preparation example Construction

[0031] The present invention also provides the preparation method of the black soldier fly larva live coating bait described in the above scheme, comprising the following steps:

[0032] 1) Mix and boil part of the coating material and water at 95-100°C for 5-8 minutes to obtain a coating solution with a concentration of 38-40 degrees Baume;

[0033] 2) After washing the live black soldier fly larva with clear water, place it on gauze and spread it flat to dry, and wait for the body surface of the insect body to dry to obtain the live black soldier fly larva to be treated;

[0034] 3) After cooling the coating solution to 15-25°C, immerse the live black soldier fly larvae to be treated in the cooled coating solution, take out the live black soldier fly larvae wrapped in the coating solution, let stand, and obtain the coating larva;

[0035] 4) spreading the remaining coating material on the surface of the coated larvae to obtain the live black soldier fly coating bait;

[0049] The water resistance comparison of embodiment 1 Rana larvae bait

[0050] 1. Materials: 100 3-4 instar Tenebrio molitors, 100 3-4 instar black soldier fly larvae, 100 3-4 instar fly maggots, 100 1-year-old earthworms, 10L normal temperature mineral water, timer, 2.5L beaker 4 pieces, 4 pieces of 40-mesh strainer, and several pieces of white cardboard (30×30cm).

[0051] Source of material: Jilin Sericulture Research Institute.

[0052] 2. Method: Pour 2L of mineral water into 4 beakers respectively, and pour the four kinds of experimental insects into different beakers at the same time, and start timing. When 10 (10%) of the experimental insects were observed to die in the water, the time was recorded, fished out with a strainer, and placed on a white cardboard for confirmation.

[0058] Embodiment 2 A kind of black soldier fly larva living body coating bait

[0059] 1. Components of the coating material: 300g of defatted soybean powder, 350g of tussah moth powder (seed production leftovers), 30g of soybean oil, 200g of corn starch, 1g of multi-dimensional element tablets (Anhui Jinhui Pharmaceutical Co., Ltd.), 1g of calcium, phosphorus and magnesium Zinc iron (veterinary, Daqing Boshen Biotechnology Co., Ltd.) 10g, xanthan gum (food thickener, Shenzhen Xingmu Biological Engineering Co., Ltd.) 20g.

[0060] 2. Feed: 3rd to 4th instar live black soldier fly larvae.

[0061] 3. Coating method: fully mix the coating material, divide it into 3 equal parts, add water to 2 parts and cook at 100°C, and control the concentration of the coating solution at 38-40 degrees Baume (apply Baume Metometer measurement), when cooled to 15-20°C, immerse the living 3-4 instar black soldier fly larvae after washing and drying in the coating solution, mix well, fish out wi...

Abstract

The invention provides a coating material, a hermetia illucens larva living thing coating bait, and a preparation method and application, and belongs to the techncial field of application of industrial aquaculture baits. The coating material comprises the following preparation raw materials of defatted soy flour, antheraea pernyi powder, soybean oil, corn starch, multivitamin and minerals tablets,calcium, phosphorus, magnesium, zinc and ferrum rapidly enriching tables for livestock and xanthan gum. The coating material is reasonable in matching of nutrient components, and the hermetia illucens larva living thing coating bait prepared from the coating material can meet requirements of Chinese forest frogs for growth, development, oil generation and propagation. The hermetia illucens larvaliving thing coating bait solves the problems that at current, the forest frog living insect bait is single in kinds, and unbalanced in nutrients, the cost of the baits is greatly reduced, and the content of nutrient components required by the forest frogs can be manually controlled and balanced, so that the oil quality of forest frogs which are artificial bred and the oil quality of wild forest frogs are not obvious in difference, the oil generating period is shortened by 30%, and the hermetia illucens larva living thing coating bait has important significance in realization of industrial large-scale cultivation techniques of the Chinese forest frogs.

Description

technical field [0001] The invention relates to the technical field of industrial farming bait application, in particular to a coating material, a coating bait for live black soldier fly larvae, a preparation method and application thereof. Background technique [0002] Rana, also known as Chinese Rana, commonly known as Hashi toad, is native to the deep mountains and jungles in Northeast China. Its oviduct (Rana oil) is a high-value health care product integrating medicine, food tonic and beauty. Expensive and considered a rarity. [0003] Because the Chinese forest frog only feeds on live insects, in the process of artificial breeding, the adults and larvae of living animals such as Tenebrio molitor, flies, and earthworms must be cultivated as bait, so as to ensure the normal factory breeding of the Chinese forest frog. The key to the success of farming. However, the breeding of adults and larvae of living animals is restricted by many objective factors. They are easy to...
