  Life 
  history. 
  Gladioli 
  bulbs 
  are 
  kept 
  by 
  growers 
  in 
  large 
  

   warehouses, 
  the 
  temperature 
  bein.e: 
  maintained 
  at 
  about 
  40 
  degrees 
  

   throughout 
  the 
  winter. 
  This 
  insect 
  is 
  evidently 
  unable 
  to 
  breed 
  

   under 
  these 
  conditions. 
  As 
  spring 
  advances 
  and 
  the 
  house 
  begins 
  

   to 
  warm 
  up 
  in 
  Alarch, 
  the 
  aphids 
  appear 
  in 
  large 
  numbers, 
  repro- 
  

   ducing 
  so 
  abundantly 
  that 
  the 
  window 
  frames 
  and 
  sills 
  may 
  

   become 
  literally 
  covered 
  with 
  wings 
  and 
  bodies 
  of 
  plant 
  lice. 
  It 
  

   is 
  comparatively 
  easy, 
  in 
  a 
  badly 
  infested 
  house, 
  to 
  sweep 
  up 
  a 
  

   gill 
  of 
  wings 
  and 
  exuviae 
  from 
  under 
  one 
  window. 
  This 
  plant 
  

   louse 
  multiplies 
  freely 
  upon 
  the 
  bulbs, 
  usually 
  being 
  massed 
  around 
  

   the 
  origin 
  of 
  the 
  roots 
  and 
  sometimes 
  nearly 
  covering 
  the 
  entire
