  cuttings 
  for 
  propagation 
  purposes 
  have 
  to 
  be 
  taken 
  from 
  an 
  infested 
  

   vineyard, 
  the 
  precaution 
  of 
  thoroughly 
  fumigating 
  them 
  with 
  hydro- 
  

   cyanic 
  acid 
  gas 
  (1 
  oz. 
  to 
  150 
  cubic 
  ft.) 
  should 
  always 
  be 
  exercised. 
  

   This 
  gas 
  penetrates 
  crevices 
  slowly, 
  and 
  plants 
  exposed 
  to 
  it 
  should 
  

   not 
  be 
  tied 
  tightly 
  in 
  bundles. 
  It 
  is 
  illegal 
  to 
  send 
  vines 
  from 
  the 
  

   south-western 
  districts 
  of 
  the 
  Cape 
  to 
  other 
  parts 
  of 
  the 
  Union 
  unless 
  

   they 
  have 
  been 
  fumigated.

  Several 
  species 
  of 
  Limacodidae 
  feed 
  in 
  the 
  larval 
  stage 
  on 
  tea 
  and 
  

   at 
  times 
  do 
  a 
  considerable 
  amount 
  of 
  damage, 
  but 
  if 
  the 
  earhest 
  

   caterpillars 
  are 
  systematically 
  collected 
  and 
  destroyed, 
  much 
  labour 
  

   and 
  expense 
  will 
  be 
  avoided. 
  The 
  collectors 
  should 
  protect 
  their 
  

   hands 
  from 
  the 
  urticating 
  Hquid 
  secreted 
  by 
  these 
  larvae. 
  As 
  a 
  

   spray, 
  lead 
  arsenate 
  is 
  preferable 
  to 
  Paris 
  green, 
  which 
  is 
  liable 
  to 
  

   bum 
  the 
  foUage 
  ; 
  4 
  lb. 
  of 
  lead 
  arsenate 
  should 
  be 
  used 
  to 
  every 
  100 
  gals, 
  

   of 
  water. 
  In 
  order 
  to 
  avoid 
  the 
  danger 
  of 
  arsenical 
  poisoning, 
  

   pluckings 
  from 
  the 
  sprayed 
  area 
  should 
  be 
  rejected 
  until 
  the 
  new 
  

   growth, 
  which 
  was 
  in 
  bud 
  at 
  the 
  time 
  of 
  spraying, 
  has 
  developed. 
  

   Any 
  loss 
  would 
  be 
  amply 
  repaid 
  by 
  the 
  freedom 
  of 
  subsequent 
  crops 
  

   from 
  attack. 
  All 
  prunings 
  and 
  refuse 
  should 
  be 
  burned 
  and 
  the 
  

   pruned 
  and 
  surrounding 
  bushes 
  carefully 
  searched 
  for 
  cocoons 
  and 
  

   stray 
  larvae. 
  

  

  Natada 
  nararia, 
  the 
  fringed 
  nettle-grub, 
  is 
  probably 
  the 
  most 
  

   destructive 
  species 
  in 
  Ceylon. 
  The 
  larvae 
  are 
  attacked 
  by 
  an 
  Ichneu- 
  

   monid, 
  and 
  many 
  of 
  them 
  perish 
  from 
  what 
  is 
  perhaps 
  ?, 
  fungoid 
  

   disease. 
  The 
  pupal 
  stage 
  lasts 
  17 
  days. 
  The 
  blue-striped 
  nettle- 
  

   grub 
  (Parasa 
  lepida, 
  Cram.) 
  has 
  been 
  recorded 
  on 
  cacao, 
  coconut, 
  

   plantain, 
  cofiee, 
  castor, 
  mango, 
  asphal 
  {Nephelium

  and 
  

   country 
  abnond 
  (Terminalia 
  catappa), 
  as 
  well 
  as 
  on 
  tea, 
  and 
  the 
  pupal 
  

   stage 
  occupies 
  from 
  4 
  to 
  5 
  weeks. 
  Apanteles 
  sp. 
  have 
  been 
  reared 
  from 
  

   the 
  caterpillars 
  of 
  this 
  species 
  and 
  the 
  cocoons 
  of 
  these 
  parasites 
  are 
  

   often 
  destroyed 
  in 
  mistake 
  for 
  eggs 
  of 
  their 
  host.

  The 
  adult 
  moths 
  of 
  Enarmonia 
  batrachopa, 
  reared 
  from 
  acorns, 
  laid 
  

   their 
  eggs 
  very 
  readily 
  in 
  confinement 
  on 
  oranges. 
  The 
  fruit 
  was 
  

   attached 
  to 
  branches 
  with 
  leaves, 
  and 
  whilst 
  some 
  eggs 
  were 
  found 
  

   upon 
  the 
  foHage, 
  the 
  majority 
  were 
  scattered 
  promiscuously 
  upon 
  the 
  

   rind 
  of 
  the 
  fruit. 
  Upon 
  acorns, 
  the 
  eggs 
  are 
  laid 
  upon 
  the 
  smooth 
  

   shell, 
  and 
  none 
  were 
  found 
  upon 
  the 
  cup. 
  During 
  the 
  daytime 
  no 
  

   moths 
  were 
  found 
  on 
  the 
  wing 
  in 
  the 
  open, 
  and 
  those 
  in 
  the 
  breeding 
  

   cages 
  remained 
  quiet, 
  taking 
  such 
  shelter 
  as 
  the 
  cage 
  afforded. 
  In 
  

   confinement, 
  eggs 
  were 
  invariably 
  laid 
  after 
  nightfall, 
  and 
  there 
  is 
  no
