Abstract

The invention provides an aphid rearing device. A magnifying glass bottle cap is arranged at the mouth of the bottle body, and the lower part and the upper part of the bottle body are split structures; Evenly distributed stiff aphid grooves are arranged on the aphid groove fixing plate, and the stiff aphid grooves have a flat-bottomed inverted conical structure. The present invention adopts a split-type bottle body, and sets ventilation net windows on the side wall of the bottle body, sets a stiff aphid groove at the bottom of the bottle body, and designs the bottle cap as a magnifying glass. Such a structure can not only avoid the erosion of rainwater, but also facilitate operation. , The split-type bottle body is convenient for the aphid to be retracted, and the magnifying glass bottle cap can observe the hatching of the aphid and the growth and activity of the aphid.

Description

Aphid rearing device

technical field

The invention relates to the technical field of insect feeding, in particular to a feeding device for aphids.

Background technique

Aphidius is an internal parasitic wasp of aphids and is an important natural enemy insect. Important species include Aphidius gifuensis , Diaeretiella rape , Ephedrus plagiator , etc. During the growth process of Aphidus, The eggs will be laid in the body of the host aphid. The larvae are generally 4th instar. The mature larvae mostly cocoon and pupate in the host's husk and enter the pre-pupation stage. The abdomen of the parasitic aphid swells, and the husk turns brown or dark brown. The cortex and epidermis are stiff, but still retain the original shape and appearance of aphids, which are called stiff aphids. The dead aphid is a feature that is easy to identify parasitized by the wasp. When the adult emerges, it bites a small hole in the abdomen of the dead aphid.

At present, Aphidida has been successfully used in production to prevent and control serious aphids. Observing the hatching of aphids and the growth and activity of Aphid has become the main content of research on Aphid. However, the observation devices used at this stage are relatively Extensive, it is easy to cause errors, and it is not convenient for the development of experiments.

Contents of the invention

The purpose of the present invention is to: provide a kind of aphid rearing device, and it has good sealing performance, strong air permeability, low cost, easy to carry, easy to observe, to overcome the deficiencies in the prior art.

The present invention is achieved in the following way: the aphid rearing device comprises a bottle body with a magnifying glass bottle cap at the mouth of the bottle body, a ventilation net window is provided on the side wall of the bottle body, and the bottom and upper parts of the bottle body are split. Structure, the lower part of the bottle body is flexibly connected to the upper part; the bottom of the bottle body is provided with a fixed plate for the worm groove, and evenly distributed worm grooves are arranged on the fixed plate of the worm groove, and the worm groove is a flat-bottomed inverted conical structure.

The aperture of the ventilation net is 55-65 mesh.

The lower part and the upper part of the bottle body are flexibly connected through a card slot.

The lower part and the upper part of the bottle are threaded. This is another connection method, which is also convenient for installation and removal.

Due to the adoption of the above technical scheme, compared with the prior art, the present invention adopts a split-type bottle body, and a ventilating net window is arranged on the side wall of the bottle body, a stiff aphid groove is arranged at the bottom of the bottle body, and the bottle cap is designed as a magnifying glass. , such a structure can not only avoid the erosion of rainwater, but also facilitate operation. Since the aphid tank adopts an inverted conical flat bottom design, by laying filter paper on the flat bottom, the aphid can be implanted and the tank surface is kept dry. Split structure The bottle body is convenient for the aphids to be retracted, and the magnifying glass bottle cap can observe the hatching of the aphids and the growth and activities of the aphids. The invention has the advantages of simple structure, low cost and good use effect.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments, but not as a limitation to the present invention.

Embodiments of the present invention: a dead aphid breeding device, comprising a bottle body 1 is provided with a magnifying glass bottle cap 2 at the bottleneck position of the bottle body 1, and a ventilation net window 3 is provided on the side wall of the bottle body 1, and the ventilation net The aperture of window 3 is 60 mesh. The lower part and the upper part of the bottle body 1 are of a split structure, and the lower part and the upper part of the bottle body 1 are flexibly connected through the card slot 4; The groove fixing plate 6 is provided with evenly distributed stiff aphid grooves 5, and the stiff aphid grooves 5 have a flat-bottomed inverted conical structure.

When adopting the device of this embodiment to raise aphids: separate the upper and lower parts of the bottle body 1, take out the aphid tank 5, cover the flat bottom of the aphid tank 5 with filter paper, place the aphids in the tank, and place the bottle body 1 The upper and lower parts of the upper and lower parts are merged, and the aphids are regularly observed through the magnifying glass bottle cap 2, the eclosion rate of the aphids is observed, and the hatching situation of the aphids and the species and the growth of the aphids are counted.
