Problems solved by technology

[0004] In the process of artificial reproduction, aphid gall midges pupate in a specific medium. Because the color and size are very close to those of sand and vermiculite, it is difficult to separate the pure pupae of aphid gall midges, and it is not easy to obtain pure pupae of aphid gall midges.

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the embodiments and the accompanying drawings. The protection scope of the present invention is not limited to the embodiments, and any changes made by those skilled in the art within the scope defined in the claims also belong to the protection scope of the present invention.

[0013] (1) Making fresh-keeping boxes

[0014] ⑴ Use a round plastic box as a fresh-keeping box, such as figure 1 Shown, comprise box body 8, gauze 1 and lid 4, the diameter of fresh-keeping box is 9cm, and height is 6cm. Cover the fresh-keeping box with sand, the amount of sand is 180ml, and the size of the sand grains is sand that passes through a 30-mesh sieve, and the sand should be paved flat. The mesh aperture of gauze 1 is 100 orders, and the aperture 3 on the lid 4 is 0.5cm.

[0015] (2) Add 50-60ml of water into the sand layer 7 with a rubber dropper. When adding water, the action should be slow and the water...

Abstract

The invention relates to a method for obtaining pure pupae of Aphidoletes aphidimyzaes. The method comprises the following process: collecting mature Aphidoletes aphidimyza larvae, placing the matureAphidoletes aphidimyza larvae in a crisper for cultivation, wherein sand is laid in the crisper, water is added for moisturizing the sand layer before use, lower-layer filter paper is laid on the sandlayer, the lower-layer filter paper is stuck with a masking tape, and pleated filter paper is placed on the lower-layer filter paper strips; putting the mature larvae on the pleated filter paper strips, covering the mature larvae by upper-layer filter paper; and covering the box mouth with a gauze, and performing covering with the box cover. The pure pupae of Aphidoletes aphidimyzaes can be obtained after placing for 4-5 days at a temperature of 20-25 DEG C under a raltivehumidity of 80-90%. In the method, the crisper is used for cultivating the pure pupae of Aphidoletes aphidimyzaes, optimizes growth environment and conditions of Aphidoletes aphidimyzaes, solves the problem of separation difficulty of the pure pupae of Aphidoletes aphidimyzaes, and improves the obtaining efficiency and the survival rate of the pure pupae of Aphidoletes aphidimyzaes.

Description

technical field [0001] The invention belongs to the technical field of biological control of agricultural pests, and in particular relates to a method for obtaining pure pupae of aphid-eating gall midges. Background technique [0002] Aphid gall midges are predatory natural enemies of many aphid species in greenhouses. Nowadays, controlling aphids by artificially breeding and releasing them into the field is one of the important measures to change the current control mode mainly controlled by chemical pesticides, and it is of great significance. [0003] In nature, aphid gall midges survive the winter in the soil in the form of pupae. Artificial mass breeding of aphid gall midges collects mature larvae and puts them in a specific medium (sand, vermiculite, sand). Pupate in the medium, and wait 8 to 9 days for aphid gall midges to emerge to obtain adults for application. [0004] In the process of artificial reproduction, the aphid gall midge pupates in a specific medium. B...
