  Amongst 
  the 
  pests 
  of 
  peaches 
  in 
  the 
  Argentine, 
  the 
  author 
  names 
  

   Aulacaspis 
  pentagona, 
  and 
  recommends 
  for 
  its 
  destruction 
  neutral 
  

   " 
  Acaroina," 
  4J 
  per 
  cent, 
  solution 
  in 
  summer 
  and 
  15 
  to 
  20 
  percent, 
  in 
  

   winter. 
  Calcium 
  sulphides 
  may 
  also 
  be 
  used 
  in 
  winter, 
  being 
  prepared 
  

   by 
  boiling 
  12 
  lb. 
  of 
  lime 
  in 
  4 
  gals, 
  of 
  water 
  and 
  adding 
  8 
  lb. 
  of 
  sulphur 
  

   in 
  powder 
  ; 
  4 
  gals, 
  of 
  water 
  are 
  then 
  added, 
  and 
  the 
  whole 
  boiled 
  for 
  

   two 
  hours. 
  Both 
  preparations 
  should 
  be 
  laid 
  on 
  with 
  hard 
  brushes, 
  

   but 
  sprayers 
  may 
  be 
  used 
  for 
  the 
  upper 
  parts 
  of 
  the 
  trees. 
  Attempts 
  

   are 
  being 
  made 
  to 
  acclimatise 
  certain 
  enemies 
  of 
  the 
  scale, 
  especially 
  

   the 
  Coccinellid, 
  Rhizobius 
  lophantae, 
  and 
  various 
  Chalcids 
  of 
  the 
  genus 
  

   Prospaltella. 
  There 
  i^ 
  a 
  native 
  Coccinellid 
  {Coccidophilus 
  citricus) 
  

   which 
  is 
  generally 
  to 
  be 
  found 
  in 
  summer 
  on 
  lemon 
  and 
  orange 
  trees 
  

   in 
  the 
  province 
  of 
  Buenos 
  Aires, 
  and 
  appears 
  to 
  feed 
  upon 
  Lepidosaphes 
  

   beckii, 
  which 
  is 
  a 
  pest 
  of 
  these 
  plants. 
  It 
  has 
  also 
  been 
  observed 
  o 
  

   have 
  a 
  predilection 
  ioi 
  Aulacaspis 
  (Diaspis). 
  The 
  artificial 
  propagation 
  

   of 
  this 
  insect 
  is 
  advocated. 
  

  

  Aphis 
  persicae 
  (the 
  peach 
  aphis) 
  attacks 
  the 
  tender 
  shoots 
  and 
  leaves, 
  

   kilHng 
  them 
  and 
  thereby 
  causing 
  the 
  death 
  of 
  the 
  tree. 
  It 
  can 
  be 
  

   controlled 
  by 
  spraying 
  the 
  affected 
  parts 
  in 
  spring 
  with 
  a 
  5 
  per 
  cent, 
  

   extract 
  of 
  tobacco. 
  The 
  operation 
  should 
  be 
  carried 
  out 
  in 
  the 
  evening 
  

   and 
  again 
  on 
  the 
  following 
  morning. 
  The 
  tree 
  should 
  subsequently 
  

   be 
  sprayed 
  with 
  water 
  in 
  order 
  to 
  remove 
  the 
  nicotin. 
  A 
  5 
  per 
  cent, 
  

   solution 
  of 
  lysol 
  with 
  0'6 
  per 
  cent, 
  of 
  soft 
  soap 
  in 
  water 
  may 
  also 
  be 
  

   used. 
  It 
  is 
  useful 
  in 
  winter 
  to 
  brush 
  the 
  trunks 
  of 
  the 
  principal 
  

   branches 
  with 
  milk 
  of 
  lime. 
  The 
  plants 
  that 
  have 
  been 
  attacked 
  in 
  

   the 
  previous 
  spring 
  and 
  summer, 
  and 
  especially 
  the 
  ends 
  of 
  the 
  one- 
  

   year-old 
  branches, 
  should 
  be 
  washed 
  in 
  every 
  part 
  with 
  a 
  3 
  per 
  cent, 
  

   solution 
  of 
  soft 
  soap. 
  It 
  is 
  also 
  desirable 
  to 
  collect 
  and 
  destroy 
  the 
  

   tips 
  of 
  badly 
  attacked 
  branches, 
  and 
  all 
  trimmings 
  and 
  pmnings.
