  eggs 
  in 
  spring, 
  many 
  of 
  the 
  species 
  developing 
  several 
  generations 
  during 
  

   the 
  season. 
  The 
  adults 
  are 
  attracted 
  to 
  light, 
  and 
  many 
  thousands 
  are 
  

   sometimes 
  found 
  in 
  the 
  globes 
  of 
  electric 
  lamps 
  near 
  cities 
  and 
  towns; 
  

   but 
  we 
  have 
  not 
  found 
  it 
  practical 
  to 
  prevent 
  injury 
  by 
  thus 
  trapping 
  them. 
  

  

  Remedial 
  measures 
  are, 
  in 
  general, 
  cleaning 
  up 
  the 
  rubbish 
  in 
  which 
  

   they 
  hibernate, 
  capturing 
  them 
  on 
  sticky 
  surfaces, 
  and 
  spraying 
  with 
  

   some 
  contact 
  insecticide. 
  The 
  first 
  method 
  needs 
  no 
  explanation. 
  Cap- 
  

   turing 
  on 
  sticky 
  surfaces 
  is 
  much 
  resorted 
  to 
  in 
  vineyards, 
  sometimes 
  

   merely 
  with 
  palm-leaf 
  fans 
  coated 
  with 
  tar 
  or 
  "tanglefoot," 
  sometimes 
  

   with 
  elaborate 
  screens 
  run 
  between 
  the 
  rows, 
  the 
  vines 
  being 
  jarred 
  to 
  

   induce 
  the 
  insects 
  to 
  jump 
  or 
  fly. 
  Persistently 
  employed 
  this 
  method 
  de- 
  

   stroys 
  immense 
  numbers, 
  and 
  if 
  begun 
  early 
  in 
  the 
  season 
  will 
  secure 
  

   practical 
  exemption 
  in 
  fall. 
  

  

  Spraying 
  is 
  with 
  either 
  kerosene 
  emulsion 
  or 
  fish 
  oil 
  soaps. 
  The 
  mix- 
  

   ture 
  should 
  always 
  be 
  made 
  as 
  strong 
  as 
  the 
  foliage 
  will 
  stand, 
  the 
  spray 
  

   should 
  be 
  very 
  fine 
  and 
  should 
  be 
  applied 
  with 
  as 
  much 
  force 
  as 
  possible 
  

   so 
  as 
  to 
  reach 
  the 
  partly-grown 
  insects 
  which 
  tend 
  to 
  crouch 
  close 
  to 
  sur- 
  

   face 
  among 
  the 
  plant 
  hairs; 
  and 
  it 
  is 
  also 
  desirable 
  to 
  keep 
  the 
  air 
  about 
  

   the 
  vines 
  or 
  plants 
  filled 
  with 
  the 
  fine 
  mist 
  so 
  as 
  to 
  reach 
  the 
  adults 
  that 
  

   tend 
  to 
  fiy 
  at 
  the 
  first 
  disturbance. 
  In 
  general 
  the 
  toll 
  exacted 
  by 
  these 
  

   Jeaf-hoppers 
  is 
  not 
  appreciated 
  by 
  the 
  agriculturist.
