  Pemphigus 
  betae 
  is 
  the 
  most 
  important 
  pest 
  of 
  the 
  sugar-beet 
  in 
  

   Montana, 
  and 
  each 
  year 
  does 
  considerable 
  injury, 
  the 
  tonnage 
  in 
  badly 
  

   infested 
  fields 
  sometimes 
  being 
  reduced 
  to 
  a 
  third. 
  The 
  hfe-cycle 
  

   of 
  the 
  insect 
  has 
  been 
  worked 
  out 
  and 
  is 
  briefly 
  as 
  follows. 
  Wingless- 
  

   viviparous 
  females 
  are 
  found 
  upon 
  the 
  roots 
  of 
  beets, 
  weeds 
  and 
  grasses 
  

   all 
  the 
  year 
  round 
  ; 
  in 
  the 
  autumn 
  winged 
  individuals 
  are 
  produced 
  

   which 
  fly 
  to 
  cottonwood 
  trees 
  and 
  deposit 
  the 
  true 
  sexes 
  ;
