A kind of repellant of tobacco beetle and preparation method thereof

Abstract

The invention relates to the field of agricultural product storage, in particular to a repellent for tobacco first and a preparation method thereof. The present invention uses edamame and borneol as main raw materials, supplemented with cerise leaf, aloe vera, African jasmine, lemon essential oil, eucalyptus essential oil, sage essential oil, fully exerts the effect of edamame on tobacco beetle repelling and killing, and the borneol in borneol Volatile insect repellent ingredients, combined with the insect repellent effects of aloe vera and African jasmine, and blended with lemon essential oil, eucalyptus essential oil, and sage essential oil to give full play to the insect repellent properties of lemon essential oil and eucalyptus essential oil, and through sage The essential oil fully stimulates the smell of all raw materials, amplifies the insect repelling effect of all raw materials on tobacco beetles, and achieves the effect of fully expelling tobacco beetles. Moreover, the repellent of the present invention is prepared from pure natural raw materials, has few toxic and side effects, and is basically harmless to the human body.

Description

technical field [0001] The invention relates to the field of agricultural product storage, in particular to a repellent for tobacco beetle and a preparation method thereof. Background technique [0002] Tobacco beetle Lasioderma serricorne (Fabricius) is an important stored pest, especially harmful to stored tobacco and its products. This beetle belongs to the family Coleoptera and is distributed all over the world with a very diverse diet. In order to prevent and control tobacco beetle, my country invests a lot of manpower and capital every year. The main control methods are as follows: fumigation: including traditional fumigation poisonous gas phosphine and methyl bromide, as well as new fumigants ethyl formate, carbon oxysulfide, sulfur Acyl fluoride, etc.; Physical control: including airtight packaging materials, diatomaceous earth, 60Co rays, hot air treatment, and modified atmosphere methods, etc.; Biological control: including release of golden bees, Greek tyrosal mit...

AI Technical Summary

Problems solved by technology

In addition to the fumigation method, the above other control measures are in the stage of exploration or experimentation, the main reason is that the effect is not ideal or the benefit is not significant

The long-term use of phosphine fumigation has caused serious resistance to tobacco A, and methyl bromide will be eliminated because it is difficult to degrade and will destroy the ozone layer; other new fumigants such as ethyl formate, carbon oxysulfide, sulfuryl fluoride, etc. are not allowed to use

The use of sealed packaging materials to isolate and prevent tobacco A has a great impact on tobacco quality; radiation prevention also has defects that affect tobacco quality, and the cost and application conditions are high, and the potential carcinogenic, teratogenic, and mutagenic risks to the human body have not yet been tested. Evaluation; the controlled atmosphere method has high requirements on the infrastructure of the smoke warehouse, so the cost is high; the seasonal limitation of temperature control control is too strong, and the application of biological control is still in its infancy; the sex attractant is a female attractant and can only trap and kill male insects , so the desired control effect cannot be achieved

[0003] At present, because chemical fumigation has the disadvantage of high toxicity, cinnamaldehyde-based tobacco first repellents are commonly used, such as patent application CN201810083640.1 (a tobacco first repellant and its preparation method, application), patent CN200810141573.0 (tobacco first repellent) Tobacco A repellent), etc., its repelling effect is more durable, but the effect is poor, especially when it is used in a large area, it cannot reach expectations. Therefore, in order to effectively prevent and control tobacco A, it is necessary to find a kind of tobacco with lower toxicity and repellent effect. Well, the repellant of tobacco beetle, which is basically harmless to the human body
