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

Abstract

The invention relates to the field of agricultural production storage, in particular to a repellant for lasioderma serricorne and a preparation method thereof. Tephrosia vogelli and borneol are used as main raw materials, calotropis gigantea leaf, aloe, living stephanotis, lemon essential oil, eucalyptus essential oil and salvia essential oil are used as auxiliary raw materials, repelling and killing effect of tephrosia vogelli on lasioderma serricorne is brought into full play, volatile insect-repelling ingredients in borneol are combined with insect-repelling effect of aloe and living stephanotis, the lemon essential oil, the eucalyptus essential oil and the salvia essential oil are used for blending, insect repelling and killing properties of the lemon essential oil and the eucalyptus essential oil are brought into full play, smell of all raw materials is excited fully through the salvia essential oil, and insect repelling effect of all raw materials on lasioderma serricorne is amplified to realize effect of fully repelling lasioderma serricorne. The repellent is prepared from pure natural raw materials, thereby being little in toxic and side effect and basically harmless to human body, and is low in toxicity, good in repelling effect and basically harmless to the human body.
