    • NEW MATERIAL:A compound of formula I (X is O, S; R
      1 , R
      2 are H, halogen, lower alkyl, lower alkoxy, lower haloalkoxy, lower haloalkylthio, methylenedioxy; R
      3 , R
      4 are H, methyl).
      EXAMPLE: 3-(2-Fluoroethoxy)benzyl benzyl ether.
      USE: Acaricide and insecticide: it is effective against various kinds of phytoparasitic acari such as Tetranychus urticae or Panonychus citri to kill them even at their egg and larva stages, whether they are sensitive or resistant to chemicals. Further it is effective against harmful Lepidoptera such as Spodoptera litura FABRICUS and Hemiptera such as Laodelphax striatellus.
      PREPARATION: The reaction of a compound of formula II [when one of Y and Z is halogen, the other is X-M (M is H, alkali or alkaline earth metal)] with another compound of formula III gives the compound of formula I .
