Abstract
Disclosed are novel phosphoric ester derivatives of the formula (I): ##STR1## wherein R.sup.1 and R.sup.2 each represents a lower alkyl group; R.sup.3 represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group or a lower alkylthio group; X.sup.1 and X.sup.2 are the same or different and each represents a hydrogen atom or a halogen atom; and Y represents an oxygen atom or a sulfur atom, and insecticidal and miticidal compositions containing said derivatives.
