.8-1.0 cm. Water injection pipe 8 is long and is set to 30cm. The box body 1 is made of transparent plastic or glass, and the box cover 2 and the water injection pipe are all made of plastic.

The using method of this insect breeding device is as follows:

First fill the box body 1 with water, cover the box cover 2, insert the water injection pipe 8, then open the main hole cover 4, insert fresh tea branches into the main hole 3, and use a little cotton to block the gap between the tea branches , Then connect the inchworm larvae to the tea shoots and let them feed. When the larvae have finished eating the tea leaves, open the auxiliary hole cover 6, take fresh tea branches and insert them into the auxiliary holes 5, so that the fresh tea branches and the tea branches in the main hole 4 are in contact with each other, so that the larvae can be transferred to fresh tea branches as soon as possible superior. Depending on the water level situation in the box body 1 in the raising process, add water in the box body by the water injection pipe 8 in good time. When the fresh tea sticks in the auxiliary hole 5 are almost eaten up, pull out the residual tea sticks in the main hole 3 and replace them with fresh tea sticks until the larvae pupate. Generally, only one replacement is required in the main hole to complete one generation. After all the larvae have pupated, collect the pupae intensively. The device was cleaned and disinfected until the next batch of larvae was reared.
