Embodiment 1

[0013] The preparation of embodiment 1 Spodoptera frugiperda high-efficiency attractant lure core:

[0014] The preparation method of the lure core of the high-efficiency fall armyworm attractant is that the n-hexane solution containing the fall armyworm attractant is added dropwise on the lure core (trans rubber head), and after the n-hexane solution volatilizes, a certain amount of The n-hexane solution was added dropwise on the lure, and after the n-hexane was completely volatilized, the lure containing the fall armyworm attractant was prepared, and the prepared fall armyworm lure was stored in a refrigerator at -20°C for later use.

[0015] Tests show that the high-efficiency attractant for fall armyworm disclosed by the invention can be accurately used for insect situation monitoring, mass trapping and mating interference of fall armyworm. The high-efficiency attractant for Spodoptera frugiperda provided by the invention is simple to prepare, easy to use, has strong trapp...

Abstract

The invention discloses an efficient attractant for spodoptera frugiperda as well as a preparation method and application of the efficient attractant. The spodoptera frugiperda attractant includes the components oflevo-alpha pinene and cis-3-hexene-1-alcohol in the mass ratio of (0.5-1): (1.3-4). The spodoptera frugiperda attractant is simple to prepare, and the raw materials are easy to obtain; the specificity is high, and the trapping effect is good; the attractant is harmless to human and livestock and environment-friendly; and the stress resistance is high, and use is convenient. The efficient attractant for the spodoptera frugiperda can be accurately applied to pest situation forecasting, mating interference and mass trapping of the spodoptera frugiperda, and has great significance in comprehensive treatment of the spodoptera frugiperda.

Description

technical field [0001] The invention belongs to the technical field of insect pheromone preparation, and in particular relates to an attractant for Spodoptera frugiperda and its preparation method and application. Background technique [0002] The fall armyworm Bemisia tabaci (Gennadius) belongs to the order Homoptera and belongs to the whitefly family. It is one of the most harmful invasive species in the world. During the invasion process, it caused devastating damage to many crops in China and other countries and regions. Different plants show different damage symptoms. Leafy vegetables such as cabbage and cauliflower suffer from shrunken, yellowed, and withered leaves; root vegetables such as radish suffer from albino color, tasteless, and weight loss; Ripe evenly. At present, the control of Spodoptera frugiperda mainly relies on chemical control. However, the use of a large number of chemical pesticides will not only make pests resistant to pesticides, but also pose a...
