Abstract

A device for inhibiting the proliferation of insects, in particular mosquitoes, includes a container (1) for containing a liquid, and a filtering surface (40) which can be placed in two alternative operating positions with respect to the surface of the liquid (10; 20) : an immersed position, in which at least one portion (40a; 40b) of the filtering surface is immersed so as to allow insects to lay their eggs on the surface (10; 20) of the liquid, and a raised position, in which at least the one portion of filtering surface (40a; 40b) is raised above the surface (10; 20) of the liquid, thereby removing any larvae that were in the liquid between the surface (10; 20) thereof and the filtering surface (40a; 40b) when this was in the first position.

Description

A device for inhibiting the proliferation of insects, in particular mosquitoes
The present invention relates to a device for inhibiting the proliferation of insects, generally speaking of noxious insects with a predilection for humid environments, and in particular mosquitoes .
It is known that numerous species of noxious insects such as mosquitoes lay their eggs in places where sufficient stagnant water collects for the larvae to develop until their adult phase, such as ponds or puddles, or in barrels of water used for irrigating crops or in saucers used under plant pots to keep the soil moist .
It is also known that certain conventional methods used to keep away or eliminate mosquitoes, such as chemical insecticides for example, can themselves either be harmful to humans or damage the environment .
The object of the present invention is to provide a device for inhibiting the proliferation of insects, and in particular mosquitoes, which exploits the fact that the life cycle of the larvae requires liquid, thereby eliminating them before they turn into adult insects.
This object is achieved according to the invention by providing a device for inhibiting the proliferation of insects, and in particular mosquitoes, having the characteristics claimed in the Claims .
The characteristics and advantages of a device according to the invention for inhibiting the proliferation of insects will become apparent from the following detailed description of a few preferred but non-limitative embodiments, provided with reference to the appended drawings, in which:
Figure 1 is a sectioned view of a first embodiment of a device according to the invention for inhibiting the proliferation of insects;
Figure 2 is a schematic front elevation of a second embodiment of a device according to the invention, in a first operating position; and
Figure 3 is a side elevation of the device of Figure 2 , in a second operating position.
With reference to Figure 1, a device for inhibiting the proliferation of insects includes an open-top container 1 for holding a liquid up to a predetermined level, thereby simulating an attractive environment for mosquitoes to lay their eggs. The liquid is preferably one that attracts insects, such as one containing organic matter.
The container 1 has a bottom 2 folded so as to form two base surfaces 2a and 2b, reciprocally connected by a curved portion 2c. A partition 3 substantially forms two chambers 4a and 4b within the container 1, which are in fluid communication with each other beneath the filtering surface 40. The conformation of the bottom 2 makes it possible to alternatively tilt the container 1 in two different stable positions: a first position, corresponding to that illustrated in Figure 1, in which the base surface 2a rests directly on the ground T while the base 2b is raised off it, and a second position, not shown, in which the base 2b rests directly on the ground T while the base 2a is raised from it . In the first position, the mass of liquid arranges itself in the container 1 so that its free surface 10 is parallel to the base surface 2a. In the second position, this liquid mass arranges itself in the container 1 so that its free surface 20, indicated in broken outline in Figure 1, is parallel to the base surface 2b. The container 1 can be tilted by hand, by means of a lever 30 secured to the container 1, for example. On the side walls of the container 1, at least one overflow aperture 31 is also formed for each chamber 4a, 4b, in order to define the maximum level of the water free surface.
In a variant which is not illustrated, the lever 30 can be connected to an automatic movement device arranged to tilt the container periodically between its two stable positions .
