  coeruleipennis, 
  Blanch., 
  it 
  has 
  been 
  found 
  a 
  good 
  plan 
  to 
  cut 
  off 
  

   the 
  tips 
  of 
  infested 
  fronds. 
  The 
  cosmopolitan 
  Necrobia 
  rufipes, 
  

   De 
  Geer, 
  is 
  very 
  abundant 
  in 
  copra 
  in 
  the 
  Philippine 
  Islands 
  ; 
  it 
  is 
  best 
  

   controlled 
  by 
  fumigation 
  with 
  carbon 
  bisulphide 
  under 
  a 
  tarpaulin. 
  

  

  The 
  Longicorns, 
  Xixuthrus 
  costatus, 
  Mont., 
  from 
  Russell 
  Island 
  

   Group 
  and 
  Java, 
  and 
  Olethrius 
  tyrannus, 
  Thorns., 
  in 
  the 
  Solomon 
  

   Islands 
  and 
  the 
  New 
  Hebrides, 
  also 
  damage 
  coconuts. 
  

  

  The 
  Phasmids, 
  Graeffea 
  {Lopaphus) 
  cocophaga, 
  Newp., 
  which 
  has 
  a 
  

   wide 
  range 
  in 
  New 
  South 
  Wales, 
  New 
  Caledonia, 
  Caroline 
  Islands, 
  ly 
  

   Cook 
  Islands, 
  Tonga, 
  Samoa, 
  Solomon 
  and 
  Marquise 
  Islands, 
  and 
  

   Hemarchus 
  (Phihalosoma) 
  pythonius, 
  Westw., 
  greatly 
  damage 
  the 
  

   coconut 
  foliage. 
  Where 
  they 
  attack 
  trees 
  of 
  moderate 
  height, 
  the 
  

   foliage 
  can 
  be 
  sprayed 
  with 
  lead 
  arsenate. 
  

  

  Several 
  species 
  of 
  locusts 
  and 
  grasshoppers 
  occur 
  in 
  the 
  Solomon 
  

   Islands, 
  where 
  they 
  attack 
  the 
  palms. 
  They 
  should 
  be 
  poisoned 
  

   before 
  they 
  reach 
  the 
  flying 
  stage 
  by 
  spreading 
  poisoned 
  food 
  under- 
  

   neath 
  the 
  trees. 
  The 
  simplest 
  arsenical 
  spray 
  is 
  : 
  white 
  arsenic 
  

   (arsenious 
  oxide) 
  1 
  lb. 
  ; 
  washing 
  soda, 
  1 
  lb. 
  ; 
  sugar 
  or 
  treacle, 
  

   2 
  to 
  4 
  lb. 
  ; 
  water, 
  17 
  gallons. 
  Boil 
  the 
  arsenic 
  and 
  soda 
  together 
  in 
  a 
  

   kerosene 
  tin 
  with 
  2 
  gallons 
  water, 
  and 
  when 
  dissolved, 
  add 
  the 
  sugar 
  

   already 
  in 
  solution 
  in 
  the 
  rest 
  of 
  the 
  water, 
  making 
  the 
  whole 
  up 
  to 
  

   17 
  gallons. 
  

  

  Aleurodicus 
  cocois, 
  Curtis, 
  formerly 
  infested 
  coconut 
  palms 
  in 
  

   Barbados 
  and 
  the 
  guava 
  in 
  Trinidad, 
  but 
  has 
  not 
  been 
  recorded 
  on 
  

   the 
  coconut 
  since 
  1831. 
  

  

  The 
  numerous 
  Coccids 
  include 
  Aspidiotus 
  destructor, 
  Sign., 
  which 
  is 
  

   the 
  worst 
  scale-insect 
  attacking 
  the 
  coconut, 
  and 
  is 
  very 
  widely 
  distri- 
  

   buted. 
  Kerosene 
  emulsion 
  or 
  resin- 
  wash 
  is 
  an 
  effective 
  spray 
  against 
  

   it, 
  while 
  fumigation 
  might 
  be 
  employed 
  where 
  a 
  large 
  number 
  of 
  small 
  

   trees 
  are 
  infested. 
  A. 
  oceanica, 
  Lind., 
  occurs 
  on 
  the 
  coconut 
  

   fronds 
  in 
  the 
  South 
  Sea 
  Islands. 
  If 
  the 
  palms 
  are 
  sufiiciently 
  small, 
  

   spray 
  with 
  kerosene 
  emulsion, 
  red 
  oil 
  or 
  resin-wash 
  ; 
  where 
  the 
  ground 
  

   is 
  clear 
  it 
  would 
  be 
  as 
  cheap 
  to 
  tent 
  and 
  fumigate 
  the 
  palms. 
  

  

  Hemichionaspis 
  (Chionaspis) 
  aspidistras, 
  Sign., 
  is 
  doing 
  great 
  damage 
  

   to 
  the 
  coconut 
  palms 
  in 
  the 
  New 
  Hebrides, 
  where 
  it 
  often 
  covers 
  the 
  

   trunks 
  as 
  well. 
  Spraying 
  with 
  red 
  oil 
  or 
  kerosene 
  emulsion 
  is 
  advised, 
  

   a 
  steam 
  sprayer 
  being 
  required 
  for 
  the 
  larger 
  trees. 
  Dactylopius 
  sp., 
  

   was 
  found 
  clustering 
  round 
  the 
  foot-stalks 
  and 
  fingers 
  of 
  the 
  bunches 
  of 
  

   young 
  coconuts. 
  It 
  would 
  be 
  advisable, 
  where 
  these 
  are 
  found, 
  to 
  

   open 
  out 
  the 
  base 
  of 
  the 
  sheath 
  and 
  brush 
  out 
  all 
  the 
  pests 
  with 
  a 
  paint- 
  

   brush 
  dipped 
  in 
  tobacco 
  and 
  soap 
  emulsion 
  or 
  weak 
  kerosene 
  emulsion. 
  

  

  The 
  flower 
  and 
  fruit 
  of 
  the 
  coconut 
  are 
  attacked 
  by 
  the 
  Pentatomid 
  

   bug, 
  Axiagastus 
  cambelli, 
  Dist., 
  which 
  is 
  well 
  known 
  on 
  the 
  Solomon 
  

   Island 
  plantations. 
  The 
  caterpillars 
  of 
  the 
  Zygaenid, 
  Leonana 
  iridescens, 
  

   B. 
  B., 
  occur 
  in 
  great 
  numbers 
  on 
  the 
  undersides 
  of 
  the 
  fronds, 
  on 
  which 
  

   they 
  feed. 
  At 
  present 
  they 
  are 
  confined 
  to 
  Fiji. 
  Small 
  palms 
  may 
  

   be 
  sprayed 
  with 
  kerosene 
  emulsion 
  or 
  resin-wash. 
  The 
  larva 
  of 
  the 
  

   Pyralid, 
  Harpagoneura 
  complena, 
  Feld., 
  causes 
  slight 
  damage 
  by 
  eating 
  

   away 
  the 
  young 
  nut 
  and 
  causing 
  it 
  to 
  fall 
  before 
  it 
  is 
  ripe. 
  In 
  the 
  

   New 
  Hebrides 
  they 
  were 
  observed 
  inside 
  the 
  flower 
  spathes, 
  where 
  

   they 
  did 
  considerable 
  damage.
