l pests. Insecticides for agricultural and horticultural use, control agents for internai animal ;

parasites and control agents forexternal animal parasites are preferred.

The pest control agents of the invention may be prepared using, aside from a compound of chemical formula (I), a carrier suitable for the intended method of use.

When the pest control agent of the invention is an agricultural pest control agent, the activei ingrédient is generally mixed with a suitable solid carrier, liquid carrier, gaseous carrier, surfactant,|

i. dispersant and other adjuvants, and the agent is furnished in any desired form, such as ani emulsifiable concentrate, liquid formulation, suspension concentrate, wettable powder, flowable concentrate, dust, granules, tablets, oil solution, aérosol or smoking agent.

Illustrative examples of solid carriers include talc, bentonite, clay, kaolin, diatomaceous earth, vermiculite, white carbon and calcium carbonate.

Illustrative examples of liquid carriers include alcohols such as méthanol, n-hexanol andί i' ethylene glycol, ketones such as acetone, methyl ethyl ketone and cyclohexanone, aliphatic:

hydrocarbons such as n-hexane and kerosene, aromatic hydrocarbons such as toluene, xylene[

F and methyl naphthalene, ethers such as diethyl ether, dloxane and tetrahydrofuran, esters such asj j ethyl acetate, nitriles such as acetonitrile and isobutyronitrile, acid amides such as dimethylformamide and dimethylacetamide, vegetable oils such as soy oil and cottonseed oil, dimethylsulfoxide, and water.

Illustrative examples of gaseous carriers include liquid propane gas, air, nitrogen, carbon dioxide and dimethyl ether.

Surfactants and dispersants which may be used for the purpose of émulsification, dispersion, spreading, sticking and the like include alkylsulfuric acid esters, alkyl(aryl)sulfonic acid salts, polyoxyalkylene alkyl(aryl) ethers, polyol esters, and ligninsulfonic acid salts.j

Adjuvants which may be used for improving the properties of the formulation includel carboxymethylcellulose, gum arable, polyethyiene glycol and calcium stéarate.

The above carriers, surfactants, dispersants and adjuvants may each be used singly or in' combination, as needed.

The active ingrédient content within the above formulation, although not particularly limited, is typically set to from 1 to 75 wt% in emulsifiable concentrâtes, from 0.3 to 25 wt% in dusts, from to 90 wt% in wettable powders, and from 0.5 to 10 wt% in granules.

The compounds of chemical formula (I), formulations containing these compounds, and mixtures of these with other pest control agents may be suitably applied to, for example, insect pests, plants, plant propagation materials (e.g., seeds, plant foliage, roots, germinated plants, and seedlings), soils, nutrient solutions in hydroponics, solid media in hydroponics, or rooms needed to prevent infestation by pests. Plants subjected to such application include genetically modified crops.

Such application may be carried out before and after pest infestation.

In particular, the compounds of chemical formula (le), formulations containing the same, and combinations of these with other pest control agents, by being applied at an effective dose to a target selected from the group consisting of seeds, roots, tubers, buibs, rhizomes, germinated plants, seedlings, soils, nutrient solutions in hydroponics and solid media in hydroponics, and thus being allowed to penetrate and translocate into the plant, are able to control pests.

In cases where the above targets of application are the seeds, roots, tubers, buibs or rhizomes of plants, preferred examples of the method of application are not particularly limited provided pénétration and translocation is unhindered and include, for example, dipping methods, dust coating methods, smearing methods, spraying methods, pellet methods and film coating methods.

in the case of seeds, examples of the method of application include dipping, dust coating, smearing, spraying, pellet application, film coating and fumigation. Dipping is a method for immersing the seeds in a liquid solution of the pest control agent. Dust coating methods include dry dust coating which involves coating the pest control agent in powdered form onto dry seeds, and wet dust coating which involves coating the pest control agent in powdered form onto iightly water-moistened seeds. Other methods are a smearing method for applying the pest control agent in a suspended form onto the surface of seeds within a mixer, and a spraying method for spraying the same onto the surface of the seeds. Additional methods of application include a peliet method in which, when the seeds are formed together with a filler into pellets of a given size and shape, treatment is carried out by mixing the pest control agent with the filler; a film coating method which entails coating the seeds with a film containing the pest control agent; and a fumigation method which entails disinfection of the seeds with the pest control agent that has been gasified within a closed vessel.

In the case of application to germinated plants and seedlings, these plants may be protected by application, via systemic or partial treatment by dipping, following germination and following emergence from the soil, but prior to transplantation.

In the case of application to seeds, roots, tubers, bulbs or rhizomes, an additional considération is planting or dipping the seeds, roots, tubers, bulbs or rhizomes for a time sufficient to allow pénétration and translocation of the pest control agent. In such a case, the time and température at which dipping is carried out may be suitably determined by a person skilled in the art in accordance with the target of application and the type and dose of the chemical. In addition, the pénétration and transiocation time is not subject to any particular limitation, and may be, for example, 1 hour or more. The température during pénétration and translocation is, for example, from 5to 45°C.

