A. At least one active compound of the general formula
Description
5~2 Type V
The present invention relates to certain baits for ants based on certain phosphoric acid esters and addi-tives, to a process for their production and to their use for controlling ants.
It has already been disclosed that insecticides for controlling ants can be employed in a wide variety of formulations. Examples which may be mentioned are agenks for spraying, dusts, spray cans and baits. Since ants are frequently found in the neighbourhood of human and domestic animal living quarters, and must there be controlled, bait formulations are becoming increasingly important, both because of their comparatively slight danger to humans and domes~tic animals and also because of their general high degree of environmental acceptability.
The number of insecticidal active compounds which are suitable for use in a bait for ants is, however, very small, since the ants, which react very sensitively, mostly refuse to accept them. This is particularly true when the baits contain the artive compounds in high concentrations JO that the baits not only have a short activity, which lasts one or two days, but exhibit an activity and shelf-life extending over many months.
O,O-Diethylthionophosphoryl-~-oximinophenyl-acetonitrile (phoxim) and O,O-diethyl thionophosphoryl-~-oximino(2-chlorophenyl)acetonitrile (chlorphoxim) have been known for many years (compare German Patent Specification 1,238,902) as compounds with insecticidal and acaricidal activity which can be employed for con-trolling ants. These substances can be used in the form of agents for spraying and dusting.
Furthermore, it has been attempted to employ phoxim in the form of a bait formulation to control ants (compare "Toxicological and Biological Studies of Odorous House Ant, Tapinoma sessile" in Journ. of Econ. Ent., Le A 21 521 ~5~
volume 63, 1971-1973 (1970)). From this it emerged that complete control of ants can be achieved by baits which contain 0.05nO by weight of phoxim mixed with blackberry syrup or blackberry jam. However, it is a disadvantage that baits having such a low content of phoxim do not have a sufficiently long shelf-life for practical purposesO Analogous baits, in which the phoxim is present in a coneentration of 0.5~0 by weight to lUo by weight, do in fact exhibit a stability and duration of action which is sufficient for practical purposes, but they develop a repellent effect so that ants do not eat these baits. The use of baits which contain phoxim has thus not hitherto achieved the desired result in the control of ants.
An additional difficulty in the preparation o~
bait~ based on phoxim or chlorphoxim is that the active compounds are relatively sensitive to heat. Thus, the customary method of preparation, which consists of mixing the components and heating them in order to decrease the viscosity of the corresponding mixture and to make it easier to stir~ cannot be carried out.
The present invention now provides bai-ts for ants which consist of (a) at least one active compound nf the general formula C2H5 ~ ~ S / CN
2Hs \ O-N=C (I) in which K represents a hydrogen or chlorine atom, and (b) glycerol or honey, optionally mixed with a sugar and/or glycerol or a sugar 9 optionally mixed with glycerol;
Le A 21:!521 l~SS~
component (b) optionally comprising a minor proportion of water.
The present invention further provides a process for the production of a bait for ants according to the invention characterised.in that (a) at least one active compound of the general formula C2~5~ ~ S / CN

in which R has the abovementioned meaning i~ mixed with (b) glycerol or honey, optional.ly.mixed with a sugar and/or glycerol or a sugar, optionally mixed with glycerol, component (b) optionally comprising a minor proportion of water at a low temperature in a kneader and the mixture produced thereby i~ subsequently homogenised and filled into one or more containers.
Finally, it has been found that the baits according to the invention can be used very well for the control of ants~
It must be denoted extremely surprising that the baits according to the invention are more suitable for the control of ants than the baits known from the state of the art which contain phoxim mixed with blackberry syrup or blackberry jam. . Moreover, it could not be expected that the baits according to the invention, in contrast to the~baits containing phoxim based on blackberry syrup or blackberry jam, which are already known, do not exert any development of a repelling effect on ants, even at a Le.A 21 5~1 :,, ` :~
f~
concentration oF active compound of 0.5 to 1.0 per cent by weight.
The baits according to the invention contain as the active ingredients 0,0-diethyl thionophosphoryl-X-oximinophenylacetonitrile (phoxim) and/or 0,0-diethyl thionophosphoryl-~-oximino(2-chlorophenyl)acetonitrile (chlorphoxim). These active compounds, their insecticidal properties and their use for the contrnl oF ants are already known (compare German Patent Specification 1,238,902).
