PATENTS ACT 1990 DIVISIONAL APPLICATION NAME OF APPLICANT: Merial DP Australia Documents received dn: 12 JUL 2001 ADDRESS FOR SERVICE: Batch No: I DAVIES COLLISON CAVE Patent Attorneys 1 Little Collins Street Melbourne, 3000.
INVENTION TITLE: "Insecticidal combination effective against fleas on mammals, particularly cats and dogs" The following statement is a full description of this invention, including the best method of performing it known to us: P.OPER\MKR\SPECI\731994-divdoc- 2/07/01 -1- INSECTICIDAL COMBINATION TO CONTROL MAMMAL FLEAS, IN PARTICULAR FLEAS ON CATS AND DOGS This is a divisional of application 25129/97, the disclosure of which is included herein in its entirety by way of reference.
The present invention relates to an improvement to the processes for controlling mammal fleas and in particular fleas on cats and dogs. The invention also relates to a novel composition for this use, based on a synergistic combination of parasiticides which are already known.
e• Lastly, the invention relates to the use of such alreadyknown parasiticides for the preparation of such a composition.
A novel class of l-N-arylpyrazole-based insecticides has been described in patents EP-A-295,217 and EP-A-352,944.
oo The compounds of the classes defined in these patents are highly active, and one of these compounds 1-[2,6-C1 2 4-CF 3 phenyl]3-CN 4-[SO-CF3]5-NH 2 pyrazole, whose common name is fipronil, has proven to be particularly effective not only against crop parasites but also against mammal ectoparasites and in particular, but not exclusively, fleas, ticks, flies and myiases.
Compounds with an ovicidal and/or larvicidal effect on the immature stages of various ectoparasites are already known, for example from patent US-A-5,439,924. Among these compounds (IGR) are featured insect growth regulator compounds which act either by blocking the development of the immature stages (eggs and larvae) into adult stages, or by inhibiting the synthesis of chitin.
f it P:\OPER\MKRSPECI\731994-div.doc- 2/07/01 -1A- Patent FR-A-2,713,889 is moreover known, which generally describes the combination of at least one compound of IGR (insect growth regulator) type, comprising compounds with juvenile hormone activity and chitin synthesis inhibitors, with at least one of three N-aryldiazole compounds, in particular fipronil, to control many harmful insects belonging to very varied orders.
The compositions may be used in very diverse forms, although the applications, for example veterinary, healthcare or plant-protection applications, for which these different forms are *e **ga P: OPER MKR SPECI 25129-97-044 doc-1.01 -2designed are not specified, nor are the parasites for which they are respectively intended.
The only application which may be thought to be veterinary is associated with the example of the manufacture of a pesticidal collar which is a slow-release formulation.
The invention proposes to improve the processes for controlling fleas and/or ectoparasites (particularly ticks) in small mammals, and in particular in cats and dogs.
An object of the invention is, in particular, to use 10 already-known parasiticides in order to prepare a Ce composition which is highly active against the fleas of these animals.
For the purposes of the present invention, the term flea is understood to refer to all the usual or accidental species of parasitic flea of the order Siphonaptera, and in particular the species Ctenocephalides, in particular C.
felis and C. canis, rat fleas (Xenopsylla cheopis) and human fleas (Pulex irritans).
The very high efficacy of the process and of the composition according to the invention implies not only high immediate efficacy but also very long-lasting efficacy after the animal has been treated.
The subject of the invention is a process for controlling the fleas and/or ectoparasites (particularly ticks) of small mammals, and in particular cats and dogs, over a long period, characterized in that the animal is treated by locally depositing a composition of the invention on the skin, preferably localized over a small surface area (spot-on application), in parasiticidally effective doses and proportions.
