Description

Technical Field

[0001] The invention relates to the technical field of insect breeding, and in particular to a device and method for breeding amber silkworms. Background Art

[0002] The scientific name of the amber silkworm is the hook-winged giant silk moth, which is an important economic insect belonging to the genus Antheraea of ​​the family Saturniidae of the order Lepidoptera. The amber silkworm is well-known for its natural golden silk, which is shiny, strong and durable. It is distributed in Yunnan, Guangdong, Guangxi Zhuang Autonomous Region and other places in China. The amber silkworm is polymorphic and is currently mainly domesticated indoors and raised outdoors. It is extremely urgent to carry out indoor and outdoor breeding research on amber silkworms, as well as to carry out large-scale breeding of amber silkworms. The breeding of amber silkworms is expected to be an effective way to solve the current problem of silkworms as a single silk-spinning insect.

[0003] In current technology, indoor breeding mainly adopts breeding boxes and net cages. The body shape of amber silkworms changes greatly from 1st instar larvae to 5th instar larvae, and they have different feeding habits. However, the interior of traditional breeding boxes is smooth, which is not conducive to the climbing of amber silkworms and causes them to starve to death. Solving the problem of their climbing on the edge of the breeding device is also one of the problems. Therefore, it is a direction to solve the current situation to develop a method that is simple to operate, easy to handle, has high breeding efficiency, can breed amber silkworms in large quantities, and takes into account the growth needs of amber silkworms at different ages. The breeding method has a stable environment. Summary of the invention

[0014] By adopting the above technical solution, the temperature and humidity in the breeding box can be lowered when necessary, and when not needed, the cover can be used to prevent excessive dissipation of the temperature and humidity in the breeding box.

[0015] The present invention is further configured as follows: the upper end of each support plate outer wall is provided with a plurality of slots distributed at equal intervals downward along its length direction, and each slot is detachably connected with a plurality of water-containing pipes that are cooperating and snap-fitted therewith and have open upper ends.

[0016] By adopting the above technical scheme, not only can the humidity in the breeding box be adjusted by the water in the water pipe, but also the cinnamon can be kept in a vertical upward state at all times when placed, so as to facilitate the feeding of the amber silkworm.

[0017] The present invention is further configured as follows: the temperature in the breeding box is controlled at 26-28° C., the humidity is controlled at 65%-75%, and the breeding area is ventilated and exhausted for 30 minutes every day.

[0018] The present invention also provides an amber silkworm breeding method, which is characterized in that the amber silkworm breeding method comprises the following steps:

[0019] Step 1: Planting of the osmanthus plant. The osmanthus plant is planted outdoors, and the plant height is trimmed to 3 meters. The tender branches growing around it are retained. The branches are cut once a year, and the main branches are retained when cutting.

[0021] Step 3: The eggs begin to hatch 9-10 days after they are laid. After adjusting the temperature and humidity in the breeding box, the 1-3 instar larvae of amber silkworms are raised at a high density using the low-instar larvae co-rearing method, and the low-instar larvae are raised in the breeding box;

[0022] Step 4: raising high-age larvae, raising 4-5 instar larvae of amber silkworms by high-age larvae separation method, and raising high-age larvae in the breeding tank according to any one of claims 1 to 6;

[0023] Step 5: Seed production. After the amber silkworms form cocoons, they are stored at a constant temperature of 10-15℃ for seed preservation and 24-28℃ for seed production. After the adults emerge, they are subjected to free mating for seed production and succession breeding.

[0024] Further: the method of co-rearing low-age larvae is: adopt high-density breeding, insert the Osmanthus dahurica into a water pipe filled with clean water, put it in the breeding area on one side of the breeding box, and let the leaves contact the egg placement component, the larvae transfer to the Osmanthus dahurica along the leaves to feed, and put 200-300 larvae in each breeding box; after breeding for 5 days, put the Osmanthus dahurica on the other side of the breeding box, let the newly added Osmanthus dahurica and the old Osmanthus dahurica branches and leaves contact each other; after five days, replace the Osmanthus dahurica in the breeding area on one side of the breeding box, and when replacing, take out the old branches and put in the newly pruned Osmanthus dahurica.

