  1.  (Zo["o]l.)  A  small  hemipterous  insect  ({Phylloxera 
  vastatrix})  allied  to  the  aphids.  It  attacks  the  roots  and

  other  wingless.  One  form  produces  galls  on  the  leaves 
  and  twigs,  another  affects  the  roots,  causing  galls  or 
  swellings,  and  often  killing  the  vine.
