A casing bait that can trap and kill termites

Abstract

The invention relates to enteric-coated bait capable of trapping termites, which is prepared from the following raw materials: 0.0015-0.015% of nitenpyram and 99.9985-99.985% of pine sawdust or eucalyptus sawdust (20-80 meshes), and is prepared by the following steps: mixing raw materials, producing cylindrical bait by a forming machine, coating with cellulose casing of the corresponding size, naturally air-drying, and making into termite enteric-coated bait with the two ends open. The termite enteric-coated bait disclosed by the invention is generally arranged at mud cover, mud line and termite channels, inside or around swarming exit holes with termite activity to effectively monitor and trap dike termites, park termites and underground termites around houses and buildings. Nitenpyram used in the enteric-coated bait is efficient, low in toxicity, and environment-friendly. The bait does not contain starch-like substances, so as not to be easy for molding. The cellulose casing is used to protect bait shape, stop rainwater from penetration and reduce medicament loss. The two ends are open to facilitate feeding of termites. The enteric-coated bait disclosed by the invention has a good control effect, is simple in operation and environment-friendly, and has good generalization prospect.

Description

Technical field [0001] The invention relates to an enteric-coated bait capable of attracting and killing termites. Background technique [0002] Termites are one of the five major pests in the world. They can seriously harm housing construction, water conservancy projects, garden trees, underground cables, and agricultural and forestry crops. They are called "toothless tigers". The annual direct economic loss caused by termites worldwide amounts to 40 billion U.S. dollars, and the annual economic loss caused by termite damage in my country is also 10 billion RMB. Therefore, the prevention and control of termites is highly valued by domestic and foreign workers. As people pay more and more attention to environmental pollution and physical health, many highly toxic and highly polluting termite agents before the implementation of the Stockholm Convention on Persistent Organic Pollutants ("POPs") have been banned, such as chlordane and chlordane. Antling. The development and promot...

Problems solved by technology

However, the above two termite baits have the following defects: 1. Fipronil is highly toxic to aquatic organisms and has been banned from being used in field crop pest control; 2. Hexaflumuron belongs to insect growth regulators and is environmentally safe. , but the lethal time for termites is too long, which indirectly prolongs the termite damage cycle; 3. The termite bait contains a large amount of starch binder, which is easy to cause the bait to become moldy in a humid environment, affecting the termites to eat the bait, and shortening the termite life cycle. The duration of the bait ultimately reduces the termite control effect of the bait; 4. The termite bait lacks packaging, and the bait is easily lost in a humid environment, causing environmental pollution and poisoning aquatic organisms
