Description

Technical Field

[0001] This utility model relates to the field of insect rearing devices, and more specifically, to a device for efficiently rearing sweet potato weevils. Background Technology

[0002] The sweet potato weevil, also known as the sweet potato ant weevil, primarily damages Convolvulaceae plants and is a significant quarantine pest both domestically and internationally. This pest is small in size, conceals its damage, has a high reproductive rate, and adults have a long lifespan. Adults exhibit significant feigning death, and generational overlap is severe. In recent years, due to extensive planting and management practices by sweet potato farmers, resulting in exposed potato stems, coupled with climatic factors, the occurrence of the sweet potato weevil has become more complex and severe. Furthermore, with the continuous development of the sweet potato industry and the increasing frequency of seed potato trade, the damage caused by the sweet potato weevil has become more serious, showing a continued trend of spreading and seriously affecting the safe and sustainable development of my country's sweet potato industry.

[0003] Currently, both domestic and international efforts are underway to monitor drug resistance in sweet potato weevils and screen control agents. These efforts require that the developmental stages of the sweet potato weevil (including instar, age, individual size, and susceptibility) be as consistent as possible. To achieve this and ensure the accuracy of drug testing results, large-scale artificial rearing is necessary. However, current literature on sweet potato weevil rearing is extremely scarce, and indoor artificial rearing is cumbersome, complex, and difficult. It is not only time-consuming, but the host plants (such as tubers and leaves) are prone to rotting, spoilage, or mold growth, leading to malnutrition and bacterial infections in the larvae, resulting in a high larval mortality rate. Furthermore, excessive humidity in the rearing environment can cause large numbers of adults to die from fungal infections, significantly reducing adult numbers and severely impacting adult lifespan and egg production, creating significant difficulties for the next generation. In addition, the piling up of tubers during rearing can cause many adults to be crushed and killed. Therefore, suitable rearing equipment is a crucial prerequisite for improving the lifespan and egg production of the sweet potato weevil. However, to date, there is no efficient breeding device. Therefore, it is urgent to develop an efficient breeding device for sweet potato weevils in order to solve the problems encountered in the breeding process and to carry out large-scale successive breeding. Therefore, this paper proposes an efficient breeding device for sweet potato weevils. Utility Model Content

[0004] The purpose of this utility model is to address the problems raised in the existing background technology. To achieve the above-mentioned utility model objective, this utility model provides the following technical solution: a device for efficiently raising sweet potato weevils, comprising retaining rings, a triangular base, a central shaft, a support ring, a rearing cage, and a rearing box; the triangular base supports the vertical central shaft, and the triangular base stably supports the central shaft through nested rings; the central shaft is longitudinally located in the middle of the three layers of retaining rings, and the central shaft and the triangular base form a solid support; the support ring connects the three layers of retaining rings longitudinally and the retaining rings in the same layer laterally, and the retaining rings are installed on the support ring.

[0005] As a preferred technical solution of this utility model, the retaining rings are arranged radially in 3 layers around the central shaft, 5mm above the ground, with a 3mm gap between the layers, and 16 retaining rings in each layer, arranged in two circles in a front-back arrangement.

[0006] As a preferred technical solution of this utility model, the retaining ring is a crescent shape made of PE environmentally friendly material with a radius of 5.0cm, and the two retaining rings at the front and back support the two ends of the sweet potato.

[0007] As a preferred technical solution of this utility model, a central shaft and a support ring are placed at the bottom of the insect raising box. The support ring is equipped with 24 semi-transparent retaining rings in 3 layers, forming a 3-layer petal-shaped structure.

[0008] As a preferred technical solution of this utility model, a sweet potato is placed in the two front and rear retaining rings, with both ends of the sweet potato extending out of the retaining rings.

[0009] As a preferred technical solution of this utility model, the triangular base and the central shaft are connected by a nested ring, so that the triangular base can stably support the central shaft.

[0010] As a preferred technical solution of this utility model, a central shaft, a support ring, and a crescent-shaped retaining ring are sequentially installed on the triangular base inside the feeding box.

[0011] As a preferred technical solution of this utility model, 24 fresh sweet potatoes are placed in 24 pairs of crescent-shaped retaining rings, and a sweet potato weevil is attached below the retaining rings.

[0012] As a preferred technical solution of this utility model, the central shaft is 13cm long and has a radius of 4.5cm.

