Definitions
- Termite breeding device and assembly The present invention relates to the field of termite breeding.
- termites is meant the Isoptera ⁇ Termitoidae / Isoptera).
- the present invention is in particular applicable to all so-called “lower” termites, that is to say having a social determination allowing the production of secondary reproducers or neotenics from larvae or workers or pseudergates.
- This includes Mastotermitidae, Termopsidae, Hodotermitidae, Kalotermitidae, Rhinotermitidae, Serritermitidae.
- termites to convert and recover residues rich in lignocellulose, particularly from agro-industry, is an innovative and promising approach. Indeed, termites demonstrate great digestive capacities, including vis-à-vis polymers that are difficult to degrade such as lignin.
- Japanese utility model JP3199484(U) describes a termite viewing framework.
- This frame has transparent side walls between which are placed sand and pieces or shavings of wood of various kinds.
- a hole formed in the frame allows the introduction of termites and water. This makes it possible to observe the behavior of termites with respect to the different species of wood placed in the frame.
- this laboratory device suitable for observing the behavior of termites, is in no way designed or suitable for breeding termites.
- US2151589 describes a container suitable for receiving termites and allowing their observation.
- This container essentially consists of a transparent tube in which is placed a strip of cellulosic material in contact with one wall of the tube. This container is suitable for observing a termite colony, but not for breeding on a significant scale.
- the Chinese utility model CN211153414(U) describes an insect rearing device. This device is intended for breeding termites in the laboratory, and comprises several cells, each cell comprising a square box and a cavity, and a closing curtain that ensures no termites escape. However, this system is only suitable for laboratory rearing, and can be greatly improved.
- the Chinese utility model CN203985616(U) finally presents an incubation device comprising groups of nests of termites (namely Reticulitermes) and allowing their visualization.
- the device has the shape of a box divided by transverse diaphragms into a plurality of supply compartments. A cell is formed in the middle of each feeding compartment with water retaining material, and a piece of wood is placed in the cell.
- this device does not correctly respect the natural social organization of termites, and is not suitable for large-scale automated breeding.
- isoptera (termites) concentrate in small places and move in networks of galleries that they build themselves. same.
- termites must interact with each other to provide food for castes unable to feed themselves (soldiers, young larvae, breeders) and more generally to ensure the cohesion of the colony.
- the invention thus aims to propose a termite breeding device making it possible to respond to all or part of the problems set out above.
- the invention relates to a termite breeding device comprising a tank containing a bed of a substrate suitable for the life of termites and a set of frames, a lignocellulosic material being placed in each frame.
- the tray forms or contains a frame support structure, said support structure maintaining the frames vertically and removably vis-à-vis the tray.
- a lower edge of each frame thus rests on the bed of substrate.
- the lower edge has one or more openings configured to allow the passage of at least some termites between the bed of substrate and the interior of the frame.
- the frames are juxtaposed side by side substantially parallel, the lignocellulosic material of each frame being separated from the lignocellulosic material of the adjacent frame(s) by at least one side wall.
- the device thus formed also called “elementary breeding unit” reproduces the natural habitat of termites (in particular termites of the Termopsidae family, in particular Hodotermopsis sjoestedti, or Rhinotermitidae, in particular Reticulitermes flavipes,).
- termites in particular termites of the Termopsidae family, in particular Hodotermopsis sjoestedti, or Rhinotermitidae, in particular Reticulitermes flavipes,.
- the arrangement of the frames on a bed of substrate reproduces the natural environment of these termites.
- the configuration of the frames containing a lignocellulosic material such as wood, in the form of pieces, shavings, compacted powder, sawdust, paste, or, in a non-exhaustive manner, straw, bagasse, cardboard, paper, etc
- a lignocellulosic material such as wood, in the form of pieces, shavings, compacted powder, sawdust, paste, or, in a non-exhaustive manner, straw, bagasse, cardboard, paper, etc
- the frames thus arranged allow easy harvesting of the termites present in said frames, and more generally of the “outputs” of the device (termites, excrement, and nests).
- the removal of a frame (or a plurality of frames) also allows its easy transfer to another similar rearing device, in order to create a new colony of termites.
- Each frame may have two side walls.
- Each side wall may be transparent, for example formed from transparent polycarbonate.
- the side walls have a role of maintaining the lignocellulosic material in the frame.
- the material can be held in the frame without sidewalls to hold it when removing the frames from the bin.
