  Phlydaenodes 
  sticticalis, 
  L. 
  , 
  appears 
  yearly, 
  doing 
  more 
  or 
  less 
  damage. 
  

   Last 
  year 
  the 
  caterpillars 
  in 
  some 
  parts 
  totally 
  devoured 
  the 
  sun- 
  

   flowers, 
  maize, 
  pumpkins, 
  melons 
  and 
  cucumbers. 
  The 
  caterpillars 
  

   of 
  Homoeosoma 
  nebulella, 
  Hb., 
  do 
  considerable 
  damage 
  to 
  sunflower 
  

   seeds. 
  Plusia 
  gamma, 
  L., 
  injures 
  many 
  cultivated 
  plants, 
  principally 
  

   beets 
  and 
  linseed, 
  but 
  last 
  year 
  there 
  were 
  practically 
  no 
  complaints 
  

   of 
  its 
  activity. 
  

  

  Lema 
  melanopa, 
  L., 
  has 
  done 
  considerable 
  damage 
  to 
  oats, 
  barley, 
  

   and 
  summer-sown 
  wheat, 
  during 
  the 
  latter 
  half 
  of 
  June 
  and 
  the 
  

   beginning 
  of 
  July. 
  As 
  remedies 
  are 
  recommended 
  : 
  (1) 
  shaking 
  the 
  

   insects 
  off 
  the 
  oats 
  with 
  brooms 
  in 
  the 
  mornings, 
  after 
  which 
  the 
  

   attacked 
  spots 
  must 
  be 
  dusted 
  wdth 
  ashes 
  or 
  lime 
  through 
  a 
  sieve 
  ; 
  

   (2) 
  the 
  spraying 
  of 
  three 
  per 
  cent, 
  solution 
  in 
  water 
  of 
  barium 
  chloride 
  

   or 
  Paris 
  green 
  (I 
  oz. 
  green 
  and 
  3 
  oz. 
  freshly 
  slaked 
  lime 
  in 
  6 
  gals, 
  

   water) 
  ; 
  (3) 
  summer 
  sowing 
  instead 
  of 
  winter 
  sowing, 
  or 
  the 
  earlier 
  

   sowing 
  of 
  summer 
  crops. 
  Psylliodes 
  attenuatus, 
  Koch, 
  Chaetocnema 
  

   concinna, 
  Chevr., 
  and 
  P. 
  hreviuscida, 
  Fald., 
  have 
  damaged 
  hemp 
  seeds 
  

   and 
  beets. 
  As 
  a 
  remedy 
  " 
  a 
  tanelefoot 
  cart 
  " 
  is 
  suggested, 
  consisting 
  

   of 
  a 
  board 
  on 
  wheels, 
  smeared 
  on 
  the 
  lower 
  side 
  with 
  molasses 
  or 
  pitch, 
  

   to 
  be 
  wheeled 
  over 
  the 
  plants 
  during 
  the 
  hot 
  hours 
  of 
  the 
  day, 
  so 
  as 
  to 
  

   catch 
  the 
  insects 
  when 
  they 
  jump. 
  

  

  Calandra 
  granaria, 
  L. 
  In 
  an 
  appendix 
  to 
  the 
  report 
  the 
  campaign 
  

   against 
  this 
  pest 
  in 
  the 
  municipal 
  grain 
  stores 
  of 
  Voronezh 
  is 
  described. 
  

   Carbon 
  bisulphide 
  has 
  been 
  used 
  successfully, 
  and 
  it 
  has 
  been 
  noticed 
  

   that 
  this 
  remedy 
  gives 
  better 
  results 
  in 
  warm 
  w^eather 
  than 
  during 
  

   cold 
  or 
  windy 
  weather. 
  The 
  germinating 
  capacity 
  of 
  the 
  grain 
  is 
  not 
  

   affected 
  if 
  the 
  proportions 
  do 
  not 
  exceed 
  about 
  1 
  lb. 
  of 
  bisulphide 
  for 
  

   each 
  ton 
  of 
  grain. 
  Lethrus 
  apterus, 
  Laxm., 
  damages 
  various 
  young 
  

   plants, 
  and 
  particularly 
  sown 
  sunflower 
  seeds. 
  The 
  following 
  remedies 
  

   are 
  given 
  : 
  (1) 
  trenches 
  round 
  the 
  plantation 
  ; 
  (2) 
  spraying 
  mth 
  Paris 
  

   green 
  ; 
  (3) 
  ploughing 
  the 
  infected 
  plots 
  in 
  autumn 
  or 
  early 
  spring, 
  

   and 
  keeping 
  them 
  clear 
  from 
  w^eeds 
  to 
  the 
  end 
  of 
  May 
  ; 
  (4) 
  hand- 
  

   picking. 
  

  

  Anisoplia 
  austriaca, 
  Hbst., 
  is 
  very 
  widespread 
  in 
  the 
  Government. 
  

   The 
  usual 
  remedy 
  consists 
  in 
  hand-picking, 
  the 
  insects 
  being 
  driven 
  

   by 
  a 
  rope 
  to 
  one 
  end 
  of 
  the 
  field, 
  where 
  they 
  are 
  at 
  once 
  picked 
  up 
  by 
  

   men 
  with 
  sacks. 
  The 
  Zemstvo 
  pays 
  a 
  premium 
  for 
  the 
  collection 
  of 
  

   this 
  insect, 
  and 
  the 
  author 
  suggests 
  that 
  this 
  ought 
  to 
  be 
  encouraged 
  

   and 
  properly 
  organised. 
  The 
  insect 
  usually 
  begins 
  by 
  damaging 
  the 
  

   ears 
  of 
  winter-grow^n 
  crops, 
  passing 
  afterwards 
  to 
  barley 
  and 
  summer- 
  

   sown 
  wheat. 
  The 
  beetles 
  oviposit 
  in 
  July 
  on 
  the 
  borders 
  of 
  the 
  fields, 
  

   so 
  that 
  the 
  ploughing 
  of 
  these 
  parts 
  in 
  August 
  would 
  lead 
  to 
  the 
  

   destruction 
  of 
  the 
  eggs 
  and 
  of 
  the 
  young 
  larvae. 
  

  

  Mayetiola 
  (Cecidomyia) 
  destructor, 
  Say, 
  is 
  a 
  serious 
  pest 
  of 
  grain, 
  

   and 
  is 
  found 
  everywhere 
  in 
  the 
  Government. 
  The 
  remedies 
  usually 
  

   applied 
  are 
  ploughing, 
  burning 
  of 
  the 
  stubbles 
  and 
  trap-crops. 
  

  

  The 
  larvae 
  of 
  Bibio 
  hortulanus, 
  L., 
  damaged 
  sugar-beets 
  in 
  one 
  

   locality 
  ; 
  as 
  remedies 
  are 
  suggested 
  : 
  the 
  complete 
  removal 
  of 
  the
