Description

Technical Field

[0001] The invention relates to the technical field of insect breeding and growth and development observation, and in particular to an amber silkworm growth and development observation device and a use method. Background Art

[0002] The amber silkworm Antheraea assama belongs to the family Bombyx mori of the order Lepidoptera and is one of the less studied wild silkworms in China. The amber silkworm is mainly distributed in Yunnan, Guangxi and Guangdong. It is popular because of its special silk color and soft texture. It can be used to make precious silk fabrics such as silk pillows and silk quilts. If the amber silkworm resources can be cultivated on a large scale, it will become a very valuable economic insect. However, at present, there is no systematic domestication and breeding of amber silkworms in China, and the understanding of their biological characteristics is not comprehensive. In particular, the growth and development of amber silkworms on different hosts is still unclear.

[0003] The current amber silkworm breeding technology and equipment are imperfect. The existing breeding equipment is not convenient for observing the growth and development of amber silkworms during the amber silkworm breeding process, and the growth and development status cannot be accurately recorded. Secondly, the main problem is that the amber silkworms cannot eat fresh leaves in time during artificial pruning breeding, which affects their growth and development. Further, it cannot accurately reflect the most real growth and development time of the amber silkworms, and there are more experimental errors. And the wilted leaves will also affect the growth and health of the amber silkworms. Therefore, it is impossible to accurately grasp the growth and development rules of the amber silkworms, which will cause difficulties for the subsequent research on the expansion and promotion of amber silkworm production technology. Furthermore, when the amber silkworms are raised on living plants, they have the ability to crawl, and it is difficult to mark each larvae. In the process of the growth of lake silkworms, it is difficult to track and observe their growth from beginning to end. Especially in the early stage of breeding, mastering their growth cycle is the basic work for subsequent research. Therefore, finding a single-head breeding method and simulating the outdoor growth environment of amber silkworms is crucial to accurately grasp their development cycle. This patent relates to an amber silkworm growth and development observation device and a method of use, which can effectively solve the problem that the growth and development of amber silkworms cannot be observed during the current breeding process, and can effectively improve the survival rate of amber silkworm larvae and improve the accuracy of their growth and development observations.

[0063] Example 3

[0064] Effects of different rearing methods on the developmental period of amber silkworm

[0065] Amber silkworms for testing: The amber silkworms for testing were raised for many generations in the resource silkworm seed factory of the Institute of Sericulture and Bees of Yunnan Academy of Agricultural Sciences. Seed cocoons of similar size were selected before the test. After the amber silkworms emerge in the seed production room, the male and female are paired for mating. After mating, the female adults are transferred to the egg-laying box. After the eggs are laid, the eggs are disinfected and hatched for the experiment. Greenhouse conditions: The condition temperature is 26-28℃, the light and dark cycle adopts the natural light time in summer, and the breeding humidity is 60%-70%.

[0066] Statistics of amber developmental period: After the amber silkworms are hatched, 50 one-year-old amber silkworm larvae hatched on the same day are selected, and the 50 larvae are connected to camphor trees under two conditions. Condition one is set as inserting camphor tree branches into a water bottle, putting them in a storage box for feeding, feeding them in a large greenhouse, and regularly replacing camphor tree branches; Condition two is set as feeding in the same greenhouse, and the camphor trees are planted in large flower pots and then raised by the present invention. In the same environment under two conditions. Observe the growth and development of amber silkworm larvae every day, and when more than 95% of the larvae enter the next instar, record the developmental period of the current instar. For the convenience of recording, each amber silkworm larvae is raised separately during the experiment, and the developmental period of the next instar is recorded.

[0067] Test results: The above test results show that the developmental duration of amber silkworm larvae at different ages after being raised under two conditions is longer than that of the observation device of the present invention (Table 1), and the span of the larval duration is larger. When the young larvae are raised in a storage box, it takes a long time to complete an age, while when they are raised in the device of the present invention, the age of the larvae tends to be shortened. At the same time, the developmental time of each age of the young larvae is relatively close. The young larvae of the present invention almost do not need to replace the leaves for the larvae to feed, while when the young larvae are raised in the storage box, the leaves need to be replaced in time because of the wilting of the leaves, and the work is cumbersome and complicated. At the advanced age, the individual amber silkworm larvae are larger and the food intake is large, and the duration of the two feeding methods is close. The above results are due to the fact that when the amber silkworm feeds on the host plant, the leaves of the plants raised in the storage box are easy to wilt and difficult to keep moist, especially when the feeding speed of the young larvae is slowed down, which indirectly affects its development time. The method of the present invention is adopted to directly raise the silkworms on the host plant, so that the silkworms will not wilt before the host has finished feeding. The silkworms can feed on fresh leaves and complete their development better.

[0070] Example 4

[0071] Effects of different rearing methods on male and female pupae of amber silkworm larvae

[0072] The operation methods of the tested amber silkworms, the disinfection method of silkworm eggs, the setting of conditions in the greenhouse, etc. are the same as those in Example 3. Condition 1 is set as inserting camphor tree branches into a water bottle, placing them in a storage box for feeding, feeding them in a large greenhouse, and regularly replacing camphor tree branches; Condition 2 is set as feeding in the same greenhouse, and camphor trees are planted in large flower pots and then raised by the present invention. The two conditions are in the same environment. The amber silkworm larvae are raised normally to form cocoons, and the cocoons are cut open 7 days after the cocooning is completed. The pupae are weighed after distinguishing male and female pupae by the morphology of the genitals and antennae.

