Description

Technical Field

[0001] The utility model relates to the technical field of larval propagation components, in particular to a breeding tray for automated large-scale production of noctuid larvae. Background Art

[0002] Most of the armyworms are herbivorous pests and are important pests worldwide. In order to reduce the damage of armyworms to crops and achieve effective control of armyworms, it is necessary to study the large-scale propagation technology of the egg parasitoid of the armyworm, the black egg wasp of the armyworm. The propagation of the black egg wasp of the armyworm requires a large number of armyworm eggs. Therefore, it is urgent to make a breakthrough in the large-scale propagation technology of the armyworm.

[0003] When breeding noctuid insects, it is necessary to use trays suitable for automated large-scale production. The existing trays, such as the patent document with the announcement number "CN 210202974 U", mention a feeding tray, which has 25 independent feeding holes formed on a main body. When feeding, feed and eggs or larvae are placed in the feeding holes and then sealed. It has the following disadvantages:

[0004] Eggs and larvae are different forms of noctuids at different stages. The parameters of the living environment (temperature, humidity, light, oxygen content, etc.) required for the two during their growth are not the same. The eggs and larvae are placed in the feeding holes with artificial feed, which is the most suitable environment for the larvae, but not for the eggs. The eggs are in direct contact with the artificial feed of the larvae, and the humidity, temperature, preservatives and pH value in the feed will have a negative impact on the eggs, which in turn affects the hatching rate of the eggs and causes a decrease in feeding efficiency.

[0005] In order to keep the eggs and larvae of noctuid insects in the most suitable living environment for production and development, different production environments need to be set for eggs and larvae. In addition, in the prior art, during the feeding process, the feeding tray needs to place feeding materials suitable for the eggs in the feeding holes, and in the later larval stage, the feeding materials suitable for the larvae need to be replaced. When replacing the feeding materials, the seal on the tray needs to be removed. This process, on the one hand, will lead to the complexity of the expansion process, and on the other hand, during the process of removing the seal and replacing the feeding materials, it will lead to the possibility of larvae escaping, and further, it will prolong the expansion cycle.

[0006] Therefore, how to provide a breeding tray for automated large-scale production of noctuid larvae that can avoid the above-mentioned disadvantages has become a technical problem that technicians in this field urgently need to solve. Summary of the invention

[0007] To achieve the above purpose, the utility model provides a feeding tray for automated large-scale production of noctuid larvae, which can provide the optimal living environment for eggs and larvae at different growth stages for automated feeding, and only requires one-time addition of feeding materials and subsequent film sealing, which greatly improves the efficiency of expansion and can reduce costs and shorten the feeding cycle.