Methods of application to the soil are exemplified by the application of the inventive compound, formulations containing the same, or granules of mixtures thereof with other pest control agents, either into soil or onto soil. Preferred soil application methods are spraying, band application, furrow application and planting hole treatment. Here, spraying treatment is surface treatment over the entire surface area to be treated, and encompasses subséquent mechanical introduction into the soil.

Another useful method of soti treatment in volves application by drenching soil with a solution of the inventive compounds, a formulation containing the same, or a mixture thereof with another pest control agent that has been emulsified or dissolved in water.

in the case of application to nutrient solutions in nutricultural Systems for the production of vegetables and flowering plants, such as solid medium cultivation, including hydroponics, sand culture, the nutrient film technique (NFT) and the rock wool technique, it is obvious that the inventive compounds or formulations containing the same, or mixtures of these with other pest control agents, can be directly applied to an artificial plant growth medium containing vermiculite or a solid medium containing an artificial mat for raising seedlings.

In the above application step, the effective dose of the compound of formula (1) or a sait thereof, or of a compound of formula (le) or a sait thereof, is preferably an amount sufficient for the compound of formula (1) or formula (le) to penetrate and translocate in the subséquent pénétration and translocation step.

This effective dose may be suitably decided while taking into considération such factors as the properties of the compound, the type and amount of the target of application, the length of the subséquent pénétration and translocation step, and the température. For example, in the case of application to seeds, the dose of the compound of formula (1) or a sait thereof, or of the compound of formula (le) or a sait thereof, is preferably from 1 g to 10 kg, and more preferably from 10 g to 1 kg, per 10 kg of seed. In the case of application to soil, the dose of the compound of formula (1) or a sait thereof, or of the compound of formula (le) or a sait thereof, is preferably from 0.1 g to 10 kg, and more preferably from 1 g to 10 kg, per 10 ares of cultivated land. In the case of foliar application to plants, the dose of the compound of formula (1 ) or a sait thereof, or of the compound of formula (le) or a sait thereof, is preferably from 0.1 g to 10 kg, and more preferably from 1 g to 1 kg, per 10 areas of cultivated land.

In cases where the pest control agent of the invention is an agent for controlling animal parasitic pests, it may be furnished as, for example, a liquid formulation, an emulsifiable concentrate, liquefied drop formulation, a spray, a foam formulation, tablets, granules, fine granules, a dust, capsules, tablets, a chewable préparation, an injection, a suppository, a cream, a shampoo, a rinse, a resin formulation, a smoking agent or as poisonous bait. Supply as a liquid formulation or a liquid formulation for drop is especially preferred.

In liquid formulations, adjuvants such as common emulsifying agents, dispersants, spreaders, wetting agents, suspending agents preservatives and propellants may also be included, in addition to which ordinary film-forming agents may be included as well. Surfactants which may be used for émulsification, dispersion, spreading, sticking and the like include soaps, polyoxy alkylene alkyl(aryl) ethers, polyoxyethylene alkylallyl ethers, polyoxyethyiene fatty acid esters, higher alcohols and alkyl aryl sulfonates. Examples of dispersants include casein, gelatin, polysaccharides, lignin dérivatives, sugars and synthetic water-soîuble polymers. Examples of spreading and wetting agents include glycerol and polyethylene glycol. Examples of suspending agents include casein, gelatin, hydroxypropyl cellulose and gum arable. Examples of stabilîzers include phenol-based antioxidants (e.g., BHT, BHA), amine-based antioxidants (e.g., diphenylamine), and organosulfur-based antioxidants. Examples of preservatives include methyl p-oxybenzoate, ethyl p-oxybenzoate, propyl p-oxybenzoate and butyl p-oxybenzoate. The above carriers, surfactants, dispersants and adjuvants may each be used, as needed, either singly or as combinations thereof. In addition, fragrances and synergists may also be included. In a liquid formulation, it is suitable for the active ingrédient content in the pest control agents of the invention to be generally from 1 to 75 wt%.

Carriers used for preparing a cream formulation are exemplified by non-volatile hydrocarbons (e.g., liquid paraffin), lanolin fats added with water and oils, higher fatty acids, fatty acid esters, vegetable oils, silicone oils, and water. In addition, emulsifying agents, humectants, antioxidants, fragrances, borax and ultraviolet absorbera may each be used, either singly or in combination thereof, as needed. Examples of emulsifying agents include fatty acid sorbitans, poiyoxyethylene alkyl ethers and fatty acid polyoxyethylenes. An active ingrédient content within the inventive pest control agent of generally from 0.5 to 70 wt% is appropriate in cream formulations.

In the case of capsules, pills or tablets, the active ingrédient within the inventive composition is suitably dîvided up and mixed with a diluting liquid or a carrier such as starch, lactose or talc, in addition to which a disintegrant such as magnésium stéarate and/or a binder are added. if necessary, the formulation may be tableted prior to use.

