Abstract
Description
Technical Field
[0001] This invention relates to the technical field of insect breeding and ecological agriculture, specifically to a method for propagating and pollinating island plants using reed wasps based on the branches of *Symplocos cuspidata*. This method enables the large-scale breeding of three important island pollinating reed wasps, which are then used to pollinate island plants, thereby promoting the restoration of island ecosystems. Background Technology
[0002] Reed wasps are key pollinators for many wild plants, especially those found on islands. However, their natural populations are declining due to habitat destruction, climate change, and the threat of parasitic wasps. Traditional artificial insect breeding techniques, mostly designed for social insects like honeybees, are costly, technically complex, and unsuitable for solitary wasps like reed wasps.
[0003] While existing technologies have reported the use of reeds and bamboo tubes as solitary wasp nests, these materials are not the natural preferred nesting materials for wasps, thus limiting their appeal. Furthermore, their inconsistent sizes make standardized propagation difficult. More importantly, in the unique high-temperature, high-humidity, high-salt, and strong-wind environments of islands, ordinary nesting tubes are easily damaged, and the inside of the tubes is susceptible to attacks from predatory insects such as ants or parasitic wasps, resulting in extremely low success rates. In addition, the lack of a complete technical system encompassing breeding, inspection, collection, transportation, and release into the wild hinders the effective expansion of wasp populations and targeted pollination applications.
[0004] Sea privet (Ceratina taiwanensis) is a typical island plant. This invention discovers that its dried branches serve as natural nesting sites for three key island pollinating insects—the Taiwan sea privet (Ceratina taiwanensis), the green sea privet (Ceratina smaragdula), and the toothed sea privet (Ceratina dentipes). Currently, there are no methods or devices for directly utilizing sea privet branches as artificial nesting tubes. Therefore, how to directly utilize sea privet branches as artificial nesting tubes to construct an efficient, controllable, and large-scale propagation and application system suitable for harsh island environments is a pressing technical challenge in this field, aiming to significantly improve the reproductive success rate of sea privet and the pollination and fruit setting rate of island plants. Summary of the Invention
[0005] In order to overcome the shortcomings of the prior art, the present invention aims to provide a method for the propagation of reed wasps based on the branches of *Scabiosa spp.* and for pollinating island plants. This method is low in cost, easy to operate, highly efficient and stable, and is specifically designed for island environments, so as to greatly improve the reproductive success rate of reed wasps and the pollination and fruit setting rate of island plants.
[0006] The objective of this invention is achieved through the following technical solution:
[0007] A method for the propagation of *Pterocarya stenoptera* wasps and their pollination of island plants based on *Pterocarya stenoptera* branches includes the following steps:
[0008] Construction of the reed wasp breeding device: Construct a support structure that is rainproof, sunshade and ventilated, and place the branches of the tung tree inside the support structure as nest tubes. Multiple stacked nest tubes inside the support structure form a nest tube bundle for the reed wasps to build nests and reproduce.
[0009] Screening for the development of wasps and parasitism by natural enemies: Check whether the nest tubes formed by the sea hibiscus are sealed by wasps, collect the sealed nest tubes, check the development of wasps in the nest tubes and the parasitism by natural enemies, and select nest tubes containing healthy wasps for subsequent introduction to the island and for plant pollination.
[0010] Transport and release of reed wasps: The nest tubes containing healthy reed wasp bodies are transported to the target island and placed on new reed wasp breeding devices to release the reed wasps.
[0011] Furthermore, a rainproof, sunshade, and ventilated support structure is constructed. Branches of the *Pterocarya stenoptera* are placed within this structure as nesting tubes. Multiple stacked nesting tubes within the support structure form a bundle for the *Pterocarya stenoptera* wasps to build nests and reproduce. This includes:
[0012] Fix the anchor rod with an anti-termite coating to the ground. Build a sloping cover on the top of the anchor rod using bolts, creating a sheltered space at the bottom. Install the nest tube box on the anchor rod using connectors, placing it below the sloping cover. Use a cylindrical nest tube box and place it horizontally so that the opening is on the side of the box, facing away from the wind and towards the sun. Bundle multiple tamarisk branches together with cable ties or thin ropes and fill the opening of the nest tube box to form a nest tube bundle.