- the walls are transparent, they allow direct observation of the contents of the frame. This observation can be useful during breeding, that is to say during the development of the termite mound in the frame, but also during the harvesting of the contents of the frame, for example to know if the moment of carrying out this harvest arrived.
- the removal of the frames does not lead to the destruction of the galleries present in the frame and in the substrate, the disturbances are limited and allow a characterization over time of the evolution of the colony, after successive observations of the said frames.
- the configuration of the breeding device proposed according to the present invention thus minimizes the disturbances on the termite mound and respects its social organization.
- Each side wall may have holes sized to allow the passage of at least some termites.
- the device may comprise a system allowing the closing or the release of all or part of the openings of the lower edge of the frame which rests on the bed of substrate.
- the size of the orifices can thus prevent the circulation of certain castes of termites from one frame to another.
- a smaller size than the head of a soldier or reproductive termite allows for one (or more) frames that can only be colonized by worker termites. This can be interesting when harvesting frames, or to facilitate "cuttings" by the appearance of secondary reproducers (neotenic).
- Cuttings or layering thus consists in isolating part of the colony of termites (of certain castes) in order to move it to another rearing device, which is empty.
- the absence of pheromonal signals emitted by the reproducers makes it possible to induce a differentiation of pseudergates into neotenics (secondary reproducer) and thus to start a new colony.
- the system for closing the openings in the lower part of the frame allows access to the interior of the frame from the substrate or not. It can complement the holes present in the side walls to allow passage in a frame only for certain termites. Indeed, if the edge (i.e. of one of the thin edges) of the frame which rests on the substrate has its openings closed, the only remaining passages allowing termites to access the interior of the frame are the calibrated holes in the side walls.
- the sealing system can also be used to selectively seal certain openings, for example to leave free only openings allowing the passage of only certain termites, for example of desired castes.
- This closing and release system can for example take the form of a ruler which can be put in position or removed from the edge of the frame, or of a ruler which can be translated to open or close these openings.
- the ruler can therefore comprise corresponding openings, which are placed in correspondence (facing) or not vis-à-vis the openings present in the edge of the frame.
- This closure and release system can alternatively be formed by a removable lower upright that can be added or removed from the rest of the frame.
- Each frame may comprise on its edge opposite to the lower edge which rests on the bed of substrate, a ventilation structure configured so as to allow the passage of air but not the passage of termites.
- the ventilation structure may have holes with a maximum diameter of 0.7mm or slots with a maximum width of 0.7mm. This structure also allows the supply of water.
- Air ventilation is thus ensured in the upper part of the frame, when it is in place in the rearing device.
- the escape of termites, especially from the pseudergate stage, can be avoided. Openings that do not allow a circle of more than 0.7mm to be inscribed on their surface, that is to say, for example, round holes of 0.7mm maximum, or slots 0.7mm wide at the maximum, allow this.
- the lignocellulosic material may comprise lignocellulosic residues from industry.
- the residues are thus converted by digestion by the termites.
- the residues concerned may thus be co-products or waste rich in lignocellulose (or simply cellulose), derived from wood or plant materials, from the food, agricultural, forestry, processing industries for starch, stationery, etc Examples include woody residues from forestry, sawdust, bagasse, straw, waste paper or cardboard, etc.)
- the substrate can advantageously mainly contain sand or mineral earth.
- the bed of substrate may in particular have a thickness of between 1 cm and 8 cm.
- the objective of the substrate is to reproduce a soil in which the termites can form galleries, move, and live.
- the bed of substrate is therefore advantageously essentially made up of a mineral, non-nutritive material. Fine sand is suitable for forming this bed of substrate.
- a nutritive material for termites in particular in the form of a powder, such as a wood powder, (for example a very fine wood powder, with a grain size of the order of 300 microns) can be integrated into the substrate, by small amount.
- Each frame can have:
- the tray can be substantially rectangular parallelepipedic and have:
- the frames thus dimensioned are easily manipulated, manually or using automated systems. They are suitable for containing easily available wood particles (powder, shavings). Their dimensions can in particular allow the maintenance of the particles of compacted wood, and/or of another lignocellulosic material, without any particular means of maintenance.
- the spacing between the side walls also allows termites to move. Ideally this spacing is less than twice the diameter of a gallery in order to be able to observe the termites.
- the invention also relates to an assembly for breeding termites comprising several termite breeding devices as previously described, said assembly comprising a vertical structure suitable for receiving said breeding devices in the form of shelves or racks. The vertical structure can be organized in parallel shelves, forming aisles between them.
