Abstract

The invention discloses a insect breeding method, especially a low cost method for raising first-instar wild silkworm using artificial feedstuff. Sterilizing silkworm egg surface, transferring newly hatched wild silkworm to closed container placed with artificial feedstuff under dark condition, environment temperature 25+/-1 degree, relative humidity 70-75%. Dimension of container is 60-70cm<2>*1.6-1.8cm, feeding density is 0.9-1.2 /cm<2>. After 6-8 days second-instar wild silkworm is bred. The present invention effectively increase the feedstuff intake of wild silkworm and promote second-instar newly-molted silkworm rate by limiting the breeding number, controlling the container dimension and shrinking the movement space. The present invention also reduce the cost and be suitable for batch production due to that the artificial feedstuff has property of saving labor, cleaning and not limiting by environment condition and that the feedstuff has not include the agar.

Description

A kind of raise 1 age Bombyx mandarina method

Technical field

The present invention relates to the raising method of a kind of insect, especially a kind of with the low-cost artificial feed raise 1 age Bombyx mandarina method.

Background technology

Bombyx mandarina and silkworm belong to Lepidoptera bombyx mori section together, and they have common ancestors---ancient Bombyx mandarina.Bombyx mandarina is eliminated through the selection of very long wild environment and is continued, then directed selection cultivation under indoor artificial condition of silkworm.Therefore, Bombyx mandarina has the quality that many silkworms do not have, as resistance, pesticide resistance, to the strong grip of adaptability, abdominal foot of alternating temperature, the activity of taking action, the ability of migrating, mimicry etc., always be much accounted of and utilize as silkworm physiology, ecological comparative studies object and the genetic resources of genetic breeding.But Bombyx mandarina is survived under natural environmental condition, can carry various pathogene and parasite in the body, brings interference to research, and hope can be at indoor feeding.Though there are the human mulberry leaf to raise Bombyx mandarina, because mulberry leaf are subjected to seasonal restriction, can not annually raise, therefore, it is very necessary that artificial feed are raised Bombyx mandarina.

Before the present invention makes, being entitled as in the research paper of " relative moisture is to the influence of artificial feeding wild silkworm in feed water content and the air " [Zhejiang agricultural journal 2 (4): 181-185.1990] and " Primary Study of wild silkworm mixed feed and artificial feeding " [agriculture journal 7 (1): the 51-54.1995 in Zhejiang] and disclosing under uniform temperature and relative moisture raising condition, is 22 * 15 * 5cm at volume ³Container in raise the method for the artificial feeding of 100～150 Bombyx mandarina newly hatched larvaes because employed feed for containing agar class artificial feed, has increased the cost of raising wild silkworm in batches.

At present, general business-like silkworm is mulberry leaf powder, defatted soy flour, the green branch of mulberry powder, starch, citric acid, vitamins, preservative, mineral salt etc. with the artificial feed main component, use and do not contain the agar artificial feed, the feeding cost of Bombyx mandarina will be reduced, help producing in batches, to satisfy the needs of scientific research and other application.Yet, in the process of Bombyx mandarina artificial feeding, the difficult point of raising be 1 age silkworm, therefore, how to solve 1 age Bombyx mandarina the artificial feeding problem be to improve the Bombyx mandarina ability of raising in batches, reduce the key point of raising cost.

Summary of the invention

The objective of the invention is to overcome the deficiency that prior art exists, provide a kind of easy, safe, 2 age Bombyx mandarina play silkworm rate height, and artificial feed with low cost raise 1 age Bombyx mandarina method.

Technical scheme of the present invention is: after silkworm egg is carried out ovum face sterilization treatment, raise that environment is that 25 ± 1 ℃ of temperature, relative moisture are 70～75%, under the dark condition, the Bombyx mandarina newly-hatched silkworm of hatching is moved in the closed container that is placed with artificial feed, and the volume of container is 60～70cm ²* 1.6～1.8cm, raising density is 0.9～1.2/cm ², bred through 6～8 days 2 age Bombyx mandarina play silkworm.

