   The 
  leaf-blister 
  mite 
  of 
  cotton 
  (Eriopkyes 
  gossypii) 
  has 
  spread 
  over 
  

   all 
  the 
  cotton-gro^Ning 
  areas 
  and 
  has 
  become 
  a 
  very 
  serious 
  pest. 
  The 
  

   removal 
  by 
  law 
  of 
  all 
  old 
  cotton 
  before 
  the 
  season

  replanting 
  offers, 
  

   under 
  Barbados 
  conditions, 
  a 
  fair 
  chance 
  of 
  getting 
  rid 
  of 
  it 
  entirely.

  type 
  growing 
  among

  Sea

  show 
  no 
  signs 
  of 
  the 
  presence

  the

  Thrips 
  (Euthrips 
  

   sp.), 
  flea-beetle 
  {Chaetocnema 
  anmzona) 
  and 
  a 
  red 
  spider 
  (Tetranychus 
  

   telarius) 
  are 
  pests 
  of 
  sweet 
  potatoes, 
  and 
  are 
  generally 
  most 
  troublesome 
  

   in 
  dry 
  weather. 
  Shps 
  for

  be 
  fumigated 
  in 
  a 
  tight 
  

   wooden 
  box 
  by 
  means 
  of 
  carbon

  at 
  the 
  rate 
  of 
  1 
  dram 
  to 
  

   each

  The 
  cassava 
  hawk-moth, 
  (Erinnyis 
  

   (Dilophonota) 
  ello) 
  severely 
  attacked 
  cassava 
  fields, 
  the 
  plants 
  being 
  

   completely 
  defohated 
  over 
  about 
  12 
  acres. 
  Four 
  broods 
  of 
  caterpillars 
  

   were 
  observed, 
  occurring 
  at 
  intervals 
  of 
  30 
  days, 
  and 
  it 
  was 
  estimated 
  

   that 
  there 
  were 
  8 
  broods 
  in 
  the 
  season. 
  Spraying 
  with 
  arsenate 
  of 
  

   lead 
  and 
  dusting

  are 
  effective. 
  The 
  spray 
  contained 
  

   4 
  lb. 
  of 
  arsenate 
  and 
  50 
  pints 
  of 
  molasses 
  to 
  every 
  50 
  gals, 
  of 
  water, 
  

   the 
  molasses 
  being 
  added 
  to 
  overcome 
  the 
  water-repelhng 
  property 
  of 
  

   the 
  cassava 
  leaves. 
  Paris 
  green 
  was 
  used 
  at 
  the 
  rate 
  of 
  1 
  lb. 
  to 
  6 
  lb. 
  

   of 
  Hme. 
  The 
  larvae 
  and 
  pupae 
  are 
  eaten 
  by 
  the 
  Barbados 
  blackbirds 
  

   {Quiscalus 
  fartirostris), 
  the 
  larvae 
  by 
  wasps 
  (PoUstes 
  spp.) 
  and 
  the 
  

   moths 
  by 
  the 
  rain 
  bird 
  (Tyr 
  annus 
  rostratus). 
  No 
  Tachinid 
  flies 
  or 
  

   other 
  parasites 
  were 
  observed. 
  The 
  larva 
  of 
  the 
  whitewood 
  moth 
  

   [Duomitus 
  punctifer) 
  were 
  found 
  tunnelhng 
  in 
  whitewood 
  (Tecoyna 
  

   leucoxylon), 
  sour 
  sop 
  [Anona 
  muricata), 
  Barbados 
  cherry 
  (Malphigia 
  

   glabra), 
  the 
  woody 
  stems 
  of 
  Ipomoea 
  vines 
  and 
  in 
  ornamental 
  crotons 
  

   (Codiaeum 
  spp.). 
  The 
  Coccidae 
  recorded 
  during 
  1912-13 
  include 
  : 
  — 
  

   Aspidiotus 
  (Chrysomphalus) 
  howreyi, 
  CklL, 
  on 
  agaves, 
  and 
  Pseudaonidia 
  

   fesserata, 
  De 
  Charm., 
  on 
  Cassia 
  fistula. 
  Another 
  scale, 
  closely 
  

   resembhng 
  the 
  last-named 
  and 
  probably 
  a 
  new 
  variety, 
  was 
  found 
  

   on 
  grape 
  vine 
  and 
  Vitis 
  sicyoides. 
  It 
  is 
  capable 
  of 
  doing 
  much 
  damage, 
  

   occurring 
  under 
  the 
  bark 
  and 
  causing 
  great 
  numbers 
  of 
  small 
  swelhngs. 
  

   Chionaspis 
  unilateralis, 
  Newst., 
  on 
  a 
  palm 
  {Thrinax), 
  is 
  a 
  new 
  species. 
  

   Coccus 
  (Lecanium) 
  hesperidum, 
  L., 
  has 
  been 
  identified 
  as 
  occurring 
  

   on 
  Pluchea 
  odorata 
  and 
  on 
  seedhngs 
  of 
  Sterculia 
  fulgens. 
  This 
  is 
  of 
  

   interest, 
  since 
  the 
  original 
  records 
  of 
  C. 
  hesperidum, 
  as 
  being 
  abundant 
  

   and 
  injurious 
  in 
  Barbados 
  and 
  other 
  of 
  the 
  Lesser 
  Antilles 
  probably 
  

   referred 
  to 
  Coccus 
  viridis, 
  while 
  C. 
  hesperidum 
  was 
  and 
  is 
  a 
  rare 
  insect. 
  

   An 
  experimental 
  plot 
  of 
  papaw 
  was 
  severely 
  attacked 
  by 
  leaf-hoppers 
  

   ( 
  Jassidae), 
  apparently 
  the 
  same 
  species 
  which 
  occurs 
  on 
  cotton 
  without 
  

   causing 
  injury. 
  Resin 
  compound 
  checked 
  the 
  attack, 
  but 
  reinfestation 
  

   soon 
  took 
  place.

  list 
  of 
  borer 
  pests 
  of

  : 
  — 
  

   Batocera 
  albofasciata, 
  de

  and 
  B. 
  gigas, 
  Drap., 
  are 
  found 
  

   throughout 
  Java,

  although 
  the 
  damage 
  they 
  do 
  is 
  very 
  serious, 
  

   they 
  are 
  rarely 
  seen, 
  being 
  nocturnal 
  and 
  hiding 
  themselves 
  in 
  comers
