[0002] With the development of urbanization and industrialization, human activities intersect with natural ecological environments more and more frequently, and birds and some small animals use low-altitude areas, which causes many conflicts with human activities. In particular, in places such as power facilities, airports, farms, and residential areas, the presence of birds and animals not only may cause disturbances to human activities, but also may pose potential threats to the facilities themselves. For example, in power systems, the nesting behavior of birds may cause short circuits or other failures, affecting the stability and safety of power supply.

[0003] Traditional bird repelling methods, such as physical isolation, sound repelling, and chemical agents, have certain limitations. Physical isolation may affect the operating efficiency of the facilities, sound repelling may cause noise pollution to the surrounding environment, and the use of chemical agents may pose risks to the ecological environment and human health. Therefore, it is of great significance to develop a safe, environmentally friendly, and efficient bird repelling agent to solve the above problems.

[0004] Chinese granted patent CN101361495B discloses a bird repelling composition including the following components in total weight percentage: a bird repelling fragrance selected from one or both of methyl anthranilate 1% to 50%, Houttuynia cordata essential oil 0.1% to 5%, or musk T 10% to 21%; an antioxidant selected from one or both of 2,6-di-tert-butyl-p-cresol or sodium ascorbate, 0.02% to 0.5%, and the rest is a slow-release carrier. A bird repelling colloidal mixture is prepared from the bird repelling composition, and the slow-release carrier includes organic or inorganic bases, unsaturated fatty acids, preservatives, emulsifiers, stabilizers, and anti-freezing agents. A bird repelling colloidal suspension is prepared from the bird repelling composition, and the slow-release carrier includes sodium octenyl succinate starch or β-cyclodextrin, and also includes preservatives, emulsifiers, stabilizers, and anti-freezing agents. The invention uses a dilution spraying method to use the smell of the bird repelling fragrance to cause an allergic reaction of the trigeminal nerve of birds and an aversion reaction after pecking, is convenient to use, has good repelling effect, is harmless to birds and plants, and is an environmentally friendly biological agent product. However, the bird repelling composition prepared by the invention has unsatisfactory bird repelling effect and poor long-term efficacy. SUMMARY

[0087] Test Example 1

[0088] Bird Repellent Effect Test

[0089] To evaluate the effectiveness of the repellent agent developed by the present application, the following test procedure was conducted to ensure effective management of bird damage problems on 15KV transmission lines. The test involved repellent agent samples including Examples 1-6 and Comparative Examples 1-2, which were applied to specific power facilities.

[0090] The specific steps of the test procedure are as follows:

[0091] 1. The selected test area is a 15KV voltage level transmission line, each area is 1 kilometer long, and contains 20 power towers. Each tower has one single cross arm and two double cross arms as the main area for birds to rest.

[0092] 2. A specially designed mortar knife is fixed to the front end of a long stick to facilitate the operator to evenly apply the repellent agent to the outer surface of the cross arm. Ensure that the repellent agent is applied to a thickness of 3 mm and covers the entire outer surface of the cross arm to form an effective bird repellent layer.

[0093] 3. Count the number of birds that fall on the test area lines and their accessories, with the counting standard being only the landing of birds, without limiting the time they stay. Before applying the bird repellent, the number of birds that fall in the corresponding area has been recorded for 30 consecutive days as control data for the test. The observation period for each test area is set to 30 days per cycle, and two consecutive cycles are observed to ensure the reliability of the data and the durability of the bird repellent effect.

[0094] After the test is completed, the data is collected and analyzed, and the number of birds that fall before and after the bird repellent is applied is compared to evaluate the effect of the bird repellent.

[0095] The test results are shown in Table 1.

[0096] Table 1

[0097]

[0098] Test Example 2

[0099] The stability of the repellent was evaluated by calculating the decline rate of the bird repellency percentage according to the bird repellency percentage in Test Example 1, to determine the long-term effectiveness of the developed repellent.

[0100] Decline rate = (bird repellency of the first period - bird repellency of the second period) / bird repellency of the first period x 100%

[0101] The test results are shown in Table 2.

