Problems solved by technology

[0007] In the practice of propagating Aphids persicae, we found that the above-mentioned techniques are not suitable for the northern regions of my country. The main manifestations are: first, the tobacco growth cycle is long, and it often takes more than 90 days from sowing to inoculation of aphids, requiring a lot of manpower and material resources ; Second, the growth of tobacco requires a large space, and a single tobacco plant can grow to a height of 2 meters. To arrange tobacco cultivation with a spacing of 1*1 meter, a large area of ​​propagation site is required; third, tobacco leaves are sticky, It is not conducive to the collection of parasitic bees; fourth, the collection of bees is not conducive to product storage and transportation

Embodiment 1

[0037] Embodiment 1, the comparison test of different hosts multiplying Aphidius mignina

[0038] In this example, Myzus persicae, Schizaphisgraminum, Lipaphis erysimi and Aphis glycines were respectively used as hosts to propagate Aphis persicae. The differences in parasitoid rate, eclosion rate, developmental duration, individual size and sex ratio of parasitoids obtained from different hosts were analyzed and compared.

[0039] See Table 1 for the age, individual size and other indicators of the four hosts

[0040] Table 1 The age and body size of four kinds of tested hosts

[0041]

[0042] Note: The four species of aphids in the table were raised under the conditions of 25±1°C, 70±10% relative humidity, and 16h / d light; the crop species were marked after the host plant; the data in the table were mean ± standard error; "Body length" is the length from the forehead of the aphid to the end of the abdomen, and 20 aphids of each kind are measured; "Body width" is the max...

Embodiment 2

[0069] Embodiment 2, utilize the method for propagating and propagating Aphidia persicae

[0070] 1. Cultivation of seedlings

[0071] 1. Selection of seedling varieties

[0072] The seedlings are wheat, the variety is Shixin 828, and the seeds with positive color, large grains, plump, regular shape and uniform texture are selected.

[0073] 2. Rapid propagation of seedlings

[0074] Rapid propagation conditions: temperature 27±1°C, relative humidity 65%-70%, photoperiod L:D=14h:10h.

[0075] 1) Germination and sowing: In a closed and isolated seedling cultivation room, put vermiculite in a plastic box with a length, width and height of 30cm×20cm×12cm, which is about 2 / 3 of the box volume, and then sprinkle wheat seeds into the leech In the stone (pay attention to spread evenly), finally cover a layer of vermiculite on the wheat seeds (just submerged the wheat grains) and moisten the vermiculite evenly (avoid too much water to prevent the wheat grains from rotting).

Abstract

The invention discloses a method for expanding propagation of aphidius gifuensises. The method comprises the following steps: inoculating to-be-spawned aphidius gifuensis queen bees to plant seedlings with the schizaphis graminums to conduct bee breeding, and collecting the aphidius gifuensises to achieve the expanding propagation. According to the method, the schizaphis graminums are used as bee breeding hosts, technical links of best inoculating ratio, inoculating time and aphidius gifuensis collection are adopted, and a parasitic wasp expanding propagation technique which is high-efficiency, economic and simple is formed through repeated explorations and improvements, the expanding propagation of a large number of aphidius gifuensises can be achieved rapidly, and the purpose of biological prevention and control for injurious insects is achieved.

Description

technical field [0001] The invention belongs to the field of biological technology, and relates to a method for multiplying the Aphididae, in particular to a method for multiplying the Aphididae with the digem aphid as a host. Background technique [0002] Aphids are one of the most destructive pests on earth. There are about 4,400 species of aphids that have been found in 10 families, of which about 250 species are serious pests for agriculture, forestry and horticulture. Often clustered in leaves, tender stems, flower buds, terminal buds, etc., sucking plant juice through thorns, causing leaves to shrink, curl, and deform, causing plant nutrition loss and mechanical damage to organs. In addition, aphids can spread plant virus diseases, The honeydew it secretes can breed a variety of plant fungi and bacteria and other pathogenic organisms, causing the occurrence and prevalence of plant diseases. Aphids also have a very strong reproductive instinct. Some species of aphids ...
