Description
Technical Field
The invention belongs to the technical field of insect pheromone preparation, and particularly relates to a spodoptera frugiperda attractant and a preparation method and application thereof.
Background
Spodoptera frugiperda bemis tabaci (genocarpus) belongs to the homoptera and whitefly families, is one of the most harmful invasive species in the world, and causes devastating damage to many crops in China and other countries and regions during the invasion process. Different harmful symptoms are shown to different plants, and leaf vegetables such as cabbage and cauliflower have damaged leaves, are withered, yellowed and withered; damage of root vegetables such as radish shows whitening, tasteless, and weight loss; fruits and vegetables such as tomatoes are damaged, and fruits are not ripe uniformly. At present, chemical control is mainly used for controlling Spodoptera frugiperda. However, the use of a large amount of chemical pesticides not only can cause the pests to generate drug resistance, but also can threaten the safety of human beings and the environment.
The insect sex pheromone is an extremely trace chemical substance which is secreted and released by the gonad of an adult female moth, has strong attraction effect on the same species and the opposite individual and helps the same species of insects to mate successfully, and is a biological pesticide with great development prospect. Spodoptera frugiperda sex pheromone has the functions of monitoring population, interfering mating, trapping adults and the like. The sex pheromone of the Spodoptera frugiperda is utilized to carry out green prevention and control, and the Spodoptera frugiperda has the advantages of low usage amount, high biological activity, strong specificity, no harm to natural enemies, no generation of drug resistance and the like; and can be combined with other biological pesticides such as natural enemy insects, bacteria, fungi or metabolites thereof to comprehensively control Spodoptera frugiperda. The method utilizes the semiochemical to regulate and control the insect behaviors, has the advantages of small using amount, convenient use, strong specificity and environmental friendliness. The components and the use proportion of the Spodoptera frugiperda attractant are mastered, and the Spodoptera frugiperda attractant can be accurately used for the condition prediction, the interference mating and the mass trapping of Spodoptera frugiperda, so that the ideal effect of comprehensively treating Spodoptera frugiperda is achieved.
The invention content is as follows:
in view of the above, the present invention aims to provide a spodoptera frugiperda high-efficiency attractant and elucidate the use of the spodoptera frugiperda high-efficiency attractant, so as to improve the effect of comprehensively treating spodoptera frugiperda.
The Spodoptera frugiperda high-efficiency attractant comprises levo-alpha pinene and cis-3-hexenal. Wherein the mass ratio of the Spodoptera frugiperda high-efficiency attractant is as follows:
the Spodoptera frugiperda attractant is feasible, and the mass ratio of the levorotatory-alpha pinene to the cis-3-hexenal is 0.5-1: 1.3-4.
Preferably, the mass ratio of the levo-alpha pinene to the cis-3-hexenal in the spodoptera frugiperda attractant is 0.65-1: 1.2-3.
Preferably, the mass ratio of the levo-alpha pinene to the cis-3-hexenal in the spodoptera frugiperda attractant is 1: 3
The preparation method of the spodoptera frugiperda efficient attractant core is characterized by comprising the following steps: dripping n-hexane solution containing spodoptera frugiperda attractant on a lure core (a trans-rubber head), dripping a certain amount of n-hexane solution on the lure core after the n-hexane solution is volatilized, preparing the lure core containing the spodoptera frugiperda attractant after the n-hexane is completely volatilized, filling the prepared lure core into an aluminum foil, sealing, and refrigerating at-20 ℃ for later use.
Above-mentioned meadow spodoptera attractant lures application of core in traping the meadow spodoptera, during the use, will equip the trapper that the meadow spodoptera attractant lures the core, hang in the area that takes place or can take place the harm of meadow spodoptera, be used for the entomogenous fungi monitoring of meadow spodoptera, trap in a large number and disturb the mating, the trapper be triangle-shaped trapper.
Compared with the prior art, the invention has the following excellent effects: the Spodoptera frugiperda high-efficiency attractant provided by the invention is simple to prepare and easily available in raw materials; has strong trapping ability, long lasting period and prevention and control effect lasting for more than 30 days; the specificity is strong, and the Spodoptera frugiperda cannot generate resistance; is harmless to human and livestock and environment-friendly; strong stress resistance and convenient use. The invention can be accurately applied to the insect situation prediction, the interference mating and the mass trapping of the Spodoptera frugiperda and has important significance for the comprehensive Spodoptera frugiperda.
Detailed Description
The following detailed description of specific embodiments of the invention is provided, but it should be understood that the scope of the invention is not limited to the specific embodiments.
Example 1 preparation of spodoptera frugiperda efficient attractant core:
a preparation method of a spodoptera frugiperda efficient attractant core comprises the steps of dripping n-hexane solution containing a spodoptera frugiperda attractant on an attractant core (a trans-rubber head), dripping a certain amount of n-hexane solution on the attractant core after the n-hexane solution volatilizes, preparing the attractant core containing the spodoptera frugiperda attractant after the n-hexane completely volatilizes, and storing the prepared spodoptera frugiperda attractant core in a refrigerator at the temperature of-20 ℃ for later use.
Experiments show that the Spodoptera frugiperda high-efficiency attractant disclosed by the invention can be accurately used for monitoring the insect situation of Spodoptera frugiperda, and trapping and interfering mating in a large quantity. The Spodoptera frugiperda high-efficiency attractant provided by the invention is simple to prepare, convenient to use, strong in trapping capability and good in stability; strong specificity, no resistance, no harm to natural enemies, no toxicity to people and livestock and environmental protection.