The baits according to the invention contain, apart from the active compound or the mixture of active compounds~
glycerol or honey, optionally mixed with a sugar and/or glycerol or a sugar, optionally mixed with glycerol.
In this connection, honey is to be u~derstood to mean both natural honey and also artificial honey.
Preferred sugars which may be used in the present case are monosaccharides and disaccharides. Examples of particularly preferably suitable monosaccharides are glucose, galacto~e and fructose. Examples of disaccharides which may be mentioned are cane sugar, beet sugar and lactose. Furthermore, invertix is also suitable as a sugar; "invertix" being understood to mean an aqueous sugar solution which contains 26 per cent by weight of water.l ~ai-ts according to the invention are particularly preferred in which the following combinations of active compound and additives are present:
phoxim and glycerol chlorphoxi~ and glycerol phoxim and natural honey chlorphoxim and natural honey Le A 21,,521 phoxim and artificial honey chlorphoxim and artificial honey phoxim, natural honey and.glycerol phox.im, artificial honey and glycerol phoxim and cane sugar phoxim and beet sugar phoxim and lactose phoxim, cane sugar and glycerol phoxim, beet sugar and glycerol phoxim, lactose and glycerol phoxim, natural honey and cane sugar phoxim, beet sugar and natural honey phoxim, artificial honey and lactose phoxim and glucose phoxim, glucose and glycerol phoxim and galactose phoxim, galactose and glycerol phoxim and fructose phoxim, fructose and glycerol phoxim and invertix phoxim, natural honey and invertix.
The content of act.ive compounds in the baits according to the invention can be varied within a certain range. In general~ the total concentrations of active compound of the formula (I) are between 0.01 and 5O by weight, preferably between 0.05 and 2o by weight.
The ratios of the.amounts of sugar, honey and/or glycerol in the products, which are mixed with the active compounds in the case of the baits according to the invention, can be varied within a large range. Thus, in addition to the active compounds of the formula (I)~
the additives present can be only sugar or honey or glycerol including, possibly, a minor proportion of water.
However, the products added can also be mixtures of these Substances. If the product added is a mixture of sugar Le A.21 ~21 ..~
and honey, generally O~l to lO parts by weight, preferably 0.5 to 8 parts by weight, of honey are allotted to l part by weight of cugar. If the product added is a mixture of sugar and glycerol, generally 0.05 to 19 parts by weight, preferably 0.25 to lO parts by weight, of glycerol are allotted to l part by ~eight of sugar. If the product added is a mixture of sugar, honey and glycerol, generally 0.05 to 2 parts by weight of honey and 0.05 to ~ parts by weight of glycerol, preferably O.l to l part by weight of honey and O.l to 5 parts by weight o~ glycerol are allotted to l part by weight of sugar.
In the process according to the invention for the preparation of the new baits for ants; the temperature can be varied within a certain range. In general, the preparation is carried out at a temperature between 10C
and 30C, preFerably at room temperature.
Specifically, the process according to the invention is generally carried out such that at least one active compound of the formula (I) is intimately mixed 2û with the particular additives in the desirsd ratio of amounts in each case, then the mixture thereby produced is homogenised and subsequently filled into the containers designed for practical use.
For the mixing of the components, the kneader used is to be understood as any of the stirring equipment and kneaders customarily used for such purposes. The subsequent homogenisation can be undertaken in any of the equipment that can be customarily used for this purpose.
It is particularly advantageous to use a cylinder mill suitable for homogenising solid or paste~like substances.
When the baits a~cording to the invention contain sugar, it is advantageous to employ the sugar in a finely ground formO
On preparation by the process according to the invention, the bait materials according to the invention result as solid or paste-like, physically and chemically Le A 21 521 -stable, homogeneous products. A check of the shelf-life showed that the bait material in a watertight pack, whiGh prevented losses by evaporation, exhibited no changes for at lest 8 weeks at storage temperatures up ko 54O, and for at least 6 months at storage temperatures up to 40C.
The bait materials according to the invention can be made available for the control of ants in all the customary forms for these types cf bait formulations.
