   Contarinia 
  androfoginis, 
  parasitized 
  by 
  Tetrastichus 
  coimhatorensis, 
  

   Roliwer, 
  has 
  not 
  been 
  noticed 
  since 
  my 
  return, 
  nor 
  have 
  I 
  seen 
  Itonida 
  

   seminis 
  on 
  cumhu. 
  I 
  have 
  a 
  note 
  on 
  the 
  habits 
  of 
  C. 
  andropoginis

  Heliothis 
  ohsoleta 
  was 
  quite 
  a 
  bad 
  pest 
  of 
  cotton 
  last 
  year 
  

   (1920) 
  on 
  the 
  Central 
  Farm. 
  I 
  have 
  a 
  note 
  on 
  the 
  fact 
  in 
  the 
  Agricul- 
  

   tural 
  Journal. 
  It 
  is 
  not 
  so 
  far 
  in 
  pest 
  conditions 
  this 
  year 
  but 
  I 
  have 
  

   seen 
  one 
  or 
  two 
  larvae 
  eating 
  cotton 
  bolls 
  and 
  there 
  was 
  a 
  brood 
  early 
  

   in 
  December 
  on 
  Corchorus 
  oUtonus, 
  L. 
  It 
  is 
  late 
  in 
  attacking 
  the 
  second 
  

   xrop 
  of 
  Bengal 
  gram 
  this 
  year 
  ; 
  usually 
  it 
  is 
  a 
  very 
  serious 
  pest 
  of 
  this 
  

  

  crop.

  Cir'phis 
  albistigma 
  ; 
  not 
  reported 
  in 
  1920.

  Lafliijgma 
  exigua 
  entirely 
  destroyed 
  a 
  field 
  of 
  Linseed 
  on 
  

   the 
  Central 
  Farm 
  in 
  1919. 
  The 
  swarm 
  swept 
  through 
  the 
  field 
  with 
  

   astonishing 
  rapidity. 
  I 
  noticed 
  many 
  being 
  killed 
  by 
  large 
  black 
  ants 
  

   (Camponotus). 
  

  

  P. 
  79. 
  Earias 
  jabia 
  and 
  insulana 
  are 
  much 
  less 
  serious 
  this 
  year 
  

   than 
  last. 
  It 
  makes 
  its 
  appearance 
  with 
  great 
  regularity 
  about 
  15th 
  

   October, 
  As 
  far 
  as 
  my 
  experience 
  goes 
  it 
  does 
  not 
  attack 
  shoots 
  when 
  

   bolls 
  are 
  to 
  be 
  had. 
  It 
  is 
  especially 
  fond 
  of 
  Alutilon 
  graveolens. 
  

  

  P. 
  81. 
  Achcea 
  Janata 
  is 
  chiefly 
  a 
  pest 
  in 
  November 
  and 
  December. 
  

   There 
  were 
  two 
  broods 
  of 
  this 
  insect 
  at 
  Coimbatore 
  at 
  this 
  time 
  in 
  1919. 
  

   I 
  am 
  doubtful 
  of 
  the 
  efficacy 
  of 
  hand-picking 
  which 
  was 
  resorted 
  to 
  

   on 
  the 
  farm 
  and 
  found 
  to 
  be 
  both 
  slow 
  and 
  expensive. 
  I 
  think 
  dusting 
  

   has 
  possibilities 
  but 
  it 
  is 
  doubtful 
  how 
  far 
  the 
  raiyat 
  is 
  to 
  be 
  trusted 
  

   with 
  stomach-poisons, 
  

  

  Chilo 
  simplex. 
  The 
  eggs 
  are 
  parasitized 
  by 
  Tetrastichus 
  ayyari, 
  

   Rohwer.

  ScJicenohius

  T. 
  V. 
  Eamakrishna 
  Ayyar 
  noted 
  

   it 
  in 
  large 
  numbers 
  all 
  over 
  the 
  foot 
  bridge 
  of 
  Shoranur 
  station 
  in 
  Mala- 
  

   bar, 
  attracted 
  to 
  the 
  light 
  and 
  laying 
  eggs 
  on 
  the 
  bridge. 
  The 
  night 
  

   was 
  wet. 
  

  

  I 
  have 
  an 
  experimental 
  area 
  of 
  about 
  120 
  acres 
  at 
  Podalada 
  in 
  

   Kistna 
  district 
  in 
  the 
  Godavari 
  delta. 
  We 
  have 
  been 
  working 
  there 
  

   since 
  January 
  1920, 
  The 
  scheme 
  followed 
  is 
  to 
  select 
  all 
  seedlings 
  

   showing 
  dead-hearts 
  at 
  the 
  time 
  of 
  transplantation. 
  These 
  seedhngs 
  

   are 
  rejected 
  and 
  destroyed. 
  The 
  general 
  attack 
  of 
  Schwnobius 
  in 
  the 
  

   delta 
  has 
  been 
  very 
  low. 
  This 
  year 
  about 
  4 
  per 
  cent, 
  of 
  dead-hearts