- the assembly may include an aeraulic system suitable for supplying air to each termite breeding device and for extracting the gases from said assembly.
- the breeding device can thus be used in large numbers to form a large-scale breeding. Breeding is advantageously “verticalized”, that is to say that it uses storage structures at height for breeding devices. The surface area used for breeding is reduced, and access to the various breeding devices is simplified. Similarly, the air and water supply to the rearing devices is simplified. Maintaining adequate rearing conditions (particularly in terms of temperature, humidity, and/or CO2 content, etc.) can be effectively achieved.

- figure 10 details, according to a schematic view in three dimensions, the assembly of figure 9,
- FIG. 1 represents, according to a schematic three-dimensional view, a termite breeding device 1 in accordance with one embodiment of the invention.
- This device comprises a tank 2.
- the tank 2 contains a bed of substrate 3.
- the bed of substrate constitutes a medium, preferably essentially mineral, allowing termites to dig galleries there and to live there.
- the substrate is preferably non-nutritive and non-putrescible, in particular mineral, and is advantageously made up of fine particles allowing the termites to move and in particular to "manipulate" it with their mandibles and use it to shape galleries.
- This substrate can consist of sand, vermiculite, perlite, etc.
- Fontainebleau sand or Fontainebleau micro-sand
- Fontainebleau sand is fine-grained sand (grain diameter less than 350 pm), extra-siliceous (97% to 99% silica) and round to sub-angular grains.
- the substrate bed may for example have a bed height h of 1 cm to 8 cm.
- a bed height h of 3 cm to 5 cm can in particular be used.
- the substrate can be enriched with a material digestible by the termites, for example a wood powder.
- the substrate bed is moistened so that it has a maximum humidity of 25%.
- the rearing device 1 further comprises a frame assembly 4.
- Each frame 4 is an element, generally rectangular parallelepiped, of small thickness E compared to its width I and its length L.
- Each frame contains a lignocellulosic (eg lignocellulosic) material forming a food compound suitable for termites.
- This compound may include compacted pieces of wood and/or compacted wood powder.
- the wood used can be of any species suitable for termite feeding. Common species such as birch, poplar, and pine, and more generally wood species tender, can be used. The wood must not have been chemically treated.
- This food compound can be enriched by lignocellulosic residues from industry, which will thus be treated, converted, by their digestion by termites.
- the lignocellulosic material is moistened to form a paste which textures the feed blocks thus formed in the frames 4.
- Preservatives can be added to the lignocellulosic material, to prevent the appearance of mould.
- potassium sorbate can be added at a concentration of 0.3% without negative effect on the colony.
- the frames 4 are kept vertical, their lower edge 6 resting on the bed of substrate 3. By resting, it is understood that the lower edge 6 is in contact with the bed of substrate, and possibly slightly sunk into it.
- the lower edge 6 is equipped with one or more openings allowing the passage of at least certain termites.
- certain termites it is meant termites of dimensions smaller than a predefined dimension, and which correspond to one or more castes of termites.
- the lower edge 6 is, in the preferred example shown, one of the edges located in the length L of the frame.
- the frame may comprise in the upper part, that is to say at the level of its upper edge 7, which is the edge opposite the lower edge 6, a ventilation structure 8.
- the ventilation structure allows the exchange of air between the inside of the frame 4 and the outside, and can have other functions detailed with reference to Figure 6.
- the frames 4 are juxtaposed side by side. They are thus erected substantially parallel in tray 2 of rearing device 1.
- At least one so-called side wall is interposed between the lignocellulosic material contained in a frame and the lignocellulosic material of each adjacent frame.
- the frames can themselves be devoid of side walls, like the frame of FIG. 2. This means that the dimensions of the frame and the nature of the lignocellulosic material allow said lignocellulosic material to remain in the frame without additional holding means.
- a compacted and moist wood powder has a satisfactory hold, allowing the handling of the frames and their harvesting without the lignocellulosic material falling from the frame.
- each frame 4 has two side walls 9.
- the side walls 9 make it possible in particular to guarantee the maintenance of the lignocellulosic material in the frame 4.
- These side walls 9 are advantageously transparent, in order to allow observation. termites and the part of the colony present in frame 4.
- the side walls 9 can for example be made of transparent plastic, in particular transparent polycarbonate (polymethyl methacrylate generally called plexiglass or plexiglass (registered trademark)).
- Figure 4 shows a frame 4 identical to that of Figure 3.
- the frame 4 is shown seen from below (with its lower edge 6 in the foreground) .
