  FOURTH

  MEETING

  P. 
  212. 
  Batocera 
  ruhus. 
  This 
  was 
  sent 
  to 
  me 
  and 
  reported 
  to 
  be 
  

   attacking 
  rubber 
  in 
  the 
  Mooply 
  valley 
  in 
  1920. 
  Only 
  one 
  or 
  two 
  trees 
  

   were 
  attacked. 
  

  

  P. 
  235. 
  Leptispa 
  pygmcea. 
  Not 
  much 
  is 
  known 
  about 
  it. 
  As 
  far 
  

   as 
  I 
  know 
  at 
  present 
  it 
  is 
  more 
  localised 
  than 
  Hispa. 
  

  

  P. 
  237. 
  Hispa 
  armigera. 
  This 
  is 
  a 
  serious 
  pest 
  of 
  all 
  three 
  crops 
  

   of 
  paddy 
  in 
  South 
  Kanara. 
  In 
  response 
  to 
  appeals 
  from 
  the 
  Acting 
  

   Collector, 
  I 
  arranged 
  for 
  a 
  demonstration 
  in 
  spraying 
  as 
  a 
  control 
  for 
  

   this 
  pest. 
  Crude 
  oil 
  emulsion 
  was 
  used 
  and 
  certainly 
  acted 
  as 
  a 
  deter- 
  

   rent 
  and 
  where 
  seed 
  beds 
  were 
  taken 
  in 
  time 
  was 
  successful. 
  However 
  I 
  

   do 
  not 
  think 
  it 
  is 
  a 
  very 
  practicable 
  proposition 
  even 
  if 
  worked 
  through 
  

   co-operative 
  societies. 
  Bagging 
  and 
  clipping 
  are 
  equally 
  efficacious. 
  

   Great 
  success 
  was 
  obtained 
  in 
  one 
  field 
  which 
  it 
  was 
  possible 
  to 
  flood 
  

   by 
  running 
  in 
  water 
  with 
  crude 
  oil 
  emulsion 
  floating 
  on 
  it. 
  This 
  might 
  

   be 
  a 
  useful 
  control 
  for 
  the 
  first 
  crop. 
  But 
  a 
  great 
  deal 
  of 
  study 
  is 
  needed 
  

   of 
  this 
  insect 
  and 
  our 
  control 
  methods 
  are 
  merely 
  stop-gaps, 
  like 
  the 
  

   majority 
  of 
  the 
  so-called 
  remedies 
  for 
  crop 
  p^ests. 
  

  

  To 
  my 
  mind 
  Hispa 
  is' 
  famous 
  for 
  the 
  fact 
  that, 
  as 
  far 
  as 
  I 
  am 
  aware, 
  

   it 
  is 
  the 
  only 
  insect 
  which 
  has 
  been 
  mentioned 
  by 
  name 
  in 
  the 
  weekly 
  

   reports 
  of 
  the 
  Collector 
  of 
  a 
  District 
  to 
  Government. 
  I 
  am 
  not 
  sure 
  

   that 
  it 
  was 
  not 
  mentioned 
  in 
  the 
  Government 
  of 
  India's 
  report 
  to 
  the 
  

   Secretary 
  of 
  State. 
  

  

  Hispa 
  armigera 
  does 
  not 
  seem 
  to 
  be 
  a 
  serious 
  pest 
  in 
  Malabar. 
  Fur- 
  

   ther 
  experience 
  may 
  show 
  otherwise. 
  

  

  P. 
  242. 
  Gnathospastoides 
  rouxi, 
  Cast. 
  An 
  interesting 
  method 
  of 
  

   control 
  is 
  used 
  in 
  Bellary. 
  Assafoetida 
  is 
  mixed 
  with 
  cow-dung. 
  In 
  

   this 
  beetles 
  which 
  have 
  been 
  caught 
  are 
  rolled 
  and 
  then 
  liberated. 
  Rai- 
  

   yats 
  claim 
  that 
  they 
  drive 
  other 
  beetles 
  out 
  of 
  the 
  fields 
  !! 
  

  

  P. 
  244. 
  Elateridce. 
  Elaterid 
  grubs 
  were 
  found 
  eating 
  paddy 
  seed- 
  

   ling 
  roots 
  in 
  Kistna 
  district. 
  The 
  adults 
  were 
  not 
  reared. 
  

  

  P. 
  244. 
  SpJienoptera 
  gossypii. 
  The 
  Deputy 
  Director 
  of 
  Agricul- 
  

   ture, 
  III 
  Circle, 
  tells 
  me 
  that 
  in 
  the 
  Ceded 
  Districts 
  S. 
  gossypii 
  is 
  a 
  

   serious 
  pest 
  of 
  cotton. 
  

  

  Rhynchota. 
  

  

  P. 
  257. 
  Leptocorisa 
  varicornis. 
  Eotting 
  flesh 
  was 
  tried 
  without 
  

   success 
  at 
  Coimbatore 
  as 
  a 
  bait. 
  Bagging 
  is 
  quite 
  successful 
  and 
  kept 
  

   them 
  under 
  control 
  on 
  the 
  Central 
  Farm 
  this 
  year. 
  This 
  might 
  be 
  

   due 
  to 
  early 
  ripening 
  of 
  some 
  varieties 
  of 
  paddy 
  in 
  which 
  the 
  bugs 
  con- 
  

   gregated 
  and 
  on 
  which 
  they 
  were 
  caught.
