Technical Field

The invention relates to the technical field of biology, in particular to a nutritional supplement for prolonging survival time of adult aphidius gifuensis ashmeads.

Background

Aphidius gifuensis Ashmead belongs to the genus Aphidius in the family Hymenoptera (Hymenoptera) Aphidiidae (aphiadidae), and is distributed abroad in japan, korean and hawaii islands in eastern asia; the aphid is distributed in Jilin, Liaoning, Shaanxi, Shandong, Henan, Jiangsu, Anhui, Zhejiang, Fujian, Taiwan, Guangdong, Yunnan and other provinces domestically, and is the dominant natural enemy of the tobacco aphid mainly in the tobacco areas of the eastern and southern provinces of China. Besides Myzus persicae (Sulzer), aphidius rapamissicae (Linnaeus), Lipaphiserysimi (Kaltenbach), Myzus persicae (Fabricius) and the like can be parasitized by aphidius rapamicae, and the natural parasitism rate of the aphidius avenae (Fabricius) is usually 20-60%, and the highest rate can reach 89.16%.

In the research of genetic diversity of the aphidius gifuensis ashmead, living aphidius gifuensis ashmead adults are often needed, in order to ensure the precision and accuracy of the experiment, the consistency of sample sources must be ensured when extracting the DNA and RNA of the aphidius gifuensis ashmead, and meanwhile, the service life of the aphidius gifuensis ashmead adults is short, which causes great pressure on sampling. At present, substances used for supplementing nutrition for indoor artificial propagation of adult aphidius gifuensis ashmeads are mainly honey water, but the effect of prolonging the service life of adult aphidius gifuensis ashmeads is not ideal enough. In nature, adult Aphidius gifuensis Ashmaed mainly takes nectar, honeydew and the like as nutrient sources to meet the requirements of growth, development and propagation of the adult Aphidius gifuensis Ashmaed. The group provides exogenous nutrition for the aphidius gifuensis ashmead by artificially simulating energy substances in the nature, and prolongs the survival time of adult aphidius gifuensis ashmead.

Disclosure of Invention

The invention provides the nutritional supplement for prolonging the survival time of the adult aphidius gifuensis ashmeads, so that the survival time of the adult aphidius gifuensis ashmeads is prolonged.

In order to achieve the purpose, the invention provides the following technical scheme:

a nutritional supplement for improving survival time of adult aphidius gifuensis ashmeads is characterized by comprising the following components in percentage by weight: 10-12% of honey, 1-5% of freeze-dried powder of the green peach aphids, 1-2% of cane sugar, 0.5-1.5% of glucose, 0.1-0.5% of preservative and the balance of sterile water;

preferably, the nutritional supplement comprises the following components in percentage by weight: 10% of honey, 2% of peach aphid freeze-dried powder, 1.5% of cane sugar, 1% of glucose, 0.2% of preservative and the balance of sterile water;

preferably, the preparation method of the green peach aphid freeze-dried powder comprises the following steps:

(1) placing the green peach aphids in a container, placing the container in liquid nitrogen, and freezing the green peach aphids;

(2) grinding the frozen myzus persicae into powder by a grinding machine, and sieving the powder by a sieve with 150-mesh and 200-mesh to obtain myzus persicae freeze-dried powder;

preferably, the preservative is selected from one or more of potassium sorbate and methyl paraben;

preferably, the myzus persicae is 3-4-year-old wingless myzus persicae;

the invention also provides a preparation method of the nutritional supplement for prolonging survival time of adult aphidius gifuensis ashmeads, which is characterized in that honey, freeze-dried peach aphid powder, cane sugar, glucose, preservative and sterile water are weighed according to a formula proportion and then are stirred and mixed uniformly.

The invention has the beneficial effects that:

1. the nutritional supplement provided by the invention can obviously prolong the survival time of adult aphidius gifuensis ashmeads, can improve the sample processing time in scientific research experiments, and can also improve the oviposition amount of the adult aphidius gifuensis ashmeads due to the prolonging of the service life of the adult aphidius gifuensis ashmeads in the artificial scale breeding process.

2. The nutritional supplement is remarkably superior to the prior art in cost, labor consumption and operability, and has the advantages of low cost, strong operability, easy storage and the like.