[0013] Furthermore, the nest box is mounted on the fixing rod using connectors, including:
[0014] The connector consists of two crossbars and several bolts. The two crossbars run parallel through the side of the fixed rod, forming two symmetrical support spaces between them. The two nest tube boxes are placed in the two support spaces respectively. The bolt threads pass through the crossbars and are threaded to the surface of the nest tube box, thus fixing the nest tube box in place.
[0015] Furthermore, before placing the branches of *Scabiosa spp.* within the support structure as nesting tubes, the process also includes:
[0016] Collect healthy, mold-free, and dry branches of the Pittosporum tobira. Cut all the branches to a uniform length, ensuring that the white pith is exposed at the cut to attract reed wasps. Then prune the side branches and protrusions of the branches to ensure they are straight.
[0017] Furthermore, before or after the completion of the bee breeding facility, the following are also included:
[0018] Within a radius of 50 to 100 meters outward from the bee breeding device, various nectar-producing plants with alternating flowering periods are sown or transplanted. The nectar-producing plants are species that bees prefer to visit and that are highly adaptable to the island environment. The nectar-producing plants include Pittosporum tobira, Vitex trifolia, Adenium obesum, Prunus persica, Ivy lichen, and / or Ruellia spp.
[0019] Further, examine whether the nest tubes formed by *Scutellaria barbata* have been sealed by wasps, and collect any sealed nest tubes, including:
[0020] Regularly observe the opening of the brood tubes for any activity by wasps and for any sealing material. If the opening of the brood tube is sealed, it indicates that the wasps have completed nest building. If the white pith at the opening of the brood tube has been drilled with a round hole, it indicates that the wasps have built a nest inside the brood tube. At the end of the wasp breeding season or when more than 80% of the brood tubes in the bundle have been sealed, remove the entire bundle and collect the sealed brood tubes. When collecting, number each sealed brood tube and mark the corresponding date and location. Store the sealed brood tubes in a dark, well-ventilated environment at a temperature of 20℃-25℃.
[0021] Further, the development of wasps and parasitism by natural enemies in the nest tubes were examined, and nest tubes containing healthy wasps were selected for subsequent introduction to the islands and for plant pollination, including:
[0022] Portable X-ray microscopy was used to perform non-destructive testing on the nest tubes. The imaging revealed the development of the wasps and the extent of parasitism by predators within the nest tubes. Nest tubes infested with wasps were removed, leaving only those containing healthy wasps.
[0023] Furthermore, the nest tubes containing healthy wasp bodies are transported to the target island, including:
[0024] The nest tubes containing healthy wasp bodies are placed in a transport box and transported to the target island. The opening of the transport box is located on the side, and the opening of the transport box is equipped with a transparent lid that can be opened and closed via hinges or hinges. Both the inner wall of the transport box and the transparent lid are equipped with ventilation holes. The surface of the transport box is made of a supportive plastic material, and the inner bottom of the transport box is equipped with a foam board for cushioning and shock absorption.
[0025] Furthermore, the release of the wasps is carried out by placing them on a new wasp breeding device, including:
[0026] After transporting the nest tube containing healthy wasp bodies to the target island using a transport box, the same wasp breeding device is built on the target island using the method described above. Then, the nest tube containing healthy wasp bodies in the transport box is transferred to the wasp breeding device to release the wasps; or, the transparent lid of the transport box is opened to release the wasps.
[0027] The present invention has the following beneficial effects:
[0028] 1. Highly targeted and efficient: Directly using branches of *Symplocos cuspidata*, which are preferred by bees, results in strong attraction and a high success rate in nest building.
