preparation example Construction

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

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

[0033] 2) after the living body of the black soldier fly larvae is washed with clear water, it is placed on a gauze cloth and laid out to dry, and the body surface of the worm is dried to obtain the living body of the black soldier fly larvae to be treated;

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

[0035] 4) spread the remaining coating material on the coated larvae ...

[0049] Example 1 Comparison of water resistance of the larvae bait of Rana wood

[0050] 1. Materials: 100 3-4 instar Tenebrio molitors, 100 3-4 instar black soldier flies 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 fences, and many pieces of white cardboard (30×30cm).

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

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

Abstract

The invention provides a coating material, coating bait for live black soldier fly larvae, a preparation method and application thereof, and belongs to the technical field of industrialized breeding bait application. The coating material of the present invention includes the following raw materials for preparation: defatted soybean powder, tussah moth powder, soybean oil, corn starch, multi-dimensional element tablets, calcium, phosphorus, magnesium, zinc and iron for veterinary rapid supplementation and xanthan gum. The nutritional components of the coating material of the invention are reasonably configured, and the coating bait for living black soldier fly larvae prepared by the coating material of the invention can meet the needs of growth, development, oil production and reproduction of Rana chinensis. The black soldier fly larvae live coated bait of the present invention solves the problem of single species and unbalanced nutrition of the live insect bait of the forest frog, greatly reduces the cost of the bait, artificially controls and balances the required nutrient content of the forest frog, and makes artificial There is no significant difference in the oil quality of the cultivated wood frog and the wild wood frog oil, and the oil production cycle is shortened by 30%, which is of great significance to the realization of the industrial scale breeding technology of the Chinese wood frog.

Description

technical field [0001] The invention relates to the technical field of industrial breeding bait application, in particular to a coating material, a black soldier fly larvae live coating bait, a preparation method and application. Background technique [0002] Forest frog, also known as Chinese forest frog, commonly known as Husky, is native to the deep mountains and jungles of the northeast. Expensive and regarded as a treasure. [0003] Since the Chinese forest frog only feeds on live insects, in the whole artificial breeding process, adults and larvae of live animals such as Tenebrio molitor, flies, and earthworms must be cultivated as bait to ensure the normal factory farming of Chinese forest frogs. The key to the success of farming. However, the cultivation of adults and larvae of live animals is restricted by many objective factors, and it is easy to die after being immersed in water, and only live animals are used as bait, the nutrition is single, and the nutritiona...
