  Scalo." 
  This 
  insecticide 
  is 
  a 
  mixture 
  of 
  whale-oil 
  soap 
  

   and 
  kerosene, 
  the 
  formula 
  for 
  which 
  has 
  been 
  worked 
  out 
  by 
  Mr. 
  J. 
  C. 
  

   Moore, 
  Agricultural 
  Superintendent, 
  St. 
  Lucia. 
  The 
  stock 
  mixture 
  

   is 
  easily 
  diluted 
  in 
  water, 
  the 
  soap 
  holds 
  an 
  unusually 
  large 
  percentage 
  

   of 
  kerosene, 
  which 
  does 
  not 
  separate 
  out 
  even 
  when 
  kept 
  for 
  a 
  long 
  

   time. 
  To 
  control 
  the 
  bug, 
  spraying 
  would 
  have 
  to 
  be 
  done 
  at 
  a 
  time 
  

   when 
  the 
  eggs 
  were 
  hatching 
  or 
  had 
  just 
  hatched— 
  when 
  the 
  greatest 
  

   number 
  of 
  young 
  were 
  present. 
  Ground-nuts 
  are 
  also 
  attacked 
  by 
  

   several 
  other 
  bugs, 
  and 
  by 
  a 
  small 
  caterpillar 
  which 
  tunnels 
  into 
  the 
  

   tips 
  of 
  the 
  stems. 
  Mole 
  crickets 
  are 
  also 
  said 
  to 
  damage 
  them. 
  

  

  Cassava 
  pests. 
  The 
  cassava 
  at 
  the 
  Agricultural 
  School 
  was 
  attacked 
  

   by 
  a 
  species 
  of 
  Thrips 
  which 
  caused 
  a 
  considerable 
  deformation 
  of 
  the 
  

   leaves, 
  but 
  the 
  author 
  does 
  not 
  believe 
  that 
  it 
  causes 
  very 
  much 
  injury 
  

   to 
  the 
  crops. 
  

  

  Pigeon-pea 
  pests. 
  The 
  white 
  scale 
  {HemicJiionaspis 
  minor) 
  is 
  con- 
  

   trolled 
  to 
  a 
  large 
  extent 
  by 
  parasitic 
  insects 
  and 
  is 
  not 
  likely 
  to 
  cause 
  

   much 
  injury 
  to 
  pigeon-peas 
  when 
  these 
  occupy 
  the 
  land 
  as 
  a 
  12-15 
  

   months 
  crop, 
  but 
  if 
  allowed 
  to 
  remain 
  a 
  second 
  season 
  they 
  are 
  likely 
  to 
  

   become 
  seriously 
  infested, 
  even 
  to 
  the 
  point 
  of 
  infecting 
  adjoining 
  

   cotton 
  fields. 
  No 
  specific 
  directions 
  can 
  be 
  given 
  for 
  the 
  control 
  of 
  

   the 
  caterpillars 
  which 
  sometimes 
  eat 
  the 
  leaves, 
  or 
  of 
  -the 
  weevils 
  which 
  

   attack 
  the 
  pods 
  ; 
  but 
  it 
  is 
  hoped 
  planters 
  will 
  report 
  the 
  first 
  appear- 
  

   ance 
  of 
  any 
  of 
  these 
  pests 
  so 
  that 
  more 
  complete 
  knowledge 
  may 
  be 
  

   arrived 
  at. 
  

  

  Writing 
  after 
  the 
  date 
  of 
  the 
  above 
  report 
  the 
  author 
  mentions 
  that 
  

   the 
  cotton 
  worm 
  continued 
  to 
  spread 
  but 
  was 
  heavily 
  parasitised 
  by 
  

   two 
  Chalcid 
  flies, 
  Chalcis 
  ovata 
  and 
  Chalcis 
  sp., 
  and 
  quickly 
  disappeared. 
  

   This 
  outbreak 
  drew 
  attention 
  to 
  the 
  desirability 
  of 
  giving 
  still 
  further 
  

   encouragement 
  to 
  the 
  Jack 
  Spaniard. 
  A 
  trial 
  was 
  made 
  with 
  a 
  small 
  

   open 
  shed, 
  and 
  a 
  point 
  clearly 
  brought 
  out 
  was 
  that 
  effective 
  shelter 
  

   from 
  wind 
  and 
  rain 
  is 
  necessary 
  and 
  that 
  the 
  roofs 
  of 
  the 
  sheds 
  should 
  

   be 
  raised 
  to 
  a 
  height 
  of 
  not 
  less 
  than 
  7 
  feet 
  so 
  as 
  to 
  allow 
  the 
  nests 
  to 
  

   hang 
  well 
  above 
  the 
  heads 
  of 
  labourers 
  who 
  may 
  take 
  temporary 
  

   shelter 
  in 
  showery 
  weather 
  under 
  the 
  sheds. 
  " 
  Scalo 
  " 
  has 
  been 
  found 
  

   very 
  effective, 
  and 
  if 
  used 
  at 
  the 
  rate 
  of 
  1 
  lb. 
  to 
  a 
  gallon 
  of 
  water 
  was 
  

   found 
  not 
  to 
  damage 
  any 
  but 
  the 
  very 
  tender 
  plants. 
  

  

  A 
  " 
  Stoppeur 
  " 
  air-compressing 
  pump 
  and 
  four 
  compressed 
  air 
  

   knapsack 
  sprayers 
  proved 
  very 
  effective. 
  Specimens 
  of 
  the 
  " 
  Furet 
  " 
  

   duster 
  were 
  also 
  obtained. 
  This 
  is 
  quite 
  the 
  best 
  type 
  of 
  apphance 
  so 
  

   far 
  used 
  for 
  applying 
  insecticides 
  in 
  powder 
  form. 
  It 
  is 
  worked 
  by 
  one 
  

   hand 
  alone, 
  and 
  by 
  a 
  simple 
  contrivance 
  it 
  can 
  be 
  regulated 
  to 
  eject 
  a 
  

   fine, 
  medium, 
  or 
  heavy 
  dust.

  The 
  heavy 
  rain 
  in 
  October 
  promoted 
  the 
  cotton 
  crop, 
  but 
  insect 
  pests 
  

   also 
  multiplied, 
  and 
  a 
  severe 
  attack 
  of 
  cotton 
  worms 
  {Alabama 
  

   argillacea) 
  resulted 
  in 
  many 
  districts. 
  To 
  allow 
  peasant 
  growers 
  to 
  

   deal 
  with 
  this 
  pest, 
  considerable 
  quantities 
  of 
  Paris 
  green 
  were 
  given 
  

   away. 
  With 
  Sea 
  Island 
  cotton, 
  success 
  has 
  followed 
  selection 
  work 
  

   with 
  Cameron 
  106, 
  a 
  strain 
  numbered 
  12*5 
  being 
  remarkable 
  in 
  that 
  it 
  is 
  

   a 
  late 
  bearer, 
  remarkably 
  vigorous, 
  and 
  decidedly 
  resistant 
  to 
  leaf- 
  

   blister 
  mite.
