Description

Technical Field

[0001] The present application relates to the field of insect trapping, and in particular to a synergistic trapping system for tomato leafminers using ultraviolet light and sex pheromones, and its application. Background Art

[0002] The tomato leafminer, Tuta absoluta (Meyrick), belongs to the genus Tuta in the family Meyrickidae of the order Lepidoptera. It is a major invasive agricultural pest that spreads rapidly. Its larvae are known for their boring habits and are highly secretive. Furthermore, the tiny size of newly hatched larvae makes it difficult to accurately determine the optimal time to control them, often resulting in suboptimal control efforts.

[0003] Sex pheromone-based trapping technology has been widely used in monitoring and early warning of tomato leafminer pests. Its advantages include ease of use, strong specificity, and minimal damage to natural enemies. Currently, it is the most commonly used method for monitoring tomato leafminer population dynamics and forecasting the occurrence period and abundance of tomato leafminer pests. However, because sex pheromone trapping primarily attracts male insects, its control effectiveness is less than ideal, making it difficult to use for large-scale trapping and control of the pest.

[0004] Light trapping, based on insect phototaxis, can be used to monitor pest population dynamics and kill large numbers of them. Not only does it prevent pests from developing resistance, it's also environmentally friendly and low-cost. However, female moths typically have a lower rate of attracting light than male moths, resulting in less than satisfactory control. While there have been reports on the effectiveness of light traps for tomato leafminers, the results have been mixed.

[0005] In order to further improve the monitoring and control effect of tomato leafminer by trapping, this study developed a synergistic trapping system of ultraviolet light and sex pheromones with better trapping effect and more promising application prospects for prevention and control, which is used to efficiently trap and kill male and female moths. The research results are of great significance to the efficient use of physical and chemical trapping technology, and the precise monitoring and green control of tomato leafminer. Summary of the Invention

[0006] The purpose of the present invention is to provide a synergistic trapping system for tomato leafminers using ultraviolet light and sex pheromones.

[0007] Another object of the present invention is to provide an application of the above-mentioned tomato leafminer ultraviolet light and sex pheromone synergistic trapping system.

[0008] According to the present invention, the method for synergistically increasing the amount of moths attracted to male and female tomato leafminers, the moth-attracting efficiency, and the amount of egg-bearing females trapped comprises the following steps:

[0009] Under facility cultivation conditions, ultraviolet lamps and tomato leafminer sex attractants are placed directly on the ground.

[0010] According to the method of the present invention, the amount of moths attracted to male and female tomato leafminers, the moth-attracting efficiency and the amount of egg-bearing females captured are synergistically increased, wherein the effective component of the tomato leafminer sex attractant core is trans-3, cis-8, cis-11-tetradecatriene acetate.

[0011] The tomato leafminer ultraviolet light and sex pheromone synergistic trapping system according to the present invention comprises an ultraviolet lamp and a tomato leafminer sex attractant core.

[0012] The experimental results show that under facility cultivation conditions, when three different types of traps, including sex traps, ultraviolet light traps, and synergistic trapping systems, are placed directly on the ground, male and female tomato leafminers have the strongest tendency to the synergistic trapping system of this application, and the average daily total number of male and female moths trapped, the number of moths trapped for males, and the number of moths trapped for females and egg-bearing females are all the highest; and within the 108-day trapping period, the moth-trapping efficiency of the synergistic trapping system of this application is always advantageous, significantly improving the trapping efficiency while taking into account ecological safety.

[0013] The ultraviolet light trap and the synergistic trapping system of the present application were placed directly on the ground, which not only attracted a high proportion of female adults (the female insect ratio was 57.7% to 59.59%), but also attracted a high proportion of egg-bearing female insects (84.19% and 85.21%), and the synergistic trapping system of the present application had a better trapping effect.

[0014] The synergistic trapping system of the present application has a high moth-attracting capacity and a high proportion of egg-bearing female insects in the trapping and killing effect, which plays an important role in reducing the amount of eggs laid in the field, suppressing the insect population and alleviating damage, as well as scientifically evaluating the control effects of physical and chemical trapping technology. It is suitable for the construction and application promotion of organic agriculture and IPM (integrated pest management) systems.

