Embodiment 1

[0037] Take by weighing α-humulene (38%), buccalyl alcohol (17%), β-caryophyllene (25%), caryophyllene (20%) respectively according to mass content, add up to 24g, use 6.3g ethyl acetate Solution dissolves, adds 2.8g Tween, dissolves, and according to routine process, is made to be used for controlling the insecticide of fall armyworm, then will add acetone dilution in the prepared insecticide for controlling fall armyworm, Make the concentration of bulk drug be 1.5%. Finally, the biological activity of the diluted biopesticide was measured indoors on Spodoptera frugiperda by spot method. After 48 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 76.2%.

Embodiment 2

[0039] Take by weighing α-humulene (16%), buccal alcohol (28%), β-caryophyllene (38%), caryophyllene (8%), α-pinene (10%) respectively according to mass content, A total of 32g is dissolved with 9.5g ethanol, and 4.5g of emulsifying agent etc. are added therein, according to conventional technology, the insecticide that is used to control Spodoptera frugiperda is made, and then the prepared insecticide for controlling Spodoptera frugiperda is used to control Spodoptera frugiperda Add acetone to dilute the insecticide so that the concentration of the bulk drug is 16%. Finally, the biological activity of the diluted biopesticide was measured indoors on Spodoptera frugiperda by spot method. After 48 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 100%.

Embodiment 3

[0041] Take by weighing α-humulene (35%), buccalyl alcohol (5%), β-caryophyllene (19%), caryophyllene (25%), α-pinene (16%) respectively according to mass content, Totally 102g, dissolve with 54g acetone, add emulsifying agent Span etc. 50g therein, according to routine process, make the insecticide that is used to control fall armyworm, then with the prepared insecticide for controlling fall armyworm Add acetone to dilute the insecticide so that the concentration of the bulk drug is 8.0%. Finally, the biological activity of the diluted biopesticide was measured indoors on Spodoptera frugiperda by spot method. After 48 hours, the number of dead and alive insects in each treatment was investigated, and the control effect was 96.4%.

Abstract

The invention discloses a compound biological insecticide for controlling Spodoptera frugiperda. The insecticide includes sesquiterpenoids, and the sesquiterpenes are composed of the following substances in mass percentage: α-Humulus 5-40% ene; 5-40% buccal alcohol; 0-40% β-caryophyllene; 5-30% caryophyllene; 0-25% α-pinene. When the above insecticides are applied: water is added to the compound biological insecticide for controlling Spodoptera frugiperda under normal temperature stirring, and the insecticide is diluted to a concentration of 0.5-30wt% of sesquiterpenoids before spraying . The present invention is the first discovery that sesquiterpene compounds such as pothol and caryophyllin are used to control the biological activity of Spodoptera frugiperda, and it is the first time that they are formulated into compound biopesticides for the control of Spodoptera frugiperda.

Description

technical field [0001] The invention relates to a compound biological insecticide preparation in the technical field of pesticides and a preparation method thereof, in particular to a compound insecticide containing sesquiterpenoids for controlling alien invasive species - Spodoptera frugiperda and its application . Background technique [0002] Spodoptera frugiperda, commonly known as the demon moth, originated in the tropical and subtropical regions of America. It has the characteristics of strong migratory ability, wide host range, serious damage, and difficult prevention and control. pests. It was introduced into Yunnan Province of my country on January 13, 2019. After April, the insect spread relatively rapidly in the southern corn area of ​​my country; on May 9, the Planting Management Department of the Ministry of Agriculture and Rural Affairs, together with the National Agricultural Technology Extension Service Center, notified the grassland The harm and occurrence ...
