Embodiment 1

[0014] Mix 99.9% diatomite (200 mesh) and 0.1% allicin powder evenly, and dry to obtain the termite inert powder, with a water content of 0.1%.

[0015] In a plastic beaker with a diameter of 9 cm, put 30 termites in each beaker, evenly cover the beaker with moist vermiculite to 2 cm, and then evenly lay 1 mm, 2 mm, and 3 mm thick vermiculite on the vermiculite layer. The inert powder obtained in this embodiment; the control group was laid with sand grains of the same thickness on the vermiculite layer. Four experiments were repeated, and the experiment was carried out under dark conditions of (25±1)°C and (90±5)% RH, and termite penetration was regularly recorded. The penetration ability results are shown in Table 1.

Embodiment 2

[0020] Embodiment 2. Mix 99.5% diatomaceous earth (300 mesh) and 0.5% allicin powder evenly, and dry to obtain termite inert powder, and the water content is controlled at 10%, 25%.

[0021] In a petri dish with a diameter of 9 cm, an inert powder with a thickness of 3 mm and different humidity was uniformly spread in each petri dish, and sand grains with the same humidity and thickness were laid in the control group, and 30 S. black-breasted termites were placed in each petri dish. Four experiments were repeated, and the experiment was carried out under (25±1)°C, (90±5)%RH, dark conditions, and termite mortality was recorded regularly. Comparison of lethal effects between anhydrous inert powder and anhydrous sand figure 1 . See Table 2 for the lethal effects of different humidity inert powders on Termites termites.

Embodiment 3

[0028] Example 3. Mix 99% diatomaceous earth (400 mesh) and 1% allicin powder evenly, and dry to obtain termite inert powder, and the water content is controlled at 0.1%-1%.

[0029] Before the indoor floor decoration, use the powder spraying device to evenly spray the inert powder on the ground with a thickness of 3-5mm, then spread the moisture-proof mat, and finally cover the floor.

[0030] When it is found that the wooden components in the room are harmed by termites, the surface of the wooden components can be punctured, sprayed with inert powder, and the present embodiment is directly sprayed on the surface of termites, so that the control effect is better.

Abstract

The invention relates to inert powder capable of preventing and controlling termites. The inert powder is formed by mixing diatomite with the mass percent of 99 to 99.9 percent and allicin powder with the mass percent of 0.1 to 1 percent. The inert powder disclosed by the invention has good capability of adsorbing epidermal lipids of insects, and makes contact and friction with epidermis of the termites, so that the epidermis of the termites are damaged, and the termites dehydrate to die within 4 to 5 hours. According to the inert powder disclosed by the invention, hazard of the termites on building materials can be effectively blocked; the inert powder with the thickness of 3mm or above is uniformly paved; once the termites make contact with the inert powder disclosed by the invention, the action is seriously hindered, the termites cannot penetrate through the inert powder and only can go round or roll around, and then immediately die. The inert powder taking the diatomite and the allicin powder as raw materials, disclosed by the invention, has better effects of touching out and repelling the termites and a broad market prospect, is long in lasting period, safe to mammals, aquatic animals and birds, and is easy to degrade in environment, so that the pollution to the environment is avoided; the inert powder has the characteristics of long effect, no toxicity, environment friendliness, low cost, simplicity and convenience in operation and the like.

Description

technical field [0001] The present invention relates to an inert powder capable of controlling termites. Background technique [0002] With the progress of society and the improvement of people's living standards, people began to carry out large-scale decoration and renovation of houses, which provided good conditions for the survival and reproduction of termites, and the harm of termites in houses has become increasingly serious. At present, chemical pesticides are mainly used to control termites in interior decoration, which poses a huge safety threat to the living environment. The development of efficient, non-toxic and environmentally friendly termite control technology has become an urgent need for interior decoration termite control. [0003] As a natural mineral, diatomite is widely used in the control of stored grain pests. There are many diatomaceous insecticidal products at home and abroad, such as Dryacide in Australia and Puliangtai in China. Chinese invention...
