Technical Field
[0001] The utility model relates to the technical field of aphid breeding and plant anti-aphid phenotype investigation, in particular to an aphid breeding device. Background Art
[0002] Aphids, commonly known as sticky insects, belong to the superfamily Aphidoidea of the order Hemiptera of the class Insecta and are one of the main pests that damage cotton yield and quality in my country. Aphids have strong vitality and adaptability and can survive in a variety of complex environments. Due to their strong reproductive capacity, rich species and wide distribution, aphids have become one of the most destructive phloem pests in the world.
[0003] Aphids mainly gather on the back of young leaves and stem tips of plants, using specialized mouthparts to pierce the plants to suck sap, which causes the growth of leaf buds and lateral buds on the top of the plants to be stunted, or even shrink and deform, thus affecting the yield and quality of crops, and bringing serious economic pressure to growers. In addition, aphids are also virus vectors, transmitting diseased plant viruses to healthy plants in the process of sucking sap. At the same time, the honeydew excreted by aphids can cause damage to host plants, such as blocking leaf stomata, inducing mold growth, etc., affecting plant photosynthesis. Therefore, how to effectively prevent and control aphids has become one of the major problems facing agricultural workers today.
[0004] Breeding aphid-resistant varieties is considered to be the most effective way to prevent and control aphids and reduce crop losses. How to breed aphid-resistant varieties and locate effective insect-resistant target genes, the first task is to screen and grade aphid-resistant varieties, and then conduct statistical analysis on aphid-resistant related quantitative traits. When investigating the aphid-resistant phenotype of plants in natural environments, as the temperature continues to rise, aphids often occur in spots, which has a great impact on the accuracy of the survey results. When investigating the aphid-resistant phenotype of plants under field conditions, it is often necessary to count a large number of individual plants, and to count the number of aphids occurring on the entire plant, which is a huge workload.
[0005] Most of the existing aphid rearing devices are suitable for indoor use. For aphid rearing devices that use culture dishes to rear aphids, fresh plant leaves need to be frequently replaced. Secondly, when observing the reproduction of aphids, it is inconvenient to open the cover and observe and record on the back of the leaves. For the rearing devices that use the whole plant to seal the nutrient solution, there are problems such as high rearing cost, inconvenience in carrying, and not suitable for large-scale outdoor aphid surveys. They are only suitable for indoor use during the seedling stage.

[0026] The utility model aims to provide an aphid breeding device to solve the problems existing in the prior art. The device can be connected to a living plant in a natural environment, and aphids can be directly fed on leaves of living plants, which is closer to the actual growth environment of aphids. Compared with the traditional feeding method, the leaf replacement step is reduced, and the breeding cost is reduced.

A transparent observation part is arranged on the breeding box, which is also convenient for observing the molting and aphid production of aphids fed on the front and back of the leaf, thereby improving the efficiency of plant anti-aphid phenotype investigation and being easy to carry.
[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] like Figure 1 As shown, the present embodiment provides an aphid breeding device 100, comprising a breeding box 1, the top of which is provided with an opening, and the breeding box 1 can be sleeved on a living plant leaf 01 through the opening to breed aphids 02; the breeding box 1 is also provided with a sealing portion, an insect-proof ventilation portion and a transparent observation portion, the sealing portion is used to seal the opening, and to make the opening and the petiole of the living plant leaf 01 be clamped and fixed; the insect-proof ventilation portion is used to allow the air in the breeding box 1 to circulate with the outside air, and to prevent the natural enemies of aphids from the outside from entering the breeding box 1; the transparent observation portion is used to transmit light, so that the living plant leaf 01 in the breeding box 1 can perform photosynthesis, and the molting and reproduction of the aphids 02 in the breeding box 1 can be observed and recorded through the transparent observation portion.
[0029] In this embodiment, if Figure 2 As shown, the upper part of the feeding box 1 is a triangular prism structure, and an isolation buffer zone is formed inside the triangular prism structure for accommodating the petiole part of the living plant leaf 01; Figure 3As shown, the lower part of the breeding box 1 is a cubic structure, and an aphid breeding area is formed inside the cubic structure to accommodate living plant leaves 01 and aphids 02; as for the size of the breeding box 1, those skilled in the art can design it according to the size of the selected target leaves.
