Embodiment 1

[0051] Example 1: Monitoring of Spodoptera frugiperda in Huadu District, Guangzhou, Guangdong

[0052] 1. The formula of the sex attractant of Spodoptera frugiperda: cis-9-tetradecene acetate, cis-11-hexadecene acetate, cis-7-dodecene acetate according to three groups Proportionally configured to obtain Spodoptera frugiperda sex attractant 1, cis-9-tetradecene acetate, cis-11-hexadecene acetate, cis-7-dodecene acetate, cis -9-dodecene acetate is configured according to the four-component scheme to obtain the fall armyworm sex attractant 2, and makes the fall armyworm sex attractant lure core; the carrier used is a polyvinyl chloride tube;

[0053] 2. Install the trapping device: the trap is preferably composed of a transparent insect collecting bucket, an opaque inverted hot pot-shaped insect guide and a cover. Combine the insect collecting bucket with the insect guide, combine the insect guide with the cover, and put the lure Put the flower basket component in the middle of ...

Abstract

The invention discloses a Spodoptera frugiperda sex attractant, a matched trapping device and an application method. The pheromone of the Spodoptera frugiperda sex attractant is prepared by combiningcis-9-tetradecenyl acetate, cis-11-hexadecenyl acetate, cis-7-dodecenyl acetate and cis-9-dodecenyl acetate according to different proportions, and a sustained-release carrier material comprises a rubber plug, a polyethylene sustained-release bag, a polyvinyl chloride sustained-release bag, a polyvinyl chloride pipe and the like. The matched trapping device comprises a trapping device body and a support rod, wherein the trapping device body comprises a transparent pest collector, a non-transparent pest guide device and a cover. When the sex attractant and the trapping device are used, the three parts of the trapping device body are assembled, the sex attractant is placed into a attractant mounting component on the trapping device body cover, the trapping device body is fixed onto the support rod, and the height of the trapping device body is adjusted according to the crop height to guarantee that the bottom of the trapping device body is constantly higher than the top of crops so as toperforming Spodoptera frugiperda trapping monitoring and Spodoptera frugiperda control.

Description

technical field [0001] The invention relates to the field of plant protection, in particular to the design and use method of a sexual attractant lure core capable of trapping Spodoptera frugiperda and a matching trap. Background technique [0002] Spodoptera frugiperda (J.E.Smith), an insect of the genus Spodoptera frugiperda in the family Noctuidae of the order Lepidoptera. It is a major migratory agricultural pest native to tropical and subtropical regions of America. It is polyphagous, but it has a clear preference for grasses. The most common damage to weeds, corn, rice, sorghum, sugar cane and other crops; in January 2019, fall armyworm invaded Pu'er City, Yunnan Province, my country. As of mid-August, it has harmed corn in more than 20 provinces, municipalities and autonomous regions in my country . According to reports, the insect invaded Africa in 2017 and caused a loss of 21% to 53% of the local corn yield. It is a very harmful pest. [0003] The insect attractant...