1,2-bis(tosyloxy)ethane (8.86 g; 24.0 mmol) was dissolved in 100 mL of anhydrous dimethylformamide, following which 2.00 g (12.0 mmol) of N-[(6-chloropyridin-3yl)methyl]cyanamide synthesized by the method in a comparative example, 500 mg of 60% NaH (net weight, 300 mg; 13.2 mmol) and 44 mg of Kl were added in this order under ice cooling, and the system was stirred at room température for 80 minutes. Following reaction completion, methanol was added a little at a time at 0°C, then the reaction was stopped by adding water. Next, ethyl acetate and 1% hydrochloric acid were added to the system and liquid-liquid extraction was carried out. The organic phase was washed with 1% hydrochloric acid, dried over anhydrous magnésium sulfate and concentrated under reduced pressure, then purified by silica gel column chromatography (hexane/ethyl acetate = 2:8 -> 6:4). When the fractions containing the target compound were collected and concentrated, dimethylformamide remained in the concentrate. Hence, a small amount of ethyl acetate was added and the concentrate was washed twice with 1% hydrochloric acid, then dried over anhydrous magnésium sulfate and concentrated under reduced pressure to remove the dimethylformamide, giving 1.43 g of 2-[N-(6-chloro-3pyridylmethyl)cyanamide]ethyl 4-methylbenzenesulfonate (Compound 84). The yield was 33%.

Anhydrous acetonitrile (3 mL) was added to 45 mg (0.28 mmol) of potassium ethyl xanthate, a solution of 50 mg (0.14 mmol) of 2-[N-(6-chloro-3-pyridylmethyl)cyanamide]ethyl 4methylbenzenesulfonate synthesized by the above-described method dissolved in 2 mL of acetonitrile was added thereto, and the mixture was stirred at 50°C for 50 minutes. Following reaction completion, the reaction mixture was concentrated under reduced pressure, ethyl acetate and 1% hydrochloric acid were added, and liquid-liquid extraction were carried out. The organic phase was dried over anhydrous magnésium sulfate, then concentrated under reduced pressure, purified on a préparative TLC plate (one 0.5 mm plate, liquid-liquid extraction with hexane/ethyl acetate = 2:3), giving 23 mg of the target compound (yield, 18%).

Synthesis_______Example_______13:______________2-[N-(6-chloro-3-pyridvlmethyl)cvanamide1ethyl benzylfethypcarbamodithioate (Compound 85)

Benzyl ethyl amine (55 mg, 0.41 mmol) was dissolved in 5 mL of anhydrous tetrahydrofuran, 46 mg (0.41 mmol) of potassium t-butylate was added, and the mixture was stirred at room température for 20 minutes. Next, 49 qg (62 mg, 0.41 mmol) of carbon disulfide, 50 mg (0.14 mmol) of 2-[N-(6-chloro-3-pyridylmethyl)cyanamide]ethyl 4-methylbenzenesulfonate (Compound 84) synthesized by the method of Synthesis Example 12 dissolved in 3 mL of anhydrous tetrahydrofuran, and 5 mg of potassium iodide were added in this order, and the system was stirred at 40°C for 1 hour. Following reaction completion, a small amount of water was added to stop the reaction, the reaction mixture was filtered using Celite, and the filtrate was concentrated. The concentrate was purified by silica gel column chromatography (hexane/ethyl acetate = 7:3), giving 41 mg of the target compound (yield, 72%).

i 10	Crude Enzyme Extract As mentioned in Pest Management Science, 59(3), 347-352 (2003) and the Journal of Pesticide Science, 29(2), 110-116 (2004), imidacloprid is known to be inactivated by incurring oxidative metabolism, which is thought to be one mechanism of acquiring résistance to this agent. The following experîment was carried out to confirm the effects in pests which hâve acquired such
15	résistance. An amount of 10 mL of a potassium phosphate buffer solution (pH 7.4, containing 1 mM EDTA) was added to adult house flies (0.645 g), and the flies were thoroughly homogenized in a Physcotron (Niti-On Medical and Physical Instruments Manufacturing Co.). The homogenate was then centrifuged at 10,000 g for 15 minutes. The resulting supernatant was additionally
20	centrifuged at 100,000 g for 60 minutes, giving a precipîtate. The precipîtate was dissolved in 1 mL of a potassium phosphate buffer, and the resulting solution was used as the crude enzyme extract. The enzyme extraction operations were ail carried out on ice or at 4°C. The reagents were mixed in the following proportions within a 1.5 mL tube, and the reaction was effected at 25°C for 40 hours. Following the reaction, 1 mL of acetone was added
25	and the mixture was stirred, following which the precipîtate that formed was centrifuged at 12,000 rpm for 5 minutes. The supernatant acetone was distilled off, and the precipîtate was injected into a liquid chromatograph-mass spectrometer (LC/MS) and analysis was carried out. Above crude enzyme extract: 300 pL
