Problems solved by technology

However, due to the inability to raise beetle larvae, it is impossible to provide a large number of beetle larvae test insects for indoor drug efficacy tests or pathogenicity tests, so that it is impossible to screen and produce high-efficiency biopesticides that can be used to control long beetle larvae
At the same time, because it is difficult to solve the intermediate host problem of natural enemy insects, it is also impossible to breed natural enemy insects in large quantities
[0006] The star beetle usually produces one generation a year, and the larval period is long (more than 300 days), so it is very difficult to raise artificially. At present, there is no report on the artificial breeding of star beetle larvae
Other very few star beetle larvae are raised artificially, the composition of the artificial feed is complicated, the raw materials are not easy to obtain, and the cost is high

Embodiment 1

[0034] 1. Semi-artificial feed formula for star beetle larvae:

[0035] Casuarina sawdust 200g, soybean powder 100g, wheat bran 100g, yeast powder 10g, casein 10g, sorbic acid 4g, agar 40g, water 600ml.

[0036] 2. Semi-artificial feed production method:

[0037] Weigh 200g casuarina sawdust, 100g soybean powder, and 100g wheat bran, place them in a plastic basin, mix well, and set aside;

[0038] Weigh 10g of yeast powder, 10g of casein, and 4g of sorbic acid, place them in a beaker, mix well, and set aside;

[0039] Take 600ml of water in a stainless steel pot, add 40g of agar to it, heat and stir continuously, boil, after the agar is completely dissolved, slowly add the steps and steps The mixture is stirred while adding materials to avoid agglomeration;

[0040] Put the evenly stirred larval feed into 140ml large test tubes (length 200mm, caliber 30mm), compact the feed with a mortar stick, fill the feed to 2 / 3 of the volume of the container, and cover it...

Embodiment 2

[0051] 1. Semi-artificial feed formula for star beetle larvae:

[0052] 200g casuarina sawdust, 100g soybean powder, 100g wheat bran, 10g yeast powder, 10g casein, 4g potassium sorbate, 20g agar, 600ml water.

[0053] 2. Method for making semi-artificial feed: (same as Example 1)

[0054] 3. Breeding method of star beetle larvae:

[0055] ⑴ Collecting larvae: Catch the adult beetles in the forest, place them in insect cages, feed them with casuarina twigs, and place neem wood segments with a diameter of about 5cm for the beetles to lay eggs, and remove the larvae after laying eggs. Wooden segments are inserted into water to moisturize.

[0056] ⑵ After the adult beetle lays eggs, the eggs in the wood section are directly peeled off and artificially hatched. Artificial hatching method: gently place the eggs on filter paper moistened with sterile water, put them together in a sterile petri dish, and place them in a dark environment. They can hatch in about 10 days and put the...

Abstract

The invention provides a semi-artificial feed for anoplophora chinensis larvae and a preparation method thereof, as well as an artificial feeding method for the anoplophora chinensis larvae. The semi-artificial feed comprises the following ingredients in parts by weight: 50 to 60 parts of saw dust, 25 to 30 parts of soybean powder, 25 to 30 parts of wheat bran, 2 to 3 parts of yeast powder, 2 to 3 parts of casein, 0.5 to 1 part of food preservative, 5 to 10 parts of agar and 130 to 170 parts of water. The preparation method comprises the steps of mixing, stirring and sterilizing the raw materials; the artificial feeding method for the anoplophora chinensis larvae comprises the steps of collection and feeding of ova and larvae. The semi-artificial feed provided by the invention has the advantages of comprehensive nutritions, low cost, simple preparation method as well as simplicity and convenience for operation. By adoption of the semi-artificial feed and the feeding method provided bythe invention, a large amount of anoplophora chinensis larvae for tests can be provided for scientific researches.

Description

technical field [0001] The invention relates to a semi-artificial feed for insect larvae and an artificial feeding method, in particular to a semi-artificial feed for larvae and a feeding method thereof. technical background [0002] star beetle Anoplophora chinensis , commonly known as White Star Beetle, Silver Star Beetle, belongs to Coleoptera (Coleoptera) Cerambycidae (Cerambycidae), groove shin beetle subfamily (Lamiinae) Star Beetle ( Anoplophora Hope). The host of long beetles is very wide, and it can harm 48 species of 19 families, 29 genera. Main hosts: casuarina, poplar, willow, elm, black locust, walnut, mulberry, red toon, catalpa, tallow, sycamore, acacia, neem, sycamore, mother tree, oak, citrus and other forest fruit plants. The larvae eat the main trunk or taproot near the ground, destroying the transportation of nutrients and water in the tree, so that the tree is weakened, and the whole plant dies in severe cases. [0003] In the southeast coastal area...
