ABSTRACT OF THE DISCLOSURE The insecticidal transparent emulsion of the present invention is obtained by mixing (A) at least one pyrethroidal insecticide selected from the group consisting of 3-phenoxybenzyl chrysanthemate, 3-allyl-2-methyl-4-oxocyclopent-2-enyl chrysanthemate, 3-allyl-2-methyl-4-oxocyclopent-2-enyl 2,2,3,3-tetramethylcyclopropanecarboxylate, 2-methyl-4-oxo-3-(2-propynyl)cyclopent-2-enyl chrysanthemate and .alpha.-cyano-3-phenoxybenzyl chrysanthemate, or a mixture of at least one pyrethroidal insecticide selected from the group consisting of 3-phenoxybenzyl chrysanthemate, 3-allyl-2-methyl-4-oxocyclopent-2-enyl chrysanthemate, 3-allyl-2-methyl-4-oxocyclopent-2-enyl 2,2,3,3-tetramethylcyclopropanecarboxylate, 2-methyl-4-oxo-3-(2-propynyl)cyclopent-2-enyl chrysanthemate and .alpha.-cyano-3-phenoxybenzyl chrysanthemate and at least one pyrethroidal insecticide selected from the group consisting of .alpha.-cyano-3-phenoxybenzyl 2,2,3,3-tetramethyl- cyclopropanecarboxylate, 3,4,5,6-tetrahydrophthalimidemethyl chrysanthemate, 3-phenoxybenzyl 3-(2,2-dichlorovinyl)-2,2- dimethylcyclopropanecarboxylate and l-ethynyl-2-methyl-2-pentenyl chrysanthemate, as an active ingredient, (B) a polar solvent-containing mixed surface active agent containing at least one metal alkylbenzene- sulfonate, at least one nonionic surface active agent having an HLB (hydro- and lipophilicity balance) of 10 to 18 and at least one polar solvent, and (C) water, so that the content of (B) in the mixture is equal to or more than that of (A) and 6% by weight or less and then diluting the resulting mixture. The insecticidal transparent emulsion of the present invention has a merit that the solution state is unchanged even when the environmental temperature sharply moves up and down.
