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

Abstract

The invention relates to a grassland spodoptera litura sex attractant and a preparation method and application thereof. The raw materials of the grassland spodoptera litura sex attractant comprise a main material and an auxiliary material. The main material comprises composite pheromone, a synergist, an antioxidant and a light stabilizer, and the composite pheromone comprises cis-9-tetradecenyl acetate, cis-11-hexadecenyl acetate, cis-7-dodecenyl acetate and cis-9-dodecenyl acetate; and the synergist comprises citric acid, malic acid, limonene and green leaf volatile matters. According to thesex attractant, the trapping effect of the sex attractant on the grassland spodoptera litura is improved through the synergistic effect of the raw materials, the sex attractant has the advantage of being good in stability, and compared with the reported grassland spodoptera litura sex attractant, the moth trapping effect 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...