[0015] The synergistic trapping system trial was conducted under greenhouse conditions, and only a small number of natural enemy insects were attracted. Currently, protected tomato production mostly uses bear beetles for pollination to increase fruit set. By using fragrance-free detergents, the trapping of insect-borne insects can be completely avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The experiments in the following examples were conducted in a rain shelter (also with the function of sheltering from rain and keeping warm, collectively referred to as a greenhouse) at an organic fruit and vegetable production base in Hongta District, Yuxi City, Yunnan Province (24°20′N, 102°32′E). The greenhouse is a multi-span greenhouse with a plastic film (+insect-proof net) structure, with a height of 6m and an area of ​​approximately 3 mu. The planting method of the experimental greenhouse is nutrient soil potting, with a drip irrigation system for water and fertilizer supply, a spacing of about 50cm between plants and rows, and a spacing of about 100cm between ridges. 2-3 crops are planted in a year, with continuous cropping, and all nutrient soil is renewed. Tomato varieties / crops are adjusted according to the overall planning of the base. Different greenhouses are planted year-round (in batches of 2 to 3 months) to ensure a continuous year-round supply of tomato fruits. No chemical agents or chemical fertilizers are used during the growth period of tomatoes. Cultivation and management implement the requirements of the national organic product production and management system. During this period, old leaves at the bottom and leaves with pests and diseases are removed in a timely manner. Tomato fruits are mainly picked as fresh fruits after they mature.

[0026] Test Period: The moth-attracting effectiveness of different trap types was evaluated on spring and summer tomato plants, which grow from April to August. This period also coincides with a high population of tomato leafminers, making it beneficial for evaluating trapping effectiveness. The field evaluation trial lasted 108 days, from planting to pulling out the tomato seedlings.

[0027] Test materials:

[0028] like Figure 9 As shown, the tomato leafminer ultraviolet light and sex pheromone synergistic trapping system includes a die-cast aluminum small T-joint 1, a waterproof sunscreen hood 2, a spiral lamp socket 3, an ultraviolet LED lamp tube 4, a sex attractant core 5, a sex attractant core fixing device 6, and a flooded insect collecting tray 7.

[0029] The sex attractant 5 is a bell-shaped natural silicone rubber plug (rubber-headed sex attractant) containing a single component (trans-3, cis-8, cis-11-tetradecatrienyl acetate (3E,8Z,11Z)-3,8,11-tetradecatrienyl acetate) with an active ingredient content of 800 μg per plug. According to the product instructions, the sex attractant should be replaced every 30 days.

[0030] The ultraviolet LED lamp has a wavelength of 390nm, a power of 12W, a rated voltage of 220V, is powered by an AC power supply, and has a universal E27 screw port.

[0031] The waterproof sunscreen 2 consists of a white metal cover and a die-cast aluminum waterproof three-way lamp holder. The metal cover is made of painted iron sheet, dome-shaped, 8 cm high and 30 cm in outer diameter. A circular hole (4.5 cm in diameter) is located in the center of the top of the metal cover to secure the die-cast aluminum three-way lamp holder. The three-way connection at the top of the lamp holder secures the power cord, while the bottom of the lamp holder secures the lamp tube. A metal circular ring (1.2 cm in inner diameter) is located in the center of the three-way connection to secure the metal cover.

[0032] Height-adjustable sex attractant fixture: Cut a length of approximately 41cm of thin lead wire (1.2mm diameter) and twist it with needle-nose pliers in the middle of the wire to form a loop approximately 0.5cm in diameter. Cut a length of approximately 10cm of tie wire and thread one end of the tie wire through the loop to secure it to the thin lead wire. Then, bend both ends of the wire inward to form a small hook (approximately 1.5cm long). When in use, secure the thin lead wire with the tie wire across the middle of the upper end of the insect collection tray.

[0033] The flooded insect trap is made of polypropylene, has an inner diameter of 35.0 cm, an outer diameter of 38 cm, and a height / depth of 4 cm. The trap is filled with tap water containing 0.2% detergent (preferably fragrance-free to minimize damage to natural enemies and insect-borne insects), with the water level approximately 1 cm from the upper edge of the trap.

[0034] Example 1

[0035] 1.1 Experimental setup

[0036] The experiment has three treatments. The details are as follows:

[0037] Treatment 1: Single sexual information trapping and luring, referred to as sexual trapping method, the overall device is called sexual trap;

[0038] Treatment 2: Single ultraviolet light trapping, referred to as ultraviolet light trapping, the overall device is called ultraviolet light trap;

[0039] Treatment 3: Synergistic trapping with ultraviolet light and sex pheromones, which is composed of a combination of ultraviolet lamps and sex attractant cores, is referred to as the synergistic trapping method with ultraviolet light and sex pheromones, and the overall device is called a synergistic trapping system.

