Problems solved by technology

But at present, researches on the artificial breeding of the parasitoid Lepidopteran pests in tea gardens-the wasps are still relatively rare; if the artificial breeding of the wasps is carried out, the same artificial breeding method as other parasitoids should be adopted, because each bee species has different habits. There is a certain difference. The artificial breeding method of other bee species is used to breed gnats. Although the artificial breeding of gnats can also be carried out, the bee production rate of the artificial breeding pair is relatively low, which leads to the low efficiency of artificial breeding gnats. ,higher cost

Embodiment 1

[0037] A kind of artificial breeding method of tea garden gnat wasp, flow process is as follows figure 1 shown, including the following steps:

[0038] A1, collection of bee species: collect tea garden tea geometrid, gray tea geometrid, tea caterpillar and other lepidoptera pest pupae, carry out indoor rearing, after the gnat bee emerges, select the gnat bee with strong body and strong activity ability among them as the first generation of bees;

[0039] A2. Propagation of bee species: use tussah silkworm chrysalis with clear and transparent cranial top plate, compact and non-shrinking pupal abdomen, and tough and shiny pupa skin as an alternative host. After cleaning and disinfecting with 75% alcohol and drying it, place it in the numerous beehive, insert the first-generation kind of bees obtained in step A1 into the numerous beehive according to the ratio of bee pupa to 200:1, and put 10% Cotton balls with honey water to supplement nutrition for the adult gnat wasps;

[0...

Embodiment 2- Embodiment 5

[0051] Compared with Example 1, Embodiment 2-Example 5 differs only in that the bee-pupa ratio in Table 1 is used for the artificial propagation of gnats.

[0052] Table 1:

[0053] Example Example 1 Example 2 Example 3 Example 4 Example 5 Ratio of bee pupae in bee species expansion in A2 200 / 1 10 / 1 50 / 1 100 / 1 150 / 1 Ratio of receiving bees and pupae in batches in A4 200 / 1 10 / 1 50 / 1 100 / 1 150 / 1

[0054] The test result that final embodiment 1-embodiment 5 obtains is as figure 2 As shown, when the bee-to-pupa ratio is 200:1, the number of gnats is the largest, but within the range of 100:1-200:1, the difference in the number of bees is not very big.

Embodiment 6- Embodiment 10

[0056] Compared with Example 1, Example 6-Example 10 is only different in that the cultivation temperature in Table 2 is used for the artificial propagation of gnats.

[0057] Table 2:

[0058]

[0059] The test result that final embodiment 1, embodiment 6-embodiment 10 obtains is as image 3 As shown, when the second-generation culture temperature and the A5 step culture temperature are in the range of 24-26°C, the parasitism rate of the wasp is higher, and the parasitism rate of the wasp is the highest at 24°C.

Abstract

The invention belongs to the technical field of animal artificial breeding, and discloses an artificial breeding method for gnat bees in tea gardens, which includes collecting bee species: collecting the pupae of Lepidoptera pests in tea gardens, which are used as the first generation seed bees after the gnats are hatched; Species expansion: Use tussah silkworm pupae as a substitute host, insert the first generation of bees into the breeding beehive according to the bee pupa ratio of 10:1-200:1; Ventilated cultivation at 24°C-26°C and humidity of 40%-60%; Batch inoculation of bees: use the obtained second-generation seed bees to inoculate tussah silkworm pupae in batches; cultivation and development: at a temperature of 24°C-26°C and a humidity of 40 %-60% culture; cold storage: after the parasitic tussah chrysalis were cultivated and developed for 10 days, the cultured and developed gnats were subjected to diapause treatment, and then refrigerated; Warm the bees and release the bees at 25°C. The invention can improve the bee yield rate of the artificial breeding of the gnats, improve the efficiency of the artificial breeding of the gnats, and reduce the cost of artificial breeding.

Description

technical field [0001] The invention relates to the technical field of animal artificial breeding, in particular to an artificial breeding method for tea garden gnats. Background technique [0002] my country is the largest tea-producing country in the world, and the development of the tea industry is of great significance to the development of my country's rural areas and the increase of farmers' income. At present, the control of tea pests and diseases mainly relies on chemical pesticides. However, the excessive use of chemical pesticides has brought about ecological environment damage, agricultural non-point source pollution, and tea quality and safety, which has affected the sustainable development of the tea industry. [0003] With the development of social economy and the improvement of people's living standards, the status and role of biological control in the integrated management of diseases and insect pests has become more and more important, and it has become a re...
