Problems solved by technology

However, the various cotton bollworm control products or control technologies currently used are relatively independent and require their own specific supporting facilities. Need to have matching traps, etc., which will undoubtedly increase the cost of cotton bollworm control, and the control effect still needs to be improved

Embodiment 1

[0033] The control method of embodiment 1 cotton bollworm

[0034] The present embodiment provides a kind of control method of cotton bollworm, specifically as follows:

[0035] Below the lampshade of the LED insecticidal lamp whose luminous wavelength is 380-420nm (purple), hang the Kubode biological food attractant, and the vertical distance between the food attractant and the lampshade of the LED insecticidal lamp is 12cm. The bottom of each insecticidal lamp hangs 3 bags of Kubode biological food attractant lure wick finished products, which are hung under the insecticidal lampshade in a triangle shape. The lowest end of the LED insecticidal light source is 1 meter higher than the top of the crop, and the interval between every two LED insecticidal lights is 40 meters.

[0036] Insecticidal lamps were used on April 25th, and food attractants were hung before the first generation of eclosion of the local cotton bollworm. Insect lamps, all the suspended food attractants ar...

[0044] Experimental Example 1 Trapping and Killing Effect of Cotton Bollworm

[0045] In a peanut field in Xinxiang City, Henan Province, the control methods of bollworm in Example 1 and Comparative Example 1 were used for control.

[0046] Starting to use LED insecticidal lamps on April 25th, embodiment 1 began to hang food attractants at the same time, and counted the number of cotton bollworms from late April to mid-August. The analysis results showed that compared with using LED insecticidal lamps alone In contrast, adding food attractants can significantly increase the trapping quantity of cotton bollworm, especially when the adult occurrence peak of cotton bollworm, the effect is more obvious. The control method of embodiment 1 increases 40.96% ( figure 1 ).

[0047] Experimental Example 2 Trapping and Killing Effect of Noctuidae Pests

[0048]In a peanut field in Xinxiang City, Henan Province, the control methods of bollworm in Example 1 and Comparative Example 1 were used for control.

[0049] Starting to use LED insecticidal lamps on April 25th, embodiment 1 began to hang food attractants at the same time, and counted the quantity of all Noctuidae pests that were lured from late April to early August (the main species included cotton bollworm, small Cutworms, Noctuid moths, etc.), the analysis results show that compared with using LED insecticidal lamps alone, adding food attractants can significantly increase the number of adults trapped by Noctuidae pests, especially at the peak of adult occurrence. obvious. The control method of embodiment 1 increases 32.12% ( figure 2 ).

Abstract

The invention relates to the technical field of plant protection, in particular to a method for preventing and controlling cotton bollworms through combined use of an insecticidal lamp and a phagostimulant. The single-purple-light insecticidal lamp and the phagostimulant are combined to trap and kill cotton bollworm adults. The single-purple-light insecticidal lamp and the biological phagostimulant containing aromatic substances can generate a synergistic interaction effect, so that the trapping and killing effect on the cotton bollworms is remarkably improved. Moreover, by means of a facilityof the insecticidal lamp, the phagostimulant is hung below the insecticidal lamp, a trap matched with the phagostimulant does not need to be additionally installed, the prevention and control methodis simple and easy to implement, and the prevention and control cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of plant protection, in particular to a method for controlling cotton bollworms through the combined use of insecticidal lamps and food attractants. Background technique [0002] Cotton bollworm is an important agricultural pest in the world. Its host plants are of many types. In addition to harming cotton, it can also harm various cultivated crops such as corn, wheat, sorghum, soybean, peanut, tomato, etc. The planting of transgenic insect-resistant cotton can significantly reduce the bollworm population on insect-resistant cotton and other host crops around it. However, when the planting ratio of transgenic insect-resistant cotton is low, and the planting area of ​​other host crops (such as corn, vegetables, etc.) is high, it will still lead to a high occurrence base of cotton bollworm, which seriously endangers host crops other than insect-resistant cotton. . [0003] In recent years, more and more atte...
