  For 
  the 
  destruction 
  of 
  the 
  alfalfa 
  caterpillar 
  (Autographa 
  gamma 
  

   californica, 
  Speyer), 
  renovation 
  of 
  alfalfa 
  fields 
  during 
  the 
  winter 
  

   months 
  is 
  recommended. 
  This 
  will 
  destroy 
  large 
  numbers 
  of 
  the 
  

   hibernating 
  pupae. 
  Pasturing 
  the 
  fields 
  will 
  also 
  aid 
  in 
  the 
  

   destruction 
  of 
  the 
  resting 
  stage 
  of 
  this 
  insect. 
  Among 
  the 
  truck 
  crop 
  

   insects 
  the 
  corn 
  ear 
  worm 
  {ChJoridea 
  ohsoleta) 
  has 
  been 
  reported 
  as 
  

   causing 
  much 
  damage 
  to 
  tomatoes. 
  The 
  use 
  of 
  an 
  early 
  trap 
  crop, 
  

   as 
  well 
  as 
  early 
  maturing 
  varieties, 
  the 
  hand-picking 
  of 
  infested 
  

   tomatoes 
  to 
  prevent 
  the 
  larvae 
  spreading, 
  autumn 
  ploughing 
  of 
  infested 
  

   ground, 
  and 
  the 
  proper 
  disposal 
  of 
  unsaleable 
  infected 
  tomatoes, 
  will 
  

   help 
  in 
  the 
  protection 
  of 
  the 
  next 
  year's 
  crop.

   from

  the

  The 
  eggs 
  of 
  this 
  caterpillar 
  are 
  deposited 
  on 
  the 
  alfalfa 
  leaves, 
  and 
  

   hatch 
  in 
  a 
  few 
  days. 
  The 
  young 
  larvae 
  eat 
  the 
  epidermis 
  of 
  the 
  leaves, 
  

   which 
  soon 
  appear 
  whitish 
  from 
  their 
  attacks, 
  and 
  they 
  web 
  the 
  tops 
  

   of 
  the 
  alfalfa 
  stalks 
  together. 
  In 
  the 
  young 
  stages 
  the 
  larvae 
  work 
  in 
  

   colonies 
  and 
  only 
  on 
  the 
  upper 
  more 
  tender 
  portions 
  of 
  the 
  plant. 
  

   In 
  an 
  alfalfa 
  field 
  at 
  Salt 
  Lake, 
  Utah, 
  it 
  was 
  noted 
  that 
  in 
  the 
  latter 
  

   part 
  of 
  September 
  and 
  in 
  the 
  early 
  days 
  of 
  October 
  w^hen 
  the 
  leaves 
  of 
  

   alfalfa 
  were 
  becoming 
  too 
  tough, 
  the 
  larvae 
  migrated 
  to 
  the 
  edges 
  of 
  

   the 
  field 
  to 
  feed 
  on 
  the 
  tender 
  grow^th 
  of 
  dock. 
  From 
  September 
  to 
  

   October 
  the 
  caterpillars 
  enter 
  the 
  soil 
  to 
  pupate. 
  At 
  present 
  the 
  best 
  

   method 
  of 
  control 
  for 
  this 
  pest 
  is 
  picking 
  and 
  destroying 
  infested 
  tops. 
  

   If 
  the 
  fields 
  are 
  pastured 
  at 
  this 
  time 
  of 
  the 
  year 
  little 
  damage 
  will 
  

   result 
  from 
  this 
  insect's 
  attack. 
  This 
  moth 
  occurs 
  in 
  the 
  Atlantic 
  

   States, 
  Colorado, 
  Utah, 
  and 
  California. 
  It 
  also 
  attacks 
  cabbage, 
  

   celery, 
  beets, 
  and 
  other 
  garden 
  vegetables. 
  A 
  species 
  of 
  Tachinid 
  fly 
  

   and 
  an 
  Ichneumonid 
  (Campoplex) 
  have 
  been 
  reared 
  from 
  M. 
  jncta 
  

   The 
  Campoplex 
  emerges 
  from 
  the 
  larva 
  at 
  about 
  the 
  third 
  stage.
