  them 
  to 
  cut 
  up 
  and 
  burn 
  all 
  dead 
  trees 
  ; 
  but 
  although 
  the 
  natives 
  

   are 
  well 
  aware 
  of 
  the 
  fact 
  that 
  the 
  dead 
  trees 
  are 
  the 
  main 
  breeding: 
  

   grounds 
  of 
  the 
  beetle, 
  very 
  few 
  could 
  be 
  induced 
  to 
  adopt 
  the 
  measures 
  

   recommended. 
  

  

  The 
  beetle 
  has 
  been 
  established 
  in 
  the 
  coast 
  belt 
  for 
  many 
  years, 
  

   but 
  as 
  in 
  Ceylon, 
  it 
  has 
  not 
  spread 
  to 
  anything 
  like 
  the 
  same 
  extent 
  

   as 
  in 
  Samoa, 
  and 
  it 
  is 
  probable 
  that 
  both 
  in 
  this 
  Protectorate 
  and 
  Ceylon 
  

   it 
  has 
  natural 
  enemies, 
  though 
  so 
  far 
  no 
  parasites 
  have 
  been 
  found. 
  

   There 
  is 
  httle 
  doubt, 
  however, 
  that 
  the 
  beetle 
  is 
  gradually, 
  if 
  slowly, 
  

   increasing 
  in 
  numbers. 
  In 
  the 
  trunks 
  of 
  957 
  dead 
  trees 
  no 
  fewer 
  than 
  

   7,650 
  beetles 
  and 
  28,710 
  grubs 
  were 
  found, 
  or 
  an 
  average 
  of 
  eight 
  

   beetles 
  and 
  thirty 
  grubs 
  from 
  each 
  tree. 
  It 
  is 
  estimated 
  that 
  2 
  per 
  

   cent, 
  of 
  the 
  coconut 
  trees 
  (including 
  trunks 
  lying 
  on 
  the 
  ground) 
  are 
  

   dead, 
  and 
  in 
  view 
  of 
  the 
  indifference 
  of 
  the 
  natives 
  it 
  will 
  be 
  necessary 
  

   to 
  introduce 
  compulsory 
  legislation 
  to 
  deal 
  with 
  the 
  matter.

  The 
  work 
  of 
  the 
  department 
  has 
  been 
  practically 
  confined 
  during 
  

   the 
  year 
  to 
  fruit 
  fhes 
  of 
  the 
  genus 
  Dacus. 
  

  

  A 
  poison-spray 
  method, 
  which 
  depends 
  for 
  its 
  efficacy 
  on 
  the 
  habit 
  

   of 
  the 
  peach 
  fly 
  (D. 
  zonatus) 
  of 
  sucking 
  tentatively 
  at 
  any 
  Httle 
  drop 
  

   of 
  moisture 
  on 
  a 
  leaf, 
  was 
  tried 
  with 
  excellent 
  results. 
  The 
  proportion 
  

   of 
  affected 
  peaches 
  in 
  the 
  sprayed 
  plots 
  was 
  approximately 
  2 
  per 
  cent, 
  

   over 
  the 
  whole 
  period 
  of 
  picking, 
  in 
  place 
  of 
  the 
  usual 
  45-60 
  per 
  cent. 
  

   The 
  cost 
  of 
  the 
  method 
  is 
  very 
  small 
  compared 
  with 
  the 
  value 
  of 
  the 
  

   crop, 
  and 
  should 
  this 
  year's 
  results 
  be 
  confirmed 
  by 
  another 
  season's 
  

   work, 
  they 
  will 
  have 
  a 
  very 
  considerable 
  commercial 
  importance. 
  

  

  It 
  has 
  been 
  found 
  that 
  these 
  insects 
  are 
  strongly 
  attracted 
  by 
  

   certain 
  compounds 
  alhed 
  to 
  Eugenol 
  (CioHi._j0.2), 
  and 
  this 
  substance 
  

   constituted 
  a 
  means 
  of 
  detecting 
  the 
  presence 
  of 
  the 
  fruit 
  flies 
  in 
  a 
  

   given 
  locaUty 
  with 
  a 
  certainty 
  quite 
  unattainable 
  by 
  any 
  ordinary 
  

   method 
  of 
  observation. 
  

  

  The 
  author 
  discovered 
  by 
  this 
  means 
  that 
  the 
  north-western 
  limit 
  

   of 
  the 
  distribution 
  of 
  the 
  peach 
  fly 
  practically 
  corresponds 
  with 
  the 
  

   south-eastern 
  limit 
  of 
  successful 
  peach-growing. 
  

  

  It 
  has 
  been 
  shown 
  by 
  Mr. 
  and 
  Mrs. 
  Howard 
  that 
  it 
  is 
  possible 
  to 
  

   grow 
  peaches 
  of 
  the 
  first 
  quahty 
  at 
  Pusa, 
  and 
  the 
  author 
  says 
  that, 
  in 
  

   his 
  opinion, 
  the 
  reason 
  why 
  peaches 
  are 
  not 
  largely 
  or 
  profitably 
  grown 
  

   in 
  the 
  southern 
  and 
  eastern 
  portions 
  of 
  the 
  Gangetic 
  Plain 
  and 
  in 
  

   various 
  districts 
  in 
  Southern 
  India 
  is 
  largely 
  or 
  entirely 
  due 
  to 
  the 
  

   prevalence 
  of 
  peach 
  fly, 
  50 
  per 
  cent, 
  or 
  more 
  of 
  the 
  crop 
  being 
  invariably 
  

   maggoty. 
  The 
  successful 
  apphcation 
  of 
  the 
  poison-spray 
  method 
  may 
  

   therefore 
  possibly 
  result 
  in 
  the 
  opening 
  up 
  of 
  large 
  areas 
  of 
  profitable 
  

   cultivation.
