Abstract
Description
Technical Field
[0001] This invention belongs to the field of biotechnology and relates to a plant-derived attractant for peach tree pests and its application. Background Technology
[0002] Peach borer ( Conogethes punctiferalis (Lepidoptera: Pyralidae) is a highly polyphagous pest. Its larvae damage various fruit trees, spice crops, and vegetables. After hatching, the larvae bore into the stems of host plants, initially feeding between the stem and fruit, and later boring into the fruit, rendering it inedible. Therefore, it is a significant fruit-boring pest. This insect poses a serious economic threat to global agriculture and forestry, and climate change is exacerbating its population outbreaks. The larvae's feeding and excretion of sugary substances induce secondary pests, causing quality degradation and export restrictions. Cross-border transmission mainly occurs through branches, fruits, and seeds, and it has been listed as a quarantine pest by many countries.
[0003] Currently, the main control methods for peach fruit borer are chemical control. However, the frequent use of chemical pesticides has led to the peach fruit borer developing resistance to some pesticides. At the same time, pesticide residues threaten human health and have adverse effects on the environment. Therefore, there is an urgent need for new, green and efficient control methods.
[0004] Controlling insect populations by releasing compounds to alter their behavior is a more environmentally friendly method of pest management. Currently, sex pheromones from lepidopteran insects are primarily used as traps and mating agents. However, these pheromones only attract males in lepidopteran insects and have no effect on the behavior of females. Furthermore, most insects engage in multiple mating cycles, so simply controlling the number of males is not an effective way to control pests.
[0005] In addition, in field applications, these traps also have problems such as a high rate of attracting other moths and a lag in monitoring and early warning. Therefore, there is an urgent need for a highly efficient trap that is only effective against the peach borer. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a plant-derived attractant for peach tree pests and its application.
[0007] The objective of this invention can be achieved through the following technical solutions: One of the technical solutions of the present invention is to provide a plant-derived attractant for peach tree pests, selected from any one or more of β-phellandrene, 3-methylene-6-(tert-amyl)cyclohex-1-ene, 1-isopropyl-4-methylenecyclohexane, ethyl 4-methylenecyclohexane-1-carboxylate, 4-oxoisophorone, and 3-carene.
[0008] The second technical solution of the present invention is the application of a plant-derived attractant for peach tree pests as described in one of the above technical solutions, wherein the plant-derived attractant for peach tree pests is used to prepare a preparation for attracting peach tree pests outdoors.
[0009] In some specific embodiments, the peach tree pest is the peach borer.
[0010] In some specific embodiments, the formulation may be in the form of a liquid or a powder.
[0011] In some specific embodiments, when the peach tree pest plant-derived attractant is prepared as a liquid agent, the solvent of the liquid agent is n-hexane, and the concentration used is 1 μg / μL~100 μg / μL.
[0012] In some specific embodiments, when the peach tree pest plant-derived attractant is made into a powder for use, the mass of the powder used is 0.1~10 mg.
[0013] In some specific embodiments, the formulation is loaded into a capillary and used in combination with a trap during application.
[0014] In some specific embodiments, the trap is suspended from a peach tree at a height of 1 m above the ground during application.
[0015] In some specific embodiments, the traps are spaced 20 m apart during application.
[0016] In some specific embodiments, the trap is a boat-shaped trap when in use.
[0017] Compared with the prior art, the present invention has the following advantages: The plant-derived attractant for peach tree pests provided by this invention can attract and kill female adult pests in external environments such as fields, achieving zero trapping rate for miscellaneous moths and timely monitoring, thus greatly improving the control effect. Detailed Implementation
[0018] The present invention will now be described in detail with reference to specific embodiments. These embodiments are based on the technical solution of the present invention and provide detailed implementation methods and specific operating procedures. However, the scope of protection of the present invention is not limited to the following embodiments.
[0019] Example 1: This embodiment provides a method for preparing a liquid agent from plant-derived attractants for peach tree pests and its application. The preparation method includes the following steps: (1) Dilution: Using hexane as solvent, β-phellandrene, 3-methylene-6-(tert-pentyl)cyclohex-1-ene, 1-isopropyl-4-methylenecyclohexane, ethyl 4-methylenecyclohexane-1-carboxylate, 4-oxoisophorone, and 3-carene were diluted to 1 μg / μL, 10 μg / μL, and 100 μg / μL of mother liquor, shaken to mix well, and placed in a -20℃ refrigerator for later use.
[0020] (2) Loading: Using a plastic capillary tube as a carrier, fill 100 μL of the compound in step (1) to obtain the plant-derived attractant for peach orchard pests to be tested.
[0021] (3) Combination: Combine the white sticky board with the boat-shaped trap, put the peach orchard pest plant-derived attractant from step (2) on the trap, and place it in the peach orchard.
[0022] Example 2: This embodiment is the first verification of the performance of the various orchard pest plant-derived attractants in Example 1. From June 9 to June 29, 2025, three experimental plots were selected in the peach orchard of the Huangtao Picking and Fishing Center (30°09′N, 121°05′E) in Fengxian District, Shanghai, China, to conduct a lure verification experiment. Individual lures (plant-derived attractants for peach orchard pests) were tied to the top of boat-shaped traps (Beijing Zhongjie Sifang Biotechnology Co., Ltd., Beijing, China). The traps were suspended 1 m above the ground on peach trees, with each trap spaced 20 m apart. A randomized complete block design was used, with six replicates. The number of adult insects captured by each trap was recorded. Lures filled with hexane served as a control.
[0023] A total of 106 female peach fruit borers were captured in this experiment (see Table 1). The concentrations of 10 mg β-phellandrene, 0.1 mg ethyl 4-methylenecyclohexane-1-carboxylate, 0.1, 1, and 10 mg 4-oxoisophorone, and 0.1 mg 3-carene were significantly higher than the control (0 borers captured with n-hexane) (P < 0.01). An increase in the number of female adults attracted led to a decrease in mating rate, thereby reducing the reproductive rate and ultimately reducing the damage in the field.
[0024] Table 1 Example 3: This embodiment is to further verify the performance of the various orchard pest plant-derived attractants in Example 1. From June 29 to July 25, 2025, three experimental plots were selected in the peach orchard of the Huangtao Picking and Fishing Center in Fengxian District, Shanghai, China (30°09′N, 121°05′E) for a lure validation experiment. Individual lures (plant-derived attractants for peach orchard pests) were tied to the top of boat-shaped traps (Beijing Zhongjie Sifang Biotechnology Co., Ltd., Beijing, China). The traps were suspended 1 m above the ground on peach trees, with each trap spaced 20 m apart. A randomized complete block design was used, with six replicates. The number of adult insects captured by each trap was recorded. Lures filled with hexane served as a control.
[0025] A total of 154 female peach fruit borer adults were captured in this experiment (see Table 2). The amounts of 1 and 10 mg of β-phellandrene, 0.1 mg of 3-methylene-6-(tert-amyl)cyclohex-1-ene, 0.1 mg of 1-isopropyl-4-methylenecyclohexane, 0.1 mg of ethyl 4-methylenecyclohexane-1-carboxylate, 1 and 10 mg of 4-oxoisophorone, and 0.1, 1, and 10 mg of 3-carene were significantly higher than the control (0 adults captured with n-hexane) (P < 0.01). An increase in the number of female adults attracted led to a decrease in mating rate, thereby reducing the reproductive rate and ultimately reducing the degree of damage in the field.
