Description

Ancient building termite control method

technical field

The invention relates to the technical field of ancient buildings, in particular to a method for preventing termites in ancient buildings.

Background technique

At present, there are still a large number of ancient buildings in some ancient cities and tourist cities in China. These ancient buildings have been vigorously protected by relevant government departments, and some have even become cultural heritage. Ancient buildings are mainly wooden frame structures, that is, wooden columns and beams are used to form the frame of the house. However, with the passage of time, wooden columns and beams are easily damaged, damaged, and decayed by termites under the influence of the environment. Therefore, how to effectively prevent and control termites has become the focus of maintenance work.

Defects of prior art: At present, the mechanical excavation ant nest method prevention and control technology that termite control mainly adopts is mainly to find the feeding passage near the termite feeding point, follow the ant passage to the main nest, catch the king and queen, Excavate the fungus garden, and then backfill it with medicine. However, this method not only requires a large amount of excavation, but also leaves engineering sequelae if the backfill soil is not handled well. termite hazards, and the hidden dangers cannot be completely eradicated; the termite bait control technology is mainly to put "mirex" and other chemical agents, which are not only highly toxic to humans and animals, but also difficult to degrade under natural conditions. The bioaccumulation characteristics and volatile characteristics affect the local, regional and even global environment.

detailed description

In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below in conjunction with the accompanying tables and specific embodiments.

Example 1

A kind of ancient building termite control method is carried out according to the following steps:

Dig a 4m x 3m wide ditch around the outer floor of the outer wall of the ancient building, spray termite control drugs in three layers, and spray a layer of termite control drugs to cover a layer of soil; The inside and outside of the outer wall of the first floor, the columns and the wall surface within 1 meter of all the inner walls shall be sprayed with termite control drugs; the inner and outer sides of the outer walls, columns and all the inner walls of the second floor and above of the ancient buildings The wall surface within 1 meter of the wall body shall be sprayed with termite control drugs; for the entrance of the cable trench 0.5 meters away from the outer wall of the ancient building and the cable trench inside the building, before the wall is laid and approved, Spray termite control drugs on the bottom, both sides and entrance of the cable trench; inject termite control drugs into the holes eaten by termites in the wooden door frame and wooden window frame, or adjacent to the wooden door frame and wooden window frame Drill 5 mm holes at a distance of 25 cm to squeeze out the termite control medicine, and then spray the wooden door frame and the wooden window frame with the termite control medicine.

Example 2

Raw material ratio and preparation of termite control preparation:

The raw materials in the termite control preparation were mixed according to the parts by mass described in Table 1 to obtain 4 groups of termite control preparations I to IV with different mixing ratios.

Table 1 The termite control preparations of different mixing ratios (mass parts)

group I II III IV Aconitum Aconitum Extract 2.3 3.2 3.6 4.5 Aconitum extract 1.2 1.8 1.8 3.2 pinellia extract 2.6 3.1 2.7 3.1 Rapeseed Extract 1.1 1.4 1.5 1.9 Juvenile Hormone Insecticides 2.5 2.9 2.9 3.9 imidacloprid 1.8 2.6 2.5 2.6 Fipronil 2.1 3.1 3.2 3.5 Rosin powder 1.5 1.7 1.6 2.3 stabilizer 0.1 0.2 0.2 0.5 Antioxidants 0.3 0.3 0.4 0.7

The preparation method of termite control preparation is carried out according to the following steps: step 1, stir Aconitum aconitum extract, Aconitum aconitum extract, pinellia extract, and Semen japonica extract in the ratio of Table 1 to obtain the first mixture; step 2, Mix and stir the juvenile hormone insecticide, imidacloprid and fipronil according to the ratio in Table 1 to obtain the second mixture; Step 3, add rosin powder, stabilizer and anti-corrosion agent after mixing the first mixture and the second mixture. The oxidizing agent is further stirred evenly to obtain the finished product.

The control effect of embodiment 3 termite control preparations to termites:

(1) Determination of the efficacy of termite control preparations on termites:

Inject 0.5 g of termite control agent into a section of wood channel eaten by termites, and place 30 healthy termites and the wood in an incubator under 28±1°C and dark conditions for rearing. Every 24 hours, observe and record the number of dead termites.

Table 2 The determination of the efficacy of termite control preparations I to IV on termites

As can be seen from the results in Table 2, termite control preparations I to IV all have a good killing effect on termites, and the peak time of termite death is after two, three and four days of treatment, and termite control preparation I causes all termites to die. The time required is about 6 days (144h). The termite control preparation I can cause the death of all termites in 5 days (120h), the termite control preparation IV can cause the death of all termites in 4 days (96h), and the termite control preparation III only needs 3 days. (72h) can make all termites die.

(2) Determination of the contact toxicity transmission of termite control agents to termites:

Connect the bottoms of the two glass or PVC cylinders A and B with glass tubes or hoses, put 60 healthy termites in cylinder A, and put 5 termites stuck to the powder in cylinder B, with pinholes Cover the cylinder of the test device with aluminum foil, and then move the test device into an incubator at 28±1°C in the dark. Every 24 hours, observe and record the number of dead termites.

Table 3 The determination of the contact toxicity transmission of termite control preparations I～IV to termites

It can be seen from the results in Table 3 that, utilizing the biological characteristics of termites, the poison-carrying termites transmit the virulence of the powder to other termite individuals, so that the individual termites that do not directly contact the powder also die, thereby killing the entire ant colony. As can be seen from Table 3, termites have the ability to transmit virulence to termite control preparations I～IV, and the minimum mortality rate of termites to termite control preparation I treatment group after 48h is 55%, and the time for all termites to die needs 6 days (72h); termites need 5 days (120h) to the death rate of termite control preparation II treatment group after 48h at 70%, and the time for all termites to die; 4 days (96h); termites to the termite control preparation IV treatment group had a mortality rate of 80% after 48h, and it took 5 days (120h) for all termites to die. It can be seen that the termites have a good ability to transfer the toxicity to the termite control preparations I to IV, and can be used for termite control.

(3) Typical cases of construction using termite control methods in ancient buildings:

Case 1: The termite control agent I was used to prevent termites in ancient buildings. After one year of on-site observation, no termite damage was found in the protected ancient buildings, which ensured the safety of ancient buildings and protected cultural heritage.

Case 2: Using termite control preparation IV, the method of this example was used to prevent termites in ancient buildings. After two and a half years of on-site observation, no termite damage has been found in the protected ancient buildings so far, and the cultural heritage has been protected.

Case 3: The method of this embodiment is used to prevent and control termites in ancient buildings by using termite control preparation III. After 3 years of on-site observation, no termite damage has been found in the protected ancient buildings so far, ensuring the safety of ancient buildings and protecting the cultural heritage.

Finally, it needs to be explained that the above description is only a preferred embodiment of the present invention. Under the inspiration of the present invention, those skilled in the art can make various similar representations without violating the purpose and claims of the present invention. The transformations all fall within the protection scope of the present invention.
