Novel pyrazolines of the formula (I) CHEM wherein R1 and R2 represent hydrogen atom, C5 PI 8 alkyl group, or unsubstituted or halogen-substituted phenyl group, A represents phenyl group which may be substituted by at least one group selected from the class consisting of halogen atom, C5 PI 8 alkyl group, C5 PI 8 alkoxy group, halogeno-C5 PI 8 alkyl group, halogeno-C5 PI 8 alkoxy group, nitro group, haloalkylenedioxy group, unsubstituted or halogen-substituted phenyl group, and unsubstituted or halogen-substituted phenoxy group, or A represents halogen-substituted 3-pyridyl group, B represents phenyl group which may be substituted by halogen, or B represents halogen-substituted or C5 PI 8 alkoxy-substituted 3-pyridyl group, and X and Y individually represent hydrogen atom, halogen atom, C5 PI 8 alkyl group, halogeno-C5 PI 8 alkyl group, halogen-C5 PI 8 alkoxy group or halogeno-C5 PI 8 alkylthio group, or X and Y together form haloalkylenedioxy group, with the proviso that X and Y do not simultaneously represent hydrogen atom, and with the other proviso that at least one of A and B represents halogen-substituted pyridyl group, and with the further proviso that, when R1 and R2 simultaneously represent hydrogen atom, then A represents phenyl group substituted by at least one group selected from the class consisting of halogeno-C5 PI 8 alkoxy group, nitro group, halomethylenedioxy group, unsubstituted or halogen-substituted phenyl group and unsubstituted or halogen-substituted phenoxy group, or at least one of X and Y represents halogeno-C5 PI 8 alkoxy group or halogeno C5 PI 8 alkylthio group, or X and Y together form haloalkylenedioxy group.
