  Station 
  in 
  1913, 
  a 
  programme 
  intended 
  to 
  be 
  carried 
  out 
  in 
  1914 
  and 
  

   some 
  estimates 
  for 
  1915. 
  There 
  is 
  an 
  Entomological 
  Section 
  at 
  the 
  

   Station, 
  a 
  report 
  of 
  which 
  is 
  also 
  included. 
  

  

  The 
  chief 
  pest 
  of 
  orchards 
  is 
  Schizoneura 
  lanigera, 
  Hausm., 
  control 
  

   of 
  which 
  is 
  conducted 
  only 
  in 
  the 
  nurseries 
  ; 
  the 
  local 
  variety 
  of 
  

   apple 
  called 
  '' 
  Abchaz-apple 
  " 
  is 
  not 
  attacked 
  or 
  only 
  httle 
  injured 
  

   by 
  this 
  pest. 
  

  

  Cydia 
  pomonella 
  and 
  Rhynchites 
  pauxillus, 
  Germ., 
  occur 
  everywhere 
  

   and 
  are 
  very 
  injurious. 
  Other 
  pests 
  include 
  Thrips, 
  on 
  various 
  nursery 
  

   plants 
  ; 
  Lachnus 
  persicae, 
  on 
  peaches, 
  which 
  however 
  does 
  not 
  do 
  

   serious 
  damage, 
  even 
  when 
  present 
  in 
  large 
  numbers 
  ; 
  Lepidosaphes 
  

   ulmi 
  {Mytilaspis 
  jjomorum), 
  and 
  other 
  Coccidae 
  ; 
  Zeuzera 
  aesculi, 
  

   Vanessa 
  polychloros, 
  Lymantria 
  {Ocneria) 
  dispar, 
  and 
  some 
  species 
  of 
  

   ToRTRiciDAE 
  and 
  of 
  ScoLYTiDAE. 
  Among 
  market-gardens 
  pests 
  

   the 
  report 
  mentions 
  : 
  Pieris 
  brassicae, 
  PhUella 
  maculipennis, 
  Curt. 
  

   fcruciferarum, 
  ZelL), 
  Athalia 
  spinarum, 
  F., 
  and 
  some 
  Halticini. 
  

  

  Pyrausta 
  nuhilalis 
  (Botys 
  silacealis, 
  Hb.), 
  and 
  P. 
  quadripuncialis 
  , 
  

   Schiff., 
  are 
  injurious 
  to 
  maize, 
  the 
  infection 
  of 
  cobs 
  and 
  stalks 
  of 
  this 
  

   plant 
  in 
  some 
  localities 
  amounting 
  to 
  50 
  per 
  cent. 
  SiphoyiopJiora 
  

   scabiosae, 
  Buckt., 
  and 
  Thrips 
  are 
  pests 
  of 
  tobacco. 
  Grain 
  stores 
  

   are 
  injured 
  by 
  Tinea 
  granella, 
  L., 
  and 
  by 
  Calandra 
  granaria, 
  L., 
  which 
  

   are 
  both 
  important 
  pests 
  in 
  this 
  district. 
  Insect 
  pests 
  in 
  Suchum 
  

   are 
  numerous 
  and 
  the 
  gradual 
  study 
  of 
  their 
  biology 
  will, 
  it 
  is 
  hoped, 
  

   enable 
  the 
  best 
  methods 
  of 
  controlling 
  them 
  to 
  be 
  discovered. 
  

  

  During 
  the 
  current 
  year 
  it 
  is 
  intended 
  to 
  study 
  especially 
  the 
  biology 
  

   and 
  control 
  of 
  Schizoneura 
  lanigera, 
  Hausm., 
  Coccidae, 
  Athalia 
  

   spinarum, 
  F., 
  Cydia 
  pomonella, 
  and 
  some 
  others 
  of 
  the 
  previously 
  

   mentioned 
  pests. 
  Spraying 
  experiments 
  and 
  the 
  collection 
  of 
  

   entomological 
  specimens 
  will 
  also 
  be 
  undertaken.

  The 
  application 
  of 
  iron-sulphate 
  is 
  recommended 
  in 
  this 
  article, 
  

   chiefly 
  in 
  order 
  to 
  destroy 
  moss 
  and 
  lichen 
  on 
  trees, 
  but 
  also 
  as 
  a 
  

   remedy 
  against 
  Psylla 
  mali. 
  For 
  the 
  latter 
  purpose 
  a 
  3 
  per 
  cent, 
  

   solution 
  (1 
  lb. 
  of 
  iron 
  sulphate 
  in 
  11 
  quarts 
  of 
  water) 
  is 
  recommended 
  

   to 
  be 
  sprayed 
  before 
  the 
  buds 
  swell. 
  This 
  remedy 
  does 
  not, 
  however, 
  

   always 
  lead 
  to 
  a 
  total 
  destruction 
  of 
  the 
  eggs 
  of 
  this 
  pest, 
  and

  further
