RU57555U1 - DEVICE FOR CULTIVATION AND STERILIZATION OF A TOLFART FLY - Google Patents

Abstract

The invention relates to veterinary entomology, in particular to devices for the cultivation and sterilization of insects and can be used for sexual sterilization of a wolfart fly with gamma radiation. The technical result that can be obtained using the present invention is to reduce the population of Wohlfahrtia magnifica by mating sterile males with females, as a result of which the larvae do not develop and die, thus the natural population of flies is not replenished, but reduced to an economically insensible level, this method parasite control of insects does not harm the environment, it acts highly specifically and significantly reduces the economic costs of controlling parasites. A device for culturing and sterilizing a tungsten fly consists of a housing 1, inside of which a nutrient medium heater 2, an air humidifier 3, a gamma radiation source 4 equipped with a protective casing 5 and hatches 6 for supplying air, a nutrient medium for communication with the cage 7 are mounted.

Description

FIELD OF THE INVENTION

The invention relates to veterinary entomology, in particular to devices for the cultivation and sterilization of insects and can be used for sexual sterilization of a wolfart fly with gamma radiation.

State of the art

The “Device for irradiation” is known, containing a holder with radioactive sources located in the same plane, an object holder and a rotation mechanism of the holder, in order to improve the quality of irradiated objects by increasing the uniformity of radiation, it is equipped with an additional rotation mechanism for the object holder relative to its axis of symmetry (see RF patent No. 1082207 class 02 1 K 5/00).

A disadvantage of the known device is the complexity of the irradiation process in the case of pupae of a tungsten fly.

The well-known "Gamma-irradiation installation", comprising a working chamber with an extended flat irradiator, biological protection, a labyrinth transport line for delivering containers with irradiated objects to the working chamber from the unloading loading area and vice versa, the transport line is made in the form of a double closed loop in which the transition from the external to the internal and from the internal to the external, it is made at different levels, while in the working

external and internal sections of the circuit are placed on the same level on opposite sides of the irradiator and parallel to it, and the loading and unloading zone is located near the outermost section of the circuit that is most remote from the working chamber (see RF patent No. 2093911, class G 21 K 5/00 , publ. 10/20/1997).

A disadvantage of the known device is the inability to irradiate large numbers of pupae.

Closest to the proposed device is a "Device for culturing a tungsten fly", the known device includes a housing in which a medium heater, an air humidifier and hatches for supplying air, medium and communication with the cage are mounted. (See.with. USSR No. 1426520 class A 01 K 67/00). A disadvantage of the known device is the absence of an irradiating element, which makes it impossible to obtain sterile individuals tungsten fly.

Disclosure of invention

The technical result that can be obtained using the present invention is to reduce the population of Wohlfahrtia magnifica by mating sterile males with females, as a result of which the larvae do not develop and die, thus the natural population of flies is not replenished, but reduced to an economically insensible level, this method parasite control of insects does not harm the environment, it acts highly specifically and significantly reduces the economic costs of controlling parasites.

The technical result is achieved using a device for the cultivation and sterilization of tungsten flies containing a housing in which a medium heater is mounted, a humidifier

air source, gamma radiation source, protective cover and hatches for air supply, nutrient medium and communication with the cage.

Brief Description of the Drawings

The figure shows a General view of a device for the cultivation and sterilization of tungsten flies.

The implementation of the invention

A device for culturing and sterilizing a tungsten fly consists of a housing 1, inside of which a nutrient medium heater 2, an air humidifier 3, a gamma radiation source 4 equipped with a protective casing 5 and hatches 6 for supplying air, a nutrient medium for communication with the cage 7 are mounted.

A device for culturing and sterilizing a tungsten fly is operated as follows: larvae are obtained by laying them with females on a piece of fresh meat. After 30 hours, they are transferred through hatch 6 to heater 2. The larvae develop 5 days at the optimum temperature, humidity and air composition. Larvae fall on the sand of housing 1, where they pupate. 2 days before departure, the adult pupae are transferred to a protective casing 5, where they are treated with ionizing radiation. In the future, sterile imagoes are made, which fly into the cage 7.

The invention in comparison with the prototype and other technical solutions has the following advantages:

- a device for the cultivation and sterilization of tungsten flies allows you to fight insect parasites according to a method that does not harm the environment.

- This control system is highly specific and acts on a specific population.

- reduces the need for insecticides.

- extremely profitable economically.