[0013] As a preferred technical solution of this utility model, the insect raising cage is a transparent 120-mesh cube cage with a length × width × height of 50.0cm × 50.0cm × 50.0cm; the insect raising box has a length × width × height of 43.0cm × 28.5cm × 16.0cm, and the box lid has an opening with a length × width of 18.0cm × 15.5cm, which is sealed with 120-mesh mesh.

[0014] Compared with existing technologies, the advantages of this invention are as follows: When collecting egg-laying sweet potato tubers, simply brush away the adult sweet potato weevils with a soft brush, move the entire device into a new rearing box, and cover it with a pre-prepared moist, loose substrate. After 10 days, sweep away the substrate on top of the sweet potatoes, leaving only a thin layer, allowing the adult weevils to emerge smoothly. The components of the device can be flexibly installed and disassembled; the retaining rings are easy to clean and can be reused; and the components are inexpensive. Therefore, this method not only saves materials and costs but also greatly improves the efficiency of raising and replacing sweet potatoes, and is easy to operate.

[0015] This invention allows marking on the rings to facilitate subsequent experiments, and also avoids extensive manual handling by direct burial, thus greatly improving efficiency, preventing egg damage from compression, and ensuring larval hatching.

[0016] This new type of feeding device greatly avoids the frequent occurrence of large numbers of adult insects being crushed to death by the huge sweet potatoes at the bottom of the plant, thus improving the survival rate of adult insects to a certain extent.

[0017] This novel rearing device improves both the survival rate and egg production of adult beetles. Previously, about ten sweet potatoes were simply piled at the bottom of the rearing box before introducing newly emerged adults. However, during rearing and egg production, many adults were often crushed and killed by the large sweet potatoes, severely impacting their lifespan and egg production. Furthermore, frequent manual replacement of the sweet potatoes caused secondary injury to the eggs. The use of the crescent-shaped retaining ring fundamentally solves this problem. The large retaining ring secures both ends of the sweet potato, preventing it from falling and allowing adults to easily climb from the bottom of the rearing box to the surface to feed and lay eggs. Simultaneously, the suspended position of each sweet potato avoids the crushing and death caused by multiple piles of sweet potatoes. In addition, egg production is more even. These factors enable the sweet potato weevil to feed and lay eggs efficiently, thereby improving the survival rate and egg production of adults.

[0018] This invention significantly reduces mechanical damage during the collection of egg-laying sweet potato tubers, avoiding potential damage to eggs caused by tweezers or blindly handling the tubers. The crescent-shaped retaining ring largely solves the problem of mechanical damage; simultaneously, the close proximity of adjacent retaining rings allows adult beetles to freely move, feed, and lay eggs among different tubers, avoiding damage caused by human handling. It also greatly improves the utilization rate of sweet potatoes. Because the sweet potato weevil exhibits strong feigning death behavior, it immediately falls to the ground when disturbed, reducing the adult beetle's feeding and egg-laying efficiency. Therefore, the smooth and free migration of tubers secured by the crescent-shaped retaining ring indirectly improves the survival rate and egg production of adult sweet potato weevils. This invention also avoids the frequent occurrence of larvae being crushed to death due to piled-up sweet potatoes in the rearing box; and prevents the widespread occurrence of unbalanced feeding, uneven egg production, or insufficient egg production.

[0019] Based on the strong tendency of the sweet potato weevil to feign death, this invention uses a low-cost, commercially available retaining ring as a unique component to secure the sweet potato. This prevents the bottom of the container from directly contacting the fresh sweet potato tubers and avoids the tubers piling up at the bottom. Instead, it allows adult sweet potato weevils to freely crawl onto the surface of the fresh tubers to feed and lay eggs, avoiding waste and inefficiency. This significantly improves the survival rate and egg production of adult sweet potato weevils, and increases the utilization rate of the sweet potato tubers. Attached Figure Description

It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Example 1: A device for efficiently raising sweet potato weevils, comprising a retaining ring 1, a triangular base 2, a central shaft 3, a support ring 4, an insect raising cage 5, and an insect raising box 6; the triangular base 2 supports the vertical central shaft 3, and the triangular base 2 stably supports the central shaft 3 through a nested ring 7; the central shaft 3 is located longitudinally in the middle of the three layers of retaining rings 1, and the central shaft 3 and the triangular base 2 form a solid support; the support ring 4 is a structure that connects the three layers of retaining rings 1 longitudinally and the retaining rings 1 in the same layer laterally, and the retaining rings 1 are installed on the support ring 4.

