Description

Technical Field

[0001] The utility model relates to the technical field of insect collection, in particular to a novel monitoring and collection device for free fleas in nest holes. Background Art

[0002] Plague is a highly contagious disease caused by Yersinia pestis. Its natural hosts in my country are marmots, yellow mice, gerbils and house mice. Arthropods such as fleas, ticks and mites are its transmission vectors, of which fleas are the most important transmission vectors. Fleas, ticks and mites on the surface of rodents, caves, natural foci of caves and certain indoor and outdoor environments are small and agile. They have a very close relationship with humans and animals. They are important transmission vectors and storage hosts for many diseases such as bacterial infections. Some fleas spread various serious epidemic diseases by biting and sucking blood, and the most important one is the plague. In order to prevent the occurrence and spread of plague and other epidemics, the world's disease prevention and control departments, border port customs quarantine agencies, etc. need to collect a large number of free fleas, ticks and mites from nests and caves for classification and identification, and then use serology and molecular biology to identify them. The method is used to detect plague and other pathogens, including nest fleas, cave dry fleas, and indoor free fleas or some rat fleas, etc., which are used to monitor and calculate the flea density and infection situation, and are used to predict and warn of epidemics. Collecting fleas, ticks, and mites using this method can even achieve twice the result with half the effort compared to mouse catching detection. At present, research on flea collection generally involves scraping the soil on the inner wall of animal caves or stirring the soil by wrapping towels around soft objects to complete the collection of fleas shallowly attached to the inner wall of the nest. This type of collected fleas not only causes certain damage to the activity of the fleas themselves, but also exposes them to the outer surface of the collection structure, making them easily detached during extraction, resulting in a reduction in number. It also poses certain safety hazards to collectors, making it impossible to achieve convenient and safe collection operations, affecting collection efficiency. Utility Model Content
