   On 
  some

  as 
  many 
  as 
  270

  were 
  found,

  the

  threat- 
  

   ened 
  to

  suggests 
  spraying 
  

   the 
  plants 
  with 
  Paris 
  green, 
  repeating 
  the 
  spraying 
  later 
  when 
  the 
  

   ovaries 
  are 
  well 
  formed. 
  The 
  insecticide 
  must 
  be 
  used 
  in 
  a 
  propor- 
  

   tion 
  of 
  1 
  oz. 
  of 
  green 
  and 
  2

  Government 
  larvae 
  of 
  a 
  Galerucid 
  beetle, 
  

   Leptosonyx 
  silphoides, 
  appeared, 
  moving 
  in 
  large 
  numbers 
  over 
  the 
  

   steppes, 
  after 
  the 
  manner 
  of 
  Phlyctaenodes 
  sticticalis 
  ; 
  the 
  author 
  is, 
  

   however, 
  of 
  opinion 
  that 
  this 
  insect 
  feeds 
  only 
  on 
  wormwood, 
  not 
  

   touching 
  cultivated 
  plants. 
  

  

  Recipes 
  are 
  given 
  for 
  one 
  insecticide 
  and 
  two 
  fungicides. 
  The 
  

   insecticide 
  is 
  recommended 
  against 
  pests 
  of 
  the 
  vine, 
  and 
  consists 
  of 
  

   a 
  solution

  with 
  which 
  the 
  

   young 
  buds 
  are 
  to 
  be 
  sprayed 
  in 
  early 
  spring.

  The 
  southern 
  parts 
  of 
  the 
  Government 
  of 
  Astrachan, 
  along 
  the 
  

   banks 
  of 
  the 
  Volga 
  and 
  of 
  the 
  Caspian 
  Sea 
  are 
  most 
  suitable 
  places 
  

   for 
  the 
  breeding 
  of 
  Asiatic 
  locusts 
  (Locusta 
  migratoria 
  and 
  L. 
  danica) 
  ; 
  

   the 
  coasts 
  are 
  covered 
  with 
  reeds, 
  there 
  being 
  also 
  various 
  meadow 
  

   plants, 
  and 
  the 
  soil 
  is 
  suitable 
  for 
  the 
  oviposition 
  of 
  .these 
  insects. 
  

   The 
  people 
  in 
  these 
  parts 
  are 
  mostly 
  fishermen, 
  and, 
  therefore, 
  the 
  

   damage 
  done 
  by 
  the 
  pests 
  is 
  usually 
  disregarded, 
  the 
  locusts 
  appear- 
  

   ing 
  every 
  year 
  without 
  exception. 
  Oviposition 
  takes 
  place 
  at 
  the 
  

   end 
  of 
  August 
  and 
  during 
  September 
  on 
  friable, 
  sandy 
  or 
  loamy 
  soil, 
  

   and 
  the 
  hatching 
  begins 
  in 
  May. 
  The 
  spring 
  floods 
  of 
  the 
  Volga 
  

   destroy 
  large 
  numbers 
  of 
  eggs, 
  and 
  the 
  author 
  is 
  of 
  opinion 
  that 
  if 
  

   this 
  were 
  not 
  the 
  case, 
  the 
  locusts 
  would 
  become 
  so 
  numerous 
  as 
  to 
  

   threaten 
  even 
  many 
  central 
  Governments 
  of 
  Russia. 
  

  

  The 
  following 
  parasites 
  of 
  locusts 
  are 
  mentioned 
  : 
  — 
  Sarcophaga 
  

   lineata, 
  Fall., 
  which 
  mostly 
  parasitises 
  the 
  larvae, 
  and 
  another 
  fly 
  of 
  the 
  

   genus 
  Anthomyia, 
  which 
  attacks 
  the 
  winged 
  insects. 
  Besides 
  these 
  

   flies, 
  the 
  following 
  insects 
  prey 
  on 
  the 
  eggs 
  of 
  the 
  locusts 
  : 
  — 
  Epicauta 
  

   erythrocephala 
  v. 
  latelineolata, 
  Mylabris 
  calida, 
  and 
  the 
  larvae 
  of 
  flies 
  

   of 
  the 
  genus 
  Systoechus 
  ; 
  the 
  latter 
  being 
  found 
  by 
  the 
  author 
  in 
  

   20-25 
  per 
  cent, 
  of 
  the 
  egg-clusters. 
  

  

  The 
  difficulties 
  in 
  combating 
  the 
  insects 
  are 
  considerable, 
  owing 
  to 
  

   the 
  situation 
  of 
  the 
  breeding 
  places 
  among 
  flooded 
  reeds, 
  and 
  the 
  lack 
  

   of 
  workmen 
  on 
  the 
  spot, 
  etc. 
  The 
  method 
  adopted 
  was 
  spraying 
  with 
  

   Paris 
  green 
  (1 
  lb. 
  of 
  green, 
  4 
  lb. 
  of 
  milk 
  of 
  lime, 
  and 
  2 
  lb. 
  of 
  a 
  special 
  

   glue, 
  in 
  about 
  14 
  gallons 
  of 
  water) 
  ; 
  for 
  the 
  later 
  larval 
  stages 
  the 
  

   insecticide 
  was 
  made 
  even 
  stronger.