[0040] Sex trap: The trap consists of a sex attractant designed for tomato leafminers, a height-adjustable sex attractant fixture, and a flooded insect collection tray. The flooded insect collection tray is filled with tap water containing 0.2% detergent (no fragrances), with the water level approximately 1 cm from the top edge of the tray. A thin lead wire with a tie is secured across the middle of the tray's top edge. The tie, suspended from the middle of the lead wire, is wrapped around the sex attractant, and the tie is used to adjust the distance between the sex attractant and the water surface, maintaining a constant 0.5 cm to 1 cm. The flooded insect collection tray with the sex attractant is placed directly on the ground. Replace the sex attractant every 30 days according to the product instructions.

[0041] Light trap: The light trap consists of an LED UV lamp (wavelength 390nm), a waterproof sunscreen, and a flooded insect collection tray. The tray is filled with tap water containing 0.2% detergent (no fragrances). The water level should be approximately 1 cm above the top edge of the tray, and the LED lamp should be 10-12 cm above the water level. The tray should be placed directly on the ground. Replace the LED UV lamp annually.

[0042] Synergistic trapping system: The synergistic trapping system of this embodiment consists of three parts: the top is the light source layer, the middle is the sex pheromone layer, and the bottom is the pest killing layer. The specific structure is as follows:

[0043] 1) Upper light source layer: consists of two parts: LED UV lamp tube (wavelength 390nm) and waterproof sunscreen lampshade (including white painted metal cover and die-cast aluminum small three-way waterproof lamp head).

[0044] 2) Middle pheromone layer: It consists of two parts: a sex attractant core specially designed for tomato leafminers and a height-adjustable sex attractant core fixing device.

[0045] 3) The lower pest killing layer consists of two parts: a flooded insect collecting tray and tap water containing 0.2% detergent (without any fragrance).

[0046] When using the device in the field, place the submerged insect trap directly on the ground, with the water level approximately 1 cm above the top edge of the trap. The LED light tube should be approximately 10 cm above the water surface, and the lure core should be 0.5 to 1 cm above the water surface. According to the product instructions, replace the lure core every 30 days and the LED UV lamp annually.

[0047] The experiment employed three treatments: sex pheromone trapping, ultraviolet light trapping, and a synergistic trapping system using ultraviolet light and sex pheromones. Four traps were replicated in each treatment. The three trap types were placed alternately in a checkerboard pattern within the same greenhouse, with a spacing of 15 to 18 meters between adjacent traps.

[0048] For the pheromone trapping method, the number of male (and female) insects in the water tray of each trap was observed and counted around 10:00 AM daily. For the UV light and synergistic trapping methods, the lights were turned on at sunset and off at sunrise daily. After the lights were turned off, the number of male and female insects in the water tray of each trap was observed and counted. After counting, the insects were removed from the flooded trays of each of the three trap types and disposed of collectively. Furthermore, the positions of the traps were rotated clockwise every two days, and appropriate amounts of tap water (containing 0.2% detergent) were added to the water trays of each of the three trap types each evening when the lights were turned on.

[0049] The daily moth catches for each sex trap, UV light trap, and synergistic trapping system were counted and averaged. Data were analyzed using Excel 2010 and SPSS 21.0 software, and the Kolmogorov-Smirnov test was used to determine if the data conformed to a normal distribution. Paired t-tests were used to test for significant differences in daily moth catches (including the number of males, females, egg-bearing females, and females and males) among the three different trap / trap systems. One-way ANOVA (LSD) tests were used to test for significant differences in the daily average total number of moths caught and the daily average proportion of male moths caught between the different trap / trap types (data were arcsine transformed). Independent t-tests were used to test for significant differences in the proportion of female / egg-bearing females between the UV light trap and the synergistic trapping system (data were arcsine transformed). The significance level (α) was set at 0.05.

