Phosphoric or thiophosphoric esters of 5(3)-hydroxypyrazoles are disclosed having the formula: ##STR1## wherein: R=H; alkyl with 1-7 carbon atoms optionally substituted with halogens, CN, and carboalkoxy groups; phenyl optionally substituted; benzyl; alkenyl; or alkynyl; X=halogen; --SR; --OR; --N(R).sub.2 ; or ##STR2## where Y is equal to or different from each other, and=H; C.sub.1 -C.sub.3 alkyl; halogen; --SR; --OR; or --N(R).sub.2 ; Z=S; or O; and R.sup.1 and R.sup.2, equal to or different from each other, are: alkoxyls; alkyls; phenyls; or alkylthio- or alkyl-amino-groups. These are useful as insecticides, acaricides and nematodacides. Also disclosed are 5(3)-hydroxypyrazoles having the formula: ##STR3## wherein: R=H; alkyl with 1-7 carbon atoms, optionally substituted with halogen atoms, CN, and carboalkoxy-groups; phenyl optionally substituted; benzyl; alkenyl; or alkynyl; X=halogen; --SR; --OR; --N(R).sub.2 ; or ##STR4## where Y is equal to or different from each other, and =H; C.sub.1 -C.sub.3 alkyl; halogen; --SR; or --OR; or --N(R).sub.2 ; and provided further that when in formula I, X=halogen or --N(R).sub.2 ; the R group, bound to the pyrazolic nitrogen, is different from phenyl.
