  This 
  is 
  an 
  official 
  review 
  of 
  the 
  position 
  of 
  crops 
  according 
  to 
  

   information 
  received 
  from 
  8,500 
  local 
  correspondents 
  of 
  the 
  Board 
  

   and 
  contains 
  the 
  following 
  references 
  to 
  harmful 
  insects. 
  Various 
  

   pests 
  appeared 
  in 
  large 
  numbers, 
  but 
  with 
  rare 
  exceptions 
  no 
  serious 
  

   damage 
  was 
  done 
  by 
  them 
  to 
  crops. 
  Species 
  of 
  Phyllotreta 
  caused 
  

   great 
  damage 
  to 
  peas, 
  vetches, 
  lentils, 
  Unseed 
  and 
  hemp 
  seed, 
  also 
  

   to 
  beetroots, 
  cabbage 
  and 
  turnips. 
  On 
  the 
  same 
  plants 
  Curculionidae 
  

   were 
  reported 
  from 
  Tambov, 
  Penza, 
  Nijni 
  Novgorod, 
  Li 
  viand, 
  Perm, 
  

   and 
  the 
  Vistula. 
  In 
  Saratov, 
  lentils, 
  peas 
  and 
  mustard 
  suffered 
  from 
  

   Aphids, 
  which 
  also 
  occurred 
  in 
  the 
  Vistula, 
  Taurida 
  and 
  Tchernigov 
  

   governments 
  on 
  vetches 
  and 
  in 
  orchards. 
  Elaterid 
  larvae 
  did 
  damage 
  

   in 
  many 
  places, 
  especially 
  to 
  summer-sown 
  crops 
  in 
  Li 
  viand 
  and 
  

   Saratov. 
  Anisoplia 
  austriaca 
  has 
  been 
  specially 
  injurious 
  in 
  Poltava, 
  

   Taurida 
  and 
  Astrachan, 
  but 
  also 
  occurred 
  in 
  Tambov, 
  Tula, 
  Voronezh, 
  

   Bessarabia, 
  Cherson, 
  and 
  in 
  the 
  province 
  of 
  the 
  Don. 
  Sawflies 
  were 
  

   reported 
  from 
  Tula, 
  Orel, 
  Taurida, 
  Ekaterinoslav, 
  Poltava, 
  Saratov, 
  

   and 
  in 
  the 
  province 
  of 
  the 
  Don, 
  but 
  did 
  httle 
  damage. 
  In 
  Bessarabia 
  

   and 
  Cherson, 
  oats 
  and 
  wheat 
  suffered 
  considerably 
  from 
  Cecidomyia 
  

   contractor, 
  which 
  was 
  less- 
  injurious 
  in 
  Orel, 
  Voronezh, 
  Kiev, 
  Samara, 
  

   and 
  the 
  Vistula. 
  Oscinis 
  frit, 
  although 
  it 
  appeared 
  in 
  many 
  places, 
  

   did 
  little 
  harm. 
  Thrips 
  occurred 
  only 
  in 
  Voronezh, 
  Samara, 
  Saratov, 
  

   and 
  in 
  the 
  province 
  of 
  the 
  Don, 
  damaging 
  summer-sown 
  wheat 
  and 
  

   rye. 
  Species 
  of 
  Lema 
  are 
  reported 
  in 
  Bessarabia 
  and 
  in 
  the 
  province 
  

   of 
  the 
  Don, 
  and 
  Meligethes 
  aeneus, 
  F., 
  on 
  rape 
  seed 
  in 
  Bessarabia. 
  

   Locusts 
  were 
  observed 
  in 
  Samara, 
  Saratov, 
  Perm, 
  and 
  Orenburg, 
  

   where 
  the 
  outbreak 
  was 
  particularly 
  threatening.
