[0029] To make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme of the utility model will be described clearly and completely below in combination with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0030] Embodiment 1

[0031] The utility model embodiment provides a trichoplusia ni egg card device, including egg sac board and suspension egg card.

[0032] As Figures 1-5 Indicated, wherein the egg sac board includes egg sac base plate 1 and 24 egg sac bubble cover 2, egg sac base plate 1 adopts the Dupont paper of the grammage 55±2g / m 2 The egg sac bubble cover 2 is transparent, is the degradable bubble cover board made of transparent polylactic acid (PLA), and the thickness is 0.35mm, and the light transmittance is greater than or equal to 90%.

[0033] As Figures 1-2 Indicated, the egg sac base plate 1 is provided with indentation tear line 3, and the indentation tear line 3 includes 5 horizontal tear lines and 3 vertical tear lines, and the 5 horizontal tear lines and 3 vertical tear lines are equidistantly arranged respectively, and the horizontal tear line and the vertical tear line are crossed distribution, and the egg sac base plate 1 is divided into the segmentation plate 4 consistent with the number (24) of egg sac bubble cover 2, and the segmentation plate 4 is square, and the diameter of egg sac bubble cover 2 is less than the side length of segmentation plate 4, and the center of egg sac bubble cover 2 coincides with the center of segmentation plate 4.

[0034] As Figures 1-2 Indicated, each egg sac bubble cover 2 is fixedly connected with each segmentation plate 4 surface through heat sealing process, forms several closed egg sac chambers for accommodating trichoplusia ni eggs, and the segmentation plate 4 adopts Dupont paper and has the air-permeable waterproof performance, and the water vapor can be permeated, can provide suitable humidity, prevents external liquid water from entering, and ensures the hatching rate of trichoplusia ni eggs. Insect eggs 5 are arranged in the egg sac chamber, and the egg sac chamber is transparent, and the hatching condition of insect eggs can be observed conveniently.

[0035] In the embodiment, tear lines are arranged between each egg sac bubble cover 2, so that the egg sac can be conveniently torn off when used. The segmentation plate 4 is provided with a rectangular easy-to-tear opening 8, which is convenient to open and release the hatched trichoplusia ni larvae.

[0036] As Figures 3-5As shown, the hanging egg card is provided with an egg sac mounting hole 6 for fixing the egg sac, and the diameter of the egg sac mounting hole 6 is smaller than the side length of the partition plate 4. Three protrusions 7 are arranged in the egg sac mounting hole 6 and are equidistantly distributed along the inner wall of the egg sac mounting hole 6. More specifically, the protrusions 7 are springs, and the ends of the springs are fixedly connected with the inner wall of the egg sac mounting hole 6. When the egg sac bubble cover 2 is inserted into the egg sac mounting hole 6, the spring can generate pressure on the egg sac bubble cover 2 to clamp and fix the same, so as to avoid falling off. In other embodiments of the utility model, in order to cooperate with the protrusions 7, an inner groove matched with the protrusions 7 can be arranged on the egg sac bubble cover 2 close to the partition plate 4. When the egg sac bubble cover 2 is inserted into the egg sac mounting hole 6, the protrusion 7 (spring) is correspondingly positioned with the inner groove, and the spring enters the inner groove under the action of elastic potential energy, so that the egg sac bubble cover 2 and the partition plate 4 can be clamped and fixed at the egg sac mounting hole 6, and falling off can be avoided.

[0037] As shown in the drawings, Figures 3-5 The hanging egg card is provided with a hanging hole and a strip-shaped hole. The strip-shaped hole is arranged on one side of the hanging hole, one end of the strip-shaped hole is communicated with the hanging hole, the other end is communicated with the outside, the strip-shaped hole is arranged obliquely downward, and a hanging hook structure which is not easy to fall off is formed, so that the egg can be placed in a place where it is not easy to be placed or a high position of a plant.

[0038] The application process of the utility model is as shown in the drawings, Figure 6 Specifically includes:

[0039] The partition plate 4 provided with one egg sac bubble cover 2 is torn off through the indentation tear line 3;

[0040] The egg sac bubble cover 2 on the torn partition plate 4 is arranged in the egg sac mounting hole 6 of the hanging egg card, and the egg sac bubble cover 2 is fixed through the protrusion 7, so that the egg sac bubble cover 2 and the partition plate 4 are stably fixed at the egg sac mounting hole 6;

[0041] After the fixing is completed, the easy-to-tear opening 8 on the back of the partition plate 4 is torn (or the easy-to-tear opening 8 on the back of the partition plate 4 is torn after it is observed that the larva of the green lacewing is hatched), and the hanging egg is hung at a suitable position. The larva can crawl out through the tear opening, find the pests, and play a biological control function.

[0042] Embodiment 2

[0043] The main body structure of this embodiment is the same as that of embodiment 1, and the difference lies in that the structure of the protrusion 7 is different.

[0044] In this embodiment, the protrusion 7 is a telescopic rod structure, which comprises an inner fixed rod 9 and an outer movable rod 10. The end of the inner fixed rod 9 is fixedly connected with the inner wall of the egg sac mounting hole 6, and the outer movable rod 10 is hollow inside and is sleeved outside the inner fixed rod 9 and can move linearly relative to the inner fixed rod 9.

[0045] More specifically, the inner fixed rod 9 is provided with an axial distribution of sliding grooves on its outer surface, and the outer movable rod 10 is provided with sliding blocks corresponding to the sliding grooves on its inner surface. The outer movable rod 10 is connected with the inner fixed rod 9 through the sliding grooves and the sliding blocks, and there is a certain friction between the outer movable rod 10 and the inner fixed rod 9. In addition, the outer movable rod 10 is provided with a tab 11 on its outer surface towards one end of the inner wall of the egg sac mounting hole 6, which facilitates the manual adjustment of the linear movement of the outer movable rod 10.

[0046] In this embodiment, the egg sac bubble cover 2 is provided with an inner groove corresponding to the telescopic rod structure near the position of the partition plate 4. When the egg sac bubble cover 2 is inserted into the egg sac mounting hole 6, the telescopic rod structure corresponds to the position of the inner groove.

[0047] In application, the egg sac bubble cover 2 on the torn partition plate 4 is placed into the egg sac mounting hole 6 on the hanging egg card, at this time the telescopic rod structure corresponds to the position of the inner groove, and the outer movable rod 10 is manually (or through tools) driven by the tab 11 to move towards the egg sac bubble cover 2 (i.e. the length of the telescopic rod structure becomes longer), until the outer movable rod 10 enters the inner groove of the egg sac bubble cover 2, so as to fix the egg sac bubble cover 2 and the partition plate 4 at the egg sac mounting hole 6, avoiding falling off.

[0048] When the insect eggs in the egg sac bubble cover 2 are hatched and released, the outer movable rod 10 is driven by the tab 11 to move away from the egg sac bubble cover 2 (i.e. the length of the telescopic rod structure becomes shorter), so that the outer movable rod 10 is separated from the inner groove of the egg sac bubble cover 2, facilitating the removal of the egg sac bubble cover 2 and the partition plate 4 after the release from the hanging egg card, and the hanging egg card can load the next egg sac bubble cover 2 for cyclic application.

[0049] The above is only the preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that some improvements and decorations without departing from the principle of the present application are considered as the protection scope of the present application.
