  parasitised 
  by 
  a 
  Chalcid. 
  

   Stictococcus 
  gowdeyi, 
  Newst., 
  attacks 
  the 
  young 
  shoots, 
  and 
  is 
  rather 
  

   difficult 
  to 
  kill 
  without 
  using 
  insecticides 
  at 
  such 
  strengths 
  as 
  to 
  affect 
  

   the 
  foliage. 
  A 
  large 
  percentage 
  of 
  Pulvinaria 
  psidii.

   sitised. 
  Ceroplastes 
  ceriferus,

  in 
  addition

  The 
  

   Mediterranean 
  Fruit 
  Fly 
  {Ceratitis 
  capitata, 
  Wied.) 
  in 
  Uganda 
  

   breeds 
  throughout 
  the 
  year, 
  some 
  kind 
  of 
  food 
  being 
  always 
  available. 
  

   It 
  has 
  been 
  bred 
  from 
  Anona 
  muricata, 
  banana, 
  coffee 
  berries, 
  guava, 
  

   lemon, 
  orange, 
  pine-apple 
  and 
  papaya.

  and 
  Gryllotalpa

  the 
  latter 
  is 
  the 
  V^ 
  

  

  more 
  destructive, 
  particularly 
  so 
  in 
  nurseries 
  with 
  heavy 
  shading. 
  

   The 
  Coffee 
  Beetle 
  (Stephanoderes 
  Coffeae,

  is 
  reported 
  to 
  be 
  

   causing 
  less 
  loss 
  to

  Insects 
  attacking 
  Cacao. 
  — 
  The 
  scale-insects 
  {Stictococcus 
  dimorfhus, 
  

   Newst.) 
  were 
  parasitised 
  to 
  a 
  greater 
  extent 
  this 
  year 
  by 
  the 
  Noctuid 
  

   moth, 
  Euhlemma 
  costimacula, 
  Saalm. 
  Experiments 
  showed 
  that 
  a 
  

   spray 
  of 
  20 
  per 
  cent, 
  solution 
  of 
  borax 
  was 
  most 
  effective. 
  Plant 
  lice 
  

   (Aphis 
  sp.) 
  have 
  only 
  been 
  observed 
  to 
  attack 
  cacao 
  from 
  about 
  one 
  

   to 
  two-and-a-half 
  years 
  old, 
  grown 
  under 
  heavy 
  shade 
  of 
  bananas. 
  

   They 
  attack 
  the 
  undersides 
  of 
  the 
  young 
  terminal 
  leaves 
  and 
  form 
  a 
  

   cabbage-like 
  mass. 
  They 
  are 
  always 
  associated 
  with 
  an 
  ant. 
  This 
  

   aphis 
  is 
  preyed 
  on 
  by 
  the 
  Mantids, 
  Sphodromantis 
  lineola, 
  Burm., 
  and 
  y 
  

  

  Pseudocreobotra 
  wahlbergi, 
  Stal. 
  The 
  crickets 
  (Gryllotalpa 
  africana, 
  \ 
  / 
  

   P. 
  de 
  B., 
  and 
  Gryllus 
  bimaculatus, 
  de 
  G.) 
  are 
  eaten 
  by 
  the 
  natives, 
  and 
  ^ 
  

   hand-collecting 
  has 
  proved 
  successful. 
  The 
  operation 
  can 
  be 
  carried 
  

   out 
  most 
  satisfactorily 
  by 
  providing 
  hiding 
  places 
  in 
  the 
  nurseries, 
  

   such 
  as 
  grass 
  or 
  pieces 
  of 
  banana 
  leaves, 
  under 
  which 
  the 
  crickets 
  will 
  

   hide 
  during 
  the 
  day, 
  and 
  can 
  then 
  be 
  easily 
  collected. 
  The 
  habits 
  of 
  

   the 
  Cacao 
  Fruit 
  Fly 
  {Ceratitis 
  punctata, 
  Wied.) 
  are 
  similar 
  to 
  those 
  of 
  

   the 
  Mediterranean 
  Fruit 
  Fly. 
  Ripe 
  fruit 
  is 
  necessary 
  for 
  the 
  eggs 
  to 
  

   hatch 
  ; 
  if, 
  therefore, 
  the 
  cacao 
  pods 
  are 
  picked 
  as 
  soon 
  as 
  ripe 
  the 
  

   maggots 
  will 
  not 
  be 
  fully 
  grown, 
  thus 
  reducing 
  the 
  number 
  of 
  the 
  

   adults 
  to 
  infect 
  the 
  next 
  crop. 
  The 
  Cacao 
  Beetle 
  {Adoretus 
  hirtellus, 
  

   Castn.) 
  seriously 
  injures 
  young 
  trees 
  under 
  about 
  three 
  years 
  old.

  at 
  the 
  rate 
  of 
  3 
  lb. 
  to 
  50 
  gallons 
  of 
  water, 
  

   and 
  of 
  chromate 
  of 
  lead 
  at 
  the 
  rate 
  of 
  2 
  oz. 
  to 
  4 
  gallons 
  of 
  water 
  are 
  

   valuable 
  insecticides, 
  and 
  withstand 
  heavy 
  rains. 
  

  

  Insects 
  attacking 
  Cotton. 
  — 
  The 
  Cotton 
  Stainers 
  recorded 
  are 
  Dysdercus 
  

   nigrofasciatus, 
  Stal, 
  D. 
  pretiosus, 
  Dist., 
  Oxycarenus 
  gossypinus,

   0. 
  hyalipennis, 
  Costa. 
  No 
  report 
  was 
  received 
  of 
  damage 
  caused 
  by 
  

   Boll 
  worm 
  {Earias 
  insulana, 
  Boisd). 
  Only 
  isolated 
  plants 
  were 
  

   attacked 
  by 
  scale-insects 
  {Pidvinaria 
  jacksoni, 
  Newst.) 
  Several 
  

   specimens 
  of 
  the 
  parasite, 
  Tetrastichus 
  gowdeyi, 
  Crawf., 
  were 
  bred 
  from 
  

   this 
  scale. 
  

  

  Insects 
  attacking 
  Tea. 
  — 
  A 
  scale-insect

  the

  leaves 
  and 
  covers 
  them. 
  

   Ceroplastes

  has 
  not 
  been 
  found 
  to 
  be 
  a 
  serious 
  pest. 
  

  

  The 
  report 
  concludes 
  with 
  two 
  tables 
  showing 
  a 
  list 
  of 
  25 
  species 
  of 
  

   ticks 
  found 
  in 
  Uganda, 
  together 
  with 
  their 
  hosts 
  and 
  the 
  diseases 
  that 
  

   they 
  transmit.
