  The 
  Cherry 
  Fruit 
  Fly 
  (Rhagoletis 
  cerasi, 
  L.) 
  has 
  been 
  known 
  on 
  the 
  

   Continent 
  for 
  a 
  long 
  time 
  ; 
  but 
  English 
  cherries 
  do 
  not 
  appear 
  to 
  have 
  

   ever 
  been 
  attacked. 
  Affected 
  cherries 
  are, 
  however, 
  constantly 
  

   imported 
  into 
  England, 
  and 
  in 
  consequence 
  it 
  is 
  not 
  impossible 
  that 
  

   the 
  pest 
  may 
  at 
  any 
  time 
  establish 
  itself 
  in 
  this 
  country. 
  Theobald 
  

   says 
  that 
  should 
  it 
  become 
  noticeable 
  in 
  any 
  plantation 
  or 
  garden, 
  it 
  

   would 
  be 
  wise 
  to 
  forego 
  the 
  crop 
  by 
  having 
  the 
  fruit 
  destroyed 
  to 
  

   prevent 
  damage 
  another 
  year, 
  and 
  the 
  possible 
  spread 
  to 
  other 
  plan- 
  

   tations. 
  

  

  The 
  Cherry 
  Fly 
  may 
  be 
  combated 
  by 
  the 
  collection 
  and 
  destruction 
  

   of 
  afiected 
  cherries 
  ; 
  giving 
  poultry 
  the 
  opportunity 
  of 
  picking 
  up 
  

   fallen 
  cherries 
  and 
  maggots, 
  as 
  well 
  as 
  pupae 
  in 
  the 
  soil 
  ; 
  combined 
  

   with 
  surface 
  cultivation 
  in 
  autumn 
  and 
  winter, 
  to 
  expose 
  the 
  pupae 
  

   to 
  birds 
  and 
  the 
  rigours 
  of 
  the 
  weather.

  An 
  increase 
  of 
  the 
  Pentatomid 
  Bug, 
  Empicoris 
  variolosus, 
  is 
  reported. 
  

   These 
  are 
  difficult 
  to 
  detect, 
  as 
  during 
  the 
  day 
  they 
  hide 
  in 
  depressions 
  

   of 
  the 
  bark, 
  old 
  tapping 
  wounds, 
  etc. 
  It 
  is 
  supposed 
  that 
  they 
  cause 
  

   exudation 
  of 
  the 
  latex 
  from 
  young 
  green 
  shoots 
  by 
  sucking 
  them. 
  

   The 
  matter 
  is 
  under 
  investigation.
