In order to achieve the technical problem described above, the present invention has been studied several times to find out the growth characteristics of the outer jeopardy, and it was confirmed that the growth state according to the specific breeding temperature and photoperiod environment, and the specific feeding.

Hereinafter, a detailed look at the artificial breeding method of the outer jeopardy of the present invention.

1) Breeding temperature condition and photoperiod condition

Odyssey showed a shorter development period and higher survival rate in 25 ~ 35 ℃ breeding temperature and 15 ~ 18L photoperiod environment at all growth stages.

In other words, even insects belonging to the same family will have a significant effect on growth and survival rate depending on the breeding temperature and photoperiod condition applied during artificial breeding.

Therefore, in the present invention as a result of breeding the outer skin by setting various breeding temperature of 20 ~ 35 ℃ under 16L: 8D photoperiod from the egg hatching to pupa stage, eggs are breeding temperature of 25 ~ 35 ℃ and 16L: 8D Incubation under conditions showed a short hatching period, especially at 25 ° C.

The larvae of the outer edicles have a short development period at 25 ~ 35 ° C., and their development condition is also good. Among them, the growth period is shortest at 35 ° C., but the survival rate is almost 100% at 25 ° C. As a result, it can be seen that the most suitable breeding temperature is 25 ℃ based on the integrated preparation of growth period and survival rate.

The pupa of the dormitory is also short in the pupal state at 25 ~ 35 ℃, while the pupa period is the shortest at 35 ℃, but in the allegory rate indicating survival rate, almost 100% survive at 25 ℃ As a result, it can be seen that the most suitable breeding temperature is 25 ℃ based on the combined pupal period and survival rate.

2) feeding condition

All insects are significantly affected by growth and survival rate depending on the type and amount of food fed at the time of artificial mass breeding.

Therefore, in the present invention, the survival rate for each type of food is confirmed under the breeding temperature condition having the highest survival rate, and the survival rate is increased when the feed is mixed with radish compared to the case of feeding the wheat bran, which is normally fed, At this time, the mixing ratio of the bran and radish was confirmed that the survival rate is high when made of 1: 0.1 to 0.5 by weight.

In other words, in the case of radish contains a lot of moisture, if supplied by more than 0.5 weight ratio based on the weight of the bran, rather than the possibility of survival of harmful microorganisms due to radish, rather than reduce the survival rate of the jeopsae, 0.1 weight ratio If supplied below, the content is so small that the survival rate is still low. Feeding mixed foods mixed with bran and radish 1: 0.1 ~ 0.5 weight ratio to raise the outer skin is the best survival rate in mass production. It can be seen that.

In addition, the mixed feed may be configured to further add a wood chip, wherein the wood chip is composed of finely divided into a chip form that is easy to burn after separating the roots and branches, other wood waste, which is not commonly used as construction wood, By putting the same content as the bran, it will exhibit an effect of slightly increasing the survival rate of the outer erosion.

As a result of confirming the total development period from the egg hatching to the pupa stage, it shows that the development period is 30-50 days, which is much faster than other mealworms and insects, which usually have a development period of more than 3 to 6 months. Keeping in mind that insects are widely used as feed materials, it is possible to supply materials smoothly as demand increases, and it is also easy to use in farms, and it is expected to increase labor efficiency. do.

Hereinafter, the present invention will be described in more detail with reference to Examples.