[0027] The retaining rings 1 are arranged radially in 3 layers around the central shaft 3, 5mm off the ground, with a 3mm gap between the layers. Each layer has 16 retaining rings 1, arranged in two circles, one in front and one behind. The retaining rings 1 are crescent-shaped and made of environmentally friendly PE material, with a radius of 5.0cm. The two retaining rings 1 at the front and back support the two ends of the sweet potato.

[0028] A central axis rod 3 and a support ring 4 are placed at the bottom of the insect rearing box 6. The support ring 4 has 24 semi-transparent retaining rings 1 in three layers, forming a three-layer petal-shaped structure. A sweet potato is placed on each of the front and back retaining rings 1, with both ends of the sweet potato extending beyond the retaining rings 1. A triangular base 2 is connected to the central axis rod 3 by a nested ring 7, allowing the triangular base 2 to stably support the central axis rod 3. The central axis rod 3 is 13cm long and has a radius of 4.5cm.

[0029] Inside the feeding box, the central shaft 3, the support ring 4, and the crescent-shaped retaining ring 1 are installed sequentially on the triangular base 2.

[0030] 24 fresh sweet potatoes are placed in 24 pairs of crescent-shaped locking rings 1, and a sweet potato weevil is attached below the locking rings 1.

[0031] The insect rearing cage 5 is a transparent 120-mesh cube cage with a length × width × height of 50.0cm × 50.0cm × 50.0cm; the insect rearing box 6 has a length × width × height of 43.0cm × 28.5cm × 16.0cm, and the box lid has an opening with a length × width of 18.0cm × 15.5cm, which is sealed with a 120-mesh mesh 8.

[0032] Example 2: A device for efficiently raising sweet potato weevils. This device combines a base, a central shaft 3, a support ring 4, and a retaining ring 1 to quickly, easily, and efficiently collect and raise sweet potato weevils. Over the past five months, our laboratory has successfully achieved large-scale breeding of sweet potato weevils using this device, which greatly reduces manual labor and improves the survival rate and egg production of adult sweet potato weevils.

[0033] This device is achieved through the following technical solution: Clamping ring 1: made of PE environmentally friendly material, crescent-shaped, with a radius of 5.0cm. The front and rear clamping rings 1 are used to support and hold the two ends of the sweet potato.

[0034] Triangular base 2: A base used to support the vertical central axis 3, which can stably support the vertical axis through the nested ring 7.

[0035] Central shaft 3: 13cm long, 4.5cm in radius; located longitudinally in the middle of the 3-layer retaining ring 1, forming a sturdy support with the triangular base 2.

[0036] The support ring 4 is a structure in which the three layers of retaining rings 1 are connected longitudinally and the retaining rings 1 in the same layer are connected laterally, and retaining rings 1 are installed on it.

[0037] Arrangement: 5mm off the ground, 3 layers of retaining rings 1 are arranged radially around the central axis rod 3, with a 3mm gap between layers. Each layer has 16 retaining rings 1, arranged in two circles, front and back. Each front and back retaining ring 1 can hold one sweet potato, with both ends of the sweet potato extending out of the retaining ring 1.

[0038] The insect rearing cage 5 is a transparent 120-mesh cube with dimensions of 50.0cm x 50.0cm x 50.0cm. The insect rearing box 6 has dimensions of 43.0cm x 28.5cm x 16.0cm, with an opening of 18.0cm x 15.5cm on the lid, sealed with 120-mesh mesh 8 to maintain air circulation. Rearing conditions: Indoor temperature controlled by air conditioning at 27±1℃, photoperiod 14:10h, relative humidity 70%.

[0039] Working principle: A central axis 3 and a support ring 4 are placed at the bottom of the rearing box 6 for raising sweet potato weevils. The support ring 4 has 24 semi-transparent retaining rings 1 in three layers, forming a three-layered petal-shaped device. A fresh sweet potato is placed in each of these rings. A large number of newly emerged adult sweet potato weevils are guided to the retaining rings 1, allowing them to naturally climb onto the sweet potatoes to feed and lay eggs. Adults of the same age are placed on the retaining rings 1 of the same rearing box 6, and the lid is closed. After about 7 days of rearing, the feeding on the sweet potatoes is observed through the semi-transparent mesh 8 and the rearing box 6. When evenly distributed pinhead-sized holes appear on the surface of the sweet potato, the skin begins to dry, and a large number of adult weevils begin to gather on the walls and lid of the rearing box 6, fresh sweet potatoes are promptly replaced.

