Description

A simple device for collecting and releasing aphid-eating gall midge pupae

technical field

The utility model relates to the technical field of collecting aphid-eating gall midge pupae, in particular to a simple collection and releasing device for aphid-eating gall midge pupae.

Background technique

Aphidoletes aphidimyza is distributed all over the world, and there are a large number of local strains of Aphidoletes aphidimyza in Guizhou, which can prey on a variety of aphids and is an effective predatory natural enemy. Therefore, domestic and foreign studies on the biological control of aphid gall midges are relatively extensive, especially for the control of aphids in greenhouses. The breeding, batch breeding and release of aphid gall midges are the basis of natural biological control. In the batch breeding process, it is also a key step to effectively collect the mature larvae of the aphid gall midge. The current method is to wait for the mature larvae to automatically bounce into the water, and then collect the mature larvae that bounce into the water within a certain period of time. Mature larvae. However, in the process of large-scale reproduction, the number of mature larvae is relatively large. To obtain a large number of pupae of aphid gall midges for release in the field, it takes a lot of time to adopt the old collection method, and it needs to be collected within a certain period of time to avoid Causes the death of mature larvae in water.

Therefore, designing a simple and effective device to obtain the pupae released by the philodendron can not only facilitate and simplify the reproduction process, save time and effort, but also ensure the high survival rate of the mature larvae of the philodendron. Pupation occurs, as well as higher eclosion uniformity and survival rates.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

In describing the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", The orientation or positional relationship indicated by "outside" is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation , are constructed and operated in a specific orientation and therefore cannot be construed as limiting the invention.

Referring to Figures 1-3, a simple device for collecting and releasing aphid-eating gall midge pupae comprises a box body 3, a plurality of absorbent cottons 5 are tiled on the inner bottom of the box body 3, and a barbed wire frame 4 is placed inside the box body 3, The top of the box body 3 is provided with a box cover 2, the center of the box cover 2 is provided with an opening 1, and the top of the box cover 2 is located at the corresponding position of the opening 1 and pasted with a gauze 6, and the mesh number of the gauze 6 can be adjusted according to the needs. Make a selection.

In the utility model, the box body 3 and the box cover 2 are made of transparent plastic material, which is convenient for observing the inside of the box body 3, and the thickness of the absorbent cotton 5 is about 0.5-2 cm, which provides an environment for pupation for mature larvae of aphid-eating gall midges , the center of both sides of the bottom of the box cover 2 is provided with a first magnet 7, and the edges of both sides above the box body 3 are provided with a second magnet 8 corresponding to the first magnet 7, so as to ensure the connection between the box cover 2 and the box body 3 The stability between the first iron magnet 7 and the second iron magnet 8 is magnetically connected, and it is more convenient to open. The wire mesh frame 4 is composed of a wire mesh and four legs, and the four legs are fixed at the four corners of the bottom of the wire mesh. The inner bottom of the body 3 is provided with grooves corresponding to the bottom ends of the feet to prevent the wire mesh frame 4 from sliding inside the box body 3. What needs to be explained here is that when taking the wire mesh frame 4, attention should be paid to whether the feet will press the aphid gall Mosquito mature larvae.

In the utility model, at first spread the absorbent cotton 5 on the inner bottom of the box body 3, spray an appropriate amount of clear water to moisten the absorbent cotton 5, put the wire rack 4, and place the host with the mature larvae of aphid-eating gall midges and their prey aphids Plants are spread on the wire rack 4, close the lid 2, take out the host plant after one to two days, and put the absorbent cotton 5 with pupae on the wire rack 4, spray water on the absorbent cotton 5 to keep the absorbent cotton 5 moist until aphids eat Eclosion of gall midges can ensure the survival rate of gall midges after eclosion, and then release the eclosion adults into the oviposition chamber or the test field. Wherein the placement position of the absorbent cotton 5 has two different effects: the one is to spread the absorbent cotton 5 on the inner bottom of the box body 3, put the wire rack 4, and place the host plant with mature larvae of the aphid gall midge on the wire rack 4, play the collection effect of the mature larvae of the aphid gall midge; the second is after the mature larvae of the aphid gall midge have pupated in the absorbent cotton 5, the absorbent cotton 5 is placed on the iron wire frame 4 to make the aphid gall midge mature. Mosquito can move freely after eclosion, avoids being positioned at the bottom of absorbent cotton 5 after eclosion and causes unable to fly out and dies.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