[0050] 1.2 Results and Analysis

[0051] 1.2.1 Daily and average daily moth numbers of male and female moths attracted by different types of traps / trapping systems

[0052] Sex traps, ultraviolet light traps and synergistic trapping systems were used to trap and kill tomato leafminers during the main outbreak period of April to August (spring and summer tomato crops). The daily average total number of moths attracted by the three traps / trapping systems was subjected to paired data t-tests. The results showed that the daily total number of moths attracted by the synergistic trapping system was significantly higher than that of the ultraviolet light trap and sex trap ( Figure 9), and the order from high to low was synergistic trapping system > ultraviolet light trap > sex trap, and the differences were significant (synergistic trapping system vs. sex trap: t = 9.160, df = 107, P < 0.0001; synergistic trapping system vs. ultraviolet light trap: t = 5.496, df = 107, P < 0.0001) ( Figure 1 ).like Figure 1 The average daily number of moths caught is 26.25 for the sex trap (male moths only), 97.91 for the UV light trap, and 127.20 for the synergistic trapping system. Figure 2 As shown, the synergistic trapping system attracted 1.30 times and 4.85 times the moths of the UV light trap and the sex trap, respectively. The maximum daily moth catch was 582.00, which was 1.19 times and 2.59 times that of the UV light trap and the sex trap, respectively. This indicates that the synergistic trapping system has a higher ability to attract tomato leafminers than the UV light trap and the sex trap.

[0053] 1.2.2 Daily and average daily male moth captures by different types of traps / trapping systems

[0054] Sex traps, ultraviolet light traps and synergistic trapping systems were used to trap and kill tomato leafminers during the main outbreak period of April to August (spring and summer tomato crops). The daily average number of male moths trapped by the three traps / traps was subjected to a paired data t-test. The results showed that the daily number of male moths trapped by the synergistic trapping system was significantly higher than that of the ultraviolet light trap and sex trap ( Figure 3 ), and the order from high to low was synergistic trapping system > ultraviolet light trap > sex trap, and the differences were significant (synergistic trapping system vs. sex trap: t = 7.432, df = 107, P < 0.0001; synergistic trapping system vs. ultraviolet light trap: t = 3.675, df = 107, P < 0.0001) ( Figure 3 The average daily number of male moths trapped by the sex trap was 26.25, the ultraviolet light trap was 39.51, and the synergistic trapping system was 50.75. The average daily number of male moths trapped by the synergistic trapping system was 1.28 times and 1.93 times that of the ultraviolet light trap and the sex trap, respectively. Figure 4 ); The maximum daily number of male moths trapped by the synergistic trapping system was 299.00, which was 1.63 times and 1.33 times that of the UV light trap and sex trap, respectively ( Figure 3 ). This indicates that the synergistic trapping system has a stronger ability to attract male tomato leafminers than the ultraviolet light trap and the sex trap.

[0055] 1.2.3 Daily and average daily moth numbers attracted to female moths by different types of traps / trapping systems

[0056] In this study, the sex trap only attracted males, and females were rarely caught, so they were not counted. The UV light trap and the synergistic trapping system were used to trap and kill the tomato leafminer during the main outbreak period of April to August (spring and summer tomato crops). The daily average female moth catches of the two traps / traps were subjected to a paired data t-test. The results showed that the daily female moth catches of the synergistic trapping system were significantly higher than those of the UV light trap (t = 5.259, df = 107, P < 0.0001) ( Figure 5 ); The average daily number of female moths trapped by the UV light trap was 58.40, and the synergistic trapping system was 76.45. The average daily number of female moths trapped by the synergistic trapping system was 1.31 times that of the UV light trap ( Figure 6 The maximum daily number of female moths trapped by the synergistic trapping system was 448.0, which was 1.34 times that of the UV light trap ( Figure 5 ). This indicates that the synergistic trapping system has a higher ability to attract female tomato leafminers than the ultraviolet light trap.

[0057] 1.2.4 Daily and average daily moth yields of egg-bearing female moths by different types of traps / trapping systems

[0058] In this study, the sex trap only attracted males, with very few females, so they were not counted. The UV light trap and the synergistic trapping system were used to trap and kill the tomato leafminer during the main outbreak period of April to August (spring and summer tomato crops). A paired t-test was performed on the daily average number of egg-bearing female moths captured by the two traps / traps. The results showed that the daily number of egg-bearing female moths captured by the synergistic trapping system was significantly higher than that by the UV light trap (t = 5.293, df = 107, P < 0.0001) ( Figure 7 ); The average daily number of egg-bearing female moths trapped by the UV light trap was 49.31, and the synergistic trapping system was 66.26. The average daily number of egg-bearing female moths trapped by the synergistic trapping system was 1.34 times that of the UV light trap ( Figure 8 The synergistic trapping system has a maximum daily capture rate of 419.75 female moths with eggs, which is 1.38 times that of the ultraviolet light trap. Figure 7 ). This indicates that the synergistic trapping system has a higher ability to attract egg-bearing female moths of tomato leafminer than the ultraviolet light trap.

