JPH0475558A - Green feed-containing feed for larva of coleoptera insect and production thereof - Google Patents

Abstract

PURPOSE:To obtain the subject clean green feed of excellent quality rich in nutritive components and required for bleeding a Coleoptera insect such as a beetle or a stag beetle for a pet by using young buds and leaves of a broadleaf tree as the raw material. CONSTITUTION:Young buds and leaves of a nontoxic broadleaf tree such as Japanese beech, Quercus acutissima, oak, sasanqua or sweet osmanthus are collected and cut to a prescribed size, e.g. about 2-5cm. The resultant cut material is dried to obtain a green feed. Saw dusts or tip dusts of a nontoxic broadleaf tree or a culture medium for a mushroom prepared by mixing a sugar therewith is added to the above-mentioned green feed as necessary.

Description

[Detailed Description of the Invention] (Industrial Application Field) Children show an abnormally strong interest in raising Coleoptera insects such as beetles and beetles. Feed is something that insects need throughout the day. This is an issue in the field of feed production.

(Prior art) I have not yet heard of anything manufactured or sold as feed for larvae of Coleoptera insects. A similar product is the "insect mat." This is made from the waste media used to artificially cultivate mushrooms, commonly called fenoki mushrooms, which have been prepared and sieved to sort them out. The name is insect mat, or "rug." The raw materials are cedar saw (zu and rice bran).

Beetle larvae do not eat cedar sawdust. All you have to do is crawl back and rest.

(Problem to be solved by the invention) The challenge is to develop high-quality insect feed and its production method.

It is desirable that the following conditions be met:

1. It is highly nutritious and is often eaten by insects.

2. Low cost.

3. Raw materials are abundant and there is no need to worry about obtaining them.

4゜It is safe and does not contain pathogens.

(Means and methods for solving the problem) From among the many industrial wastes around us, we select the following three and use them as raw materials.

1. Young buds and leaves of broad-leaved trees These are obtained in almost unlimited quantities every year from the process of felling or growing oak trees, which are the logs for cultivating shiitake mushrooms. In addition, pruning waste from green leaves produced every year as waste from garden management as part of the greening movement can be used as is.

2. Hardwood sawdust.

Sawmills produce an unlimited amount of it each year.

3. Waste media for shiitake mushroom cultivation.

Choose one made from hardwood. It is easy to obtain.

By using the above three materials, it is fully possible to produce feed containing green bait for raising insects at low cost. For the manufacturing method, see
Examples” will be explained.

(Example) Since beetles are soil insects, they have the following characteristics.

1. They will not settle down unless they are allowed to live in something similar to soil.

2. Unlike livestock such as cows and horses, they have small mouths, so it is necessary to adjust the feed to a size that is easy to eat in their small mouths.

First embodiment Kunugi is often cultivated as logs for shiitake mushroom cultivation.

In this case, the tree will be cut down in about 10 years. New shoots will then develop from the stump. There will be about 3 to 6 plants, and since you only need to let one grow, 2 to 5 will be thinned out within 2 to 3 years.

It is a young bud of about 2m. If only the hard woody parts are removed and the young buds and leaves are cut and dried, it becomes a highly nutritious and high-quality green food that is highly palatable to insects. It is necessary to crush it into pieces that are easy to eat.

Although it is necessary to provide beetles with something similar to soil and create a place for them to rest, soil itself is not good because not only do insects not eat it, but it is also a source of pathogens.

Sawdust from hardwood trees not only provides a haven similar to soil, but is also highly edible and nutritious for insects. Clean things don't have germs. It is best to mix this with green bait and feed it as feed and weight gainer. It is a mixture of two types of feed.

In addition to this, there are waste products from mushroom cultivation areas that are made by boiling a mixture of chips made from broad-leaved trees and rice bran. It is also good to mix these three ingredients together to make a feed that is a mixture of the three types, as it diversifies the nutrition and prevents nutrients from being concentrated.

Second Embodiment When oak trees are felled as logs for shiitake mushrooms, a large amount of young buds and young leaves are left behind as waste and sometimes turn into stones. Even after it becomes "dead branches and leaves", it can be used as a raw material for insect green bait feed. However, there are many bacteria such as sclerosis and other bacteria that are harmful to insects. During rainfall, rainwater may splash up with the soil and attach to young buds and leaves. Such materials are unsuitable for feed. It is necessary to select and use a material that is free from soil that has sprung up.

Third Embodiment There are many broad-leaved trees that have hard leaves but are suitable as feed for insects. ``Kaji, black tabby, tea, beech, etc.'''It's best to boil these and use them after the leaves become soft. It is best to avoid trees that are poisonous, such as the ``horse tree''.

(Effects of the invention) (1) Increased size of larvae The increased nutrient content of the feed has increased the size of reared larvae. Conventional Yamatori larvae were often around 20g.

There are many insects weighing around 35g that we are currently raising at our nursery.

(2) Decrease in larval mortality rate In the past, larvae were sometimes wiped out due to sclerosis, nutritional deficiencies, and other factors. Mortality rates have decreased significantly in recent years. I now have the time to think about things in a stable manner.

(3) Start of self-spawning Since rearing has become stable, I tried self-spawning from this year. I got pretty good results.

(4) Strengthening sales power Traditionally, beetles were sold mainly on May 20th and 7th.
It was held during the two-month season from ~August. As a result of my feed development, the occurrence of diseases has decreased, and even individual consumers can now raise and enjoy large, healthy insects from larva to adult. I have developed and am selling a ``Pet for Observing Insect Metamorphosis,'' a product that allows you to observe insects from larva to adult from around October to August of the following year. Results are starting to appear one after another.

Claims (1)
