Problems solved by technology

[0003] At present, the artificial reproduction process of Aphididae is relatively cumbersome, and it needs to go through the following processes: breeding aphid host plants, multiplying aphids, inoculating Aphidia, expanding Aphid, collecting Aphid, aphid and Aphid conservation and other procedures, the process involves many links, requires a lot of manpower and material resources, and needs to occupy a large area of ​​breeding grounds, and the overall cost is relatively high
Moreover, since there is no artificial feed specially used for the reproduction of Aphids persicae, the effect of artificial reproduction is not ideal

Embodiment 1

[0024] Embodiment 1: the selection of nutritional composition components

[0025] According to the results of the analysis of the nutritional composition of Aphids, combined with the nutritional elements necessary for the growth and development of insects, the applicant selected the composition and ratio of the components of the nutritional composition, and determined the optimal one according to the eclosion rate of A. Components and ratios.

[0026] This embodiment lists representative three groups of nutrient combinations in the screening process for illustration:

[0027] The first group: egg yolk 35%, skimmed milk 35%, sucrose 10%, inorganic salt 1%, multivitamin 2%, compound amino acid 10%, methyl p-hydroxybenzoate 0.1%, agar 0.2%, distilled water 6.7%. The nutrient composition of this example was used to breed the Aphids aphidis, and the eclosion rate was obtained by an average of 42% per bee card.

[0028] The second group: 25% of tube aphid homogenate, 25% of egg yo...

Embodiment 2

[0035] Embodiment 2: the preparation of artificial aphid

[0036] Melt the agar used for the preparation of the medium with hot water and set aside; add the components of the Aphidius spp. , and add 250-350 units / ml of penicillin; after mixing evenly, use parafilm film as coating material, and make artificial aphids with a diameter of 1.5-2.0mm on a honeycomb machine.

Embodiment 3

[0037] Embodiment 3: the selection of laying eggs attractant component

[0038] In order to improve the egg-laying rate of Aphididae on artificial aphids, the applicant selected the composition and ratio of the egg-laying attractant of A. Compare.

[0039] The first group: Aphids tabaci Nutrient formula: 30% of Aphis persicae homogenate, 20% of egg yolk, 20% of skimmed milk, 10% of sucrose, 1% of inorganic salt, 2% of multivitamins, 10% of compound amino acids, p-hydroxy Methyl benzoate 0.1%, agar 0.2%, distilled water 6.7%.

[0040] After the artificial aphids are prepared by the above formula, the following oviposition attractants are sprayed on the surface of the artificial aphids: 10% sucrose, 10% compound amino acids, 1% nepetalol, 1% nepetalactone, trans-β-farnesene 1%, distilled water 77%.

[0041] Using the nutritional composition of this example and the oviposition attractant to breed the Aphids persicae, the average eclosion rate per bee card was 67%.

[0042] Th...

Abstract

The invention provides artificial aphids for aphidius gifuensis ashmead propagation. The nutritional compositions for preparing artificial aphids include the following components in percent concentration by mass: 30 percent of aphid homogenate, 20 percent of egg yolk, 20 percent of skim milk, 10 percent of sucrose, 1 percent of inorganic salt solution, 2 percent of complex vitamin solution, 10 percent of complex amino acid solution, 0.1 percent of methyl p-hydroxybenzoate, 0.2 percent of agar and 6.7 percent of distilled water. The artificial aphids can effectively supply nutrition essential to development of aphidius gifuensis ashmead, and an attractant for oviposition of aphidius gifuensis ashmead is applied to the surface of artificial aphids, so that the survival rate, parasitism rate and eclosion rate of aphidius gifuensis ashmead can meet actual requirement. The artificial aphids can be used for solving defects of complex process, large occupation space, high cost and the like of a traditional propagation method, and the propagated aphidius gifuensis ashmead can be easily collected, stored and released; and the artificial aphids have the advantages of wide raw material source, simple preparation process, and is suitable for large-scale popularization.

Description

technical field [0001] The invention belongs to the technical field of insect reproduction, and in particular relates to an artificial aphid used for the reproduction of Aphidius aphidii. Background technique [0002] Aphids persicae is an important parasitic wasp of aphids. It is distributed in the north and south of my country. It has a strong natural control over the host aphids. The main parasitic objects include aphids such as aphids, two-handed aphids, and radish aphids. In tobacco fields, the parasitism rate of Aphids persicae to A. persica is usually 20%-60%. Aphids aphids has a wide application prospect in biological control and has important economic value. It has always been the object of close attention of biological control workers in my country. At present, our country has formed a set of relatively complete artificial propagation technology of Aphids persicae, and it has been widely used in the control of aphids in tobacco and other crops. [0003] At presen...
