The invention discloses a field capturing, short-term storing and feeding device for blood sucking midges and a using method thereof. The device is composed of a living body maintaining pipe, a sealing cover and a base. The living body maintaining tube is placed on the base; and a sealing cover is arranged at the top of the living body maintaining tube. The use method comprises the following steps: capturing living blood sucking midges in the field by utilizing the capturing state of the device; the device is converted into a feeding state, that is, a rubber plug fixed with an insect inlet unit and an air suction unit is removed, and a threaded semi-sealing cover with a feeding filter screen is installed; nutrient solution is provided for the gnat in the living body maintaining pipe through the feeding filter screen. The field catching, short-term storage and feeding integrated device overcomes the defects that an existing blood sucking midge collecting device cannot give consideration to the high catching rate, the high survival rate and the short-term storage and feeding function, and is simple in structure, convenient and fast to operate and capable of remarkably improving the survival rate of gnat from the catching stage to the laboratory stage.

The utility model discloses a tick in-vitro subculture device, which is characterized in that a hanging basket is driven by rotating an operating platform to simulate the blood flow of a host, a heating sheet, a heat conductor and a temperature controller are combined to maintain the temperature of feeding liquid, and a tick accommodating area and a feeding liquid area are separated by a biological membrane, so that the in-vitro simulation of a natural blood sucking state of ticks is realized. The device is detachable in structure and easy and convenient to operate, and the success rate of in-vitro subculture of the ticks is remarkably increased.

The application belongs to the technical field of tick feeding, and particularly relates to a double-control-temperature tick in-vitro membrane feeding system, which comprises a blood bin used for storing blood sources and having a composite film as a bottom surface; a tick breeding chamber used for accommodating ticks and installed at the bottom of the blood bin, wherein the tick breeding chamber covers the composite film; a double-control-temperature system comprising a heating module and a temperature sensor installed at the side of the blood bin, and a heating module and a temperature sensor inside the tick breeding chamber, wherein the double-control-temperature system adjusts the temperature difference between the blood source in the blood bin and the environment temperature in the tick breeding chamber to be 10 DEG - 12 DEG; and a constant-humidity spraying device connected to the tick breeding chamber and used for adjusting the humidity of the environment in the tick breeding chamber. The application meets the temperature difference between two sides of membrane feeding and humidity adjustment, simulates a real environment, and utilizes gravity to simulate a host blood pressure difference, thereby facilitating tick blood sucking.

The invention discloses a fixed tick feeding observation device. The fixed tick feeding observation device comprises an observation cylinder, a feeding seat and a fixed seat, a blood supply assembly is arranged in the feeding seat and comprises a capillary channel and a skin simulation slide glass arranged in the middle of the capillary channel, and the slide glass is of a multi-layer structure with an artificial membrane and a bionic skin matrix wrapping a capillary and can highly simulate real skin. Double temperature control is achieved through the water bath heating base and the heat preservation pad, the peristaltic pump is matched to drive blood to flow in microvessels, and dynamic blood supply is provided. The device integrates a micro pH sensor, an oxygen sensor and a microelectrode array, and can monitor the microenvironment change of a blood suction point in real time. And an adjustable observation mirror is arranged on the observation cylinder, so that multi-angle observation is facilitated. According to the invention, the problems of poor biomimetic property and insufficient monitoring capability in the prior art are solved, and refined observation and multi-parameter real-time monitoring of blood sucking behaviors of ticks under a highly bionic condition are realized.
