  PROCEEDINGS

  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  

  

  not 
  in 
  the 
  cotton 
  crop 
  but 
  in 
  two 
  species 
  of 
  Ahutilon 
  which 
  are 
  common 
  

   weeds 
  in 
  the 
  cotton 
  fields. 
  

  

  Examination 
  of 
  large 
  numbers 
  of 
  bolls 
  from 
  several 
  Cambodia 
  cotton 
  

   tracts 
  and 
  also 
  from 
  districts 
  where 
  " 
  country 
  " 
  cottons 
  were 
  grown, 
  

   bore 
  out 
  the 
  observation 
  that 
  Farias 
  is 
  not 
  as 
  a 
  rule 
  a 
  serious 
  pest 
  during 
  

   the 
  greater 
  part 
  of 
  the 
  season. 
  

  

  The 
  Pest 
  Act. 
  — 
  The 
  results 
  of 
  the 
  Pest 
  Act 
  being 
  enforced 
  in 
  Coim- 
  

   batore 
  district 
  were 
  most 
  encouraging 
  in 
  spite 
  of 
  evasion 
  of 
  the 
  Act 
  

   in 
  some 
  cases, 
  and 
  ignorance, 
  apathy, 
  and 
  passive 
  resistance 
  on 
  the 
  

   part 
  of 
  some 
  of 
  the 
  subordinate 
  revenue 
  officials 
  and 
  village 
  officers. 
  

   It 
  remains 
  to 
  be 
  seen 
  whether 
  the 
  extension 
  of 
  the 
  area 
  under 
  the 
  Act 
  

   will 
  be 
  attended 
  by 
  equal 
  success. 
  

  

  The 
  control 
  of 
  the 
  pink 
  boll-worm 
  in 
  South 
  India 
  seems 
  to 
  lie 
  in 
  the 
  

   direction 
  of 
  strict 
  enforcement 
  of 
  the 
  Act, 
  in 
  the 
  encouragement 
  of 
  graz- 
  

   ing 
  off 
  bolls 
  by 
  sheep 
  and 
  goats 
  before 
  the 
  plants 
  are 
  pulled 
  up, 
  and 
  in 
  

   the 
  selection 
  of 
  an 
  early-maturing 
  strain 
  of 
  cotton. 
  This 
  applies 
  more 
  

   especially 
  to 
  Cambodia 
  cotton. 
  The 
  fact 
  that 
  the 
  pink 
  boll- 
  worm 
  shows 
  

   no 
  signs 
  of 
  producing 
  long-cycle 
  larvae 
  makes 
  control 
  by 
  the 
  above 
  means 
  

   more 
  easy 
  and 
  obviates 
  the 
  introduction 
  of 
  machines 
  or 
  other 
  apparatus 
  

   for 
  fumigating 
  or 
  otherwise 
  treating 
  the 
  seed 
  after 
  ginning. 
  

  

  Indeed, 
  it 
  is 
  very 
  doubtful 
  whether 
  it 
  would 
  ever 
  be 
  possible 
  to 
  

   enforce 
  treatment 
  of 
  seed 
  by 
  hot-air 
  machines 
  in 
  South 
  India, 
  and 
  it 
  

   would 
  be 
  useless 
  to 
  recommend 
  a 
  measure 
  which 
  could 
  not 
  be 
  made 
  obli- 
  

   gatory 
  for 
  ginning 
  factories. 
  

  

  Natural 
  Enemies. 
  — 
  The 
  larva 
  of 
  P. 
  gossypiella 
  is 
  parasitized 
  by 
  

   Microhracon 
  lefroyi 
  and 
  Ajjanteles 
  sp. 
  but 
  the 
  amount 
  of 
  check 
  

   exerted 
  by 
  them 
  is 
  not 
  great. 
  

  

  In 
  one 
  instance 
  the 
  nymph 
  of 
  what 
  appeared 
  to 
  be 
  a 
  Reduviid 
  bug 
  

   was 
  seen 
  sucking 
  eggs 
  laid 
  in 
  captivity 
  on 
  a 
  young 
  boll, 
  but 
  it 
  could 
  not 
  

   be 
  reared 
  to 
  maturity. 
  The 
  eggs, 
  needless 
  to 
  say, 
  failed 
  to 
  hatch. 
  This 
  

   was 
  the 
  only 
  occasion 
  that 
  the 
  eggs 
  were 
  found 
  to 
  be 
  so 
  attacked. 
  

  

  The 
  matter 
  comprising 
  this 
  paper 
  is 
  in 
  many 
  respects 
  very 
  incomplete 
  

   but 
  gives 
  an 
  idea 
  of 
  the 
  boll-worm 
  situation 
  in 
  Southern 
  Districts 
  of 
  

   South 
  India 
  at 
  the 
  present 
  time. 
  

  

  In 
  conclusion 
  I 
  wish 
  to 
  render 
  my 
  thanks 
  to 
  Mr. 
  H. 
  C. 
  Sampson.

  Director 
  of

  the

  help 
  rendered,
