Problems solved by technology

[0003] At present, the green control technology of important mulberry pests (such as mulberry borer, mulberry caterpillar and mulberry looper) mainly focuses on the research on sex pheromone attractants, and corresponding sex attractant products have also been obtained. However, the insect sex information researched at home and abroad The attractants of natural attractants are all male adults, and there are few reports on attractant products targeting female moths, which leads to the lack of research and application of attractants for female adults, which in turn affects the comprehensive and sustainable control of pests

Embodiment 1

[0037] Y-type olfactory test of botanical attractant single product and composition on female moth of Mulberry borer

[0038] The test method and steps are as follows:

[0039] (1) Three single products of trans-3-hexen-1-ol, n-butyl acrylate and n-hexacane and trans-3-hexen-1-ol + n-butyl acrylate, trans -3-hexen-1-ol+n-hexacosane, n-butyl acrylate+n-hexacosane and trans-3-hexen-1-ol+n-butyl acrylate+n-hexacosane4 This composition was treated with 7 attractants of 60 ug / ul according to the mass fractions of trans-3-hexen-1-ol 1.16%, n-butyl acrylate 1.49%, and n-hexacane 4.26%.

[0040] (2) The behavior of the female moths of Mulberry borer was measured by Y-type olfactometer. Take the mated female moth (2-3 days old) as the test object, place the entire olfactory measuring device in an environment with uniform light, and the light intensity is not higher than 200 μmol / m 2 s; use a micro sampler to take 20 μL of the standard solution to be tested and drop it on a 3cm×3cm f...

Embodiment 2

[0044] Synergistic effect of botanical attractant single product and composition on mulberry borer food attractant

[0045] The test method and steps are as follows:

[0046] (1) Three single products of trans-3-hexen-1-ol, n-butyl acrylate and n-hexacane and trans-3-hexen-1-ol + n-butyl acrylate, trans -3-hexen-1-ol+n-hexacosane, n-butyl acrylate+n-hexacosane and trans-3-hexen-1-ol+n-butyl acrylate+n-hexacosane4 According to 1.16% of trans-3-hexen-1-ol, 1.49% of n-butyl acrylate, and 4.26% of n-hexacane, 7 attractants were prepared to treat with 60ug / ul respectively.

[0047] (2) The above-mentioned 7 attractants are respectively combined with the mulberry borer food attractant, and the combination of an equal amount of liquid paraffin and the mulberry borer food attractant is used as a contrast, and the field trapping effect of the above-mentioned 8 combination treatments on the mulberry borer is tested; Three repetitions were set up for each treatment, and the number of t...

Embodiment 3

[0051] Attraction test of different formulations of plant-derived attractants for female moths of Mulberry borer to lay eggs

[0052] The test method and steps are as follows:

[0053] (1) According to trans-3-hexen-1-ol 0.15%, n-butyl acrylate 0.21%, n-hexacane 0.54%; trans-3-hexen-1-ol 1.16%, n-butyl acrylate 1.49% ester, 4.26% n-hexacane; 6.52% trans-3-hexen-1-ol, 8.67% n-butyl acrylate, and 13.84% n-hexacane were formulated to 60ug / ul 3 attractant treatments.

[0054] (2) The above-mentioned 3 attractant treatments are placed equidistantly in the mulberry garden, and the same amount of liquid paraffin is used as a contrast to test the field trapping effect of the above-mentioned 4 attractant treatments on the mulberry moth; each treatment is set 3 replicates The number of trapped female moths was regularly recorded every day, and the lures were replaced every 3 days; the trapping experiment was carried out during the peak period of the occurrence of Mulberry borer adults...

Abstract

The invention discloses an attractant for female moths of mulberry moths as well as a preparation method and application of the attractant, and belongs to the technical field of pollution-free comprehensive control. Effective components of the attractant for the female moths of the mulberry moths comprise n-hexacodecane, trans-3-hexen-1-ol and n-butyl acrylate, and the attractant for the female moths of the mulberry moths has a remarkable attraction effect on female moths of the mulberry moths, so that the egg laying amount of the female moths in a mulberry field can be effectively reduced; therefore, the population number of mulberry moth larvae in a mulberry field and the harm to mulberries are reduced, the traditional chemical pesticide control frequency is reduced, a new way is provided for environment-friendly and efficient control of the mulberry moth damage to the mulberries, and the method has important significance in promoting high-quality development of silkworms and has high popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of pollution-free comprehensive prevention and control, and in particular relates to a mulberry borer female moth attractant and its preparation method and application. Background technique [0002] Mulberry borer [Diaphaniapyloalis (Walker)] belongs to Lepidoptera of Lepidoptera and Pyralidae of Moth family Pyralidae, and is one of the major pests of mulberry trees. Due to its characteristics of large reproduction, short reproductive cycle, obvious overlapping of generations, and difficulty in control, it is very easy to break out and cause disasters under suitable conditions, which seriously affects the sustainable development of sericulture industry. At present, production mainly relies on traditional chemical control methods to prevent and control it. While obtaining high control efficiency, it is also accompanied by pest resistance, environmental pollution, pesticide residues, human and animal safety, a...