[0040] Inside the rearing box, install the central shaft 3, support ring 4, and crescent-shaped retaining ring 1 sequentially on the triangular base 2. Place 24 fresh sweet potatoes into 24 pairs of crescent-shaped retaining rings 1, with a sweet potato weevil attached below each retaining ring 1. Cover the rearing box 6 with the lid. After about 7 days, evenly distributed pinhead-sized pits will appear on the surface of the sweet potatoes, which are traces left by adult sweet potato weevils feeding or laying eggs.

[0041] The above-described method for feeding sweet potato weevils with sweet potatoes is highly efficient, simple, easy to operate, time-saving, and recyclable, resulting in excellent rearing outcomes. When collecting egg-laying sweet potato tubers, simply brush away the adult weevils with a soft brush, transfer the entire device into the new rearing box 6, and cover it with pre-prepared moist, loose substrate. After 10 days, sweep away the substrate on top of the sweet potatoes, leaving only a thin layer to allow the adults to emerge smoothly. The various components of the device can be flexibly installed and disassembled; the retaining ring 1 is easy to clean and can be reused; and the components are inexpensive. Therefore, this method not only saves materials and costs but also greatly improves the efficiency of rearing and replacing sweet potatoes, and is easy to operate. The above-described assembly mode of all components allows for marking on the retaining ring 1, facilitating subsequent experiments; furthermore, the direct burial method avoids extensive manual processing, significantly improving efficiency, preventing egg damage from compression, and ensuring larval hatching.

[0042] The rearing device significantly reduces the frequent occurrence of adult insects being crushed to death by the large sweet potatoes at the bottom, thus improving the survival rate of adults. While increasing the survival rate, the device also increases the egg production of adults. Previously, about ten sweet potatoes were simply piled at the bottom of the rearing box 6, and newly emerged adults were introduced. However, during rearing and egg-laying, many adults were often crushed to death by the large sweet potatoes, severely impacting their lifespan and egg production. Furthermore, frequent manual replacement of the sweet potatoes caused secondary injury to the eggs. The use of the crescent-shaped retaining ring 1 fundamentally solves this problem. The large retaining ring 1 secures both ends of the sweet potato, preventing it from falling and allowing adults to easily climb from the bottom of the rearing box 6 to the surface to feed and lay eggs. Simultaneously, the suspended state of each sweet potato avoids the crushing death caused by multiple sweet potatoes piling up. In addition, egg production is more even. These factors enable the sweet potato weevil to feed and lay eggs efficiently, thereby increasing the survival rate of adults and the number of eggs laid.

[0043] The mechanical damage caused during the collection of egg-laying sweet potato tubers is greatly reduced, avoiding potential damage to eggs caused by tweezers or blindly handling the tubers. The crescent-shaped locking ring 1 largely solves the problem of mechanical damage; simultaneously, the close proximity of adjacent locking rings 1 allows adults to freely move between different tubers, feed, and lay eggs, avoiding damage caused by human handling. This also significantly improves the utilization rate of sweet potatoes. Because the sweet potato weevil exhibits strong feigning death behavior, it immediately falls to the ground when disturbed, reducing the adults' feeding and egg-laying efficiency. Therefore, the smooth and free migration of tubers secured by the crescent-shaped locking ring 1 indirectly improves the survival rate and egg production of adult sweet potato weevils. At the same time, it avoids frequent occurrences of larvae being crushed to death due to piled-up sweet potatoes in the rearing box; and prevents a large number of cases of unbalanced feeding, uneven egg production, or insufficient egg production.

[0044] Based on the strong tendency of the sweet potato weevil to feign death, a low-cost, commercially available locking ring 1 was used as a unique component to secure the sweet potatoes. This prevents the bottom of the box from directly contacting the fresh sweet potato tubers and avoids the tubers piling up at the bottom. Instead, it allows the adult sweet potato weevils to freely climb onto the surface of the fresh tubers to feed and lay eggs, avoiding waste and inefficiency. This significantly improves the survival rate and egg production of the adult sweet potato weevils, and increases the utilization rate of the sweet potato tubers.

[0045] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the utility model, are covered within the scope of the claims of the present utility model.
