Description

A device for breeding and collecting parasitic insects

technical field

The utility model relates to a device for breeding and collecting insects, in particular to a device for breeding and collecting parasitic insects.

Background technique

Parasitic insects are the natural enemies of many agricultural and forestry pests. Large-scale artificial production of parasitic insects and releasing them to the field to control the occurrence of pests is one of the most effective means of biological control. Parasitic insects lay their eggs inside or outside the pest, and then absorb the body fluid or tissue of the pest through the hatched larvae, thereby finally killing the pest.

The use of parasitic insects to control agricultural and forestry pests can avoid the negative effects of traditional pesticide methods, make the produced crops more natural, and is also conducive to environmental protection. The reproduction and collection of parasitic insects is one of the indispensable links, and it is also the key to whether the parasitic insects can be put into practical application.

For a long time, there have been many technical difficulties in the field application of parasitic insects. The currently used collector mainly uses a glass suction bottle with two straws protruding from the seal. When collecting, one straw is aimed at the insect, and the other is aimed at the mouth. The insects are sucked into the glass suction bottle by people's inhalation. Internally, this collector is inconvenient and unhygienic to use, and its efficiency is extremely low, making it difficult to meet the large demand for insect sources. At the same time, traditional breeding and collection methods also have the following disadvantages:

1. The breeding volume is small. The traditional method of using bottles and cans has a small capacity. The number of breeding is limited by the amount of the host.

2. Uneven parasitism. Due to the uneven distribution of hosts in the breeding space, the search for hosts of parasitic insects is affected by airflow and light, resulting in a low parasitism rate.

3. During the reproduction process using plants as carriers to provide hosts, the shrinkage, mold and rot of plants will lead to the premature death of host insects, which in turn will lead to a decrease in the number of offspring insects (bees) or species cutoff.

4. When collecting, if only relying on the phototaxis and upward characteristics of parasitic insects to let them naturally climb into the collected test tubes and other utensils, the collection speed is slow and the amount is small, and the efficiency is low.

Utility model content

The purpose of the utility model is to provide a device for breeding and collecting parasitic insects.

The device for breeding and collecting parasitic insects provided by the utility model includes a breeding box, a collection container and vacuum obtaining equipment; the breeding box is connected with the collection container through a pipeline, and the collection container is connected with the Vacuum obtaining equipment is connected through pipelines.

In order to facilitate the adjustment of the humidity in the box to ensure the normal growth of plants to prevent premature rot and improve collection efficiency, the top surface of the breeding box can be designed as a detachable net cover, and then cover the top of the net cover There are removable sealing caps. Wherein, the mesh cover may specifically be a gauze cover; the sealing cover may specifically be a transparent inverted funnel-shaped cover.

In the process of breeding parasitic insects, when the humidity in the box is low, cover the sealing cover above the net cover to prevent moisture loss in the box; when the humidity in the box is high, then The sealing cover was removed, leaving only the mesh cover for ventilation. The net cover ensures the fresh air in the box, and also avoids condensation or even water droplets on the inner wall of the box due to the evaporation of water. Since parasitic insects do not fly during the reproduction process and cannot escape from the holes of the net cover, there is no special requirement for the aperture size of the net cover at this stage.

When collecting parasitic insects, the mesh covers with different apertures can be replaced according to the size of the insects to be collected. The apertures do not allow the passage of host insects. Put on a black cloth cover, and connect an external light source on the top of the box to maximize the phototaxis and upward properties of the parasitic insects, and collect the insects in the cavity surrounded by the mesh cover and the sealing cover. The net cover removes other impurities such as plant leaves and host insects. At the same time, the area of the net cover is relatively large, which can allow more parasitic insects to pass through the net cover quickly, thereby improving the collection efficiency.

The pipeline connecting the breeding box and the collection container is opened in the cavity of the sealing cover. Specifically, a switching tube may be provided on the top of the sealing cover, and the pipeline is connected to the switching tube, thereby communicating with the cavity of the sealing cover. Wherein, the switching tube may specifically be a tube that is thicker at the bottom and thinner at the top, and its diameter may be adjusted according to actual needs.

