Embodiment 1
[0125]Example 1 Optimization of artificial feed components
[0126]Prepare artificial feed according to the following formula, where, unless otherwise specified, the unit of each component is g:
[0131]1. According to the prescription, weigh the agar powder, add it to 1700ml of water, stir to dissolve and cook in a pressure cooker for 1 hour;
[0132]2. Add 750ml of water to the water bath and start heating. Weigh the soybean flour, wheat germ, yeast powder and casein that have been baked at 120°C for 2 hours. Mix the powders evenly. After the water in the water bath boils, add the agar solution in step 1 and weigh it. Stir constantly, cook for 50 minutes and then cool down;
[0133]3. Weigh potassium sorbate, methyl par...
Embodiment 2
[0142]Example 2 Feeding experiment of Noctuidae
[0143]Use the formulated feed to feed Noctuidae, and the feeding conditions are as follows:
[0144]The noctuid larvae are placed in an insect breeding room, the temperature of the insect breeding room is controlled at (26±1)°C, the relative humidity is 60%-70%, and the light conditions are L14:D10 to allow the larvae to grow naturally. During the developmental stage of the 1-3 instar larvae of Noctuidae, it is fed in groups, feeding 1-2 times a day; the obtained artificial feed has a thickness of 0.5 cm, a width of 5 cm and a length of 8 cm. During the developmental stage of the 3-6 instar larvae of Noctuidae, single-head feeding is used. The artificial feed slices obtained are about 1cm thick, 2cm wide, and 4cm long. One insect feeds one piece, and the feed is changed after it is exhausted. The photos of feed moldy in 20 days are attachedfigure 2 As shown in the figure, it can be seen that the feed of the present invention did not develo...

Abstract
The invention relates to an automatic production line and an automatic production method for large-scale expanding propagation of noctuid larvae. The automatic production line for large-scale expanding propagation of the noctuid larvae comprises a conveying device, a feed filling device which is used for filling noctuid feed into feeding holes of noctuid feeding trays, a cooling device which is used for cooling the noctuid feeding trays filled with the noctuid feed to a preset temperature, a noctuid larva sub-packaging device which is used for uniformly mixing the noctuid larvae with a mediumto form a noctuid larva sub-packaging material and quantitatively putting the noctuid larva sub-packaging material into the feeding holes of the noctuid feeding trays, and a sealing device which is used for pasting sealing films with air holes on the noctuid feeding trays so as to seal the feeding holes, wherein the feed filling device, the cooling device, the noctuid larva sub-packaging device and the sealing device are sequentially distributed in the front-back direction of the automatic production line for large-scale expanding propagation of the noctuid larvae. According to the automatic production line for large-scale expanding propagation of the noctuid larvae, the automation degree of noctuid larva subpackaging is improved, and the subpackaging efficiency is improved.
Description
Technical field[0001]The invention relates to the field of noctuid breeding, in particular to an automated production line and an automated production method for the large-scale propagation of noctuid larvae.Background technique[0002]The statements here only provide background information related to this application, and do not necessarily constitute prior art.[0003]Noctuid moths are mostly herbivorous pests and are important worldwide pests. In order to reduce the damage of the armyworm to the crops and realize the effective control of the armyworm, the project team conducted research on the large-scale propagation technology of armyworm's egg parasitoid-armyworm black egg wasp. Reproduction requires a large number of noctuid eggs. Therefore, it is urgent to make breakthroughs in the technology of large-scale propagation of Noctuidae.[0004]Noctuid larvae have the habit of killing each other, so they are mostly raised with a single head during the feeding process. For example, one w...
