Disclosed is an insecticidal suspension concentrate composition comprising by weight based on the total weight of the composition: (a) from about 0.3 to about 30% of 3-bromo-1-(3-chloro-2-pyridinyl)-N-[4-cyano-2-methyl-6-[(methylamino)carbonyl]phenyl]-1H-pyrazole-5-carboxamide； (b) from about 5 to about 70% of a nonionic ethylene oxide-propylene oxide block copolymer component having a water solubility of at least about 5% by weight at 20° C., a hydrophilic-lipophilic balance value ranging from about 5 to about 18 and an average molecular weight ranging from about 900 to about 20000 daltons； and (c) from about 20 to about 95% of water. Also disclosed is a method for controlling an insect pest comprising diluting said suspension concentrate composition with water to form a diluted composition, and contacting the insect pest or its environment with an insecticidally effective amount of said diluted composition.組成物の総重量を基準にした重量で：（ａ）約０．３～約３０％の３－ブロモ－１－（３－クロロ－２－ピリジニル）－Ｎ－［４－シアノ－２－メチル－６－［（メチルアミノ）カルボニル］フェニル］－１Ｈ－ピラゾール－５－カルボキサミドと；（ｂ）２０℃で少なくとも約５重量％の水溶性、約５～約１８の範囲の親水性－親油性バランス値および約９００～約２００００ダルトンの範囲の平均分子量を有する、約５～約７０％の非イオン性エチレンオキシド－プロピレンオキシドブロックコポリマー成分と；（ｃ）約２０～約９５％の水とを含む殺虫剤懸濁液濃縮組成物が開示される。前記懸濁液濃縮組成物を水で希釈して、希釈された組成物を形成する工程と、昆虫有害生物またはその環境を殺虫的に有効な量の前記希釈された組成物と接触させる工程とを含む、昆虫有害生物を防除するための方法も開示される。