[0059] 1.2.5 Evaluation of moth-attracting efficiency of different types of traps / trapping systems

[0060] The moth-trapping efficiency of the three types of traps / traps was evaluated based on the total proportion of male and female moths trapped, the proportion of male moths trapped, the proportion of female moths trapped, and the proportion of female moths trapped with eggs. The results showed that the synergistic trapping system had the highest moth-trapping efficiency and the largest proportion. Among them, the total proportion of moths trapped for male and female moths increased by 35.93% and 6.99% compared with the sex trap and ultraviolet light trap, respectively, and the proportion of moths trapped for male moths increased by 18.09% and 7.59%, respectively; the proportion of moths trapped for female moths and female moths with eggs increased by 5.66% and 6.16%, respectively, compared with the ultraviolet light trap (Table 1). Furthermore, moth-trapping efficiency and effectiveness were evaluated using the average daily total number of moths captured, the female-to-female ratio, the percentage of females with eggs, and the number of natural enemies accidentally killed. The results showed that the synergistic trapping system achieved the highest average daily total number of moths captured, significantly exceeding those of the sex trap and the UV light trap, with increases of 79.36% and 23.03% compared to the sex trap and the UV light trap, respectively. The female-to-female ratio exceeded 57%, with a high percentage of females with eggs reaching 85% (Table 2). Although the synergistic trapping system attracted a small number of natural enemies, this was less than one hundred thousandth of the number captured for the target species, the tomato leafminer, and significantly lower than that captured by the UV light trap (Table 2). This demonstrates that the synergistic trapping system has a higher moth-trapping efficiency than the sex trap and the UV light trap, while minimizing the impact on natural enemies.

[0063]

[0064] Data in the table are mean ± standard error (SE), n = 4. Data within the same column with different lowercase letters indicate significant differences between different trap types at the 0.05 level (paired sample t-test). *: Percentage of moths caught / % ​​= (number of moths caught by any one trap type / total number of moths caught by all three trap types) × 100%; / : Sex traps rarely attracted females, so the percentages of females and egg-bearing females were not calculated.

[0065] Table 2 Evaluation of the effectiveness of different types of traps in attracting tomato leafminers

[0066]

[0067] Data in the table are mean ± standard error, n = 4. *: Percentage of female moths laden with eggs / % = (number of female moths laden with eggs / number of female moths) × 100%; / : The sex trap rarely attracted females, so the percentages of females and laden females were not calculated.

[0068] The results showed that under facility cultivation conditions, when three different types of traps, including sex traps, ultraviolet light traps, and synergistic trapping systems, were placed directly on the ground, male and female tomato leafminers had the strongest tendency towards the synergistic trapping system of this application, and the average daily total number of male and female moths trapped, the number of moths trapped for males, and the number of moths trapped for females and egg-bearing females were all the highest; and during the 108-day trapping period, the moth-trapping efficiency of the synergistic trapping system of this application was always advantageous, significantly improving the trapping efficiency while taking into account ecological safety.

[0069] The ultraviolet light trap and the synergistic trapping system of the present application were placed directly on the ground, which not only attracted a high proportion of female adults (the female insect ratio was 57.7% to 59.59%), but also attracted a high proportion of egg-bearing female insects (84.19% and 85.21%), and the synergistic trapping system of the present application had a better trapping effect.

[0070] The synergistic trapping system of the present application has a high moth-attracting capacity and a high proportion of egg-bearing female insects in the trapping and killing effect, which plays an important role in reducing the amount of eggs laid in the field, suppressing the insect population and alleviating damage, as well as scientifically evaluating the control effects of physical and chemical trapping technology. It is suitable for the construction and application promotion of organic agriculture and IPM (integrated pest management) systems.

[0071] The synergistic trapping system trial was conducted under greenhouse conditions, and only a small number of natural enemy insects were attracted. Currently, protected tomato production mostly uses bear beetles for pollination to increase fruit set. By using fragrance-free detergents, the trapping of insect-borne insects can be completely avoided.