[0025] Further: The method for separating and breeding older larvae is as follows: reduce the density of breeding, use breeding tanks, and place the breeding tanks on plastic film; trim the branches of the Osmanthus jasminoides and place them with the base of the branches facing downward in the breeding tanks; transfer 50-80 4th-5th instar larvae of amber silkworms to each breeding tank, transfer the larvae to the leaves, and allow them to freely climb onto the Osmanthus jasminoides to feed; replace the leaves with fresh Osmanthus jasminoides every 5 days, and transfer the amber silkworm larvae to new leaves.

[0026] In summary, the present invention has the following beneficial effects:

[0027] First, the present invention raises amber silkworms indoors through a certain device, which can effectively improve the survival rate of larvae when amber silkworms are raised in large quantities, reduce the loss of silkworm bodies, and improve the breeding and expansion efficiency;

[0028] Secondly, the two feeding areas of the feeding box of the present invention are separated by a partition so that the host plants can be rotated into the feeding box, so that the larvae can climb to fresh branches spontaneously without manual selection and transfer;

[0029] Thirdly, the breeding tank of the present invention can not only completely place the host plant in the tank body for the convenience of amber silkworm breeding, but also the water film sprayed on the inner wall of the tank cover and not flowing down plays the role of moisturizing the inside of the breeding tank.

[0043] A method for raising an amber silkworm, comprising the following steps:

[0044] Step 1: Planting of the osmanthus plant. The osmanthus plant is planted outdoors, and the plant height is trimmed to 3 meters. The tender branches growing around it are retained. The branches are cut once a year, and the main branches are retained when cutting.

[0045] Step 2: Install the low-age larvae rearing device, insert the support plate 32 into the fixing groove 31, then separate the connecting pipe 19 of the egg placement assembly 18 from the connecting frame 21, then insert the connecting pipe into the corresponding fixing hole 17 on one side of the feeding box 1, and then connect it to the lower end of the connecting pipe 19 through the internal thread 23 and the external thread 24. 7 days after the eggs are laid, insert the osmanthus fragrans into the water pipe 34 filled with clean water and then put it into the notch 33 in the corresponding feeding area 13, then place the eggs on the egg placing plate 22 through the egg placing bucket 2 and the connecting pipe 19, then insert the partition 12 into the chute 11 to leave the feeding area 13 on the other side of the feeding box 1, and place it in the reserved empty feeding area 13 when replacing the leaves after 5-7 days;

[0046] Step 3: The eggs begin to hatch 9-10 days after they are laid. The temperature of the feeding box 1 is controlled to 26-28°C, and the humidity is controlled to 65%-75%. Then, the 1-3 instar larvae of amber silkworms are raised at a high density using the low-instar larvae co-breeding method. Since the 1-3 instar larvae are small and have a low food intake, high-density feeding is adopted in the feeding box 1 to ensure that the larvae can find food more quickly and feed more cleanly, thereby improving feeding efficiency and reducing energy consumption. 200-300 larvae are placed in the corresponding feeding area 13, and the osmanthus ternatus is inserted into a water pipe 34 filled with clean water and placed in the feeding area 13 on one side of the feeding box 1. The leaves are allowed to contact the egg-laying plate 22 of the egg placement component 18, so that the larvae can be transferred to the osmanthus ternatus along the leaves to feed. The larvae of amber silkworms that fall on the bottom of the feeding area 13 can climb onto the leaves of the osmanthus ternatus through the climbing net 41 to continue feeding.

[0047] After 5 days of feeding, new osmanthus is placed in the other side of the feeding box 1, and then the partition 12 is pulled out from the slide 11, so that the newly added osmanthus is in contact with the old osmanthus branches and leaves, so as to facilitate the climbing and transfer of the amber silkworm larvae. After five days, the osmanthus in the feeding area 13 on one side of the feeding box 1 is replaced. When replacing, the old branches are taken out and the newly pruned osmanthus is placed in the water pipe 34 to feed the young larvae. When the amber silkworms are raised to the 4th instar, the feeding tank 35 is replaced to feed the old larvae. In this process, the air permeable net 16 on the through groove 15 can ensure the normal flow of air in the feeding box 1, and during the whole feeding process, the temperature and humidity sensor 3 can try to monitor the temperature and humidity changes in the feeding box 1. If it exceeds the preset value, the exhaust component 26 in the through hole 25 is operated, the cover 29 is opened, the exhaust fan 28 is operated and the temperature and humidity in the feeding box 1 are reduced through the exhaust pipe 27, and ventilation is carried out for 30 minutes every day.