It is particularly advantageous to use the bait material in small containers. For this purpose, the bait material is filled into small containers having a volume of lO to 50 ml. The bait material is either filled directly into the container or is ?reviously added to an absorbent 1S material, such as cellulose or cottonwool~ and then transferred to the container designed for use. The absorbent material can also be present in the container before filling the bait material.
The containers are provided with one or more openings, which are initially closed and which are opened before being used for controlling ants, for example by removing the cover which was previously over them~ so that the ants can reach the bait material.
The present inven~ion thus also provides a method ~ combating ants comprising supplying to the ants at a habikat thereof or elsewhere, a bait for ants according to the present invention.
Using the bait~ according to the invention, ants can be controlled both in domestic and sanitary areas and also in agriculture and horticulture, wherever they are undesirable. The procedure for this is such that the baits according to the invention are placed at the sites infested by ants.
The preparation of the baits according to the invention is illustrated by the following Examples.
Le A 21 521 Preparative Exam~les Comparison Example (i) 999.5 9 of sugar-beet syrup and 0.5g of phoxim were mixed by kneading at room temperature in a kneader for lO minutesO Thereafter, the mixture was homogenised in a cylinder mill and filled in portions9 each of 50 mg, into small plastic containers having-a diameter of 4 cm of a height of l.6 cm. The-containers each had an opening on the side and, after charging with the bait, were closed by means of a lid.
The baits listed in the following Table I were also prepared by the method described in the above Comparison Example, using the additive indicated rather than sugar-beet syrup.

of the particular bait material in each case were ~illed into a plastic container I having a diameter of 4 cm and a height of 1.6 cm. In addition, 50 mg in each case ~f an analogous bait formulation not containing the active compound were placed in a plastic container II
having the measuremen-ts described previously f`or container I. The containers I and II, which each had an opening in the side and, after charging with the bait material, were closed with a plastic lid, wera placed in a larger plastic container III, which was open at the top and had a diame-ter of 11.5 cm and a height of 3.4 cm. The walls of this plastic con-tainer III were coated with Teflon in order to prevent the ants crawling out. In each case, the container III was connected via a 1 cm long plas-tic tubing, which had an internal diameter of 0.5 cm, with a glass tube which was 20 cm long and had an internal diameter of 2.3 cm. The glass tube was 25o filled wi-th mois-t peat Le A 21 521 and contained 20 ants (workers) and 50 ant larvae. The interior of the glass tube was kept dark by a black wrapper from a box for photographic film. In this design of experiment, the ants were allowed the option of rejecting the bait which cnntained the active compound if a repel-lent effect developed and of feeding only from the bait which contained no active compound.
The degree of extermination in O was determined after 7 days. In this context, 100o indicated that all the ants (workers) had been killed. 0O indicated that no ant was killed.

Feeding discrimination test on a~ts .
Teet animals: Lasius niger (workers and larvae) For the preparation of a suitable bait, 50 m~
of the particular bait material in each case were ~illed into a plastic container I having a diameter of 4 cm and a height of 1.6 cm. In addition, 50 mg in each case ~f an analogous bait formulation not containing the active compound were placed in a plastic container II
having the measuremen-ts described previously f`or container I. The containers I and II, which each had an opening in the side and, after charging with the bait material, were closed with a plastic lid, wera placed in a larger plastic container III, which was open at the top and had a diame-ter of 11.5 cm and a height of 3.4 cm. The walls of this plastic con-tainer III were coated with Teflon in order to prevent the ants crawling out. In each case, the container III was connected via a 1 cm long plas-tic tubing, which had an internal diameter of 0.5 cm, with a glass tube which was 20 cm long and had an internal diameter of 2.3 cm. The glass tube was 25o filled wi-th mois-t peat Le A 21 521 and contained 20 ants (workers) and 50 ant larvae. The interior of the glass tube was kept dark by a black wrapper from a box for photographic film. In this design of experiment, the ants were allowed the option of rejecting the bait which cnntained the active compound if a repel-lent effect developed and of feeding only from the bait which contained no active compound.
The degree of extermination in O was determined after 7 days. In this context, 100o indicated that all the ants (workers) had been killed. 0O indicated that no ant was killed.
The composition of the baits tested, the contents of active compounds and the O of ants killed after 7 days can be seen from the following table.
