Problems solved by technology

However, with the emergence of pest resistance, the control effect will be significantly reduced. At the same time, the application of chemical pesticides will also affect the survival of natural enemies, cause a series of problems such as ecological environment damage and food quality and safety, which has become an important obstacle to the sustainable development of agriculture.

Embodiment 1

[0012] Embodiment 1 The preparation method of Spodoptera frugiperda sex pheromone fascination agent

[0013] A polyvinyl chloride capillary (PVC) (length 20cm x inner diameter 1.5mm) with slow release effect was selected as the carrier. The corn oil solution containing cis-8-tetradecene acetate was injected into a polyvinyl chloride capillary in a dose of 5-15 mg, and 2% of 2,6-di-tert-butyl-4-methylphenol ( BHT) as a stabilizer, after the completion, the two ends of the capillary are heated and sealed to make the Spodoptera frugiperda sex pheromone fascination agent lure core. Before the test, the lure core was placed in a -20 ℃ refrigerator and stored for later use.

Embodiment 2

[0014] Example 2 Field Biological Activity Determination Test

[0015] The lure core prepared in Example 1 was selected and hung in the corn field where the damage of Spodoptera frugiperda was relatively serious for testing. Three replicates were set for each of the above lure treatments. Table 1 shows the different doses, placement numbers and inhibition of mating rates.

[0016]

[0017]

[0018] The test results showed that cis-8-tetradecene acetate had different degrees of inhibition on the mating of Spodoptera frugiperda, and with the increase of the dose, the inhibition of mating became more obvious. When the dose exceeded 11 mg, the number of settings per hectare was At 500, the inhibition rate of mating was greater than 90%. At the same time, when the dose of cis-8-tetradecene acetate was 5 mg, the inhibition of mating rate was higher as the number of settings per hectare increased. Considering the cost, it is recommended that the content of cis-8-tetradecene ...

Embodiment 3

[0019] Example 3 Field release rate of Spodoptera frugiperda sex pheromone fascination agent

[0020] The lure core (cis-8-tetradecene acetate 5mg) prepared in Example 1 was selected, hung in the field, and the remaining cis-8-tetradecene acetate in the lure core was extracted every 15 days for a continuous period of time. Statistics for 4 months, and quantitative determination by gas chromatography. After 4 months, the content of cis-8-tetradecene acetate was still 1.54 mg ( figure 2 ), indicating that the field lasting period of the Spodoptera frugiperda sex pheromone fascination agent of the present invention is greater than 4 months, and can be used for the control of Spodoptera frugiperda.

[0021] The sex pheromone fascination agent of the invention can interfere with the mating communication between males and females of Spodoptera frugiperda, minimize the mating rate of adult insects, reduce the reproduction number, play the dual functions of interference and trapping...

Abstract

The invention discloses a method for controlling Spodoptera frugiperda by utilizing a sex pheromone trope, belonging to the field of biological control. The invention utilizes the synthetic sex pheromone fascination agent component cis-8-tetradecene acetate to prevent and control Spodoptera frugiperda by interfering with the information transmission between male and female moths of Spodoptera frugiperda. The Spodoptera frugiperda fascination agent of the invention can effectively reduce the mating rate between males and females, and generally can reduce the mating rate by more than 85%. At the same time, it has a long lasting effect, strong specificity, and is environmentally friendly, which is of great significance for the comprehensive management of Spodoptera frugiperda.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to an application of a sex pheromone fascination agent for controlling Spodoptera frugiperda. Background technique [0002] Spodoptera frugiperda is a member of the family Noctuidae, order Lepidoptera, native to tropical and subtropical America. According to data reports, Spodoptera frugiperda is a polyphagous pest that can harm 353 species of plants in 76 families, such as Gramineae, Solanaceae, Cruciferae, Caryophyllaceae, Compositae, etc. , rice, wheat, etc. Since the outbreak of Spodoptera frugiperda in Africa in 2016, it has become a major pest in Africa, America, Oceania and Asia, and has been recognized by the Food and Agriculture Organization of the United Nations as a globally important agricultural migratory pest. Introduced to my country from the China-Myanmar border in January 2019, it has spread to 129 counties in the province by the end of June...
