Spodoptera frugiperda sex attractant, matched trapping device and application method

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...

AI Technical Summary

Problems solved by technology

[0006] In terms of sex pheromones, domestic research on sex pheromones of fall armyworm is still in a blank stage, and there is a lack of mature pheromone products that can effectively trap fall armyworm. There is no experimental data support for the trapping effect of the insect. In terms of the method of use, the hanging height of the trap and the hanging method of the lure wick lack the use index, which affects the trapping effect
