Problems solved by technology

When the larvae are infested, the host leaves are often bitten into nicks or holes, resulting in loss of yield and quality
At present, my country's control of silver moth mainly relies on chemical pesticides such as imidacloprid, but the excessive application of chemical pesticides has brought a series of negative effects such as ecological environment safety, food safety, and drug resistance.

Embodiment Construction

[0021] Our field investigations found that the silver moth will visit the flowers of various plants at night to feed on nectar. To this end, we analyzed the aroma components of a variety of flowers favored by Spodoptera spp. through gas chromatography-mass spectrometry, and screened out three substances with moth-attracting activity through gas chromatography-antennary potential coupling instrument and insect olfactory instrument. Furthermore, through repeated combination verifications in field experiments, a silver ingot moth food attractant composition with excellent attractant effect was finally obtained.

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific experiments.

[0023] The trapping experiment adopts the food attractant lure of silver ingot moth, as mentioned above, it is a polyethylene bottle lure. A polyethylene bottle...

Abstract

The invention relates to the technical field of pest attractants, in particular to a food attractant for Macdunnoughia crassisigna. The food attractant is developed on the basis of flower fragrance, is composed of three components including 2-phenylpropanal, phenethyl alcohol and cis-3-Hexenyl tiglate, has a remarkable attraction effect on Macdunnoughia crassisigna in the field, can effectively attract male and female Macdunnoughia crassisigna at the same time, can be used for population dynamic monitoring or centralized control of Macdunnoughia crassisigna, and has important significance on comprehensive treatment of Macdunnoughia crassisigna. The food attractant has the advantages of high efficiency, small dosage, no toxicity to human and livestock, long lasting period, no resistance generation and the like, and is a novel environment-friendly green prevention and control technology.

Description

technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to a food attractant for silver moth and a preparation method thereof. Background technique [0002] Macdunnoughia crassisigna Warren, Lepidoptera, Noctuidae, distributed in Northeast China, North China, East China, Northwest China, Tibet and other regions. Its larva is an important foliar pest with a wide range of hosts, including soybeans, eggplants, burdocks, chrysanthemums, and carrots and other cruciferous plants. When the larvae are infested, the host leaves are often bitten into nicks or holes, resulting in loss of yield and quality. At present, my country's prevention and control of Spodoptera mainly relies on chemical pesticides such as imidacloprid, but the excessive application of chemical pesticides has brought a series of negative effects such as ecological environment safety, food safety, and drug resistance. Therefore, it is necessary to devel...
