  vicinity 
  of 
  Euclid, 
  Ohio. 
  He 
  also 
  reported 
  it 
  as 
  being 
  very 
  injurious 
  

   in 
  vineyards 
  on 
  Kelleys 
  Island, 
  Ohio, 
  in 
  1905. 
  In 
  1906 
  it 
  was 
  

   reported 
  by 
  H. 
  A. 
  Gossard 
  and 
  J. 
  S. 
  Houser 
  as 
  again 
  being 
  very 
  

   injurious 
  in 
  Ohio 
  on 
  Kelleys 
  Island, 
  South 
  and 
  Middle 
  Bass 
  Islands, 
  

   and 
  also 
  in 
  vineyards 
  along 
  Lake 
  Erie 
  east 
  and 
  west 
  of 
  Cleveland. 
  

  

  Prof. 
  Slingerland 
  (loc. 
  cit.) 
  reported 
  that 
  a 
  correspondent 
  informed 
  

   him 
  that 
  the 
  crop 
  was 
  entirely 
  ruined 
  by 
  this 
  insect 
  in 
  some 
  vineyards 
  

   at 
  North 
  East, 
  Pa., 
  in 
  1896. 
  The 
  same 
  author 
  makes 
  the 
  following 
  

   statement 
  in 
  regard 
  to 
  serious 
  infestations 
  in 
  the 
  State 
  of 
  New 
  York: 
  

  

  There 
  are 
  doubtless 
  more 
  or 
  less 
  "wormy" 
  grapes 
  each 
  year 
  in 
  practically 
  every 
  

   vineyard 
  in 
  New 
  York 
  State, 
  so 
  that 
  the 
  grape-berry 
  moth 
  is 
  a 
  constant 
  menace. 
  

   But 
  it 
  seems 
  seldom 
  to 
  have 
  been 
  injurious 
  since 
  1873, 
  when 
  it 
  was 
  first 
  reported 
  as 
  

   increasing 
  in 
  numbers 
  in 
  the 
  Hudson 
  Valley. 
  In 
  1898 
  it 
  was 
  a 
  serious 
  pest 
  in 
  the 
  vine- 
  

   yard 
  of 
  a 
  correspondent 
  at 
  Kendall, 
  N. 
  Y., 
  and 
  in 
  1902 
  reports 
  reached 
  us 
  of 
  its 
  rav- 
  

   ages 
  all 
  through 
  the 
  Chautauqua 
  grapebelt. 
  From 
  portions 
  of 
  some 
  vineyards 
  near 
  

   Brocton 
  [N. 
  Y.], 
  a 
  loss 
  of 
  from 
  25 
  to 
  50 
  per 
  cent 
  was 
  reported, 
  and 
  in 
  one 
  case 
  90 
  per 
  

   cent 
  of 
  the 
  fruit 
  was 
  ruined. 
  

  

  During 
  the 
  investigations 
  of 
  grape 
  insects 
  at 
  North 
  East, 
  Pa., 
  by 
  

   the 
  Bureau 
  of 
  Entomology, 
  the 
  grape-berry 
  moth 
  was 
  found 
  to 
  be 
  

   very 
  injurious 
  over 
  limited 
  vineyard 
  areas 
  in 
  this 
  township 
  in 
  1906, 
  

   1907, 
  and 
  1908. 
  In 
  1909 
  and 
  1910 
  the 
  injury 
  was 
  not 
  so 
  great. 
  In 
  

   1911, 
  however, 
  the 
  infestation 
  was 
  noted 
  to 
  be 
  quite 
  heavy 
  in 
  two 
  

   or 
  three 
  vineyards. 
  Serious 
  injury 
  was 
  also 
  noted 
  in 
  vineyards 
  in 
  

   Ohio 
  along 
  the 
  lake 
  shore 
  east 
  and 
  west 
  of 
  Cleveland, 
  and 
  also 
  near 
  

   Sandusky. 
  

  

  It 
  is 
  evident 
  from 
  these 
  records 
  that 
  this 
  is 
  a 
  serious 
  enemy 
  of 
  the 
  

   grape, 
  of 
  long 
  standing 
  and 
  wide 
  distribution 
  throughout 
  the 
  vine- 
  

   yard 
  areas 
  of 
  the 
  eastern 
  United 
  States. 
  

  

  In 
  the 
  aggregate 
  the 
  crop 
  loss 
  due 
  to 
  its 
  depredations 
  must 
  be 
  very 
  

   great, 
  but 
  owing 
  to 
  the 
  irregularity 
  with 
  which 
  the 
  infestation 
  occurs 
  

   over 
  vineyard 
  areas 
  it 
  is 
  exceedingly 
  difficult 
  to 
  estimate 
  the 
  amount. 
  

   For 
  this 
  reason 
  the 
  insect 
  has 
  not 
  been 
  subject 
  to 
  the 
  persistent 
  and 
  

   painstaking 
  efforts 
  for 
  its 
  control 
  on 
  the 
  part 
  of 
  the 
  vineyardist 
  that 
  

   so 
  destructive 
  an 
  insect 
  pest 
  seems 
  to 
  warrant. 
  

  

  HABITS 
  OF 
  THE 
  ADULT 
  OR 
  MOTH. 
  

  

  The 
  adult 
  grape-berry 
  moth 
  is 
  rarely 
  seen 
  in 
  the 
  vineyard, 
  even 
  in 
  

   locations 
  where 
  it 
  is 
  quite 
  abundant. 
  It 
  is 
  a 
  small 
  slaty-brown 
  moth 
  

   with 
  peculiar 
  shaded 
  brown 
  markings 
  on 
  the 
  forewings 
  which 
  render 
  

   it 
  quite 
  inconspicuous 
  upon 
  the 
  canes 
  of 
  the 
  grapevine. 
  When 
  at 
  rest 
  

   with 
  the 
  wings 
  folded 
  it 
  is 
  about 
  one-fourth 
  of 
  an 
  inch 
  long 
  (see 
  PI. 
  

   IV, 
  fig. 
  2) 
  and 
  measures 
  less 
  than 
  one-half 
  inch 
  across 
  the 
  outspread 
  

   wings 
  (see 
  PI. 
  IV, 
  fig. 
  1). 
  In 
  captivity 
  in 
  the 
  rearing 
  cages 
  the 
  moths 
  

   were 
  inactive 
  during 
  the 
  day, 
  remaining 
  stationary 
  upon 
  the 
  canes- 
  

   of 
  the 
  vine 
  beneath 
  the 
  denser 
  foliage 
  or 
  upon 
  the 
  woodwork 
  of 
  the