[0048] Step 4: Raising high-age larvae: Raise 4-5 instar larvae of amber silkworms by high-age larvae separation method, transfer low-age larvae with higher density from the breeding box 1 to the breeding tank 35, so that high-age larvae have more space, which is convenient for low-density breeding. First, remove the cylinder cover 37 on the cylinder body 36, then place the cylinder body 36 on the plastic film, and then lay the climbing net 41 on the inner wall of the cylinder body 36, then trim the cinnamon sticks to 50-100CM, and put them into the breeding tank 35 with their base downward, so that the cinnamon sticks fill the entire cylinder body 36, and then trim the cinnamon sticks that exceed the open end of the cylinder body 36 to make them flush with the open end of the cylinder body 36;

[0049] Then, 50 to 80 4th to 5th instar larvae of amber silkworms are transferred into the cylinder body 36 and placed on leaves, allowing them to climb onto the osmanthus fragrans to feed. Then, water is sprayed onto the inner wall of the cylinder cover 37 until water droplets do not flow down in strands and a water film is formed, and then the cylinder cover 37 is covered on the cylinder body 36. Next, fresh osmanthus fragrans is replaced every 5 days, and the amber silkworm larvae are transferred to new leaves. After the amber silkworms cocoon, the amber silkworm cocoons are collected. The air holes 38 can ensure the normal circulation of air inside the breeding cylinder 35, and the feces separation net 39 can separate the amber silkworm larvae from the feces they produce.

[0050] Step 5: seed production. After the amber silkworms form cocoons, they are kept at a constant temperature of 10-15°C for seed preservation and at a constant temperature of 24-28°C for seed production. After the adults emerge, they are subjected to free mating for seed production and succession rearing. Low temperature is used for seed preservation. After the amber silkworm pupae are kept for 4-6 months, the temperature can be increased so that they can emerge and reproduce smoothly, while high temperature is used for seed production, which is suitable for their mating temperature. After use, open the box door 14 and conduct comprehensive sterilization and disinfection on the feeding box 1 and the feeding tank 35.

[0051] Setting up the experimental group

[0052] Amber silkworms for test: The amber silkworms for test were raised for many generations in the resource silkworm seed factory in the Institute of Sericulture and Beekeeping of Yunnan Academy of Agricultural Sciences. The seed cocoons from the same batch were selected before the test. After the amber silkworms emerged as adults, the males and females were paired for mating. After mating, the female adults were transferred to the egg-laying box and allowed to lay eggs for 5 days. The eggs were soaked in 5% formaldehyde solution for 30 seconds and then rinsed with clean water for 4-5 times. The disinfected amber silkworm eggs were placed in a climate box and allowed to develop for 7 days before being taken out for use.

[0053] The experiment was carried out under two conditions. Condition 1 was to insert the twigs of Cinnamomum dahurica into a plastic water bottle, put it into the insect cage, and raise it indoors, and the twigs of Cinnamomum dahurica were replaced regularly.

[0054] Condition 2 is set as follows: when the amber silkworm is young, the branches of the osmanthus cinnamomea are inserted into a water bottle and are raised in the low-age larvae breeding box device of the present invention, and the old amber silkworm is raised in the old-age breeding tank device of the present invention. The two conditions are set in the same room for breeding, and the osmanthus cinnamomea branches are replaced regularly. The indoor temperature, humidity and other conditions are the same under the two conditions.

[0055] Experimental Group 1: Statistics of host replacement time:

[0056] The host branches were placed in the chamber, and 10 groups were raised under each condition. The replacement time of the cassia branches was based on the obvious wilting of the leaves, water loss, and reduced feeding of the larvae. Based on the above standards, the earliest replacement time and the latest replacement time interval were calculated.

[0057] The experiment was carried out under two conditions. Condition 1 was set as follows: Cinnamomum dahliae branches were inserted into a plastic water bottle, placed in an insect cage, and raised indoors, with Cinnamomum dahliae branches replaced regularly; Condition 2 was set as follows: when the amber silkworm was young, Cinnamomum dahliae branches were inserted into a water bottle and raised in a low-age larvae rearing box device of the present invention, and the old amber silkworm was raised in an old-age rearing tank device of the present invention. The two conditions were set to be raised in the same room, with Cinnamomum dahliae branches replaced regularly. The indoor temperature, humidity and other conditions were the same under the two conditions.

