  one 
  female 
  moth, 
  which 
  was 
  depositing 
  eggs, 
  were 
  found 
  where 
  no 
  

   caterpillars 
  had 
  been 
  found 
  since 
  1910 
  and 
  no 
  egg-masses 
  since 
  1911, 
  

   though 
  the 
  trees 
  have 
  been 
  banded 
  each 
  year. 
  The 
  presence 
  of 
  the 
  

   caterpillars 
  is 
  not 
  yet 
  understood, 
  unless 
  it 
  be 
  a 
  reinfestation. 
  Tables 
  

   are 
  given 
  showing 
  the 
  reduction 
  of 
  this 
  pest 
  at 
  Wallingford 
  and 
  Ston- 
  

   ington, 
  according 
  to 
  which 
  there 
  were 
  destroyed 
  at 
  Wallingford 
  in 
  

   1910, 
  8,234 
  egg-masses, 
  8,936 
  caterpillars 
  and 
  96 
  cocoons, 
  numbers 
  

   which 
  in 
  1913 
  were 
  reduced 
  to 
  2 
  egg-masses, 
  3 
  caterpillars 
  and 
  no 
  

   cocoons. 
  At 
  Stonington 
  reduction 
  of 
  the 
  pest 
  is 
  also 
  recorded. 
  In 
  

   1906, 
  73 
  egg-masses, 
  10,000 
  caterpillars 
  and 
  47 
  cocoons 
  were 
  destroyed 
  ; 
  

   in 
  1911, 
  only 
  3 
  egg-masses 
  were 
  found 
  ; 
  and 
  in 
  1912, 
  nothing 
  at 
  all 
  ; 
  

   in 
  1913 
  there 
  was 
  an 
  increase, 
  5 
  caterpillars 
  and 
  one 
  cocoon 
  being 
  

   discovered. 
  

  

  The 
  result 
  of 
  control 
  measures 
  against 
  the 
  brown-tail 
  moth 
  in 
  

   Connecticut 
  during 
  the 
  past 
  winter 
  indicates 
  that 
  the 
  area 
  known 
  to 
  

   be 
  infested 
  has 
  been 
  greatly 
  increased 
  since 
  last 
  year 
  and 
  now 
  includes 
  

   over 
  27 
  towns. 
  In 
  this 
  paper 
  the 
  towns 
  are 
  given 
  with 
  the 
  details 
  and 
  

   results 
  of 
  scouting. 
  The 
  number 
  of 
  nests 
  have 
  slightly 
  increased 
  in 
  

   some 
  of 
  the 
  towns 
  and 
  others 
  are 
  infested 
  only 
  to 
  a 
  slight 
  degree. 
  

   In 
  addition, 
  large 
  infestations 
  were 
  found 
  at 
  Hartford 
  and 
  Suffield. 
  

   In 
  this 
  work 
  open 
  country 
  was 
  carefully 
  examined 
  and 
  particular 
  

   attention 
  given 
  to 
  the 
  fruit 
  trees 
  in 
  orchards, 
  around 
  dwelling-houses 
  

   and 
  along 
  the 
  highways. 
  The 
  brown-tail 
  moth 
  also 
  attacks 
  oak 
  trees 
  

   in 
  the 
  woodlands, 
  but 
  on 
  account 
  of 
  the 
  leaves 
  hanging 
  on 
  these 
  trees 
  

   it 
  is 
  almost 
  impossible 
  to 
  detect 
  the 
  nests, 
  and 
  moreover 
  many 
  of 
  them 
  

   are 
  very 
  far 
  from 
  the 
  ground 
  and 
  it 
  would 
  be 
  very 
  expensive 
  to 
  reach 
  

   them. 
  For 
  these 
  reasons 
  it 
  is 
  impracticable 
  to 
  scout 
  the 
  entire 
  State 
  

   and 
  destroy 
  the 
  nests. 
  A 
  table 
  shows 
  the 
  number 
  of 
  nests 
  found 
  and 
  

   destroyed 
  in 
  each 
  town 
  in 
  1913 
  and 
  during 
  the 
  last 
  three 
  years 
  in 
  

   Windham 
  County. 
  In 
  most 
  there 
  is 
  a 
  marked 
  increase 
  in 
  number 
  

   from 
  1912 
  to 
  1913. 
  

  

  On 
  account 
  of 
  the 
  presence 
  of 
  the 
  brown-tail 
  moth 
  in 
  Connecticut 
  

   and 
  the 
  danger 
  of 
  spreading 
  this 
  insect 
  by 
  shipping 
  nursery 
  stock, 
  a 
  

   quarantine 
  was 
  established 
  by 
  the 
  Federal 
  Horticultural 
  Board, 
  

   becoming 
  effective 
  on 
  and 
  after 
  25th 
  November 
  1912. 
  Later 
  on 
  the 
  

   quarantine 
  was 
  extended 
  to 
  take 
  effect 
  on 
  1st 
  August 
  1913 
  to 
  include 
  

   all 
  the 
  present 
  infested 
  area. 
  Nursery 
  stock 
  within 
  this 
  area 
  could 
  

   not 
  be 
  shipped 
  outside 
  of 
  it 
  unless 
  inspected 
  at 
  the 
  time 
  of 
  packing 
  

   and 
  duly 
  certified 
  by 
  a 
  Federal 
  inspector. 
  The 
  infested 
  towns, 
  as 
  

   well 
  as 
  the 
  quarantined 
  area, 
  are 
  shown 
  by 
  a 
  map. 
  The 
  Federal 
  

   authorities, 
  in 
  co-operation 
  with 
  the 
  State 
  of 
  Massachusetts, 
  have 
  

   imported 
  into 
  the 
  country 
  all 
  the 
  parasites 
  known 
  to 
  attack 
  both 
  the 
  

   gipsy 
  and 
  brown-tail 
  moths 
  in 
  the 
  various 
  European 
  and 
  Asiatic 
  

   countries 
  where 
  these 
  moths 
  occur. 
  The 
  control 
  of 
  this 
  pest 
  by 
  its 
  

   natural 
  enemies 
  is 
  one 
  of 
  the 
  most 
  promising 
  methods. 
  One 
  of 
  the 
  

   most 
  effective 
  of 
  the 
  introduced 
  parasites 
  is 
  an 
  Ichneumonid, 
  Apanteles 
  

   lacteicolor, 
  Vier., 
  which 
  attacks 
  the 
  hibernating 
  caterpillars. 
  A 
  

   Tachinid, 
  Compsilura 
  concinnata, 
  Mg., 
  parasitises 
  both 
  the 
  gipsy 
  and 
  

   brown-tail 
  caterpillars 
  and 
  seems 
  to 
  be 
  well 
  established 
  and 
  spreading 
  

   freely 
  in 
  Massachusetts. 
  The 
  planting 
  of 
  these 
  along 
  the 
  

   boundary 
  of 
  the 
  infestation 
  will 
  doubtless 
  reduce 
  the 
  numbers 
  

   of 
  brown-tail 
  moths 
  and 
  thus 
  check 
  their 
  spread 
  southward 
  and 
  

   westward. 
  Apanteles 
  also 
  attacks 
  caterpillars 
  of 
  the 
  genera 
  Datana
