  This 
  is 
  a 
  popular 
  account 
  of 
  damage 
  done 
  to 
  crops 
  by 
  caterpillars 
  of 
  

   Oria 
  (Tapinostola) 
  musculosa. 
  This 
  is 
  the 
  most 
  serious 
  pest 
  of 
  grain- 
  

   crops 
  in 
  South 
  Russia, 
  and 
  in 
  one 
  district 
  of 
  the 
  province 
  of 
  Don 
  

   2,700 
  acres 
  of 
  crops 
  were 
  damaged, 
  of 
  which 
  810 
  acres 
  were 
  totally- 
  

   destroyed. 
  The 
  females 
  are 
  on 
  the 
  wing 
  during 
  July 
  and 
  August, 
  

   and 
  oviposit 
  on 
  the 
  stems 
  of 
  grasses 
  or 
  on 
  the 
  stubble 
  of 
  grain-crops 
  ; 
  

   the 
  eggs 
  remain 
  over 
  the 
  winter 
  and 
  the 
  caterpillars 
  hatch 
  early 
  in 
  

   the 
  spring. 
  The 
  larvae 
  enter 
  the 
  stems 
  of 
  grain 
  through 
  a 
  minute 
  

   hole 
  bored 
  close 
  to 
  the 
  earth. 
  Before 
  pupation 
  they 
  gnaw 
  through 
  

   the 
  base 
  of 
  the 
  ear. 
  Preventive 
  measures 
  include 
  the 
  cultivation 
  of 
  

   strains 
  proof 
  against 
  the 
  pests, 
  rotation 
  of 
  crops, 
  careful 
  removal 
  and 
  

   destruction 
  of 
  all 
  weeds, 
  deep-ploughing, 
  and 
  burning 
  of 
  stubble 
  and 
  

   rubbish 
  after 
  the 
  harvest.
