Problems solved by technology

[0004] In order to solve the problem in the prior art, the artificial breeding of Aphididae often leads to a serious decline in the eclosion rate, egg laying rate, lifespan, activity, etc. of A. The population quality of the artificially bred Aphids persicae is severely reduced, which in turn leads to defects such as the reduction of the control effect of A.

Embodiment 1

[0036] Embodiment one, described in the embodiment of the present invention A Breeding Method for Preventing Population Degeneration of Aphids aphids , the breeding method comprises the following steps:

[0037] S101. Collection of bee species: separately collect the aphids formed by the artificial breeding of Aphids persicae and the ones formed by A. persicae in the wild, and store the collected aphids in test tubes respectively;

[0038] The further described steps of collecting the aphids formed by the artificially bred Aphids persicae are: 1. When the artificially bred Aphis persica forms the aphids, select the aphids with large individual and good gloss, and every 3 One batch is screened every month, and the ratio of the total amount of artificially bred Aphids persicae to the collection of each batch of A. persicae is 1:0.33×10 -4 , that is, in this embodiment, if there are 30 million artificially bred Aphids persicae species in each batch, 1000 will need to be screened...

[0054] Embodiment two, described in the embodiment of the present invention A Breeding Method for Preventing Population Degeneration of Aphids aphids , the breeding method comprises the following steps:

[0055] S101. Collection of bee species: separately collect the aphids formed by the artificial breeding of Aphids persicae and the ones formed by A. persicae in the wild, and store the collected aphids in test tubes respectively;

[0056] The further described steps of collecting the aphids formed by the artificially bred Aphids persicae are: 1. When the artificially bred Aphids persica forms the aphids, select the aphids with large individual and good gloss, and every 5 One batch is screened every month, and the ratio of the total amount of artificially bred Aphids persicae to the collection of each batch of A. persicae is 1:0.50×10 -4 , that is, in this embodiment, if there are 30 million artificially bred Aphids persicae species in each batch, 1500 of them need to be scre...

Embodiment 3

[0072]Embodiment three, a kind of breeding method that prevents the population degradation of Aphidius persicae described in the embodiment of the present invention, this breeding method comprises the following steps:

[0073] S101. Collection of bee species: separately collect the aphids formed by the artificial breeding of Aphids persicae and the ones formed by A. persicae in the wild, and store the collected aphids in test tubes respectively;

[0074] The further described steps of collecting the aphids formed by the artificially bred Aphids persicae are: 1. When the artificially bred Aphis persica forms the aphids, select the aphids with large individual and good gloss, and every 3 -Screen a batch in 6 months, the ratio of the total amount of each batch of artificially bred Aphids persicae to the collection of each batch of A. persicae is 1:0.67×10 -4 , In this embodiment, 2,000 heads were screened from 30 million artificially bred Aphids persicae species; 2. The screened ...

Abstract

The invention discloses a breeding method for preventing aphidius gifuensis species from degrading. The breeding method consists the steps: bee species collection: collecting mummified aphids formed by artificial breeding of aphidius gifuensis and mummified aphids formed by field aphidius gifuensis, and storing the aphidius gifuensis in test tubes; bee species cultivation: placing the test tubes in an arterial climate box for cultivation, purifying the aphidius gifuensis after the mummified aphids in the test tubes are hatched into aphidius gifuensis; aphidius gifuensis mating: mating the artificially bred aphidius gifuensis and the field aphidius gifuensis; breeding: selecting myzus persicae, namely the host of aphidius gifuensis, and making the mated aphidius gifuensis to naturally breed with myzus persicae; when myzus persicae start to form mummified aphids, screening and collecting the mummified aphids and storing the mummified aphids in a storage bottle to obtain the bred mummified aphids. The breeding method mates and cultivates the artificially bred aphidius gifuensis and the field aphidius gifuensis, improves the eclosion rate and the spawning rate of aphidius gifuensis, meanwhile improves the activity of aphidius gifuensis and the quality of the aphidius gifuensis species, and prevents the aphidius gifuensis species from degrading.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a breeding method for preventing the population degradation of Aphidius aphidis. Background technique [0002] Aphids are one of the most destructive pests on the earth. They are seriously harmful to agriculture, forestry and horticulture. They often cluster on leaves, tender stems, flower buds, terminal buds, etc., and suck plant juice through thorns, causing leaves to shrink and Curled and deformed, causing loss of plant nutrition and mechanical damage to organs. In addition, aphids can spread plant virus diseases, and the honeydew they secrete can breed a variety of plant fungi and bacteria and other pathogenic organisms, resulting in the occurrence and prevalence of plant diseases. At the same time, aphids It also has a strong reproductive instinct. In order to control the harm of aphids to plants, after many attempts, it has been concluded that the Aphidida persicae is a kind o...
