  The 
  author 
  has 
  conducted 
  a 
  campaign 
  against 
  Schizoneura 
  lanigera 
  

   in 
  the 
  orchards 
  in 
  the 
  district 
  of 
  Tashkent, 
  organised 
  by 
  the 
  Ento- 
  

   mological 
  Station 
  of 
  Turkestan. 
  This 
  pest 
  has 
  but 
  comparatively 
  

   recently 
  appeared 
  in 
  Turkestan, 
  but 
  has 
  nevertheless 
  spread 
  over 
  

   considerable 
  areas, 
  and 
  in 
  the 
  above 
  orchards 
  at 
  least 
  20 
  per 
  cent, 
  of 
  

   the 
  trees 
  are 
  infested. 
  Spraying 
  was 
  undertaken 
  with 
  quassia 
  

   emulsion,kerosene 
  hme 
  emulsion, 
  and 
  tobacco 
  extract, 
  and 
  the 
  trees 
  were 
  

   smeared 
  with 
  fat. 
  The 
  mode 
  of 
  preparation 
  of 
  the 
  insecticides 
  was 
  as 
  

   follows 
  : 
  — 
  (1) 
  For 
  quassia 
  emulsion 
  : 
  30 
  lb. 
  of 
  quassia 
  chips 
  were 
  

   boiled 
  in 
  about 
  27 
  gals, 
  of 
  water 
  for 
  2 
  to 
  3 
  hours, 
  the 
  decoction 
  being 
  

   afterwards 
  strained 
  and 
  mixed 
  with 
  20 
  lb. 
  of 
  green 
  soap, 
  dissolved 
  

   in 
  warm, 
  soft 
  water 
  ; 
  the 
  whole 
  was 
  then 
  made 
  up 
  with 
  water 
  to 
  a 
  

   total 
  volume 
  of 
  210-240 
  gals. 
  (2) 
  For 
  kerosene-hme 
  emulsion 
  : 
  Milk 
  

   of 
  Hme 
  prepared 
  from 
  about 
  2 
  oz. 
  of 
  lump 
  lime 
  is 
  mixed 
  with 
  3 
  lb. 
  of 
  

   kerosene, 
  after 
  which 
  the 
  mixture 
  is 
  emulsified 
  with 
  a 
  small 
  bundle 
  

   of 
  twigs 
  ; 
  water 
  is 
  added 
  to 
  make 
  up 
  2f 
  gals, 
  of 
  the 
  mixture, 
  after 
  

   which 
  it 
  is 
  again 
  well 
  stirred. 
  (3) 
  For 
  tobacco 
  extract, 
  1 
  lb. 
  of 
  Pastack's 
  

   extract 
  and 
  ^ 
  lb. 
  of 
  green 
  soap 
  are 
  dissolved 
  in 
  2| 
  gals, 
  of 
  water. 
  The 
  

   spraying 
  with 
  all 
  these 
  insecticides 
  must 
  be 
  repeated 
  after 
  12 
  hours, 
  

   in 
  order 
  to 
  ensure 
  the 
  total 
  destruction 
  of 
  small 
  colonies 
  of 
  Hce, 
  which 
  

   may 
  be 
  sheltered 
  in 
  the 
  foliage. 
  Owing 
  to 
  the 
  great 
  heat 
  prevailing, 
  

   the 
  spraying 
  was 
  done 
  from 
  5 
  to 
  9 
  a.m. 
  and 
  from 
  4 
  to 
  4.30 
  p.m. 
  

   Tobacco 
  extract 
  in 
  the 
  above 
  proportion 
  caused 
  scorching 
  of 
  the 
  

   foliage, 
  while 
  a 
  weaker 
  solution 
  was 
  less 
  effective, 
  and 
  this 
  insecticide 
  

   was 
  therefore 
  not 
  further 
  used 
  ; 
  the 
  other 
  insecticides 
  caused 
  no 
  

   scorching. 
  Smearing 
  all 
  the 
  branches 
  and 
  the 
  trunks 
  of 
  the 
  trees 
  

   with 
  grease 
  was 
  very 
  effective 
  ; 
  it 
  must 
  be 
  done 
  in 
  spring 
  before 
  the 
  

   unfolding 
  of 
  the 
  buds, 
  or 
  in 
  autumn 
  after 
  the 
  leaves 
  have 
  fallen.

  In 
  May 
  1914, 
  it 
  was 
  reported 
  that 
  a 
  lepidopterous 
  insect 
  was 
  

   seriously 
  injuring 
  some 
  young 
  Scotch 
  pines 
  in 
  Long 
  Island. 
  The 
  

   insect 
  proved 
  to 
  be 
  Rhyacionia 
  (Evetria) 
  buoliana, 
  which 
  has 
  hitherto 
  

   not 
  been 
  reported 
  from 
  America, 
  but 
  which 
  does 
  considerable 
  

   damage 
  to 
  the 
  pines 
  of 
  Europe 
  and 
  also 
  occurs 
  in 
  Siberia. 
  It 
  is 
  

   generally 
  recognised 
  as 
  the 
  most 
  injurious 
  insect 
  to 
  Pinus 
  sylvestris 
  

   and 
  other 
  pines, 
  and 
  its 
  occurrence 
  in 
  Long 
  Island 
  is 
  therefore 
  of 
  con- 
  

   siderable 
  importance. 
  The 
  eggs 
  are

  buds 
  of

  late