[0058] Experimental results: Host replacement time of larvae in all stages under different rearing methods

[0059] Age Cage breeding (days) This invention (days) 1 year old 1-3 4-5 2 years old 1-3 4-5 3 years old 1-3 4-6 4 years old 2-3 4-5 5 years old 2-3 5-6

[0060] Table 1

[0061] The above test results show that after the 1-5 instar larvae of amber silkworms are raised in net cages and the device and method of the present invention, the host replacement time of the net cage breeding is 1-3 days, which is significantly lower than the replacement time of 4-6 days of the breeding method of the present invention (Table 1). Especially when the amber silkworms are young, the host plants need to be replaced more timely. After the host wilts and dries up, the amber silkworm larvae will no longer feed and crawl around, which seriously affects the growth and development of the amber silkworms. The breeding device of the present invention has a longer preservation ability.

[0062] In actual breeding, if the host is changed frequently, a lot of time will be wasted, more manpower will be consumed, the breeding efficiency will be lowered, and the output will be less. If the amber silkworm feeds on poorer leaves, its development will be indirectly affected. When raising young larvae in the breeding box of the present invention, it is only necessary to place fresh plants in the empty compartments. The amber silkworm will automatically find food, and after automatically transferring to the new plant, the old branches can be easily taken out, which greatly reduces the complex operation of manual sorting of individual amber silkworms.

[0063] Experimental group 2: Effects of different feeding methods on the weight of amber silkworm pupae:

[0064] The amber silkworm larvae were raised normally to make cocoons. The cocoons were observed and recorded 7 days after the cocooning was completed. The male and female pupae were distinguished by the morphology of the genitals and antennae and the pupae were weighed.

[0065] Experimental results: Weight of amber silkworm pupae under different feeding methods

[0066]

[0067] Table 2

[0068] The above test results show that there is a difference in the weight of amber silkworm pupae raised in net cages and in the two methods of raising them in suitable devices in stages according to the present invention. The weight of amber silkworm pupae is related to the growth and development of the larvae, the nutrient content of the host and the amount of food they eat. In the same environment, amber silkworms raised in net cages are more susceptible to fluctuations in external conditions. The raising method of the present invention is adapted to the growth habits of amber silkworms, a relatively stable microenvironment can be maintained in the raising box, the host is not easy to wilt, and the amber silkworms have convenient feeding conditions in the device.

[0069] If the amber silkworm larvae do not have good nutritional supplements when eating during the feeding process, and the feeding device is not adjusted in time at different growth stages of the amber silkworm, the amber silkworm will be in a relatively poor state, resulting in a relatively low weight of the pupa. The weight of the pupa is related to the amount of eggs laid by the adults and the health of the offspring to a certain extent. The method of the present invention can increase the reproduction of the offspring to a certain extent, and has a better feeding effect.

[0070] Experimental group 3: Effects of different feeding methods on the survival rate of amber silkworms at different ages:

[0071] Statistical method for larval survival rate: The total number of amber silkworm larvae of different ages is counted when the silkworms are started, and they are allowed to feed and grow on the host plants. The age and survival of the larvae are counted every two days, and the number of remaining larvae is counted when the larvae reach the next age.

[0072] Larval survival rate (%) = number of silkworms of the next instar / number of silkworms of this instar.

[0073] Experimental results: The survival rate of amber silkworms at different ages raised in large quantities by different feeding methods

[0074] Age Cage breeding (%) The present invention (%) 1 year old 60.33 75.67 2 years old 61.00 75.00 3 years old 65.33 76.67 4 years old 77.00 86.33 5 years old 84.00 94.00

[0075] Table 3

[0076] Test results: The above test results show that after raising amber silkworms in two ways, namely, cage breeding and the present invention, the survival rate of 1-5 instar larvae of amber silkworms in the cage is lower than that in the present invention, wherein the survival rates of 1-5 instar larvae are respectively lower than 9.33%-15.33%. The survival rate of the present invention, especially when the amber silkworms are young, is much higher than that of the cage breeding (Table 3). The stress resistance of young larvae of amber silkworms is lower than that of old larvae. When they are raised in a cage, they are easily affected by the breeding environment and their survival rate is reduced. The present invention provides a larger breeding space and has a more convenient operation method. The Osmanthus fragrans leaves placed therein can be directly leaned against the device without deformation, which is more conducive to the activity of amber silkworms, more convenient to operate, and faster to replace Osmanthus fragrans branches.

[0077] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make creative modifications to this embodiment as needed, but as long as it is within the scope of the claims of the present invention, it will be protected by the patent law.
