  To 
  reduce 
  the 
  numbers 
  of 
  this 
  fly 
  infested 
  fruits 
  should 
  

   be 
  buried 
  not 
  less 
  than 
  two 
  feet 
  deep, 
  the 
  soil 
  above 
  them 
  being 
  well 
  

   rammed 
  down. 
  Balanogastris 
  kolae 
  does 
  not 
  interfere 
  with 
  healthy 
  

   kola 
  fruits 
  and 
  if 
  these 
  are 
  collected 
  as 
  soon 
  as 
  ripe 
  no 
  damage 
  will 
  

   occur. 
  

  

  Coconuts 
  were 
  injured 
  at 
  Assuantsi 
  by 
  a 
  rhinoceros 
  beetle 
  {Archon 
  

   centauriis, 
  F.). 
  Collection 
  was 
  found 
  an 
  efficient 
  means 
  of 
  control 
  for 
  

   a 
  time. 
  This 
  beetle 
  has 
  also 
  been 
  reported 
  as 
  breeding 
  in 
  screwpines 
  

   (Pandanus) 
  at 
  Tarkwa. 
  Coccidae 
  have 
  not 
  been 
  very 
  troublesome, 
  

   though 
  Aspidiotus 
  destructor, 
  Sign., 
  heavily 
  infested 
  the 
  coconut 
  

   plantations 
  at 
  Assuantsi. 
  Though 
  much 
  hampered 
  by 
  the 
  dry 
  season, 
  

   the 
  entomogenous 
  red-headed 
  fungus, 
  Sphaerostilbe 
  coccophila, 
  was 
  

   seen 
  destroying 
  the 
  scales. 
  A 
  predaceous 
  lady-bird 
  beetle, 
  Scymniis 
  

   sp., 
  is 
  being 
  established 
  at 
  Assuantsi 
  to 
  help 
  control. 
  Besides 
  the 
  

   above-mentioned 
  fungus, 
  others 
  of 
  the 
  same 
  valuable 
  group, 
  viz., 
  

   Ophionectria 
  coccicola, 
  Aschersonia 
  oxyspora, 
  Aschersonia 
  sp. 
  and 
  an 
  

   undetermined 
  one, 
  have 
  been 
  discovered. 
  The 
  leaves 
  of 
  young 
  

   Funtumia 
  rubber 
  in 
  nurseries 
  are 
  often 
  much 
  injured 
  by 
  the 
  Funtumia 
  

   moth, 
  Glyphodes 
  ocellata, 
  Hmp. 
  Parasites 
  do 
  not 
  appear 
  effective 
  

   in 
  controlling 
  these 
  larvae, 
  as 
  the 
  only 
  one 
  yet 
  found, 
  a 
  Tachinid 
  fly, 
  

   is 
  itself 
  heavily 
  parasitised 
  by 
  a 
  Hymenopteron. 
  The 
  remedies 
  

   therefore 
  available 
  are 
  : 
  (1) 
  the 
  picking 
  or 
  squeezing 
  of 
  infested 
  

   leaves 
  ; 
  (2) 
  the 
  dusting 
  of 
  the 
  dew-moistened 
  leaves 
  with 
  a 
  mixture 
  

   of 
  Paris 
  green 
  1 
  lb. 
  and 
  air-slaked 
  lime 
  6 
  lb. 
  ; 
  (3) 
  spraying 
  with 
  lead 
  

   arsenate, 
  as 
  recommended 
  for 
  the 
  Adoretus 
  beetle 
  of 
  cacao. 
  

  

  The 
  growing 
  crops 
  of 
  corn 
  are 
  not 
  seriously 
  troubled 
  by 
  pests, 
  but 
  

   enormous 
  loss 
  is 
  caused 
  to 
  the 
  harvested 
  grain 
  by 
  the 
  corn 
  weevil, 
  

   Calandra 
  oryzae, 
  L., 
  which 
  starts 
  its 
  ravages 
  with 
  the 
  ripe 
  grain 
  in 
  the 
  

   fields. 
  The 
  author 
  hopes 
  that 
  provision 
  will 
  be 
  made 
  for 
  the 
  

   fumigation 
  of 
  all 
  seeds 
  and 
  plants 
  at 
  the 
  ports. 
  One 
  instance 
  showing 
  

   the 
  need 
  for 
  such 
  a 
  measure 
  is 
  that 
  a 
  small 
  consignment 
  of 
  mango 
  seed 
  

   from 
  Ceylon 
  was 
  found 
  to 
  contain 
  a 
  number 
  of 
  mango-seed 
  weevils,

  Cotton 
  pests. 
  The 
  prompt 
  and 
  vigorous 
  use 
  of 
  Paris 
  green 
  checked 
  

   the 
  ravages 
  of 
  the 
  cotton 
  worm 
  {Alabama 
  argillacea), 
  this 
  being 
  the 
  

   second 
  time 
  since 
  the 
  re-establishment 
  of 
  the 
  cotton 
  industry 
  that 
  

   artificial 
  control 
  was 
  necessary. 
  The 
  pest 
  occurs 
  every 
  year, 
  but 
  is 
  

   combated 
  by 
  its 
  natural 
  enemies, 
  of 
  which 
  the 
  " 
  Jack 
  Spaniard 
  " 
  

   wasp 
  {Polistes 
  annularis) 
  is 
  the 
  most 
  important. 
  In 
  Bequia, 
  one 
  of 
  

   the 
  Cays, 
  where 
  the 
  worm 
  abounds, 
  there 
  are 
  no 
  Jack 
  Spaniards, 
  or 
  at 
  

   least 
  very 
  few. 
  Planters 
  must 
  always 
  be 
  prepared 
  to 
  resort 
  to 
  poisons 
  

   immediately 
  it 
  is 
  found 
  that 
  the 
  caterpillars 
  have 
  not 
  been 
  held 
  in 
  

   check 
  by 
  their 
  natural 
  foes. 
  The 
  freedom 
  from 
  leaf-blister 
  mite 
  

   (Eriophyes 
  gossypii) 
  appears 
  to 
  the 
  author 
  to 
  be 
  the 
  result 
  of 
  extreme 
  

   vigilance 
  on 
  the 
  part 
  of 
  the 
  planters 
  and 
  others 
  concerned 
  in 
  keeping 
  

   down 
  this 
  pest.

  Ordinance

  for 
  the 
  destruction 
  of 
  

   old

  at 
  such 
  a 
  time 
  as 
  to 
  cause 
  a 
  complete 
  break 
  each 
  year 
  in 
  

   the 
  food 
  supply 
  of 
  the 
  mite, 
  seems 
  especially 
  useful.
