Description
Technical Field
The invention belongs to the technical field of rodent prevention and control, and particularly relates to bait and a throwing tool for monitoring density of a rodent by a gnawing method.
Background
The rat density measurement is a necessary means for knowing the number of pest rats, accurately putting poison baits and checking the killing effect. The main current methods for monitoring the density of the rat are a trapping method, a cage trapping method and a blotting method. But none of the capture methods can equally capture individuals of all species. In addition, due to the influence of environmental characteristics, climatic characteristics, individual position and species composition of an investigation region, the monitoring efficiency of different methods on different murine populations (communities) is greatly different. How to simply, quickly, stably and reliably obtain the accurate population (colony) number of the harmful rats is still the goal pursued by rat damage prevention and control workers.
The trapping method represents the relative number of rats in the investigation region in terms of trapping rate. Is the most common method for monitoring the wild and indoor rat conditions in China and even the world. The method has the advantages of being simple and easy to operate, being applicable to different environments, being capable of obtaining the mouse samples and further comparing the structural characteristics of the mouse populations or communities in different time and different places. But it has inherent disadvantages: (1) due to the trapping and killing, the method can generate great disturbance to the population or community; (2) the capture rate difference of different plots is large due to environmental heterogeneity; (3) the specification difference of the mousetrap, the sensitivity of different mouse species and/or different age groups of the mouse to the mousetrap, and the preference degree of the mouse for placing the bait; the clamping capture rate can be greatly different due to different operator operations, different cloth clamping methods (clamping distance, cloth clamping modes) and other factors; (4) the mousetrap can injure the operator and non-target animals by mistake.
Cage capture is a method in which the density of mice is calculated by cage capture rate or marker recapture. The method has the advantages that animals are not killed, disturbance to animal communities is small, dynamic characteristics of communities or populations can be objectively reflected, and investigation data are detailed and accurate. But the method has the difficulties of complicated investigation operation, labor and time waste, high technical requirements on the investigators and the like; another difficulty is how to accurately estimate the size of the population from the recapture data, requiring specific mathematical algorithms to estimate the density. Therefore, it is mainly used in the field of scientific research.
The blotting method is a general term for both the powder-smearing method and the gnawing method. The powder painting method can only be used in relatively flat places indoors. According to a certain principle, square powder printing blocks are arranged, when the mouse walks through the printing blocks, foot prints are left, and the number of the powder printing blocks with the foot prints is counted to calculate the relative density of the mouse. The powder method has no generality and transverse comparability of different places. The gnawing method is also called as a stealing-eating method, bait is thrown in an investigation region in a certain mode within a specified time, and the density of the rats is estimated according to the stealing-eating condition of the rats to the bait. The food gnawing method is simple and easy for production departments, has low technical requirements and can be used on a large scale. Because the method does not disturb the murine community (population), the scheme is properly designed and can accurately reflect the relative density of the murine.
At present, food blocks which are suitable for local conditions are used as baits in various places in China when a gnawing method is used, and no tool with a uniform specification exists for loading the baits. Due to the differences of palatability and attraction of the bait, the accuracy of the bait is greatly influenced. On the other hand, different self-made baits are used in different places at present, and the density of the rats obtained at different times in different regions is not comparable.
Adopts uniform baits with good palatability and uniform baiting tools. The above inherent disadvantages in the use of current gnawing methods can be overcome. The mouse density can be conveniently and accurately monitored, and meanwhile, the mouse density can be compared among different time and different places. And further provides detailed data for the prediction and forecast of the number of the rats and the objective evaluation of the deratization effect. The practicability, the scientificity and the social demand are all great.
