Embodiment 1

[0035] Embodiment 1, the preparation of clove essential oil

[0036] A preparation method and application of clove essential oil for killing termites, characterized in that: the preparation method steps of clove essential oil are: raw material selection-material crushing, weighing-apparatus selection, distillation-solvent extraction, concentration-finished product packaging ;

[0037] Step 1: Raw material selection

[0038] Choose more than 50 grams of dry, undamaged clove buds;

[0039] Step 2: Material crushing and weighing

[0040] After the selected lilac flower buds are crushed to 20 meshes by machinery, take by weighing 50 grams of it, and set aside;

[0041] Step 3: Equipment selection, distillation

[0042] Put 50 grams of pulverized clove buds into a 1000ml retort, and distill for 4-6 hours by steam distillation;

[0043] Step 4: Solvent extraction, concentration

[0044] Extract the oily substance in the water phase of the distillate with anhydrous petroleum et...

Embodiment 2

[0047] Embodiment 2, clove essential oil component analysis

[0048] Through GC-MS analysis, the main component of clove essential oil is eugenol. At the same time, there are also eugenol analogs, such as: methyl eugenol, acetyl eugenol, isoeugenol, methyl isoeugenol and acetyl isoeugenol, the chemical structure is as figure 1 shown.

[0049] In embodiment 2, the active experiment of clove essential oil

[0050] Refer to the termiticidal activity assay used by Kang et al. (1999). Put the qualitative filter paper (Φ9cm) flatly into the Petri dish (Φ9cm), and dilute clove essential oil into 4 different concentrations with acetone. Use a 1ml pipette gun to pipette 1ml of the drug dilution from the outer edge of the petri dish to the inside and evenly drop it on the filter paper, and then cover it after drying for a while. Each dish received 30 robust worker ants of the termite termites. The test was carried out at (25±1)°C, 85±5%RH in the dark, observed once a day, and the d...

Embodiment 3-8

[0052] Embodiment 3-8, operation method is the same as embodiment embodiment 1.

Abstract

The invention discloses a preparation method and applications of a termite killing preparation namely clove essential oil. The clove essential oil is prepared by the following steps: choosing raw materials, grinding raw materials, weighing, choosing utensils, carrying out distillation, extracting the raw materials by a solvent, carrying out concentration, and encapsulating the finished product. The main components that kill termites in clove essential oil are eugenol and eugenol analogues (methyl eugenol, acetyl eugenol, isoeugenol, methyl isoeugenol, and acetyl isoeugenol). The termite killing rate is high, when the concentration of clove essential oil is 50 to 200 [mu]g / g; the eugenol concentration is 25 to 100 [mu]g / g, the methyl eugenol concentration is 50 to 200 [mu]g / g, the acetyl eugenol concentration is 25 to 100 [mu]g / g, the isoeugenol concentration is 50 to 200 [mu]g / g, the methyl isoeugenol concentration is 50 to 200 [mu]g / g, and the acetyl isoeugenol concentration is 50 to 200 [mu]g / g. The clove essential oil has the advantages of good using effect, safety to human body, no pollution, no toxic residue, and simple manufacturing technology.

Description

technical field [0001] The invention relates to the technical field of development and application of natural plant essential oils for termite control and contact killing preparations, in particular to a preparation method and application of clove essential oils for termite killing preparations. Background technique [0002] Termites are a worldwide recognized pest, which mainly harm the wooden structures of buildings, dams and reservoirs, crops, landscaping, corrosion of cables and communication equipment, etc. As the global climate warms, the harm of termites is increasing. However, termites are stealthy, making them difficult to spot until the wood is severely damaged. According to statistics, in 2010, the global economic loss caused by termites reached about 40 billion US dollars, and the annual economic loss caused by termites in my country was as high as 3 billion yuan. Therefore, termite control seems very urgent. [0003] Although there are many ways to prevent an...