[0029] 2. Environmental adaptability: The special device is designed to take into full account the harsh environment of the island, providing rain protection, sunshade, and ventilation, effectively ensuring the stability of the microenvironment inside the hive tube and greatly improving the survival rate of young bees.
[0030] 3. Quality control: The introduction of non-destructive X-ray detection technology can accurately remove parasitized nest tubes, ensuring the health and quality of the released bee colony, which is impossible to achieve with traditional methods.
[0031] 4. Systematic and operable: It provides a complete set of standardized processes from breeding site construction, bee colony breeding, health screening, long-distance transportation to wild colonization. The methods are simple and easy to promote, making them particularly suitable for application in island reserves or agricultural projects.
[0032] 5. Eco-friendly: The entire process aims to promote pollination of local plants and ecological restoration, without introducing alien species, and the materials and methods used are all environmentally friendly. Attached Figure Description

Detailed Implementation
[0039] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Terms such as “upper,” “inner,” “middle,” “left,” “right,” and “one” used in this specification are merely for clarity of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.
[0040] A method for the propagation of reed wasps and their pollination of island plants based on the branches of *Scabiosa spp.* Figures 1 to 5 As shown, the following methods are included:
[0041] S10: Construction of the reed wasp breeding device: Construct a support structure that is rainproof, sunshade and ventilated, and place the branches of the tung tree inside the support structure as nest tubes 7. Multiple stacked nest tubes 7 inside the support structure form nest tube bundles 8 for the reed wasps to build nests and reproduce.
[0042] Specifically, such as Figures 1 to 3 As shown, a fixing rod 1 is fixed to the ground. The length of the fixing rod 1 is 180cm. An inclined shielding cover 3 is built on the top surface of the fixing rod 1 using bolts 5, so that the bottom of the inclined shielding cover 3 forms a space to block wind and rain. The nest tube box 7 is installed on the fixing rod 1 through connectors, so that the nest tube box 7 is located below the inclined shielding cover 3, and the distance between the nest tube box 6 and the bottom surface is about 150cm. The nest tube box 6 is a straight cylindrical box with a cylindrical opening. The diameter of the nest tube box 6 is 25cm and the height is 40cm. The nest tube box 6 is placed horizontally so that the cylindrical opening of the nest tube box 6 is located on the side of the nest tube box 6 and the cylindrical opening of the nest tube box 6 is on the leeward and sunny side. Multiple sea buckthorns are tied into bundles with cable ties 9 or thin ropes and then filled into the cylindrical opening of the nest tube box 6 to form a nest tube bundle 8.
[0043] Among them, the surface of the fixing rod 1 is coated with an anti-ant coating 2 at a position 30cm from the bottom to prevent ants from entering the nest tube 7 and affecting the nest building of the bees.
[0044] Regarding the installation of the nest tube box 6: The connecting parts are two 70cm long horizontal bars 4 and several bolts 5. The two horizontal bars 4 pass through the side of the fixing rod 1 in parallel. The two horizontal bars 4 and the fixing rod 1 form two symmetrical support spaces. The two nest tube boxes 6 are respectively set in the two support spaces. The bolts 5 are threaded through the horizontal bars 4 and then threaded to the surface of the nest tube box 6 to fix the nest tube box 6.
[0045] Regarding the selection and preparation of nest tube 7 and nest tube bundle 8: Collect healthy, mold-free, and dried branches of *Symplocos cuspidata*. Cut all branches to a uniform length of 15cm-25cm, with a diameter of 3mm-8mm. When cutting, the cross-section of the branches should expose the white pith to attract bees. Then, prune the side branches and protrusions of the branches to ensure they are straight, facilitating subsequent health checks.
[0046] Regarding the high-temperature resistant design of the bee breeding device: the outer surface of the inclined shielding cover 3 is light-colored, such as white, which is conducive to reflecting sunlight and reducing internal heat absorption; at the same time, the nest tube box 6 is made of corrosion-resistant and high-temperature resistant engineering plastics, such as PP plastic, to improve the high-temperature resistance of the overall structure.
