Patent ID: 7262214

Claim:
A method for interrupting the transmission of mosquito-borne diseases from a first actual or putative amplifying or incipient host, which is a bird, to a second actual or putative amplifying or incipient host, which is a horse, which comprises applying or administering a formulation comprising at least one 1-N-arylpyrazole derivative to said first actual or putative amplifying or incipient host in an amount capable of killing mosquitoes after feeding on the first actual or putative amplifying or incipient host and thereby interrupting the transmission of mosquito-borne diseases from the first actual or putative amplifying or incipient host to the second actual or putative amplifying or incipient host, wherein the at least 1-N-arylpyrazole derivative has the formula in which R 1 is CN; R 2 is S(O) n R 3 ; R 3 is haloalkyl; R 4 is NH 2 ; R 11 and R 12 represent, independently of one another, a halogen atom; R 13 is a haloalkyl; n is an integer equal to 0, 1 or 2; X is a C—R 12 radical; and the formulation is suitable for applying or administering the 1-N-arylpyrazole to a bird.
