﻿PROCEEDINGS 
  OF 
  THE 
  FOURTH 
  ENTOMOLOGICAL 
  MEETING 
  163 
  

  

  The 
  second 
  part 
  of 
  the 
  work 
  has 
  already 
  been 
  done 
  satisfactorily 
  

   and 
  as 
  regards 
  the 
  first 
  a 
  few 
  more 
  months 
  worlc 
  is 
  necesfary 
  to 
  come 
  

   to 
  a 
  definite 
  conclusion 
  and 
  if 
  as 
  satisfactory 
  and 
  definite 
  a 
  result 
  is 
  

   obtained 
  in 
  this 
  case 
  as 
  in 
  the 
  first, 
  it 
  is 
  hoped 
  that 
  it 
  will 
  be 
  possible 
  

   to 
  control 
  a 
  very 
  serious 
  pest 
  of 
  the 
  Province 
  by 
  a 
  much 
  cheaper 
  and 
  

   more 
  effective 
  method 
  than 
  has 
  hitherto 
  been 
  employed. 
  

  

  At 
  Pus3 
  we 
  have 
  been 
  able 
  to 
  carry 
  Agrotis 
  ypsilon 
  on 
  through 
  the 
  Mr. 
  Fletcher, 
  

   hot 
  weather 
  into 
  August. 
  

  

  I 
  could 
  not 
  carry 
  it 
  through 
  the 
  summer. 
  I 
  tried 
  all 
  favourable 
  Mr. 
  H. 
  L. 
  Dutt. 
  

   conditions. 
  It 
  is 
  drier 
  South 
  of 
  the 
  Ganges 
  than 
  North 
  of 
  it. 
  Our 
  

   humidity 
  goes 
  down 
  to 
  10-12 
  per 
  cent. 
  Pusa, 
  I 
  understand, 
  does 
  not 
  

   go 
  below 
  25 
  per 
  cent. 
  

  

  We 
  tried 
  experiments 
  on 
  prolonging 
  the 
  development 
  of 
  resting 
  Mr. 
  Beeson. 
  

   lon^icorn 
  larvae 
  by 
  desiccation 
  and 
  found 
  that 
  though 
  we 
  could 
  delay 
  

   it 
  for 
  a 
  few 
  weeks, 
  further 
  delay 
  resulted 
  in 
  death 
  and 
  we 
  could 
  never 
  

   postpone 
  it 
  until 
  next 
  year. 
  Desiccation 
  went 
  on 
  for 
  several 
  months 
  

   during 
  the 
  resting 
  period 
  of 
  the 
  larvae, 
  which 
  lost 
  up 
  to 
  75 
  per 
  cent, 
  of 
  

   water 
  before 
  they 
  died. 
  

  

  Where 
  did 
  you 
  get 
  the 
  Shillong 
  larvaj 
  of 
  Agrofiff 
  ypsilon 
  ? 
  Mr. 
  Fletcher. 
  

  

  From 
  potato 
  on 
  the 
  farm 
  at 
  Upper 
  Shillong. 
  Mr. 
  Gupta. 
  

  

  I 
  have 
  never 
  seen 
  Agrotis 
  ypsilon 
  in 
  Shillong. 
  Were 
  there 
  any 
  Mr. 
  Fletcher, 
  

   parasites 
  on 
  the 
  specimens 
  from 
  Shillong 
  ? 
  

  

  These 
  specimens 
  were 
  reared 
  in 
  the 
  Insectary 
  and 
  the 
  adults 
  proved 
  Mr. 
  H. 
  L. 
  Dutt. 
  

   to 
  be 
  ^. 
  ypsilon. 
  There 
  were 
  no 
  parasites 
  on 
  the 
  Shillong 
  larvse. 
  

  

  In 
  the 
  Plains 
  of 
  Assam 
  we 
  get 
  the 
  caterpillars 
  of 
  A. 
  ypsilon 
  very 
  Mr. 
  Gupta, 
  

   commonly 
  and 
  also 
  the 
  parasites. 
  

  

  There 
  are 
  two 
  Braconid 
  parasites 
  in 
  Bihar. 
  Which 
  one 
  do 
  you 
  get 
  Mr. 
  H. 
  L. 
  Dutt. 
  

   in 
  Assam 
  ? 
  

  

  The 
  one 
  with 
  the 
  white 
  cocoon. 
  Mr. 
  Gupta. 
  

  

  The 
  one 
  with 
  the 
  brown 
  cocoon 
  is 
  more 
  common 
  in 
  Bihar. 
  Mr. 
  H. 
  L. 
  Dutt.
