  Many 
  privet 
  hedges 
  in 
  New 
  Haven 
  were 
  attacked 
  during 
  May 
  1913 
  

   by 
  larvae 
  which 
  tied 
  together 
  the 
  terminal 
  leaves, 
  forming 
  an 
  enclosure 
  

   within 
  which 
  they 
  fed. 
  The 
  adult 
  was 
  a 
  Tortricid 
  moth 
  and 
  deter- 
  

   mined 
  by 
  Mr. 
  W. 
  D. 
  Kearfott 
  as 
  Archips 
  rasana, 
  L. 
  This 
  species 
  was 
  

   introduced 
  from 
  Europe, 
  where 
  it 
  has 
  been 
  observed 
  feeding 
  on 
  apple, 
  

   elm. 
  willow, 
  birch, 
  wild 
  rose, 
  raspberry, 
  hazel, 
  linden, 
  aspen, 
  hawthorn, 
  

   currant 
  and 
  gooseberry. 
  The 
  eggs 
  are 
  laid 
  on 
  the 
  tmgs 
  in 
  small 
  

   flattened, 
  oval 
  masses, 
  covered 
  with 
  a 
  dull 
  waxy 
  substance, 
  the 
  masses 
  

   laid 
  in 
  the 
  breeding 
  cages 
  containing 
  from 
  24 
  to 
  81 
  eggs. 
  The 
  eggs 
  

   hatch 
  from 
  about 
  the 
  1st 
  to 
  the 
  middle 
  of 
  May. 
  The 
  larva 
  feeds 
  on 
  

   the 
  tip 
  of 
  the 
  growth 
  where 
  it 
  draws 
  two 
  or 
  more 
  leaves 
  together 
  with 
  

   silk, 
  thus 
  forming 
  an 
  enclosure 
  within 
  which 
  a 
  single 
  larva 
  feeds 
  and 
  

   later 
  pupates. 
  The 
  first 
  pupae 
  were 
  found 
  in 
  the 
  breeding 
  cages 
  on 
  

   3rd 
  June 
  and 
  the 
  first 
  adults 
  on 
  10th 
  June. 
  There 
  is 
  one 
  brood 
  each 
  

   year 
  and 
  the 
  winter 
  is 
  passed 
  in 
  the 
  egg 
  stage. 
  Many 
  larvae 
  had 
  

   eggs 
  of 
  Tachinid 
  flies 
  deposited 
  on 
  the 
  head 
  and 
  first 
  segment 
  of 
  the 
  

   body, 
  and 
  the 
  flies 
  began 
  to 
  emerge 
  from 
  larvae 
  collected 
  on 
  18th 
  June. 
  

   The 
  species 
  was 
  determined 
  as 
  Exorista 
  pyste, 
  Walk. 
  Trimming 
  the 
  

   hedges 
  will 
  remove 
  most 
  of 
  the 
  infested 
  tips 
  which 
  should 
  be 
  gathered 
  

   and 
  destroyed 
  to 
  kill 
  the 
  larvae. 
  Some 
  of 
  the 
  larvae 
  will 
  let 
  them- 
  

   selves 
  down 
  to 
  the 
  ground 
  when 
  disturbed 
  and 
  later 
  return 
  to 
  the 
  plants. 
  

   The 
  hedges 
  should 
  be 
  examined 
  after 
  a 
  few 
  days 
  and 
  any 
  infested 
  tips 
  

   should 
  be 
  removed. 
  Should 
  this 
  insect 
  become 
  troublesome 
  on 
  

   currants 
  and 
  gooseberries, 
  it 
  may 
  be 
  controlled 
  by 
  a 
  thorough 
  spraying 
  

   with 
  lead 
  arsenate 
  at 
  the 
  rate 
  of 
  2 
  lb. 
  in 
  50 
  gals, 
  of 
  water, 
  soon 
  after 
  

   the 
  leaves 
  unfold.

  An

  of 
  an 
  experiment

  a

  the 
  cabbage 
  fly, 
  

   Pegomyia

  is 
  given. 
  Varieties 
  of 
  plants 
  were 
  

   arranged 
  in 
  order 
  and 
  an 
  area 
  selected 
  for 
  special 
  treatment, 
  namely 
  for 
  

   the 
  application 
  of 
  tar 
  paper 
  disks. 
  The 
  disks 
  were 
  cut 
  in 
  the 
  form 
  

   of 
  hexagons, 
  four 
  inches 
  in 
  diameter, 
  from 
  single 
  ply 
  tar 
  paper, 
  and 
  were 
  

   placed 
  on 
  the 
  stems 
  of 
  plants 
  at 
  the 
  time 
  of 
  setting. 
  Some 
  plants 
  

   were 
  then 
  " 
  damping 
  off 
  " 
  and 
  failed 
  to 
  recover 
  ; 
  others 
  were 
  killed 
  

   by 
  the 
  cabbage 
  maggot.

  the 
  plants 
  which 
  remained

   the

  and

  of 
  the 
  disked 
  ones 
  were