[0102] Table 2

[0103]

[0104]

[0105] As can be seen from the data in Table 1 and Table 2, the repellent prepared in Example 1 has good bird repellency, and the bird repellency effect declines at a low rate during long-term use, and has good long-term effectiveness.

[0106] The enhancer added in Example 1. The enhancer enhances the biological activity and environmental stability of the bird repellent through its unique chemical composition and preparation process. The components such as DL-α-phosphatidylcholine, cholesterol, Tween 80 and butylated hydroxyanisole in the enhancer not only improve the permeability and adhesion of the repellent, making it easier to contact the visual organs of birds, but also enhance the antioxidant capacity of the repellent, reducing the negative impact of environmental factors on the effectiveness of the repellent. In addition, the introduction of the enhancer may also improve the uniform distribution of the repellent on the tower surface and enhance its durability, thereby maintaining a high bird repellency effect during long-term use. In contrast, the absence of these key components in Comparative Example 2 results in a lower bird repellency effect and stability than Example 1.

[0107] The DL-α-phosphatidylcholine used in Example 1, as a key ingredient, can have an impact on the visual and nervous systems of birds due to its unique molecular structure and biological activity, thus providing better bird repellent effects. DL-α-phosphatidylcholine is an important phospholipid widely present in biological cell membranes, which has the function of promoting cell membrane fluidity and function. In bird repellent agents, it can enhance the penetration of other active ingredients, helping these ingredients to more effectively contact the sensory organs of birds, especially the eyes. In addition, the antioxidant activity of DL-α-phosphatidylcholine can help improve the stability and durability of the agent, making it less susceptible to decomposition in the natural environment, thus maintaining long-term effectiveness. The amphiphilic nature of this phospholipid (both hydrophilic and lipophilic) can help the uniform distribution and adhesion of the agent components on the tower surface, reducing the loss of the agent due to environmental factors such as wind and rain. In contrast, phosphatidylserine in Example 2 and soybean phospholipid in Example 3, although they also have certain biological activity, may not be as good as DL-α-phosphatidylcholine in terms of penetration, stability, or synergistic effects with other ingredients in the agent. This may be one of the reasons why Example 1 has a higher bird repellent rate and a lower rate of effectiveness decline.

[0108] The resorcinol diglycidyl ether used in Example 1 as an active ingredient, with its unique chemical structure containing two epoxy groups, can provide enhanced effectiveness and stability to the bird repellent agent. This structure can give the agent better penetration, helping the agent components penetrate deep into the visual organs of birds, affecting their visual perception, thus producing a strong repellent effect. At the same time, it can also enhance the antioxidant activity of the agent, improving its stability and durability in the natural environment. In contrast, glycidyl methacrylate in Example 4, butylene oxide in Example 5, and ethylene oxide in Example 6, although they also contain epoxy groups, their molecular structures and physicochemical properties may differ from those of resorcinol diglycidyl ether, which can affect their performance in terms of penetration, synergistic effects with other ingredients in the agent, and stability. For example, glycidyl methacrylate may not be as good as resorcinol diglycidyl ether in terms of penetration; butylene oxide and ethylene oxide, although they also provide epoxy groups, may have limitations in terms of interaction with other agent components or environmental adaptability. In addition, the introduction of resorcinol diglycidyl ether can also promote the interaction of agent components with the visual organs of birds, enhancing the repellent effect of the agent. This enhanced effect may be related to the polarity, molecular size, and shape of resorcinol diglycidyl ether, which together improve the agent's impact on bird behavior.

[0109] The superior performance of the repellent agent in Example 1 can also be attributed to the addition of cholesterol, Tween 80 and butylated hydroxyanisole in the formulation of the enhancer. Cholesterol can enhance the interaction and penetration of the agent with the avian sensory organs, Tween 80 as a surfactant reduces the surface tension, improves the spreading and adhesion of the agent, while the antioxidant effect of butylated hydroxyanisole helps to protect the components of the agent and prolong its effective action time. The synergistic effect of these components can improve the biological activity and environmental adaptability of the agent, thus showing significant advantages in bird repellent effect and stability compared to the comparative example 1 without the addition of these components.
