  Oranges

  Province 
  of 
  Chincha 
  (Venezuela) 
  have 
  been 
  attacked 
  

   by 
  Coccids,

  a

  is 
  stated 
  to 
  have 
  

   proved 
  an 
  efficient 
  control. 
  The 
  emulsion 
  is 
  prepared 
  with 
  2 
  parts 
  

   of 
  kerosene 
  and 
  1 
  of 
  a 
  6 
  per

  The 
  resultant 
  

   creamy 
  mixture 
  is

  its 
  bulk 
  of 
  water.

  A 
  serious 
  attack 
  of 
  the 
  apple-sucker, 
  Psylla 
  mali, 
  is 
  recorded 
  in 
  

   the 
  South 
  of 
  England 
  in 
  April 
  and 
  May, 
  which 
  was 
  not 
  unexpected, 
  

   because 
  swarms 
  of 
  the 
  Psylla 
  had 
  been 
  noted 
  in 
  the 
  winter. 
  This 
  

   pest 
  is 
  worst 
  on 
  old 
  trees 
  and 
  generally 
  on 
  varieties 
  with 
  short-stalked 
  

   blossoms 
  ; 
  Beauty 
  of 
  Bath, 
  Lord 
  Derby, 
  Lady 
  Sudeley, 
  Lord 
  

   Grosvenor 
  and 
  Lane's 
  Prince 
  Albert 
  were 
  all 
  severely 
  attacked. 
  

   Capsid 
  bugs 
  are 
  also 
  recorded. 
  [See 
  this 
  Review, 
  Ser. 
  A, 
  ii, 
  p. 
  658]. 
  

   In 
  sprajdng 
  against 
  the 
  apple-sucker, 
  it 
  is 
  better 
  to 
  drench 
  the 
  trees 
  

   with 
  a 
  weak 
  wash 
  than 
  to 
  spray 
  Hghtly 
  with 
  a 
  strong 
  one, 
  the 
  quantity 
  

   of 
  wash 
  used 
  being 
  of 
  more 
  importance 
  than 
  the 
  force 
  apphed. 
  With 
  

   soft 
  water, 
  6 
  lbs. 
  of 
  good 
  soft 
  soap, 
  or 
  with 
  hard 
  water 
  8 
  lbs., 
  to 
  100 
  

   gallons 
  should 
  suffice. 
  Another 
  wash 
  of 
  J 
  fluid 
  oz. 
  of 
  domestic 
  cloudy 
  

   ammonia 
  to 
  the 
  gallon, 
  with 
  the 
  soft 
  soap, 
  is 
  recommended, 
  but 
  

   neither 
  of 
  these 
  washes 
  are 
  completely 
  satisfactory.

  When 
  the 
  mealy 
  bugs 
  Pseudoccus 
  citri 
  and 
  P. 
  longispinus 
  occur 
  

   on 
  vines 
  in 
  May, 
  they 
  are 
  better 
  destroyed 
  by 
  vaporising 
  a 
  49% 
  

   nicotin 
  extract 
  than 
  by 
  cyanides, 
  because 
  young 
  vine 
  leaves 
  are 
  

   very 
  susceptible 
  to 
  the 
  latter. 
  Nicotin 
  of 
  the 
  above 
  strength 
  has 
  been 
  

   used 
  successfully 
  on 
  vines. 
  As 
  the 
  mealy 
  bugs 
  usually 
  appear 
  on 
  the 
  

   young 
  wood 
  of 
  the 
  previous 
  year, 
  it 
  is 
  advisable 
  to 
  cut 
  off 
  the 
  snags 
  

   close 
  to 
  each 
  lateral. 
  Ants 
  in 
  a 
  vinery 
  should 
  be 
  destroyed 
  at 
  once, 
  

   as 
  their 
  presence 
  often 
  precedes 
  an 
  attack 
  of 
  mealy 
  bug.