[0073] Test results: The above test results show that the weight of male and female pupae raised in ordinary storage boxes is lower than that of the feeding method of the present invention to a certain extent in different groups. Both methods are raised under the same conditions, and the weight of the pupae is related to the growth and development of the larvae, the nutrient content of the host and the amount of food consumed. When the storage box is used for breeding, the leaves are easy to wilt, and the larvae do not have good nutritional supplements when feeding. The state is worse than that of the method of the present invention, resulting in a relatively low weight of the pupae. In general, the amber silkworms raised by the method of the present invention have heavier pupae weight, and the larvae take in more nutrition and are healthier. In the wild, the amber silkworms can ensure that they always eat fresh leaves when feeding, while the present invention is a breeding method that feeds fresh leaves. The weight of the pupa is related to the egg-laying amount of the adult and the health of the offspring to a certain extent, so the present invention can better reflect the actual situation of the amber silkworms in the wild.

[0077] Effects of different feeding methods and leaf replacement on the loss rate of amber silkworm larvae

[0078] The amber silkworms and silkworm eggs disinfection methods, greenhouse conditions and other operating methods are the same as those in Example 3. Condition 1 is set as inserting camphor tree branches into a water bottle, placing them in a storage box for feeding, feeding them in a large greenhouse, and regularly replacing camphor tree branches; Condition 2 is set as feeding in the same greenhouse, camphor trees are planted in large flower pots and then raised by the present invention. Two conditions in the same environment. Loss rate of 1-3 instar larvae: 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 plant. The age and survival of the larvae are counted every 2 days. When the larvae reach the next instar, the number of remaining larvae is counted. Larvae loss rate (%) = (this instar - the number of silkworms started in the previous instar) / the number of silkworms started in the previous instar.

[0079] Test results: The above test results show that there is basically no loss when amber silkworms are raised in a greenhouse in two different ways. Because when the storage box is used for raising silkworms, the young larvae are prone to lack of water and death due to slow leaf replacement, and their condition gradually deteriorates until death. However, the problem of leaves is almost solved after raising them by the invention. At the same time, the feeding situation of the larvae in the wild is completely simulated, and fresh leaves are fed in time. The device of the present invention effectively solves the problem that the larvae are prone to falling and dying due to other biological and non-biological factors. The side wall of the present invention adopts a gauze structure. The amber silkworm larvae can climb back to the leaves from the gauze after falling. When the storage box is used for raising silkworms, the larvae are difficult to return to the leaves due to the smooth side wall. The loss rate of larvae is also greatly reduced after raising them by the present invention.

9. A method for using the amber silkworm growth and development observation device according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: Plant the host plant of the amber silkworm in a large flower pot, and regularly prune the plant to a height of 1.0-1.5m to ensure its water and nutrients, and prune it to produce more side branches; S2: During feeding observation, the host plant and the flower pot were moved to a greenhouse with the function of maintaining temperature and humidity. The host was cultured in the greenhouse for 10 days before the experiment began. An independent branch was selected and dead and yellow leaves were removed; S3: Take out the universal umbrella rib (6), stretch the telescopic rod (6.1) to 1.5-2.0m, check the universal branch (6.2) and the hanging hole (6.3), insert the telescopic rod (6.1) into the large flower pot for vertical fixed support, and unfold the universal branch (6.2) in all directions above the host plant; insert the lower end of the telescopic rod (6.1) into the soil of the flower pot, the independent stone seat or the vertical rod in the flower pot; if it is difficult to insert and fix, tie the rod strap (6.4) on the base section of the telescopic rod (6.1) to the main stem of the host plant for fixing; S4: pulling open the elastic binding wire (1.1) on the compressed three-dimensional mesh cover (1), so that the three-dimensional mesh cover (1) automatically springs open under the elastic force of the spring support rod (3), and the interior of the three-dimensional mesh cover (1) is expanded into a three-dimensional space structure; S5: Put the three-dimensional net cover (1) on the independent branch with tender leaves, pull the two ends of the closing line (5.1), use the closing line (5.1) to tighten the shrink sleeve (5) and then tie a knot; S6: After a plurality of three-dimensional net covers (1) used for feeding are put on branches, a thin rope is used to connect the hanging hole (6.3) on the universal umbrella rib (6) and the net cover hook (2.1), so that the branches are not subjected to force and the three-dimensional net covers (1) are in a hanging state; S7: Open the zipper door (4), transfer the newly hatched amber silkworm larvae to the leaves in the three-dimensional net cover (1), and close the zipper door (4); S8: Observe the growth of the amber silkworm larvae through the transparent observation window (2) every day. When the larvae are in the 1st to 3rd instar, there is no need to change the branches for feeding. Every 4 to 6 days, open the zipper door (4) and pour out the feces from the zipper door (4). When the larvae are in the 4th to 5th instar, change the branches every 3 to 5 days and pour out the feces in the device at the same time. S9: Number the outside of each single-headed amber silkworm larvae device to distinguish them, and record the changes in their age when observing the growth of the amber silkworm larvae every day. Record once a day until the amber silkworm spins silk and forms a cocoon, then take out the cocoon, remove the three-dimensional net cover (1) and the universal umbrella rib (6); S10: When folding, the three-dimensional mesh cover (1) is compressed, and after compression, the elastic binding wire (1.1) is used to surround the shrink sleeve (5) to compress the spring support rod (3), and the three-dimensional mesh cover (1) is stacked and folded; the universal branch (6.2) and the telescopic rod (6.1) are tied closely together.
