  it

  several 
  fields 
  were 
  

   visited 
  and 
  every 
  leaf 
  in 
  the 
  fields 
  examined 
  was 
  attacked 
  by 
  the 
  thrips. 
  The 
  

   alfalfa 
  has 
  a 
  whitish 
  and 
  bleached 
  appearance, 
  due 
  to 
  the 
  effects 
  of 
  the 
  thrips' 
  

   feeding. 
  I 
  never 
  saw 
  anything 
  to 
  equal 
  this 
  in 
  appearance 
  or 
  in 
  thoroughness

  September 
  .".<> 
  the 
  fields 
  were 
  still 
  being 
  badly 
  damaged. 
  After 
  a 
  

   field 
  is 
  newly 
  irrigated 
  lust 
  after 
  cutting 
  for 
  a 
  week 
  or 
  10 
  days 
  the 
  damage 
  is 
  

  

  not 
  Doticeable, 
  but 
  after 
  three 
  weeks 
  nearly 
  all 
  leaves 
  show 
  the 
  effects 
  and 
  the 
  

  

  alfalfa 
  presents 
  a 
  very 
  sickly 
  appearance. 
  A 
  lack 
  of 
  sutiieient 
  water 
  causes 
  

   the 
  damage 
  to 
  ho 
  more 
  ooticeable, 
  as 
  under 
  such 
  a 
  condition 
  the 
  growth 
  of 
  the 
  

   alfalfti 
  is 
  not 
  so 
  rapid 
  and 
  the 
  thrips' 
  damage 
  is 
  more 
  conspicuous.
