Description

Technical Field

[0001] The utility model relates to the technical field of artificial breeding of Spodoptera frugiperda, in particular to an egg collection device for artificially breeding Spodoptera frugiperda. Background Technique

[0002] Spodoptera frugiperda belongs to Noctuidae of Lepidoptera, and is a major migratory pest native to tropical and subtropical regions of the Americas. It has the characteristics of a wide host range, strong reproductive ability, and fast diffusion speed. It invaded Yunnan Province of China in 2019 and has currently spread to damage crops in 18 provinces across the country. Efficient breeding of this insect is conducive to developing effective biological control measures.

[0003] At present, Trichogramma ostriniae used for controlling Spodoptera frugiperda has become a hot topic. Trichogramma ostriniae is an important parasitic natural enemy in the egg stage of Noctuidae pests of Lepidoptera and is also a dominant natural enemy insect. It has a very strong parasitic ability on the eggs of pests such as Spodoptera litura, Spodoptera exigua, Helicoverpa assulta, Spodoptera frugiperda, and Mythimna separata.

[0004] Spodoptera exigua and Spodoptera litura are very prone to degeneration after being artificially bred indoors for several generations. There are many reasons, mainly because they are easily infected with granulosis virus, which leads to the obstruction of population breeding. Spodoptera frugiperda has a strong reproductive ability and is not easily interfered by viruses, and has great advantages in artificial breeding. Improving the artificial breeding efficiency of Spodoptera frugiperda is conducive to reducing the breeding cost of Trichogramma ostriniae, and thus conducive to improving the efficiency of using natural enemy insects to control pests.

Installation blocks are installed on the top ends of the support plates, and an electric push rod is installed on one side of each installation block. One end of the electric push rod is installed on the outer surface of the frame body. A placement tray is placed inside the placement table.

[0007] Preferably, a connecting plate is installed inside the inner box body, and a fixing plate is installed at one end of the connecting plate.

[0008] Preferably, the fixing plate is arc-shaped, and the inner wall of the fixing plate is installed on the outer surface of the frame body.

[0009] Preferably, both of the sliding surfaces are arc-shaped, and the two sliding surfaces are respectively slidably connected to the outer surfaces of the corresponding frame bodies.

[0010] Preferably, one end of the inner box body is open, and the inner box body is a solid frame.

[0011] Preferably, the opening is circular or oval in shape.

[0012] Preferably, the frame body is composed of twelve pipe bodies, and the twelve pipe bodies can be plastic pipes or steel pipes.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Under the operation of the electric push rod, the mounting block and the support plate can move towards the opening, so that the placement table can move accordingly. As a result, the two sliding rods can slide on the outer surfaces of the corresponding frame bodies through the corresponding sliding surfaces respectively, and the placement tray placed inside the placement table can move accordingly.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As shown in Figures 1 - 3 the figure, it includes an outer box body 1. The outer box body 1 is a cuboid box body with dimensions of 80 cm * 40 cm * 60 cm. A frame body 11 is installed inside the outer box body 1, and an opening 12 is provided on one inner wall of the outer box body 1. The frame body 11 is composed of twelve groups of pipe bodies, and the twelve groups of pipe bodies can be plastic pipes or steel pipes. The outer box body 1 is supported by the frame body 11 and is enclosed by a screen or a plastic board. An egg collection cloth is arranged on the surface of the frame body 11. The frame body 11 can be a plastic pipe or a steel pipe and is used to fix the egg-laying cloth. The shape of the opening 12 is set as circular or elliptical. A shielding cloth 13 is installed inside the opening 12, and a zipper 14 is arranged on the surface of the shielding cloth 13. The opening diameter of the opening 12 ranges from 5 cm to 20 cm, allowing one to reach in to take the egg masses and supplement the food and water for the fall armyworm. On one side of the inner bottom wall of the outer box body 1, an inner box body 2 is installed, and on the other side of the inner bottom wall of the outer box body 1, a placement table 3 is placed movably. The inner box body 2 is a cuboid box body with dimensions of 30 cm * 20 cm * 20 cm. One end of the inner box body 2 is open, and the inner box body 2 is provided with a solid frame. A connecting plate 21 is installed inside the inner box body 2, and a fixing plate 22 is installed at one end of the connecting plate 21. The shape of the fixing plate 22 is arc-shaped, and the inner wall of the fixing plate 22 is installed on the outer surface of the frame body 11, so that the inner box body 2 can be stably fixed inside the outer box body 1. The inner box body 2 can be a solid frame or transparent, mainly used for the fall armyworm to inhabit. Small pieces of egg-laying cloth can be placed above to fully collect the egg masses of the fall armyworm. The skeleton of the inner box body 2 can be plastic or steel pipe.

[0021] Support plates 31 are installed on the side surface of the placement table 3, and sliding rods 32 are installed on both sides of the support plates 31. Sliding surfaces 33 are arranged on the end faces of the sliding rods 32. Both groups of sliding surfaces 33 are arc-shaped surfaces, and the two groups of sliding surfaces 33 are respectively slidably connected to the outer surfaces of the corresponding frame bodies 11. Installation blocks 34 are installed at the tops of the support plates 31, and electric push rods 35 are installed on one side of the installation blocks 34. One end of the electric push rod 35 is installed on the outer surface of the frame body 11. A placement tray 36 is placed inside the placement table 3. The placement tray 36 can hold liquids or solids. The placement tray 36 can be a porcelain tray, a plastic tray, or a steel tray, mainly used for placing honey and water to supply the daily feeding needs of the fall armyworm adults, extend the egg-laying period, and increase the yield.

[0022] During use, when it is necessary to replace the food inside the placement tray 36, the user can start the electric push rod 35. Thus, under the operation of the electric push rod 35, the mounting block 34 and the support plate 31 can move towards the opening 12, so that the placement table 3 can move accordingly. As a result, the two sliding rods 32 respectively slide on the outer surface of the corresponding frame body 11 through the corresponding sliding surfaces 33, so that the placement tray 36 placed inside the placement table 3 can move accordingly. When the placement tray 36 moves to a position on one side of the opening 12, the operation of the electric push rod 35 can be stopped. At this time, the user can open the shielding cloth 13 through the zipper 14. Thus, the user can reach into the inner part of the outer box body 1 through the shielding cloth 13 and the opening 12, and perform the operation of taking the placement tray 36, so as to replace the food inside the placement tray 36. After replacement, according to the above operations, the reverse operation can be performed to move the placement table 3 and the placement tray 36 to the initial position, so as to supply the daily feeding requirements of the Spodoptera frugiperda adults.

[0023] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
