   rhinoceros

  Strategus

  A 
  pest

  The 
  occurrence 
  of 
  a 
  pest 
  causing 
  injury 
  to 
  oranges 
  in 
  Dominica, 
  has 
  

   recently 
  been 
  reported. 
  It 
  is 
  a 
  small 
  moth 
  related 
  to 
  the 
  codling 
  

   moth 
  (Cydia 
  pomonella). 
  The 
  larva 
  injures 
  the 
  fruit 
  by 
  penetrating 
  

   the 
  sldn 
  and 
  feeding 
  in 
  the 
  pulp 
  of 
  the 
  orange, 
  which 
  becomes 
  dis- 
  

   coloured 
  and 
  rotten 
  in 
  the 
  vicinity. 
  Even 
  when 
  no 
  further 
  injury 
  

   is 
  done 
  than 
  the 
  puncture 
  of 
  the 
  skin, 
  the 
  fruit 
  is 
  rendered 
  unsaleable 
  

   on 
  account 
  of 
  the 
  discoloration 
  at 
  the 
  point 
  of 
  attack 
  and 
  the 
  mal- 
  

   formation 
  which 
  often 
  results. 
  This 
  pest 
  was 
  first 
  noticed 
  in 
  1907, 
  

   and 
  again 
  in 
  1908. 
  Remedial 
  measures, 
  and 
  especially 
  spraying 
  

   with 
  lead 
  arsenate, 
  led 
  to 
  complete 
  control 
  in 
  1909 
  and 
  1910. 
  Since 
  

   then 
  no 
  records 
  of 
  its 
  occurrence 
  have 
  been 
  received 
  until 
  1913. 
  The 
  

   agricultural 
  officers 
  in 
  Dominica 
  state 
  that 
  the 
  attack 
  begins 
  in 
  May 
  

   or 
  June, 
  the 
  egg 
  being 
  laid 
  on 
  the 
  surface 
  of 
  the 
  fruit. 
  During 
  August, 
  

   the 
  larval 
  stage 
  is 
  completed 
  and 
  the 
  full-grown 
  caterpillar 
  leaves 
  the 
  

   fruit 
  (which 
  by 
  this 
  time 
  has 
  fallen 
  to 
  the 
  ground) 
  and 
  enters 
  the 
  pupal 
  

   stage 
  amongst 
  the 
  leaves 
  on 
  the 
  ground. 
  About 
  two 
  weeks 
  later 
  the 
  

   moths 
  emerge. 
  What 
  becomes 
  of 
  the 
  insect 
  in 
  the 
  other 
  months 
  is 
  

   not 
  known. 
  The 
  most 
  successful 
  control 
  resulted 
  from 
  spraying 
  with 
  

   lead 
  arsenate, 
  applied 
  early 
  in 
  the 
  season, 
  in 
  order 
  that 
  the 
  newly 
  

   hatched 
  caterpillars 
  may 
  be 
  poisoned 
  as 
  they 
  attempt 
  to 
  eat 
  their 
  way 
  

   through 
  the 
  orange 
  skin.

  Froghoppers. 
  During 
  the 
  years 
  1912 
  and 
  1913, 
  51 
  fields 
  out 
  of 
  110 
  

   on 
  an 
  estate 
  in 
  the 
  Couva 
  district 
  of 
  which 
  a 
  record 
  was 
  kept 
  were 
  

   affected. 
  In 
  1912, 
  25 
  fields 
  were 
  badly 
  affected, 
  19 
  slightly, 
  and 
  7 
  had 
  

   no 
  blight. 
  In 
  1913, 
  8 
  fields 
  were 
  badly 
  affected, 
  24 
  slightly 
  and 
  19 
  

   had 
  no 
  blight 
  ; 
  6 
  fields 
  were 
  badly 
  blighted 
  in 
  1912 
  and 
  1913 
  : 
  5 
  

   fields 
  were 
  slightly 
  blighted 
  in 
  1913 
  which 
  were 
  not 
  so 
  affected 
  in 
  

   1912. 
  Ratoon 
  canes 
  were 
  mostly 
  affected. 
  Egg-parasites 
  : 
  — 
  The 
  

   survey 
  for 
  the 
  occurrence 
  of 
  egg-parasites 
  is 
  not 
  completed 
  yet, 
  but 
  

   to 
  the 
  end 
  of 
  September 
  1913 
  they 
  occurred 
  in 
  12 
  fields 
  and 
  with 
  the 
  

   exception 
  of 
  one, 
  none 
  of 
  the 
  fields 
  had 
  blight 
  at 
  any 
  time 
  during 
  1912 
  

   and 
  1913. 
  The 
  single 
  field 
  referred 
  to 
  was 
  only 
  slightly 
  blighted 
  in 
  

   both 
  years. 
  Green 
  Muscardine 
  Fungus 
  : 
  — 
  In 
  1912, 
  of 
  the 
  51 
  fields 
  

   19 
  were 
  sprayed 
  with 
  fungus 
  spores, 
  and 
  in 
  1 
  913, 
  16 
  fields 
  were 
  similarly 
  

   treated 
  ; 
  12 
  fields 
  with 
  bhght 
  sprayed 
  with 
  spores 
  in 
  1912 
  showed 
  

   no 
  blight 
  in 
  1913 
  ; 
  7 
  blighted 
  fields, 
  although 
  sprayed 
  with 
  spores 
  

   in 
  1912, 
  showed 
  blight 
  again 
  in 
  1913, 
  but 
  as 
  a 
  rule 
  the 
  blight 
  was 
  

   shght, 
  showing 
  that 
  some 
  good 
  was 
  done. 
  Sp'ead 
  of 
  Froghoppers 
  : 
  — 
  

   In 
  1913, 
  five 
  new 
  fields 
  were 
  attacked 
  and 
  all 
  were 
  near 
  fields 
  affected 
  

   in 
  1912, 
  showing 
  that 
  the 
  spread 
  of 
  the 
  froghoppers 
  was 
  restricted 
  

   for 
  the 
  period 
  under 
  review.
