  Reporting 
  on 
  the 
  condition 
  of 
  the 
  fruit 
  crop 
  at 
  the 
  end 
  of 
  May 
  for 
  

   the 
  Blenheim 
  district, 
  the 
  author 
  says 
  that 
  as 
  considerable 
  damage 
  

   has 
  been 
  done 
  by 
  leaf-roller 
  caterpillars, 
  he 
  has 
  recommended 
  spraying 
  

   with 
  arsenate 
  of 
  lead 
  until 
  the 
  end 
  of 
  March, 
  it 
  being 
  in 
  that 
  month 
  

   that 
  the 
  pest 
  seems 
  to 
  be 
  at 
  its 
  worst. 
  The 
  fruit 
  should 
  be 
  kept 
  thinned, 
  

   as 
  the 
  pest 
  does 
  most 
  damage 
  where 
  apples 
  are 
  in 
  clusters.

  The 
  author 
  has 
  successfully 
  experimented 
  with 
  a 
  painting 
  mixture 
  

   , 
  containing 
  linseed 
  oil, 
  white 
  lead 
  and 
  turpentine, 
  appHed 
  with 
  a 
  

   moderately 
  stiff 
  brush, 
  but 
  not 
  stiff 
  enough 
  to 
  damage 
  the 
  fruit 
  buds. 
  

   The 
  ingredients 
  are 
  costly, 
  but 
  the 
  author 
  thinks 
  that 
  this 
  is 
  an 
  almost 
  

   certain 
  cure, 
  as 
  the 
  turpentine 
  penetrates 
  the 
  covering 
  of 
  the 
  aphids 
  

   and 
  kills 
  them 
  quickly, 
  while 
  the 
  white 
  lead, 
  besides 
  being 
  poisonous, 
  

   covers 
  the 
  colonies 
  with 
  an 
  airproof 
  coating. 
  A 
  formula 
  has 
  

   not 
  yet 
  been 
  decided 
  upon, 
  but 
  the 
  white 
  lead 
  should 
  be 
  mixed 
  with 
  

   sufficient 
  linseed 
  oil 
  and 
  turpentine 
  to 
  give 
  the 
  mixture 
  a 
  milk-Hke 
  

   consistency.

  Bio-pathological 
  relations 
  are 
  simple 
  between 
  wild 
  host-plants 
  and 
  

   the 
  insects 
  which 
  attack 
  them, 
  but 
  in 
  the 
  case 
  of 
  cultivated 
  species, 
  

   complications 
  are 
  introduced. 
  The 
  biology 
  of 
  Ceratitis 
  has 
  been 
  fully 
  

   studied 
  from 
  an 
  entomological 
  point 
  of 
  view, 
  while 
  the 
  factors 
  con- 
  

   nected 
  with 
  the 
  characteristics 
  of 
  the 
  various 
  species 
  of 
  Citrus, 
  and 
  the 
  

   modifications 
  produced 
  by 
  the 
  grower 
  and 
  the 
  intensity 
  of 
  cultivation, 
  

   are 
  little 
  known. 
  The 
  author 
  considers 
  that 
  local 
  conditions 
  may 
  

   cause 
  such 
  variations 
  in 
  the 
  biological 
  relations 
  between 
  the 
  fly 
  and 
  

   the 
  plant 
  that 
  the 
  attack 
  of 
  the 
  insect 
  may 
  be 
  possible 
  in 
  one 
  region