- Figure 4 thus allows a good view of the two side walls 9 of the frame 4, as well as of the lignocellulosic material 5 placed between the two side walls 9.
- the lower edge 6 of the frame has a wide opening (the edge is almost entirely open) which allows the circulation of termites from the bed of substrate 3 towards the lignocellulosic material of the frame, and vice versa.
- the side walls 9 have orifices 10 sized to allow the passage of at least some termites.
- the orifices 10 are, in the example represented, round orifices which cross the side wall 9. Their diameter is calibrated. The diameter of the orifices 10 can in particular prevent the circulation of certain castes of termites from one frame to another. A size smaller than that of the head of a soldier or of a breeder allows, for example, frames whose side walls have such orifices to be colonized only by workers.
- This configuration therefore makes it possible to harvest frames easily. It allows, if necessary, the creation of new colonies. It also makes it easy to renew food for the colony. More generally, this configuration allows a sorting of termites concomitant with their harvest.
- the side walls can, optionally, be removably mounted on the frame 4.
- Different removable attachment configurations are possible.
- the side walls 9 can be housed in grooves formed in the side uprights 11 of the frame 4 and held by stops fixed by screws in said uprights.
- the stops can, if necessary, also be used to fix the shutter rule of the opening formed in the lower edge 6.
- the frames presented here by way of example have the following dimensional characteristics: a length L of 16 cm , a width I of 10.4cm, and a thickness of 2cm. Obviously other dimensions are possible, as long as they allow easy handling of the frame, and the development of the colony of termites in the frame.
- the interior volume of the frames is in particular dimensioned so as to be sufficient to contain a large population of termites and to allow the development of secondary reproductive termites.
- FIG. 5 represents, according to a schematic view in three dimensions, a breeding device in accordance with one embodiment of the invention.
- tray 2 of the device is transparent, and the substrate bed has been omitted.
- Figure 5 makes it possible in particular to visualize the maintenance of the frames 4 parallel to each other in the tray 2.
- the tray 2 comprises support structures 13 shaped to receive support from the lateral extensions 14 of the frame 4.
- the support of the lateral extensions 14 of the frame 4 on the support structures 13 maintains the lower edge 6 of the frame 4 at a distance from the bottom 15 of the tray 2.
- Support structures 13 are also visible in FIG. shows the frame of Figures 3 and 4 installed in a tray 2 to form a breeding device according to one embodiment of the invention.
- the support structures 13 of the example shown are formed of two longitudinal bars carrying cleats 16 which delimit the reception position of the frames 4. Of course, many other support structures are possible.
- the support must in particular be adapted to the configuration of the frames 4 used, and allow the maintenance of the vertical frames in the tray 2, at a distance from the bottom 15 of the tray 2.
- FIG. 6 also illustrates an example of a ventilation structure 8.
- the ventilation structure 8 is formed in an upper upright 17 of the frame 4.
- the primary function of the ventilation structure is to allow gas exchange between the interior of the frame (containing lignocellulosic material) and the outside of the frame.
- the ventilation structure 8 comprises, in the example shown here, ducts of square section with a side of 0.7 mm (or slightly less). This relevant dimension of 0.7 mm (side for square holes as in the present example, diameter for circular holes, width for slot-shaped holes) allows the realization of these three functions.
- FIG. 7 represents, according to a schematic view in three dimensions, an example of shelving that can be used to form an assembly for the breeding of termites in accordance with another aspect of the invention.
- the assembly comprises a vertical structure 18 in the form of a set of shelves 19 suitable for receiving breeding devices 1 in accordance with the present invention.
- the termite breeding set may have many sets of shelves (or other vertical structures). These structures can be organized in parallel shelves.
- the organization in shelving allows the use of automated systems for the placement and removal of rearing devices on the shelves (or on any other reception structure).
- An a somehowlic system allows the supply of air in each of the rearing devices.
- FIG. 9 An example of an assembly comprising such an aeraulic system is shown in FIG. 9.
- the air supply can be achieved by establishing an air flow between the shelves 20 and through them, / or through ducts provided directly in the vertical structures 18 for receiving the breeding devices.
- the aeraulic system comprises a supply duct 21.
- the supply duct 21 introduces air, advantageously having a temperature around 26° C. and advantageously comprising around 80% humidity.
- the a somehowlic system comprises a recovery duct 22.
- Control means 23 of the a somehowlic system allow the control thereof.
- the rearing unit and correspondingly the aeraulic system, can be modular.
- several vertical structures 18 can be joined together to form said assembly.
