  NOTE 
  ON 
  SUGARCANE 
  BORERS 
  IN 
  THE 
  CENTRAL 
  PRO- 
  

   VINCES. 
  

  

  By 
  J. 
  L. 
  Khare, 
  B.A., 
  F.E.S., 
  Lecturer 
  in 
  Entomology 
  at 
  the 
  Nagpur 
  

  

  Agricultural 
  College. 
  

  

  This 
  preliminary 
  note 
  has 
  been 
  drawn 
  up 
  principally 
  with 
  an 
  idea 
  

   of 
  collating 
  the 
  results 
  of 
  some 
  experiments 
  on 
  sugarcane 
  borers, 
  which 
  

   have 
  been 
  conducted 
  at 
  the 
  difEerent 
  experimental 
  stations 
  in 
  this 
  

   Province. 
  The 
  experimental 
  part 
  of 
  the 
  work 
  was 
  carried 
  by 
  the 
  late 
  

   Entomological 
  Assistant, 
  Mr. 
  Ratiram 
  Khamparia, 
  who 
  was 
  in 
  charge 
  

   of 
  field 
  work 
  and 
  thus 
  had 
  opportunities 
  of 
  visiting 
  different 
  farms 
  

   to 
  carry 
  on 
  the 
  experiments. 
  The 
  Writer 
  of 
  this 
  note 
  undertook 
  the 
  

   survey 
  of 
  different 
  species 
  of 
  borers. 
  Attached 
  as 
  he 
  is 
  to 
  the 
  College, 
  

   it 
  was 
  not 
  possible 
  for 
  him 
  to 
  go 
  out 
  personally 
  to 
  collect 
  specimens 
  

   and 
  to 
  determine 
  the 
  percentage 
  of 
  loss. 
  He 
  has, 
  however, 
  collected 
  

   information 
  and 
  samples 
  from 
  the 
  Superintendents 
  and 
  the 
  Agricul- 
  

   tural 
  Assistant 
  stationed 
  in 
  the 
  cane-growing 
  tracts. 
  The 
  tables 
  

   of 
  the 
  distribution 
  of 
  the 
  species 
  of 
  borers 
  and 
  the 
  approximate 
  damage 
  

   caused 
  by 
  them 
  are 
  given 
  at 
  the 
  end 
  of 
  this 
  note. 
  

  

  Before 
  giving 
  a 
  brief 
  resume 
  of 
  the 
  past 
  work 
  on 
  borers, 
  it 
  is 
  desirable 
  

   to 
  examine 
  the 
  position 
  of 
  the 
  Central 
  Provinces 
  as 
  a 
  whole 
  and 
  in 
  

   relation 
  to 
  the 
  rest 
  of 
  British 
  India 
  with 
  regard 
  to 
  the 
  extent 
  of 
  cane 
  

   cultivation. 
  According 
  to 
  the 
  latest 
  agricultural 
  statistics 
  available, 
  

   the 
  area 
  under 
  sugarcane 
  in 
  this 
  Province 
  was 
  24,798 
  acres 
  in 
  1917-18, 
  

   thus 
  being 
  only 
  0-28 
  per 
  cent, 
  of 
  the 
  total 
  area 
  in 
  the 
  whole 
  of 
  British 
  

   India, 
  which 
  was 
  2,808,204 
  acres. 
  In 
  the 
  Central 
  Provinces 
  sugarcane 
  

   cultivation 
  is 
  carried 
  on 
  practically 
  in 
  all 
  the 
  districts, 
  the 
  largest 
  area 
  

   being 
  in 
  the 
  Bilaspur 
  district 
  and 
  the 
  least 
  in 
  Nimar. 
  The 
  distributon 
  

   of 
  the 
  area 
  can 
  be 
  well 
  seen 
  from 
  the 
  statement 
  given 
  below