[0030] In this embodiment, the opening of the feeding box 1 is a strip opening 2, which extends along the top side edge of the triangular prism structure; the sealing part is a finger pressure concave-convex buckle 3, which is arranged on the strip opening 2, and a circular bayonet 4 is formed in the middle of the finger pressure concave-convex buckle 3, and a sealing layer is provided in the inner circle of the circular bayonet 4, and the sealing layer in this embodiment is preferably a cotton wool sealing layer; when the feeding box 1 is sleeved on the living plant leaf 01 through the strip opening 2 and the finger pressure concave-convex buckle 3 is pressed, the circular bayonet 4 is clamped and fixed with the petiole of the living plant leaf 01, and the sealing layer is fitted with the petiole of the living plant leaf 01 to seal the circular bayonet 4, so that a closed feeding space is formed in the feeding box 1 to prevent the aphids 02 from escaping; the finger pressure concave-convex buckle 3 is a mature existing technology, and those skilled in the art can choose it according to needs, and the function of freely opening and closing the finger pressure concave-convex buckle 3 is used to facilitate the clamping of the petiole of the living plant leaf 01 and the removal of the aphids 02 in the feeding box 1.
[0031] In this embodiment, the frame of the triangular prism structure and the frame of the cubic structure are both soft plastic frames 5. Specifically, the soft plastic frame 5 is connected by 12 soft plastic support rods, providing a hollow long cubic space structure for the breeding of aphids 02, avoiding direct contact between the inner wall of the breeding box 1 and the living plant leaves 01; the four side surfaces of the triangular prism structure and the front side surface, rear side surface and bottom surface of the cubic structure are all transparent polyethylene plates 6, forming a transparent observation part; the left side and right side surfaces of the cubic structure are both 60-mesh screens 7, forming an insect-proof ventilation part, and the screens 7 opened on both sides ensure that there is sufficient fresh air circulation in the aphid breeding area, and also reduce the condensation of water vapor on the transparent polyethylene plate 6. At the same time, it can prevent the damage of external natural enemies to aphids 02.
[0032] Furthermore, a drying layer is provided on the inner wall of the side of the triangular prism structure, and the drying layer is used to absorb water vapor in the breeding box 1; specifically, the drying layer in this embodiment is preferably a cotton wool drying layer 8, and the cotton wool sealing layer at the circular snap-in 4 of the finger-pressed concave-convex buckle 3 can effectively absorb a small amount of water vapor generated by transpiration and photosynthesis of the living plant leaves 01 in the breeding box 1, so as to keep the internal environment of the entire device dry and comfortable, and further optimize the living environment of the aphids 02.
[0033] The use process and working principle of this device are as follows:
[0034] like Figure 4As shown, first, select a suitable living plant leaf 01 as the target leaf, use a small brush to inoculate the newly laid aphids on the target leaf, put the strip mouth 2 of the device on the petiole of the target leaf, and press the finger-pressed concave-convex buckle 3 to complete the connection between the device and the living plant, then record the molting and reproductive period profile of the aphid 02 every 12 hours until the fed individual dies, and the relevant data can be used to study the aphid bisexual life table of aphid 02 in this variety, predict the population growth rate and evaluate the resistance of this variety to aphid 02.
[0035] During the reproduction process of aphids 02, aphids 02 will react to the intensity of light and climb to the back or front of leaves. Since the front and back sides of the aphid breeding area of the device are made of transparent polyethylene material (LDPE), which has a high degree of light transmittance, the staff can well observe and record the molting and reproduction of aphids 02. If aphids 02 are attached to the back of the leaf, it is only necessary to gently reverse the device, which will not disturb the aphids 02 and cause them to fall, nor will it cause damage to the leaves; the sieves 7 on both sides of the aphid breeding area effectively maintain the flow of fresh air in the breeding box 1, while blocking the intrusion of aphids' natural enemies under natural conditions, and preventing the aphids 02 from escaping; the water vapor generated by transpiration and photosynthesis on the leaves in the breeding box 1 will move upward, and the absorbent cotton drying layers 8 on both sides of the isolation buffer zone and the absorbent cotton sealing layers at the circular bayonet 4 of the finger-pressing concave-convex buckle 3 can effectively absorb this part of the water vapor, prevent moisture accumulation, and provide a suitable and safe internal environment for the growth of aphids 02.
[0036] In summary, the device can be connected to living plants in a natural environment, and aphids 02 can be directly fed on leaves 01 of living plants, which is closer to the actual growth environment of aphids 02. Compared with the traditional feeding method, the leaf replacement step is reduced, and the feeding cost is reduced. In addition, the aphids 02 can be restricted to the range of a leaf through the feeding box 1, which is convenient for counting. The transparent observation part provided on the feeding box 1 is also convenient for observing the molting and aphid production of aphids 02 raised on the front and back of the leaf, which improves the efficiency of plant anti-aphid phenotype investigation and is easy to carry. The device is a portable feeding device that can be widely used for aphid feeding and population reproduction observation in greenhouses and natural environments, and can also be used as a temporary storage device for capturing and collecting insect samples in the wild.
[0037] The present invention uses specific examples to illustrate the principle and implementation of the present invention. The above examples are only used to help understand the method and core idea of the present invention. At the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
