Technical Field
The invention belongs to the field of attractants, and particularly relates to an attractant composition for preventing and controlling spodoptera frugiperda and application thereof.
Background
Spodoptera frugiperda has the characteristics of strong reproductive capacity, wide hosts, fast migration and high destructiveness, and the Spodoptera frugiperda adults have strong long-distance migration capacity and can fly about 100 kilometers per night. The uncertainty of the occurrence area is large under the influence of the population quantity of the adults and the wind direction and the wind speed. At present, the insect is found in Yunnan, Guangxi, Guizhou and other places in China. Because the control of spodoptera frugiperda is mainly carried out by a chemical method, the spodoptera frugiperda causes different degrees of drug resistance to various insecticides and obviously influences the ecological environment, the search for a pollution-free sustainable control method is urgent, and the control of spodoptera frugiperda by using an attractant is one of effective measures.
Patent application (CN201911284177) of Guangdong province biological resource application research institute discloses a regional spodoptera frugiperda attractant for Guangdong regions, which consists of spodoptera frugiperda sex pheromones and plant volatile matters, wherein the mass ratio of the spodoptera frugiperda sex pheromones to the plant volatile matters is 1: 800-1000. the Spodoptera frugiperda sex pheromone consists of cis-9-tetradecyl acetate and cis-7-dodecenyl acetate, and the plant volatile matter consists of phenylacetaldehyde and linalool. Can be widely used for prediction and forecast of invasion of important pests, namely spodoptera frugiperda and pest safety prevention and control.
Patent application (CN202010655572) of Invitrogen agriculture science and technology Limited in Zhangzhou city discloses a spodoptera frugiperda imago attractant which consists of a sex attractant and a plant volatile odor compound; the sex attractant consists of cis-9-tetradecyl acetate and cis-7-dodecyl acetate; the plant volatile odor compound is one or more of ethyl benzoate, benzyl alcohol, methyl salicylate, benzaldehyde, phenylacetaldehyde, limonene, linalool and benzyl acetate.
Patent application (CN202010051273) of institute of plant protection and agricultural product quality safety of agricultural science of Anhui province discloses application of linalool oxide in attracting Spodoptera frugiperda; also discloses an attractant composition, which comprises linalool oxide, a light stabilizer, an antioxidant and a solvent
The applicant found through previous research (CN201910399034) that the luring activity of (Z) -7-dodecen-1-ol acetate, (Z) -9-tetradecene acetate, (Z) -11-hexadecenol acetate and (Z) -9-dodecen-1-ol acetate on Spodoptera frugiperda is remarkably improved after the combination use, and particularly when the mass ratio of (Z) -7-dodecen-1-ol acetate, (Z) -9-tetradecene acetate, (Z) -11-hexadecenol acetate and (Z) -9-dodecen-1-ol acetate is 0.02:2.5:0.5:0.02, the luring effect is up to 21.10 heads/day, and the components have better luring activity.
Based on the previous research, the applicant further developed spodoptera frugiperda attractant compositions having excellent attracting effects.

Detailed Description
The following detailed description of specific embodiments of the present invention is provided in conjunction with examples, but it should be understood that the scope of the present invention is not limited to the specific embodiments.
Example 1: experiment for attracting and monitoring effects of spodoptera frugiperda by different attractant formulas
Test site: the corn planting method comprises the following steps of planting corn in Guangxi guest in a core area, and planting the corn in a piece-by-piece mode in the area.
The test method comprises the following steps: preparing lure cores according to the formula shown in the table 1, placing the lure cores in a ship-shaped trap, enabling the trap interval to be about 10 meters, enabling the height of the trap cores to be 1.5 meters from the ground, adopting a random block design, repeating the treatment for three times every time, continuously surveying for 15 days, counting the lure quantity of each trap in the morning every day, removing Spodoptera frugiperda trapped by the trap, and recording the total trapping quantity.
Table 1 attractant formulations
The results of the tests were analyzed and are shown in Table 1 and FIG. 1.
As can be seen from Table 1 and FIG. 1, the effect of trapping Spodoptera frugiperda by sex pheromone and odor substance can be improved; the trapping effects are ranked from large to small: formula 4 > formula 2 > formula 5 > formula 1 > formula 8 > formula 3 > formula 7 > formula 6 > formula 9 >; however, when the sex pheromone is combined with the odor substance, the trapping effect is better when the odor substance is not more in variety, and the trapping effect can be obviously improved only when the sex pheromone is combined with the appropriate odor substance.
As can be seen from the comparison between the formula 4 and the formula 6, the linalool oxide and the methyl salicylate have a remarkable effect of enhancing the luring effect, and the total trapping amount is 370.
Example 2:experiment for attracting and monitoring effects of spodoptera frugiperda by different attractant formulas
The specific test method is referred to in example 1.
Table 2 attractant formulations
And (3) analyzing test results: see figure 2 for details.
As can be seen from fig. 2, the different proportions of linalool oxide and methyl salicylate have a significant effect on the attraction: when the proportion of linalool oxide and methyl salicylate in the formula 11 is 1:4, the attraction effect is poor, and the total trapping amount is 285 heads; the luring effect of the formulas 12, 13 and 14 is better, especially when the ratio of linalool oxide to methyl salicylate is 4:1, the luring effect is the best, and the total luring amount is 331 heads.
The above description is not meant to be limiting, it being noted that: it will be apparent to those skilled in the art that various changes, modifications, additions and substitutions can be made without departing from the true scope of the invention, and these improvements and modifications should also be construed as within the scope of the invention.
