  During 
  the 
  year 
  under 
  review 
  there 
  was 
  no 
  serious 
  outbreak 
  of 
  any 
  

   insect 
  pest, 
  although 
  new 
  ones 
  have 
  been 
  met 
  with, 
  and 
  the 
  old 
  ones 
  have 
  

   been 
  more 
  or 
  less 
  abundant. 
  AVhite 
  grubs 
  were 
  reported 
  to 
  be 
  doing 
  

   more 
  damage 
  than 
  hitherto, 
  crops 
  on 
  badly 
  cultivated 
  land 
  being 
  most 
  

   affected. 
  The 
  woolly 
  apple 
  aphis 
  (Eriosoma 
  lanigerum) 
  has 
  been 
  found 
  

   in 
  new 
  localities, 
  and 
  in 
  spite 
  of 
  the 
  inspection 
  of 
  imported 
  trees 
  it 
  

   has 
  been 
  again 
  introduced 
  into 
  the 
  country. 
  Cut 
  worms 
  in 
  nursery 
  

   beds 
  have 
  been 
  destructive, 
  especially 
  in 
  the 
  case 
  of 
  tobacco. 
  Numerous 
  

   bugs 
  and 
  borers 
  have 
  been 
  found 
  on 
  the 
  coffee 
  plantations. 
  A 
  study 
  

   of 
  these 
  was 
  made, 
  as 
  the 
  coffee 
  industry 
  is 
  likely 
  to 
  be 
  one 
  of 
  some 
  

   magnitude. 
  Maize 
  to 
  the 
  amount 
  of 
  9,866 
  tons 
  was 
  passed 
  for 
  export, 
  

   of 
  which 
  628 
  tons 
  were 
  passed 
  through 
  the 
  fumigating 
  chambers.

  The 
  author 
  opens 
  with 
  a 
  general 
  statement 
  that 
  on 
  the 
  whole. 
  

   Agriculture 
  in 
  Russia 
  suffered 
  in 
  1912 
  considerably 
  from 
  various 
  insect 
  

   pests. 
  In 
  Asiatic 
  Russia, 
  and 
  also 
  in 
  some 
  eastern 
  and 
  south-eastern 
  

   governments 
  of 
  European 
  Russia, 
  there 
  were 
  outbreaks 
  of 
  various 
  

   species 
  of 
  locusts, 
  which 
  have 
  invaded 
  even 
  the 
  province 
  of 
  the 
  Don 
  

   and 
  some 
  parts 
  of 
  the 
  government 
  of 
  Taurida, 
  where 
  Caloptenus 
  

   italicus, 
  L., 
  has 
  appeared 
  in 
  great 
  numbers. 
  In 
  the 
  north 
  and 
  also 
  

   in 
  some 
  parts 
  of 
  Middle 
  Russia, 
  the 
  chief 
  pest 
  was 
  Euxoa 
  (Agrotis) 
  

   segetum, 
  Schiff. 
  It 
  has 
  been 
  observed 
  that 
  these 
  insects 
  do 
  not 
  attack 
  

   fields 
  on 
  which 
  vetches 
  have 
  grown 
  during 
  the 
  summer 
  ; 
  the 
  actual 
  

   reason 
  of 
  this 
  is 
  not 
  yet 
  known 
  and 
  requires 
  further 
  investigation. 
  

   Vetches 
  have 
  also 
  proved 
  very 
  useful 
  in 
  combating 
  another 
  grass 
  pest 
  

   in 
  North 
  Russia, 
  viz., 
  Chareas 
  graminis, 
  which, 
  in 
  1912, 
  totally 
  

   destroyed 
  the 
  grazing 
  in 
  the 
  district 
  of 
  Jamburg, 
  of 
  the 
  government 
  of 
  

   St. 
  Petersburg. 
  Agrotis 
  c-nigrum, 
  which 
  has 
  been 
  considered 
  to 
  be 
  

   little 
  injurious, 
  has 
  done 
  damage 
  in 
  the 
  government 
  of 
  Vjatka, 
  where 
  

   its 
  caterpillars 
  appeared 
  in 
  the 
  first 
  half 
  of 
  May 
  on 
  winter-sown 
  fields, 
  

   feeding 
  first 
  on 
  weeds 
  and 
  later 
  on 
  the 
  crops. 
  In 
  South 
  Russia 
  

   considerable 
  damage 
  was 
  done 
  by 
  Oria 
  {Tapinostola) 
  musculosa 
  in 
  the 
  

   government 
  of 
  Ekaterinoslav. 
  These 
  pests 
  have 
  done 
  more 
  or 
  less 
  

   damage 
  to 
  nearly 
  45,000 
  dessiatines 
  (120,000 
  acres) 
  of 
  crops, 
  the 
  loss
