SU62932A1 - Device for the collection of barn mites and other insect pests - Google Patents

Description

in entomological and similar laboratories, research and development requires the selection and sorting of species of various kinds of insect pests, in particular, granary ticks. For this purpose, devices consisting of a chamber for the studied insects, a heating chamber, a migration channel and a mite collector are used.

The proposed device is distinguished by the fact that, in order to select a particular species of tick by otchivaning all other insects back, the migration channel, separated by a net from the chamber with the test material with insects, is located above this chamber and has a socket over it placed above the collector.

On fig. 1 is a front view of the device in section along AB in FIG. 2; in fig. 2 - plan view of the device; in fig. 3 - the same, side view (along arrow D in FIG. 1).

The test material containing mites, as well as other small insects, is placed in a tin mite box. Inside the latter there are a series of longitudinal partitions attached to the grid 2. The bottom terminal is heated by an electric lamp 3 placed in a closed heating chamber 4.

In order to direct heat from the electric lamp to the receiver, a reflector in the form of a Boonet mirror 5 was placed below the lamp in the heating chamber.

The required temperature in the chamber for the material under study is regulated by means of a thermostat 6 with a thermometer 7, the hatch of which is open out through the slit in the wall of the device.

When heated (up to T 50 °), the mites and other small insects begin to leave the mantra along its internal partitions and through the openings of the grid 2 enter the migration channel, equipped with a socket 8.

The migration channel is monitored all the time through a half-strengthened magnifying glass of ten tenfold magnification. Observing through a magnifier, the worker passes only a certain type into the socket 8

ticks or other insects; If unnecessary species appear, the worker presses them with a needle in the socket or sweeps them back into the junction box. In the case of enhanced migration of ticks and other insects, when it is not possible to observe a particular species, it works by gently tapping on the edge of the socket, flicking the ticks back into the tick, the catcher. Ticks, missed into the socket 8, freely creep over it, fall onto its edges, and from there into the funnel 10 of the collector. This funnel must be filled with a sterilized nutrient substrate, where the mites and other insects remain until the entire selection process is completed.

At the end of the work, the narrow opening of the bell 8 is closed with a rubber stopper; the socket after the mite has been removed is removed and after that the funnel 10 of the wiper with its nutritive substrate is removed. The latter, together with the tongs, goes to the destination.
