Method for preventing ergate of Coptotermes formosanus from alimentation

Abstract

The invention relates to a method for preventing a Coptotermes formosanus Shiraki ergate from feeding. The method is characterized in that: according to a total volume fraction equal to 100 percent, 77 to 78 percent of yellow mud powder and 22 to 23 percent of sodium hydroxide or potassium hydroxide solution are mixed to make pug with pH value of between 10.6 and 10.8; then, the object foodstuff for termite is completely wrapped by the pug. The method can effectively prevent a Coptotermes formosanus Shiraki ergate from eating the object wrapped inside the pug; therefore, the method can be used in the termite damage prevention of underground cable, and protects a buried cable and underground facilities made from PE or PVC from termite damage.

Description

A kind of method that prevents Coptotermes formosan worker ants from feeding technical field The invention relates to a method for preventing termites from eating, in particular to a method for preventing Taiwanese milk termites (Coptotermesformosanus Shiraki) workers from eating target food by using alkaline wet mud cake. Background technique Termites are the oldest social pests and are listed as one of the five major pests in the world by the International Insect Physiology and Ecology Research Center. The climate in South China is warm, the vegetation is diverse, the food is rich, the soil is moist, and most of the soil is weakly acidic, which is suitable for the reproduction of termites. Among them, the reproduction of Taiwan milk termites is the most common. , transportation facilities, etc. have caused serious harm, and collapse accidents caused by termites penetrating houses and other buildings have occurred from time to time. Taiwan milk termites will also feed on ...

For this reason, our country has adopted a variety of anti-termite measures for facilities such as communication and power cables buried underground. The most important one is the use of organophosphorus or organochlorine drug-type anti-termite cables, which can be used within a certain period of time. It is free from termite damage, but because the chemicals used are highly toxic and have a long residual period, they will cause potential pollution and damage to the ecological balance of the environment and water resources, and due to the aging of plastics and the slow release of drugs, this kind of cable will gradually lose Anti-termite effect

According to investigations, Guangzhou City once purchased 110KV ant-proof high-voltage cables from abroad and laid them underground, but the outer sheath was severely corroded by termites within three years of operation.

In addition, ecological control of termites is also used. For example, it is reported that a mixture of 1% to 10% quicklime and 90% to 99% yellow mud powder and a mixture of 5% quicklime and 95% fine furnace cinder are used to block black wing soil. Indoor tests where termites have lost their wings and reproduced ants, but the corresponding water content and pH range of the mixture are not indicated, so termites still cannot prevent termites from drilling through the mixture to eat the target food under the conditions of water and pH suitable for termites to survive
