COMPOSITION AND METHOD FOR CONTROLLING HOUSE INSECT PEST (I) This application is a Continuation of U.S. application Ser. No. 10/504,158, filed on May 16, 2005, now abandoned, which was filed as a 371 of International Application PCT/ JPO3/01711, filed on Feb. 18, 2003. TECHNICAL FIELD 10 (O), The present invention relates to a composition for control wherein Y is a haloalkyl group, m is 0 or 1, and Q is ling a house insect pest, which comprises, as active ingredi ents, at least two compounds selected from the group consist 15 X RI ing of (a) a certain specific pyridine compound or its salt, (b) | / a benzoylurea compound, (c) a pyrethroid compound and (d) -C-N a certain specific hydrazone compound or its salt, particularly to a composition for controlling termites, ants or cock Ye roaches. Further, it relates also to a composition for control ling a house insect pest, which comprises, as an active ingre or a Substituted or unsubstituted heterocyclic group, (wherein dient, the above hydraZone compound or its salt. X is an oxygen atom or a sulfur atom, R' and R are respec tively independently a hydrogenatom, a Substituted or unsub stituted alkyl group, a Substituted or unsubstituted alkenyl 25 group, a Substituted or unsubstituted alkynyl group, a Substi BACKGROUND ART tuted or unsubstituted cycloalkyl group, a C(W)R group, a —OR group, a S(O)R group, a NHR' group, Pyridine compounds may, for example, be those described in e.g. U.S. Pat. No. 5,360,806, WO98/57969 and WO 02/34050. Hydrazone compounds may be those described in 30 S R7, U.S. Pat. No. 5,288,727 and Japanese patent 307192. As conventional agents for controlling termites, organo phosphorus compounds such as chlorpyrifos, or pyrethroids -(DN may, for example, be mentioned. Further, as agents for con 35 trolling ants, hydramethylnon, lithium sulfonate, organo a C(R)=NO R group or a substituted or unsubstituted phosphorus compounds, carbamates, or pyrethroids, may, for aryl group, or R' and R may form a =C(R')R'' group or example, be mentioned. Further, as agents for controlling may form a C-C 5-membered or 6-membered heterocyclic cockroaches, pyrethroids or organophosphorus compounds, group which may contain a nitrogenatom oran oxygenatom, may, for example, be mentioned. However, among them, 40 together with an adjacent nitrogenatom, R is a substituted or unsubstituted alkyl group, a Substituted or unsubstituted alk there are some which are feared to present toxicity against enyl group, a Substituted or unsubstituted alkynyl group, a mammals or adverse effects to environment. Under the cir Substituted or unsubstituted cycloalkyl group, a Substituted or cumstances, a new agent for controlling a house insect pest is unsubstituted aryl group, analkoxy group, an alkylthio group desired. 45 or a mono- or dialkylamino group, R is a hydrogen atom, a Substituted or unsubstituted alkyl group, a Substituted or DISCLOSURE OF THE INVENTION unsubstituted alkenyl group, a Substituted or unsubstituted alkynyl group, a Substituted or unsubstituted cycloalkyl The present inventors have conducted an extensive group, a Substituted or unsubstituted aryl group, a Substituted 50 or unsubstituted heterocyclic group ora-COR group, R is research for an agent for controlling a house insect pest. As a an alkyl group or a dialkylamino group, R is an alkyl group result, they have found specifically that by combining at least oran aryl group, Zis Nora-C R' group, R is a hydrogen two compounds selected from the group consisting of (a) atom, a halogen atom, a Substituted or unsubstituted alkyl certain specific pyridine compounds or salts thereof, (b) ben group, an alkoxy group, an alkylthio group or a nitro group. Zoylurea compounds, (c) pyrethroid compounds and (d) cer 55 Rand Rare respectively independently a hydrogenatom, a tain specific hydrazone compounds or salts thereof, as active Substituted or unsubstituted alkyl group, a Substituted or ingredients, particularly excellent effects for controlling unsubstituted alkenyl group, a Substituted or unsubstituted house insect pests can be expressed, and that certain hydra alkynyl group, a Substituted or unsubstituted aryl group or a Zone compounds or salts thereof have excellent effects for substituted or unsubstituted heterocyclic group, R'' and R' controlling house insect pests. The present invention has been 60 are respectively independently a hydrogenatom, a Substituted accomplished on the basis of this discovery. or unsubstituted alkyl group, a Substituted or unsubstituted alkenyl group, a Substituted or unsubstituted heterocyclic Namely, the present invention provides a composition for group, a N-(R')R group, a substituted or unsubstituted controlling a house insect pest, which comprises, as active alkoxy group, a Substituted or unsubstituted alkylthio group, ingredients, at least two compounds selected from the group 65 R'' and R' are respectively independently a hydrogenatom, consisting of (a) a pyridine compound of the formula (I) or its a Substituted or unsubstituted alkyl group, a Substituted or salt: unsubstituted alkenyl group, a Substituted or unsubstituted US 7,655,677 B2 3 4 alkynyl group, a Substituted or unsubstituted aryl group or a tuted with a halogen, alkyl, alkoxy, haloalkoxy, alkylthio. substituted or unsubstituted heterocyclic group, W' is an oxy phenyl (which may be further substituted with a halogen, gen atom or a Sulfur atom, and n is 1 or 2); (b) a benzoylurea alkyl, alkoxy, nitro, haloalkyl or phenoxy group), phenoxy, compound; (c) a pyrethroid compound and (d) a hydrazone phenylthio, cycloalkyl or cycloalkoxy group; a hydroxy compound of the formula (II) or its salt: group; a cyano group; a cycloalkyl group; an imino group; a —C(W)R'' group (W is an oxygen atom or a sulfur atom, R'' is a hydrogen atom; an amino group; an amino group (II) Substituted with one or two alkyl group; an alkyl group; an R5 M alkoxy group; an alkylthio group or an aryl group); a —OC N 10 (W)R group (R' is an aryl group substituted with an alkyl RSC V o orhaloalkyl group); oran alkylsulfonyl group. Also, when the :X ) is R6' y R' above Substituent is an imino group, it may form an amidino group or animidate group, together withanamino group oran / CH-V 5. alkoxy group. 15 Also, other examples of a substituent of a substituted or unsubstituted alkyl group defined as R' or R included in the wherein each of R', R and R", which are independent of Q' group in the formula (I), include a 4-haloalkyl-3-pyridin one another, is a hydrogen atom, a halogen atom, an alkyl ecarboxyamide group, a N-methyl-4-haloalkyl-3-pyridin group which may be substituted by halogen, or an alkoxy ecarboxyamide group, a 4-haloalkyl-3-pyridinecarboxya group which may be substituted by halogen, R is a halogen mide-N-alkylenoxy group, and the like. atom, an alkyl group which may be substituted by halogen, or Thus, the above compound is a dimer of a compound of the an alkoxy group which may be substituted by halogen, R is formula (I) connected by way of an alkylene chain. In the a hydrogenatom, or an alkyl group, R is X"CO (wherein same manner as above, the active ingredient of the composi X7 is a hydrogen atom, or an alkyl group), or XOCO tion for controlling a house insect pest of the present invention (wherein X is an alkyl group), or RandR" together form 25 includes a trimer.