In order to prevent premature wilting and drying of host plants and prolong the parasitic time of parasitic insects, a drawable water tank can be set at the bottom of the breeding box, and a removable partition with holes can be set above the water tank. The board is opposite to it, and in order to facilitate pulling, hand buckles can be set on both sides of the sink.

In practical application, the culture method can be selected according to the different characteristics of the host plant, preferably hydroponics. If the host plant is a hydroponic plant, you can fill the tank with culture solution or water, and then insert the plant or branch into the tank through the hole on the partition, or put the plant in the seedling cup and then pass it through the partition Insert the holes into the water tank so that the plants can absorb nutrients continuously and survive for a long time without drying out; if fresh leaves of plants are used as host plants, first put a layer of water-absorbing material (such as a 1-2cm thick sponge) on the partition ) or only place water-absorbing material at the hole of the partition, and extend a line of water-absorbing material from the bottom end of the water-absorbing material at the hole, so that it passes through the end of the porous partition and immerses it in the water tank, or dips one end of the water-absorbing material In the tank, the fresh plant leaves are then placed on the perforated partition, so that the water-absorbing material draws the water up through the siphon effect, thereby ensuring that the plants continuously absorb water. Moreover, the nutrient solution or water in the water tank can be continuously replenished during the cultivating process. The setting of water tanks and partitions enables the plants to absorb water continuously and will not die quickly, so that the host insects can continue to feed and develop in the leaves until the host insects are parasitized and develop into pupae or adult stages, which are parasitic insects Sufficient time is provided for the parasitism of host insects.

In order to make the insects parasitize uniformly, light sources can be installed in the breeding box, such as adjustable fluorescent tubes, etc., specifically at the four corners of the breeding box, so that by adjusting the light source, the light received by each part of the box can be uniform, ensuring The distribution and movement direction of parasitic insects in various parts have no concentration points, and will not cause clustering. In order to further evenly parasitize insects, glass can also be used to make breeding boxes. Coupled with the design of the net cover, the ventilation and light conditions of the plant leaves are the same, so that the probability of parasitic insects finding each host insect is the same, and it is rare for some hosts to hide and miss parasitism.

The design of the adjustable light source can also give different degrees of light according to the different habits of the breeding parasitic insects, and the use is more flexible.

In order to facilitate picking and placing plants or cleaning up garbage in the box, a switchable door can be set on one side of the breeding box.

For the convenience of picking up insects in the box, one side of the breeding box can be provided with a through hole, and the hole is covered with a switchable net door.

The above-mentioned collection container can be a jar or a self-made bottle.

In practical application, the bottle mouth is closed, such as can be closed with a rubber stopper, and a hole can be set on the stopper for the pipeline to pass through and then be connected with the breeding box and the vacuum obtaining equipment.

The pipeline connecting the collection container and the vacuum obtaining device is sealed with a mesh at one end of the collection container; the aperture of the mesh does not allow the insects to be collected to pass through, so as to prevent insects from being sucked into the pipeline middle.

The above-mentioned vacuum obtaining equipment can specifically be a vacuum pump or an axial flow exhaust fan, etc., and the vacuum obtaining equipment can be used for suction to form a negative pressure environment in the collection container, making it easier for insects to fall into the collection container from the breeding box, and the work efficiency is high. , safe, hygienic and convenient.

For the convenience of carrying, the collection container, the vacuum obtaining equipment and pipelines can also be assembled in a box to form a collection box.

The shapes of the above-mentioned breeding box and collection box can be various, such as cuboid, cube, sphere, etc., which can be selected according to actual needs.

The device provided by the utility model has the advantage of large breeding capacity, for example, a breeding box with a volume of 50×30×45cm can breed more than 2500-5000 parasitic insects at a time; the utility model device also has the advantage of high parasitic efficiency, For example, by adjusting the humidity in the breeding box and the water supply of the water tank, the leaves of the host plant are not easy to dry out, thus providing sufficient time for the parasitic insects to parasitize, and by setting the light source to make the light in the box uniform and sufficient, so that the parasitic insects can parasitize evenly ; In addition, the collection structure in the device also has the advantages of high collection efficiency, safety, sanitation and convenience. Therefore, the device of the utility model is simple and practical, and is suitable for feeding, breeding, collecting and releasing various parasitic insects.
