  nursery 
  at 
  Pretoria 
  and 
  one 
  at 
  Pietermaritzburg, 
  and 
  had 
  been 
  going 
  

   on 
  at 
  least 
  since 
  1906. 
  The 
  response 
  of 
  the 
  occupiers 
  to 
  the 
  appeal 
  

   for 
  suppressive 
  action 
  was, 
  on 
  the 
  whole, 
  gratifying, 
  but 
  many 
  took 
  no 
  

   action 
  at 
  all, 
  and 
  others 
  sprayed 
  to 
  little 
  effect, 
  probably 
  owing 
  to 
  

   slovenly 
  application. 
  Lime-sulphur 
  wash 
  and 
  '" 
  Scalecide 
  " 
  have 
  

   both 
  proved 
  highly 
  efficient 
  as 
  spraying 
  fluids. 
  One 
  thorough 
  spray- 
  

   ing 
  every 
  winter 
  is 
  evidently 
  all 
  that 
  is 
  required 
  to 
  prevent 
  damage 
  

   to 
  a 
  tree 
  ; 
  but 
  two 
  or 
  three 
  thorough 
  sprayings 
  in 
  one 
  winter 
  may 
  be 
  

   necessary 
  to 
  get 
  the 
  pest 
  well 
  under 
  control 
  in 
  the 
  case 
  of 
  trees 
  which 
  

   have 
  been 
  allowed 
  to 
  become 
  badly 
  infested 
  by 
  neglect 
  in 
  one 
  or 
  more 
  

   years. 
  The 
  measures 
  that 
  the 
  Government 
  is 
  applying 
  to 
  prevent 
  

   the 
  rapid 
  dissemination 
  of 
  the 
  insect 
  are 
  chiefly 
  those 
  relative 
  to 
  

   nurseries 
  and 
  plant 
  traffic, 
  intended 
  to 
  check 
  the 
  spread 
  of 
  plant 
  pests 
  

   in 
  general. 
  Special 
  instructions 
  were 
  given 
  to 
  railway 
  and 
  postal 
  

   officials, 
  who 
  send 
  non-certificated 
  plants 
  to 
  an 
  Agricultural 
  Depart- 
  

   ment 
  plant-inspector 
  for 
  examination 
  before 
  they 
  are 
  forwarded 
  for 
  

   dehvery. 
  Special 
  legislation 
  applies 
  to 
  Pretoria, 
  it 
  being 
  illegal 
  to 
  

   remove 
  any 
  plants 
  from 
  the 
  town 
  without 
  the 
  written 
  permission 
  of 
  

   the 
  Department 
  of 
  Agriculture. 
  It 
  is 
  also 
  illegal 
  to 
  remove 
  any 
  

   woody 
  plants 
  from 
  a 
  property 
  known 
  to 
  be 
  infested 
  "with 
  the 
  insect 
  

   anywhere 
  in 
  the 
  country. 
  A 
  general 
  inspection 
  was 
  made 
  between 
  

   August 
  1911 
  and 
  April 
  1912, 
  and 
  the 
  towns 
  and 
  places 
  where 
  the 
  pest 
  

   was 
  found 
  are 
  given, 
  and 
  in 
  a 
  general 
  way, 
  the 
  position 
  in 
  July 
  1913. 
  

   The 
  towns 
  and 
  places 
  inspected 
  are 
  in 
  the 
  Transvaal, 
  Orange 
  Free 
  

   State 
  and 
  Natal.

  The 
  successful 
  introduction 
  of 
  Novius 
  cardinalis 
  against 
  Icerya 
  

   purchasi, 
  Mask., 
  in 
  the 
  province 
  of 
  Messina 
  and 
  elsewhere, 
  and 
  the 
  

   possibility 
  of 
  obtaining 
  good 
  results 
  with 
  parasites 
  of 
  other 
  injurious 
  

   insects 
  led 
  the 
  Cattedra 
  ambulante 
  d'Agricoltura 
  in 
  Messina 
  to 
  intro- 
  

   duce 
  as 
  many 
  of 
  such 
  enemies 
  as 
  possible. 
  It 
  is 
  due 
  to 
  F. 
  Silvestri 
  

   that 
  the 
  Coccinellids, 
  Rhizobius 
  lophantae, 
  R. 
  ventralis 
  and 
  Orcus 
  

   chalybaeus, 
  which 
  prey 
  upon 
  Chrysomphalus 
  and 
  other 
  injurious 
  Coccids, 
  

   and 
  Hippodamia 
  convergens, 
  an 
  enemy 
  of 
  aphids, 
  have 
  been 
  imported. 
  

   He 
  also 
  brought 
  two 
  other 
  parasites 
  : 
  Galesus 
  silvestrii, 
  Kief, 
  and 
  

   Dirhinus 
  giffardii, 
  Silv., 
  into 
  Italy 
  to 
  combat 
  the 
  Mediterranean 
  fruit 
  fly, 
  

   and 
  then 
  found 
  that 
  they 
  would 
  breed 
  in 
  the 
  olive 
  fly. 
  It 
  is 
  therefore 
  

   hoped 
  that 
  these 
  parasites 
  will 
  be 
  efficient 
  against 
  both 
  these 
  pests 
  in 
  

   peach, 
  orange, 
  and 
  olive-growing 
  districts 
  w^here 
  the 
  soil 
  is 
  loose 
  and 
  

   sandy. 
  As 
  yet 
  it 
  is 
  not 
  known 
  whether 
  the 
  parasites 
  will 
  become 
  

   acclimatised, 
  but 
  from 
  the 
  Naples 
  district, 
  where 
  sohae 
  of 
  them 
  were 
  

   introduced 
  some 
  time 
  ago, 
  the 
  reports 
  are 
  most 
  satisfactory.