[0047] Regarding the orientation of the nest tube bundle 8: When placing the nest tube bundle 8, the smooth cut ends of the nest tubes 7 of the nest tube bundle 8 should face outwards from the opening of the box body to serve as the inlet and outlet for the bees, and to facilitate inspection and collection.
[0048] S20: Before or after the completion of the bee breeding facility, the process also includes: sowing or transplanting various nectar-producing plants 10 with alternating flowering periods within a radius of 50 to 100 meters outward from the bee breeding facility. The nectar-producing plants 10 are selected from species that bees prefer to visit and are highly adaptable to the island environment, in order to form a continuous flowering sequence and ensure that the bees have a sufficient source of pollen and nectar throughout the active season. The nectar-producing plants 10 can be one or more of the following: Scaevola taccada, Vitex rotundifolia, Macroptilium atropurpureum, Urena lobata, Phyla nodiflora, and Ruellia simplex.
[0049] S30: Screening of wasp development and parasitism by natural enemies: Check whether the nest tube 7 formed by the sea hibiscus has been sealed by wasps. Collect the sealed nest tubes 7, check the development of wasps in the nest tubes 7 and the parasitism by natural enemies. Select nest tubes 7 containing healthy wasps (also known as healthy nest tubes) for subsequent introduction to the island and for plant pollination.
[0050] Specifically, such as Figure 1 and 4 As shown, the inspection of the activity and parasitism of the reed wasps mainly adopts an invasive inspection method: regularly observe whether there is reed wasp activity at the opening of the nest tube 7, and whether there is sealing material (such as soil or plant debris). If the opening of the nest tube 7 is sealed, it means that the reed wasps have completed nest building; if the white pith at the opening of the nest tube 7 has been drilled with a round hole, it means that the reed wasps have built a nest inside the nest tube 7.
[0051] Regarding the timing of collection: At the end of the bee breeding season or when more than 80% of the brood tubes 7 in the brood tube bundle 8 have been sealed, the entire brood tube bundle 8 should be removed, and the sealed brood tubes 7 should be collected. During collection, each sealed brood tube 7 should be numbered and marked with the corresponding date and location. The sealed brood tubes 7 should be stored in a dark, well-ventilated environment at a temperature of 20℃-25℃, awaiting colony development.
[0052] Regarding the inspection of parasitism within the nest tube 7: A portable X-ray microscopic imaging instrument 11 was used to perform non-destructive testing on the nest tube 7. The imaging clearly distinguished the bodies of healthy parasitic wasp larvae 13, parasitic wasp pupae 12, and / or parasitic wasps 14 (such as broad-shouldered wasps, ichneumon wasps, and blue wasps), as well as some pollen masses 15. By comparing body size and density, the presence of parasitic wasps 14 could be accurately determined, thereby obtaining the health status of the parasitic wasps within the nest tube 7. The parasitized nest tubes 7 were then removed and destroyed, leaving only the nest tubes 7 containing healthy parasitic wasps for subsequent propagation and release. This non-invasive inspection method is key to achieving high-quality, large-scale propagation. This method not only preserves the integrity of the branches of the *Scabiosa spp.*, but also provides convenience for subsequent transportation to a certain extent, making the structure of the transport box 16 relatively simple.
[0053] S40: Transport and release of wasps: Transport the nest tube 7 containing healthy wasp bodies to the target island, and place it on a new wasp breeding device on the target island to release the wasps.
