The mass ratio of the barley malt alkali to the Penibruguieramine A is 1:40-40: 1. The formula of the invention is natural active substance, has low toxicity, safety and environmental protection, and has a certain synergistic repellent effect through the barley malt alkali and the Penibruguieramine A.

Description

Ant repellent

Technical Field

The invention relates to an ant repellent.

Background

Ants are the most widely distributed, diverse and numerous social insects on earth, 12199 existing species have been described worldwide, and a few new species are discovered and published each year. In the long evolution process, ants cooperate with plants, microorganisms and other animals to play an important role in maintaining ecological balance. For example, the mutual interest between ants and plants, plants attract ants by providing ants with food (food bodies), ant fungus (domania) and honeydew, and the ants serve as their "convoy" to prevent and reduce the damage of other phytophagous animals except the honeydew insects to the plants. However, some ants not only cause certain harm to animals and plants, pollute the environment and destroy buildings, but also attack human beings, disturb human life and influence health. The invasion of solenopsinvicta invicta is one of the most dangerous harmful invasion organisms in the world, often attacks human beings, and after a human body is stinged by the solenopsinvicta invicta, the skin is red, swollen and inflamed to generate blisters, so that secondary infection is easily caused if the human body is not paid attention to sanitation, and a few people can generate anaphylactic shock and even die due to the allergy to acid toxin in venom. The little yellow ants (Monomorium pharaonis) are common indoor ant species, can disturb normal life of people and cause anaphylactic reaction, and can spread and cause diseases. In recent years, reports about invasion of the little yellow ants into high-rise rooms are frequently available, and the events that the little yellow ants invade rooms and bite people are all related to Beijing, Shaanxi, Shandong, Henan, Gansu, Hebei, Zhejiang and the like. Ants are really troublesome to remove, the ants seen by residents are generally worker ants, and even if they can be killed by common insecticides, the effect is limited because a large number of ants in the ant nest are not killed. The existing ant control method mainly comprises physical control and chemical control, wherein the chemical control is a commonly adopted method.

Teratogenesis and carcinogenesis pose a threat to the environment and human health. Plant-derived repellents, unlike chemical insecticides, are intended to repel but not kill insects, and are of positive significance in protecting biological diversity and environmental and human safety concerns. With the improvement of human environmental protection consciousness, the research and development of the ant repellent which is environment-friendly, efficient, low-toxicity and low-resistance is very important. The botanical repellent is derived from natural plants, is environment-friendly and degradable, is the key point of development and research, and a great deal of experimental work is carried out on people for searching the botanical ant repellent, but the botanical ant repellent is still insufficient on the whole, and the ant repellent mechanism is not clear yet, so that a great deal of work needs to be completed by scientific researchers together.

Disclosure of Invention

Aiming at the problems in the prior art, the ant repellent provided by the invention is a brand-new plant-source ant repellent, has a good repellent effect, is non-toxic, safe and environment-friendly.

An ant repellent contains barley malt alkali and Penibruguieramine A as effective components (1-20 wt.%), and water as residual component.

The mass ratio of the barley malt alkali to the Penibruguieramine A is 1:40-40: 1.

The formula of the invention is natural active substance, has low toxicity, safety and environmental protection, and has certain synergistic repellent effect through the barley malt alkali and the Penibruguieramine A, and particularly the barley malt alkali and the Penibruguieramine A have surprising repellent effect in the range of 25-30: 1.

Detailed Description

The Penibruguieramine A provided by the invention has the following structural formula:

is a new skeleton with 3, 5-diformyl-isoamylphloroglucinol-benzidine separated from eucalyptus fruit,

the preparation method can be referred to as the following documents:

Penibruguieramine A, a Novel Pyrrolizidine Alkaloid from theEndophytic FungusPenicilliumsp. GD6 Associated with Chinese MangroveBruguiera gymnorrhiza

. Org. Lett., 2014,16(5), pp 1390–1393。

hordenine CAS: 539-15-1.

Determination of Ant repelling Activity

The test insects are that the little yellow ant is induced outdoors or the adult worker ant is obtained from the ant cave and is put in a barrel for feeding under the conditions that the laboratory temperature is 25-29 ℃ and the relative humidity is 60-80%.

The activity determination method comprises selecting 20 mung bean seeds with similar shape and size, dividing into 2 groups (10 seeds in each group), soaking in ethanol solvent (control) without medicament and solution (treatment) containing medicament for 1min, air drying, 3min later placing into a culture dish with diameter of 9cm (the edge of the culture dish is coated with a mixture prepared from 80% vaseline and 20% liquid paraffin in advance to prevent ants from climbing out), symmetrically placing the control and treated mung bean seeds at two sides, arranging 10 seeds into two rows, 5 seeds in each row, and arranging the row spacing of 0.5cm and the distance between mung bean seeds of 0.1 cm. 20 workers of the yellow ant were removed from the rearing bucket and transferred to the center of the petri dish at the same time. After 2min, two persons start to observe simultaneously and respectively record the times of ants passing through the contrast and the mung bean seed treatment, and the observation time is 2 min.

And calculating the ant repelling rate, wherein R = [ (C-T)/(C + T) ]. times.100%. In the formula, R represents the repelling rate, C represents the number of times that the little yellow house ant passes through the control mung bean, and T represents the number of times that the little yellow house ant passes through the treatment mung bean.

And (3) test results:

tests show that the single barley malt alkali and the Penibruguieramine A have certain ant repelling effect but not good enough, the mixing proportion of the barley malt alkali and the Penibruguieramine A improves the effect to a certain extent but not obvious and improves the effect by about 5-10%, but the barley malt alkali and the Penibruguieramine A have a surprising repelling effect in the range of 25-30:1, and the repelling activity of the mixed liquid is greatly enhanced in the range of the proportion, so that the mixed liquid has a remarkable repelling effect.

Claims