A filtering surface 40 is also fitted to the container 1, for example, a grille having a mesh size fine enough to prevent the larvae at a certain stage of growth from passing through. The holes through the filtering surface 40 preferably have a size between 0.3 and 2mm, in dependence on the species of mosquito. The surface 40 includes two flat portions 40a and 40b, reciprocally connected at an angle and arranged in the container 1 in such a way that, when the base surface 2a rests on the ground, the entire portion 40b lies above the free surface 10 of the liquid, while the portion 40 is immersed therein, and that, when the base 2b rests on the ground, the entire portion 40a lies above the free surface 20 of the liquid while the portion 40b is immersed therein.
The partition 3 ensures that liquid does not overflow from the chamber 4a to the chamber 4b, or vice-versa, flowing over Attracted by the amount of liquid in the container 1 (in the position illustrated in Figure 1) , mosquitoes lay their eggs on the free surface 10 of this liquid, in the chamber 4a. After a few days, the eggs hatch into larvae which float in the stagnant liquid and feed on it, keeping near the surface 10 of the water so they can breathe.
By tilting the container 1 into the position in which the base surface 2b rests on the ground, the portion of filtering surface 40a is raised above the free surface 20 of the liquid, trapping all the larvae that had been living therein, between the free surface 10 and the portion 40a of filtering surface, out of the liquid.
In this way, once deprived of the liquid, the larvae quickly die. The smaller larvae, which may have managed to slip through the filtering surface, soon grow too big to pass through it and also die fairly rapidly, trapped beneath the filter. The larvae trapped in this area attract other mosquitoes, which also lay their eggs in the container.
New insects now have access to the free surface 20 of the water in the chamber 4b and the operation is repeated in reverse, thus not requiring a detailed description.
By tilting the container 1, it is thus possible to alternate the two flat portions 40a, 40b of the filtering surface 40 between two operating positions, one above and one beneath the free surface of the water, thereby removing the larvae from the liquid and killing them before they can develop into adult mosquitoes . Figures 2 and 3 illustrate an alternative embodiment of the device for inhibiting the proliferation of insects . Elements which correspond to those of the embodiment of Figure 1 have been given the same reference numbers . The present embodiment differs from the first in that the filtering surface 40 is movable with respect to a fixed container 1 and therefore also with respect to the mass of liquid, which does not move with respect to the container 1.
By means of an electric motor 50, which operates pulleys 51 via belts 52, the flat filtering surface 40 can selectively occupy a raised position above the free surface 10 of the liquid, as shown in Figure 2, or an immersed position close to the bottom 2 of the container 1, as shown in Figure 3. The pulleys 51 raise or lower the filtering surface 40 by means of cables 53.
The electric motor 50 is preferably powered by solar panels 60. It will be appreciated that instead of the electric motor 50, the filtering surface 40 could be moved by other, either automatic or manual means, such as a crank mechanism for example, able to transmit motion to the pulleys 51. In this case, the device according to the present invention would have to include releasable locking means, such as horizontal pins for example, in order to hold the filtering surface in its raised position for long enough for the mosquitoes trapped above it to die out of the water.
It is even more preferable for the container 1 to be connected to an auxiliary tank 70 which is able to top up by gravity the level of the surface 10 of the liquid. In this case as well, the overflow aperture 31 would continue to define a maximum level for the free surface of the water. The mechanism for moving the filtering surface can be operated periodically by an operator or can be controlled by a timer device (not shown) programmed to manage predetermined operating cycles .
As will be appreciated, the operating principle of the present embodiment is the same as that of the preceding one, except that the movements involved in immersing and raising the filtering surface 40 are obtained by directly moving this surface, while in the previous embodiment they were obtained by tilting the container, to which the filtering surface was fixed. It follows that the device shown in Figures 2 and 3 is better suited to cases requiring very large containers.1
It is clear that the invention is not limited to the embodiments described and illustrated here, which should be considered as examples of a device for inhibiting the proliferation of insects; the shape, dimensions and arrangement of parts, as well as the manufacturing and operating details of the invention may be modified according to any variants which may be deemed appropriate by experts in the art, without departing thereby from the scope of the invention, as claimed in the appended Claims.
