Problems solved by technology

However, most of the above-mentioned studies stayed at the bioassay stage of plant crude extracts, and only Masatoshi Hori reported the repellent activity of (-)-perillaldehyde and hinokitiol (also called hinokitiol) on tobacco A in 2004 and 2005, respectively. , published in "Applied Entomology and Zoology" (Applied Entomology and Zoology), but plant-derived tobacco beetle behavior regulators have not yet seen products on the market

Embodiment 1

[0015] Example 1 First prepare 1% agar sol, then add 1 part of methylparaben at 85°C for co-melting, and when room temperature is cooled to 40°C, mix 5 parts of cinnamaldehyde and methyl cinnamate in parts by volume 5 parts of ester, shake vigorously until solidified. Divide the prepared repellent into 8mL small glass bottles, and open the bottle caps when using.

Embodiment 2

[0016] Example 2 First prepare 8% agar sol, then add 2 parts of methylparaben at 85°C for co-melting, when room temperature is cooled to 40°C, mix 50 parts by volume of cinnamaldehyde, methyl cinnamate 10 parts of ester, 40 parts of ethyl cinnamate, shake vigorously until solidified. Divide the prepared repellent into 8mL small glass bottles, and open the bottle caps when using.

[0017] The formulations of the repellents in Examples 3 to 8 are shown in Table 1, and the others are the same as in Example 1.

Abstract

The invention aims to overcome the defects of current Lasioderma serricorne (Fabricius) control products or technology and screen a safe, efficient, economic and simple Lasioderma serricorne (Fabricius) repellant formula. The Lasioderma serricorne (Fabricius) repellant is prepared by fusing cinnamic aldehyde, cinnamic acid derivatives or a mixture of the cinnamic acid derivatives, an assistant and a carrier. The Lasioderma serricorne (Fabricius) repellant is prepared by 5-50 parts of cinnamic aldehyde, 5-50 parts of cinnamic aldehyde derivatives or cinnamic acid derivatives, 1-2 parts of assistant and 10-500 parts of carrier by volume. The Lasioderma serricorne (Fabricius) has the advantages of strong activity, long efficacy duration, low possibility to deteriorate, easy use, convenient storage and transportation and the like, and overcomes the defect of high toxicity of chemical fumigants and complies with the requirements of green tobacco production and processing.

Description

Technical field: [0001] The invention belongs to the technical field of agriculture, and in particular relates to a repellent. Background technique: [0002] Tobacco beetle Lasioderma serricorne (Fabricius) is an important stored product pest, especially harmful to stored tobacco leaves and its products. This beetle belongs to the family Anobiidae of the order Coleoptera. It is distributed all over the world and has a very mixed diet. In order to prevent and control Tobacco A, our country invests a lot of manpower and resources every year. The main prevention and control methods are as follows. Fumigation: including traditional fumigating toxic gases phosphine and methyl bromide, as well as new fumigants ethyl formate, carbon oxysulfide, sulfuryl fluoride, etc.; physical control: including sealed packaging materials, diatomaceous earth, 60 Co ray, hot air treatment, and modified atmosphere, etc.; biological control: including the release of the golden beetle, Greek tyropha...