[0054] Specifically, such as Figure 1 and Figure 5As shown, the nest tube 7 containing healthy wasps is placed in a transport box 16 and transported to the target island. To improve the survival rate of the wasps in the nest tube 7 during high-temperature and long-distance transportation, the transport box 16 can be placed in a livestock incubator to maintain the temperature within the range of 18℃-22℃. The main body of the transport box 16 is a 35cm*20cm*10cm cuboid box. The opening of the transport box 16 is located on the side, and a transparent lid 17 is installed at the opening via a hinge or latch. The transparent lid 17 is detachably connected to the transport box 16 via a locking buckle 19 or a magnetic snap, enabling the opening and closing of the transparent lid 17 and facilitating the placement of the nest tube 7 while reducing the risk of it falling out. Both the inner wall of the transport box 16 and the transparent lid 17 are provided with ventilation holes 18 with a diameter of 1mm-5mm to allow air circulation within the transport box 16, facilitating the normal reproduction of the wasps inside the nest tube 7. The surface of the transport box 16 is made of a supportive plastic material, which reduces the risk of damage during transportation. The inner bottom surface of the transport box 16 is provided with a foam board 20 for cushioning and shock absorption. The foam board 20 is used to place the nest tube 7 containing healthy wasps. The foam board 20 can also be stacked between adjacent layers of nest tube 7 to improve the cushioning and shock absorption effect during transportation, and at the same time, it can also provide a certain degree of heat insulation when released in the wild.
[0055] When placing the nest tube 7 containing healthy wasps into the transport box 16: place the nest tube 7 with the nesting hole facing outwards into the transport box 16, fill the transport box 16 completely, and then close the transparent box cover 17. Before releasing the wasps, the emergence status of the nest tube 7 can be observed through the transparent box cover 17, and the release time can be arranged according to the actual situation. When using the transport box 16 as a release device, select an area near the nectar source plants 10 at the destination to place the transport box 16. The specific placement method is to keep the nest tube 7 inside in a nearly horizontal position, wrap the transport box 16 with rope or tape around a nearby thick tree branch, and open the transparent box cover 17 upwards for rain and sun protection.
[0056] Meanwhile, regarding the release of the wasps: the nest tube 7 containing healthy wasp bodies is transported to the target island using the transport box 16. The transportation time is usually chosen before the peak flowering period of island plants such as Pittosporum tobira on the target island. Then, the same wasp breeding device is built on the target island using the above-mentioned method for building the wasp breeding device. The nest tube 7 containing healthy wasp bodies in the transport box 16 is then transferred to the wasp breeding device to release the wasps. Alternatively, the transparent box cover 17 of the transport box 16 is opened, and the transport box 16 is fixed to a shady place such as a thick tree branch near the target plant community with rope or tape, and the box opening is kept slightly tilted downwards to achieve the effect of rain protection, so as to release the wasps.
[0057] After the nest tube 7 containing healthy reed wasps is placed, the emergence of wasps from the nest tube 7 containing healthy reed wasps is observed regularly, as is the reed wasps' visits to flowers. The pollination effect is evaluated by comparing the fruit set rate of each island plant before and after release.
[0058] In summary, the present invention provides a method for the propagation of *Pterocarya stenoptera* branches and their pollination of island plants. By constructing a *Pterocarya stenoptera* breeding device, branches preferred by the *Pterocarya stenoptera* branches, after specific pruning and modification, can be placed within the device. These branches serve as nest tubes (7) for the *Pterocarya stenoptera*, attracting the wasps and increasing their nesting success rate. The breeding device also provides wind, rain, and sun protection, adapting well to the island environment and effectively ensuring the stability of the internal microenvironment of the nest tubes (7), thus improving survival rates. Furthermore, a non-invasive inspection method can be used to examine the nest tubes (7), allowing for the removal of those parasitized by the parasitized wasps (14), thereby ensuring the health and quality of the released wasp colony. The wasps are then transported to the target island for release. This results in a low-cost, easy-to-operate, highly efficient, and stable solution specifically designed for island environments. This method significantly improves the acceptance rate and reproductive success rate of the *Pterocarya stenoptera*, and contributes to promoting local plant pollination and ecological restoration.
[0059] The embodiments of the present invention are not limited thereto. Based on the above description of the present invention, and using common technical knowledge and conventional means in the field, the present invention can be modified, replaced or combined in various other forms without departing from the basic technical idea of the present invention, and all such modifications, replacements or combinations fall within the scope of protection of the present invention.