Before supporting Bombyx mandarina, silkworm room, rearing instrument clean, sterilize.Artificial feed are 5 * 2 * 0.2～0.3cm ³Sheet, the phase of raising for 1 age is to once totally 3～4 of baits.

Compared with prior art, the invention has the advantages that: at Bombyx mandarina habit open country, be not good at living in groups easily diffusion, the growth characteristics that phototaxis is strong, raise a number, control the volume of raising container by qualification, suitably dwindle its activity space, the characteristics that the distinctive life habit of Bombyx mandarina and artificial feed are raised combine, and have effectively increased the probability of its feed of ingesting, improved for 2 ages and played the silkworm rate, make 1 age Bombyx mandarina raise with the low-cost artificial feed and become possibility; Simultaneously,, especially used the artificial feed that do not contain agar, will reduce cost, be beneficial to batch process because artificial feed have laborsaving, health, not limited by the mulberry leaf environmental condition.

Description of drawings

Fig. 1 be adopt the different container of volume raise 1 age Bombyx mandarina to playing the contrast histogram of silkworm rate influence 2 ages, wherein, volume receptacle is respectively: A=65cm ²* 1.8cm, B=110cm ²* 2cm, C=160cm ²* 6cm;

Fig. 2 be adopt different raise density raise 1 age Bombyx mandarina to playing the contrast histogram of silkworm rate influence 2 ages, wherein, raise density and be respectively: a=0.6 head/cm ², b=0.9 head/cm ², c=1.2 head/cm ², d=1.5 head/cm ², e=1.8 head/cm ², f=2.1 head/cm ²

Embodiment

Below in conjunction with drawings and Examples the present invention is further described:

Embodiment:

Artificial feed raise 1 age Bombyx mandarina method, its step is as follows:

1, before the raising Bombyx mandarina, earlier silkworm room, rearing instrument are cleaned, sterilizes; And silkworm egg carried out ovum face sterilization treatment;

2, press artificial feed operation instruction formula feed, and be processed into 5 * 2 * 0.2cm ³Sheet;

3, the Bombyx mandarina newly-hatched silkworm with hatching moves in the closed container that is placed with 3～4 artificial feed, and the volume of container is 65cm ³* 1.8cm, raising density is 0.9/cm ²

4, be 25 ± 1 ℃ in temperature, relative moisture is 70～75%, and light is dark raising in the environment, and give bait once full age, through 6～8d develop into 2 age Bombyx mandarina play silkworm.

Referring to accompanying drawing 1, be respectively: A=65cm at vessel volume ²* 1.8cm, B=110cm ²* 2cm, C=160cm ²Raise under the condition of 80 newly-hatched silkworms in each container of * 6cm, can be seen by Fig. 1, raising vessel volume is 65cm ²It is the highest that play the silkworm rate 2 ages during * 1.8cm.

Referring to accompanying drawing 2, at the identical container (65cm that raises ²* 1.8cm) under the condition, raise density and be respectively: a=0.6 head/cm ², b=0.9 head/cm ², c=1.2 head/cm ², d=1.5 head/cm ², e=1.8 head/cm ², f=2.1 head/cm ², as seen from Figure 2, raise 0.6/cm of density ², 0.9/cm ²With 1.2/cm ²2 ages play silkworm rate height.Raise the container service efficiency for raising, raise density with 0.9～1.2cm ²Be advisable.

By embodiment of the invention technical scheme artificial feed raise 1 age Bombyx mandarina, play the silkworm rate 2 ages and reached 50～60%; Continue to raise with playing silkworm these 2 ages, the rate of cocooing can reach 45～50%, changes the moth rate and can reach 40～45%.Artificial feed provided by the present invention raise 1 age Bombyx mandarina method, have easy, safe, characteristics effectively and cheaply, the small lot that helps Bombyx mandarina is manually produced, to satisfy the demand of scientific research and other application facet.
