the box cover is fixed on the top of the box body;
the support is supported at the bottom of the box body;
the supporting leg is hollow cup-shaped, the opening is upward, and the bottom end of the pillar is fixed in the supporting leg.
The side surface of the box body is provided with an opening and is covered with a gauze, so that parasitic wasps of lepidoptera insect larvae can conveniently enter the box body and parasitize the parasitic wasps on the lepidoptera insect larvae; the side door is arranged on the side face of the box body, so that lepidoptera insect larvae can be conveniently put in and taken out, and if the lepidoptera insect larvae climb out of the box body, the side face is opened to enable the container to catch the larvae hung on the side door, and the larvae are prevented from falling; a plurality of box bodies are arranged in the box body, so that lepidoptera insect larvae can be conveniently dispersed and collected in the box body; the box cover is fixed on the top, has a sun-shading effect, and can avoid the influence of long-time insolation on parasitic wasps of lepidoptera insect larvae; the support legs are hollow cups, the bottom ends of the support posts are fixed in the support legs, and when the insect-proof box is used, insect-proof liquid is injected into the support legs, so that predatory insects such as ants and the like can be prevented from being placed into the box body along the support posts.
Furthermore, the mesh aperture of the gauze is larger than the target lepidoptera insect larva parasitic wasp and smaller than the lepidoptera insect larva, so that the target lepidoptera insect larva parasitic wasp can fly into the box body, and meanwhile, birds are prevented from eating and the lepidoptera insect larva escapes.
In addition, through the high design of box body, can avoid lepidoptera insect larva to climb out of the casing, can show gauze mesh aperture according to lepidoptera insect larva size this moment.
Further, the case cover is made of a light-tight material; the peripheral edge of the box cover protrudes out of the top edge of the box body, so that the sun-shading effect can be improved.
Further, be provided with the mounting groove that is used for fixed pillar in the stabilizer blade to improve the stability of pillar.
A method for collecting parasitic wasps of lepidoptera insect larvae in the field utilizes the device to collect parasitic wasps of lepidoptera insect larvae in the field.
The method comprises the following steps:
1) placing the device in a farmland with target parasitic wasps of lepidoptera insect larvae, placing the lepidoptera insect larvae and artificial larvae feed into each box body in a box body, and closing a side door;
2) filling insect-proof liquid into the support legs to soak the bottom of the support pillar in the insect-proof liquid;
3) and periodically collecting lepidoptera insect larvae in the box body to obtain parasitic wasps of the lepidoptera insect larvae.
Preferably, when collecting the lepidoptera insect larvae, the lepidoptera insect larvae and artificial feed for the larvae are replaced, so that the parasitic wasps of the lepidoptera insect larvae can be continuously collected.
Preferably, the insect-proof solution can be formalin solution with the mass fraction of 20-50%.
Compared with the traditional field artificial capturing method, the structure and the method are simple, the cost is low, the usability is strong, the collecting efficiency is high, and a large amount of parasitic wasps of lepidoptera insect larvae can be collected for a long time. The method is simple, low in cost and high in collection efficiency, and can realize large-scale long-term collection.
