  THE 
  BEAN 
  THKIPS. 
  

  

  A 
  simpler 
  formula 
  and 
  one 
  that 
  possibly 
  will 
  act 
  quite 
  as 
  well 
  on 
  

   this 
  insect, 
  where 
  it 
  is 
  exposed 
  on 
  the 
  foliage, 
  and 
  one 
  that 
  will 
  offer 
  

   no 
  chance 
  for 
  the 
  burning 
  of 
  the 
  foliage, 
  has 
  given 
  good 
  results 
  in 
  

   the 
  destruction 
  of 
  Heliothrips 
  rubrocinctus 
  Giard 
  in 
  Florida, 
  Mr. 
  

   Edward 
  Simmonds, 
  of 
  the 
  Bureau 
  of 
  Plant 
  Industry, 
  advised 
  the 
  

   writer 
  that 
  a 
  solution 
  composed 
  of 
  1 
  gallon 
  of 
  blackleaf 
  tobacco 
  ex- 
  

   tract, 
  1 
  pound 
  of 
  whale-oil 
  soap, 
  .and 
  50 
  gallons 
  of 
  water 
  gave 
  excel- 
  

   lent 
  results 
  in 
  treating 
  trees 
  infested 
  by 
  this 
  insect. 
  This 
  formula 
  

   seems 
  a 
  little 
  strong 
  to 
  the 
  writer 
  and 
  he 
  would 
  recommend 
  using 
  the 
  

   blackleaf 
  at 
  the 
  rate 
  of 
  1 
  part 
  to 
  60 
  parts 
  of 
  water. 
  In 
  the 
  place 
  of 
  

   this, 
  a 
  40 
  per 
  cent 
  solution 
  of 
  nicotine 
  can 
  be 
  substituted 
  at 
  the 
  rate 
  

   of 
  1 
  part 
  to 
  from 
  1,000 
  to 
  2,000 
  parts 
  of 
  water. 
  

  

  DISTRIBUTING 
  THE 
  PARASITE. 
  

  

  Possibly 
  the 
  parasite 
  of 
  this 
  insect 
  can 
  be 
  artificially 
  distributed 
  

   with 
  good 
  results 
  to 
  sections 
  infested 
  by 
  this 
  thrips 
  where 
  the 
  para- 
  

   site 
  does 
  not 
  occur. 
  For 
  directions 
  and 
  methods 
  of 
  shipping 
  this 
  

   parasite,

  reader
