  con- 
  

   taining 
  larvae. 
  All 
  infested 
  parts 
  of 
  the 
  plant 
  should 
  be 
  destroyed 
  

   as 
  well 
  as 
  uncultivated 
  malvaceous 
  plants, 
  for 
  which 
  a 
  search 
  should 
  

   be 
  made 
  in 
  the 
  vicinity 
  of 
  the 
  cotton 
  field. 
  Three 
  Nitidulidae, 
  

   Carpophilus 
  mutillatus, 
  Erich., 
  C. 
  binotatus, 
  Murr., 
  and 
  C. 
  luridus, 
  

   Murr., 
  feed 
  upon 
  the 
  decaying 
  tissues 
  in 
  the 
  bores 
  of 
  the 
  bollworms. 
  

   The 
  four 
  cotton 
  stainers 
  recorded 
  are 
  Dysdercus 
  nigrofasciatus, 
  Stal, 
  

   D. 
  pretiosus, 
  Dist., 
  Oxycarenus 
  hyalinipennis,

   Dist. 
  The 
  leaf-footed 
  plant 
  bug, 
  Leptoglossus 
  membmnaceus, 
  F., 
  

   attacks 
  the 
  seed 
  of 
  cotton, 
  but 
  clean 
  cultivation 
  and 
  the 
  destruction 
  

   of 
  the 
  uncultivated 
  food-plants 
  (three 
  species 
  of 
  Cucurbitaceae) 
  in 
  the 
  

   vicinity 
  of 
  the 
  cotton 
  plots 
  should 
  prevent 
  damage. 
  Of 
  the 
  six 
  

   CocciNELLiDAE 
  found 
  preying 
  on 
  Aphis 
  gossypii, 
  Glov., 
  the 
  following 
  

   are 
  recorded 
  : 
  — 
  Chilomenes 
  lunata, 
  F., 
  Solanophila 
  bosci, 
  Ws., 
  

   Epiladina 
  chrysomelina, 
  F, 
  var., 
  Chilocorus 
  angolensis, 
  Cr. 
  A 
  small 
  

   swarm 
  of 
  Zonocerus 
  variegatus, 
  L., 
  on 
  cotton 
  was 
  easily 
  checked 
  by 
  

   using 
  Paris 
  green 
  applied 
  in 
  a 
  powder. 
  

  

  Few 
  reports 
  were 
  received 
  of 
  damage 
  by 
  the 
  cacao 
  beetle 
  (Adoretus 
  

   hirtellus, 
  Castn.), 
  while 
  the 
  whale-oil 
  soap 
  treatment 
  controlled 
  Toxo- 
  

   ptera 
  theobromae, 
  Schout. 
  Stictococcus 
  dimorphus, 
  Newst., 
  and 
  Pseudo- 
  

   coccus 
  (Dactylopius) 
  sp. 
  are 
  the 
  only 
  two 
  Coccids 
  known 
  to 
  attack 
  

   cacao 
  in 
  Uganda. 
  Gryllus 
  gracilipes, 
  Sauss., 
  is 
  very 
  similar 
  in 
  its 
  

   habits 
  to 
  G. 
  bimaculatus, 
  already 
  referred 
  to 
  as 
  attacking 
  coffee, 
  and 
  

   these 
  two 
  species 
  as 
  well 
  as 
  Gryllotalpa 
  africana 
  are 
  recorded 
  as 
  

   attacking 
  cacao. 
  A 
  millipede 
  of 
  the 
  genus 
  Odontopyge 
  attacked 
  

   freshly 
  planted 
  cacao 
  beans 
  and 
  very 
  young 
  seedlings 
  ; 
  the 
  beans 
  

   should 
  be 
  soaked 
  in 
  a 
  solution 
  of 
  corrosive 
  subHmate 
  (1 
  : 
  1,000) 
  for 
  

   one 
  hour 
  as 
  a 
  preventive. 
  

  

  Among 
  rubber 
  pests 
  the 
  larvae 
  of 
  Glyphodes 
  ocellata, 
  Hmp., 
  eat 
  

   tips 
  and 
  margins 
  of 
  the 
  leaves 
  of 
  Funtumia 
  elastica 
  and 
  F. 
  latifolia 
  

   and 
  pupate 
  within 
  the 
  rolled 
  leaf 
  margins. 
  Pulvinaria 
  psidii, 
  Mask., 
  

   attacks 
  F. 
  elastica, 
  and 
  Chionaspis 
  funtumiae, 
  Newst., 
  F. 
  latifolia, 
  

   while 
  two 
  other 
  undetermined 
  scale-insects 
  attack 
  Ceara 
  and 
  Para 
  

   rubber. 
  Xyleborus 
  confusus, 
  Erich., 
  X. 
  affinis, 
  Erich., 
  and 
  X. 
  cameru- 
  

   nus, 
  Haged., 
  attack 
  Para 
  rubber 
  trees 
  at 
  the 
  tapping 
  cicatrices, 
  but 
  

   may 
  be 
  kept 
  away 
  by 
  painting 
  the 
  trunk 
  with 
  coal 
  tar. 
  

  

  A 
  list 
  is 
  given 
  of 
  the 
  insects 
  which 
  were 
  of 
  economic 
  importance 
  

   during 
  the 
  year, 
  together 
  with 
  the 
  plants 
  attacked. 
  

  

  The 
  amount 
  of 
  Anaphe 
  silk 
  exported 
  during 
  1913-14 
  was 
  about 
  

   12 
  tons, 
  but 
  this 
  figure 
  is 
  not 
  indicative 
  of 
  the 
  growth 
  of 
  the 
  industry.
