Problems solved by technology

Sekul and Sparks first reported that Z9-14:AC is a sex pheromone component of fall armyworm, which can attract male fall armyworm in the laboratory, but the attracting effect is poor in the field
Then they proposed that Z9-12: AC is also a sex pheromone component of fall armyworm. A single Z9-12: AC mixed with olive oil can attract male fall armyworm in the field, but Tumlinson et al. found that Z9-12: Only when the dosage of AC is 25mg / high-adsorption slow-release carrier can it trap Spodoptera frugiperda, far exceeding the usual dosage of sex pheromones

[0050] A sex lure for Spodoptera frugiperda, the ratio of its raw materials is shown in Table 1-3.

[0051] S1, cis-9-tetradecene acetate, cis-11-hexadecene acetate, cis-7-dodecene acetate, cis-9-dodecene acetate , mixed evenly to obtain compound pheromone;

[0052] S2, adding 3,4,5-trihydroxybenzoic acid n-propyl ester antioxidant, hindered amine light stabilizer 622 light stabilizer to compound sex pheromone, then adding synergist, corn germ extract, mixing evenly to obtain Main ingredient;

[0053] S3, uniformly mixing 60 mg of main ingredients and 30 mg of olive oil auxiliary materials to obtain a sex attractant.

[0054] Wherein, the synergist is prepared by the following method: uniformly mixing citric acid, malic acid, limonene, and green leaf volatiles to obtain the synergist.

[0055] Green leaf volatiles are prepared by the following method: cis-3-hexenal, cis-3-hexenal, trans-2-hexenal are mixed evenly to obtain green leaf volatiles, cis-3-hexenal, cis The weigh...

Embodiment 2-12

[0061] A sex lure for Spodoptera frugiperda, the preparation method of the sex lure in Example 2-12 is the same as that in Example 1, the difference between Example 2-12 and Example 1 is that the raw material ratio of the sex lure Different, its raw material ratio is shown in Table 1-3.

Embodiment 13

[0063] A sex lure for Spodoptera frugiperda. The difference between this embodiment and Embodiment 3 lies in the different preparation methods.

[0064] S1, cis-9-tetradecene acetate, cis-11-hexadecene acetate, cis-7-dodecene acetate, cis-9-dodecene acetate , mixed evenly to obtain compound pheromone;

[0065] S2. Add butyl hydroxyanisole antioxidant and light stabilizer ZX-70 light stabilizer to the compound pheromone, then add synergist, mix evenly, and obtain the main ingredient;

Abstract

The present invention relates to a sex lure of Spodoptera frugiperda and its preparation method and application. The raw materials of the sex lure of Spodoptera frugiperda include main materials and auxiliary materials, and the main materials include composite pheromones, synergists, antioxidants, light Stabilizers, complex sex pheromones including cis-9-tetradecyl acetate, cis-11-hexadecene acetate, cis-7-dodecene acetate, cis-9-dodecene Carbyl acetate; synergists include citric acid, malic acid, limonene, green leaf volatiles. The sex attractant, through the synergy between raw materials, not only improves the trapping effect of the sex attractant on fall armyworm, but also has the advantage of good stability. Compared with the reported sex attractant of fall armyworm, The effect of attracting moths is obviously enhanced.

Description

technical field [0001] The invention relates to the technical field of plant protection, more specifically, it relates to a sex lure for Spodoptera frugiperda and its preparation method and application. Background technique [0002] Spodoptera frugiperda (J.E.Smith), also known as Spodoptera frugiperda (J.E.Smith), belongs to Lepidoptera, is native to tropical and subtropical regions of the Americas, and is widely distributed in the American continent. It is an important local agricultural pests. With the increasing frequency of international trade activities, fall armyworm has invaded 44 African countries south of the Sahara, as well as India, Bangladesh, Sri Lanka, and Myanmar in Asia. In January 2019, fall armyworm invaded Yunnan Pu'er City in the province, then spread in more than 20 provinces, municipalities and autonomous regions in my country, and harm crops such as weeds, corn, rice, sorghum, sugarcane, etc. It is a harmful and powerful pest. It has miscellaneous fe...
