Description

An indoor feeding device for Spodoptera litura larvae

technical field

The utility model relates to an indoor feeding device for Spodoptera litura larvae, which belongs to the technical field of experimental equipment. the

Background technique

Spodoptera litura Fabricius belongs to Lepidoptera, Noctuidae, alias Spodoptera litura, common name night tiger, five-flowered worm, hemp worm, etc., is one of the important agricultural pests worldwide. There are as many as 109 families and 389 species (variants) of host plants of this insect. It is addicted to eating vegetables such as cabbage, Chinese cabbage, and pepper, and food crops such as wheat and rice, and it can also damage economic crops such as tobacco. The larvae eat leaves, flower buds, flowers and fruits. In serious cases, the whole field crops can be eaten up, causing huge losses to agricultural production. Especially Spodoptera litura has the characteristics of concealment, gluttony, and explosiveness. A major potential threat to agricultural production pests.

Scholars at home and abroad have conducted a lot of research in order to deeply study the occurrence and harm rules, biological learning, ecological characteristics, and behavioral rhythms of Spodoptera litura. sex, which requires us to establish a large number of experimental populations indoors. However, if a large number of Spodoptera litura larvae are raised indoors, problems such as poor growth and development and high mortality will always occur. The larvae die after the worm body, and even become extinct; and the younger larvae of Spodoptera litura are more active, like to disperse and feed, and crawl everywhere in indoor breeding, making it difficult to find food, and they are easy to starve to death, and the older larvae have nowhere to hide to avoid light. Moreover, the feeding process goes through four stages of Spodoptera litura eggs, larvae, pupae and adults, the feeding process is complicated, and conventional feeding will consume a lot of manpower and time, which is not conducive to research. the

Contents of the invention

The purpose of the utility model is to provide a device for raising Spodoptera litura larvae indoors in view of the defects of the prior art. The device has a simple and stable structure and is suitable for large-scale rearing of Spodoptera litura larvae indoors to overcome the deficiencies of the prior art. . the

Technical scheme of the utility model

An indoor feeding device for Spodoptera litura larvae, comprising a rearing box with an inverted pyramid structure, a drawer-type metal box is arranged at the bottom of the breeding box, disinfected soil is laid on the drawer-type metal box, filter paper is laid on the soil and placed on the four sides of the breeding box At one corner, the iron gauze is placed in the middle part of the breeding box and clamped tightly with the raising box. Gauze is laid on the mouth of the raising box, and the hollow box cover in the middle presses the gauze and cooperates with the raising box.

In the aforementioned indoor feeding device for Spodoptera litura larvae, the diameter of the iron gauze mesh is 10 mm to 20 mm. the

In the aforementioned indoor Spodoptera litura larva rearing device, the four corners at the bottom of the rearing box are provided with pulleys. the

In the aforementioned indoor Spodoptera litura larva rearing device, a buckle device is provided between the rearing box and the case cover. the

Due to the adoption of the above-mentioned technical scheme, compared with the prior art, the utility model sets the breeding box as an inverted cone structure, and the wire mesh with grids can be put into the breeding box to realize mutual locking, and the wire mesh realizes the alignment of the breeding box. Layered, laying plants on the wire mesh for the feeding of Spodoptera litura larvae, the drawer-type metal box set on the bottom layer is convenient for removing feces and sundries; the metal box is filled with sterilized soil to facilitate pupation of Spodoptera litura larvae; Place the filter paper to facilitate the hiding of Spodoptera litura larvae and remove the dirt on the body wall of the larvae; there is a layer of iron gauze in the box, and the host plant is placed on the grid. The hollow box cover in the middle presses the gauze and cooperates with the breeding box to ensure The air circulation of the rearing box, the utility model utilizes the characteristics that noctuid moth larvae like shade and love to climb. During the feeding process, noctuid moth larvae fall into the soil through the wire mesh to realize pupation. the
