  Very 
  few 
  parasites 
  are 
  found 
  in 
  Isfara 
  and 
  only 
  a 
  few 
  larvae 
  of 
  an 
  

   as 
  yet 
  unidentified 
  Tachinid 
  have 
  been 
  reared 
  from 
  some 
  1,000 
  

   pupae 
  of 
  B. 
  cinerarius 
  and 
  C. 
  subtilis. 
  In 
  the 
  neighbouring 
  district 
  

   of 
  Tcharku, 
  on 
  the 
  contrary, 
  these 
  parasites 
  are 
  numerous, 
  and 
  it 
  is 
  

   thought 
  probable 
  that 
  their 
  abundance 
  in 
  Tcharku 
  is 
  due 
  to 
  the 
  

   presence 
  of 
  the 
  caterpillars 
  of 
  Lymantria 
  dispar, 
  which 
  appear 
  later 
  

   than 
  those 
  of 
  the 
  peach-pests 
  and 
  thus 
  provide 
  a 
  means 
  for 
  the 
  develop- 
  

   ment 
  of 
  a 
  second 
  generation 
  of 
  Tachinids. 
  

  

  In 
  discussing 
  remedies 
  against 
  all 
  these 
  pests, 
  the 
  local 
  difficulties 
  

   experienced, 
  owing 
  to 
  the 
  ignorance 
  and 
  suspicion 
  of 
  the 
  natives, 
  are 
  

   enlarged 
  upon. 
  The 
  remedies 
  recommended 
  include 
  : 
  — 
  Sticky 
  belts 
  

   against 
  Rhynchites 
  auratus, 
  which 
  must 
  be 
  frequently 
  renewed 
  as 
  

   they 
  soon 
  become 
  dry 
  from 
  the 
  heat 
  ; 
  owing 
  to 
  the 
  rough 
  surface 
  of 
  

   the 
  trunk 
  of 
  peach 
  trees 
  in 
  Isfara, 
  the 
  sticky 
  material 
  cannot 
  be 
  

   smeared 
  directly 
  on 
  them, 
  but 
  on 
  strips 
  of 
  paper 
  placed 
  on 
  the 
  tree, 
  

   after 
  the 
  cracks, 
  etc., 
  have 
  been 
  filled 
  with 
  clay 
  ; 
  the 
  digging 
  out 
  and 
  

   destruction 
  of 
  the 
  pupae 
  of 
  the 
  Geometridae, 
  which 
  can 
  be 
  done 
  

   during 
  the 
  whole 
  summer 
  and 
  winter, 
  and 
  of 
  those 
  of 
  C. 
  subtilis, 
  which 
  

   must 
  be 
  done 
  in 
  May 
  ; 
  spraying 
  with 
  Paris 
  green 
  and 
  djipsin.

  Thorn 
  hedges 
  in 
  the 
  Seine-Inferieure 
  have 
  been 
  stripped 
  by 
  Hypono- 
  

   meuta 
  cognatellus, 
  except 
  those 
  of 
  the 
  Laboratoire 
  d'Entomologie 
  

   agricole, 
  where 
  the 
  author 
  adopted 
  the 
  simple 
  procedure 
  of 
  pruning 
  

   after 
  the 
  10th 
  or 
  15th 
  August 
  and 
  carefully 
  burning 
  the 
  debris. 
  H. 
  cog- 
  

   natellus 
  usually 
  oviposits 
  on 
  the 
  terminal 
  leaves 
  of 
  the 
  longer 
  twigs, 
  

   and 
  pruning 
  in 
  June 
  would 
  chiefly 
  remove 
  these 
  twigs, 
  thus 
  

   causing 
  the 
  moth 
  to 
  oviposit 
  inside 
  the 
  hedge. 
  If, 
  however, 
  the 
  work 
  

   is 
  done 
  at 
  the 
  time 
  indicated, 
  all 
  the 
  eggs 
  will 
  be 
  destroyed. 
  Pruning 
  

   must 
  therefore 
  be 
  done 
  after 
  the 
  15th 
  August 
  and 
  in 
  February, 
  before 
  

   new 
  growth 
  begins. 
  Large 
  quantities 
  of 
  Hyponomeuta 
  pupae 
  were 
  

   collected 
  and 
  kept 
  under 
  glass 
  bell- 
  jars. 
  Many 
  hundreds 
  of 
  Ichneu- 
  

   mons 
  hatched 
  out 
  between 
  the 
  7th 
  and 
  11th 
  July 
  and 
  by 
  simply 
  

   hfting 
  the 
  bell-jars 
  once 
  daily 
  these 
  were 
  set 
  free. 
  

  

  Hyponomeuta 
  malinellus 
  was 
  controlled 
  by 
  spraying 
  with 
  a 
  

   solution 
  of 
  copper 
  arsenite 
  or 
  Scheele's 
  green 
  made 
  up 
  by 
  mixing 
  

   together 
  3J 
  oz. 
  of 
  the 
  copper 
  salt 
  and 
  35 
  oz. 
  of 
  wheat 
  flour 
  with 
  a 
  Uttle 
  

   water, 
  the 
  flour 
  helping 
  to 
  keep 
  the 
  copper 
  in 
  suspension 
  in 
  the 
  solution; 
  

   this 
  paste 
  is 
  then 
  dissolved 
  in 
  22 
  gallons 
  of 
  water. 
  Apple-trees 
  

   sprayed 
  with 
  the 
  solution 
  remained 
  in 
  perfect 
  condition, 
  whilst 
  non- 
  

   treated 
  trees 
  near 
  by 
  were 
  seriously 
  attacked. 
  An 
  increase 
  of 
  the 
  

   copper 
  from 
  3J 
  oz. 
  to 
  8| 
  oz. 
  led 
  to 
  slight 
  injury 
  to 
  the 
  trees. 
  Spraying 
  

   must 
  be 
  effected 
  early 
  in 
  June, 
  as 
  soon 
  as 
  the 
  caterpillars 
  hatch 
  and 
  

   before 
  they 
  have 
  time 
  to 
  do 
  much 
  damage.