- the supply duct and the recovery duct 22 can be formed from as many butted portions of ducts as there are vertical structures 18 in the whole.
- the a (2015)lic system comprises, in the example shown, an air supply column 24 and a gas recovery column 25 in each vertical structure 18.
- the air coming from the supply duct 21 is distributed in each of the air supply columns 24.
- the air supply column 24 allows the distribution of air at the level of each shelf 19 and in each of the devices breeding 1 of a vertical structure 18.
- the gas recovery column 25 allows the extraction of the air (and if necessary other gases produced by the termites) from each of the breeding devices of a vertical structure 18.
- the gases from the various air recovery columns are collected in the recovery duct 22.
- Air circulation in termite breeding, at the level of each breeding device, is important. It allows the temperature to be maintained around a desired setpoint temperature.
- the temperature is ideally at least 25°C, for example 26°C.
- the tray 2 has two internal walls 26, 27.
- the first internal wall 26 delimits a first volume 28 for the air inlet into the tray 2.
- the first volume 28 is separated from the substrate present in tray 2 by a first floor 29.
- the first floor 29 has holes allowing the passage of air but preventing the passage of termites.
- the second side wall 27 delimits a second volume 30 intended for the extraction of air (and other gases) from the device.
- the second volume 30 is separated from the substrate present in the tray 2 by a second floor 31.
- the second floor 31 comprises holes allowing the passage of gases but preventing the passage of termites.
- Relative humidity must also be controlled and controlled, ideally around 80%. This involves controlling the humidity of the air brought into the farm, but also through a water supply system.
- Water can be supplied via a system in which a central pipe distributes water to the various shelves. This water then flows naturally into the grooves (visible in FIG. 7) provided for this purpose in said shelves.
- the grooves are positioned so that the water coming out of them falls directly on the frames below. The water enters each frame via its upper edge 7, through the ventilation structure 8 of the frame.
- water can be supplied using a water spray system.
- a supply of water can thus be ensured by a spraying system.
- Its operating rhythm can be predetermined (for example a operation for 10 seconds every hour) and/or controlled by a control aimed at correcting the measured humidity.
- the affylic system allows the collection of gases from the rearing devices, with a view to their recovery.
- the methane produced by termites can thus be recovered.
- This termite lives in tropical areas of Asia. It belongs to the so-called "lower” termites of the Termopsidae family, thus containing protozoa in its microbiota and is capable of forming numerous secondary reproducers to increase the size of its colony. Under natural conditions, colonies can be quite crowded, reticulated in several nests, located in damp, rotting pieces of wood. The nest type is simple with no hard construction or specialized chambers.
- the reproductives mainly secondary, also called neotenic
- Stage 4-6 larvae are able to develop functional genitalia to become neotenous. All these characteristics, which testify to the simplicity of housing and the flexibility of the social organization of this termite, make Hodotermopsis sjostedti a termite suitable for breeding in devices and in a set as proposed in the present invention.
- the invention thus developed makes it possible to propose a breeding device whose design makes it possible to combine several advantages in the context of termite breeding.
- this device makes it possible to imitate the natural living conditions of termites by optimizing the environmental parameters (temperature, humidity) and by respecting the general structure of a natural nest (comprising a piece of wood with access to the ground).
- the proposed device facilitates the removal of termites from the breeding, in their environment, without causing significant disturbance for the rest of the colony.
- the use of removable frames provides a simple and effective technical solution for termite harvesting and more generally for colony management. This makes it possible in particular to adapt the breeding to the expansion of the colony, for example by replacing certain frames or by adding new frames.
- the configuration proposed in the invention makes it possible to modulate the structure of the termite colony by placing spacers (side walls) capable of filtering out certain castes of termites. This makes it possible in particular to give access to certain frames only to certain castes of termites. This can be used to create new colonies from these frames where the termites are sorted. Finally, some frames can be removed from a rearing device in order to remove certain elements likely to be affected by diseases or parasites.
- a farm made up of multiple breeding devices offers great modularity and offers advantages in terms of population monitoring and collection of data relating to breeding.
- the breeding configuration proposed in the invention thus makes it possible to sample the termites while limiting the disturbances on the colony.
- the use of frames allows in particular to access the termites without destroying the galleries. For example, it is possible to quantify the size of a colony by a capture-recapture method, or to identify the presence of spawners.
- the configuration also allows a progressive modification (or not) of the termite diet, in particular in order to integrate new types of industrial residues to be treated in the diet of certain termite colonies.
