  attached 
  to 
  the 
  twigs, 
  often 
  in 
  a 
  

   crevice 
  or 
  crotch. 
  These 
  nests 
  are 
  

   made 
  of 
  pieces 
  of 
  leaves 
  or 
  bark 
  

   held 
  together 
  with 
  silk 
  and 
  are 
  

   diiRcnlt 
  to 
  find 
  on 
  the 
  trees. 
  The 
  

   larvae 
  leave 
  them 
  in 
  April, 
  or 
  

   whenever 
  the 
  buds 
  begin 
  to 
  swell 
  

   appreciably, 
  and 
  burrow 
  into 
  the 
  

   expanding 
  buds 
  and 
  into 
  the 
  ter- 
  

   minal 
  shoots, 
  feeding 
  from 
  the 
  in- 
  

   side.

  the 
  opening 
  leaves, 
  and 
  as 
  the 
  foli- 
  

   age 
  surrounding 
  them 
  dries 
  the 
  

   larvae 
  go 
  outside 
  to 
  eat 
  leaves 
  or 
  

   blossoms, 
  retiring 
  to 
  the 
  nests 
  

   when 
  not 
  feeding. 
  These 
  webbed 
  

   nests 
  are 
  often 
  the 
  first 
  indication 
  

   of 
  the 
  presence 
  of 
  the 
  insects. 
  The 
  

   larvae 
  become 
  full-grown 
  in 
  June 
  

   or 
  early 
  in 
  July, 
  when 
  they 
  are 
  

  

  olive-brown 
  with 
  black 
  heads 
  (fig. 
  

   49, 
  ^ 
  ) 
  . 
  They 
  transform 
  to 
  pupae 
  

   in 
  the 
  nests 
  of 
  webbed 
  leaves, 
  and 
  

   the 
  moths 
  appear 
  about 
  3 
  weeks 
  

   later. 
  These 
  are 
  somewhat 
  

   smaller 
  than 
  codling 
  moths, 
  ashy 
  

   gray, 
  with 
  a 
  cream- 
  white 
  band 
  

   across 
  both 
  wings 
  (fig. 
  49, 
  ^) 
  . 
  The 
  

   flattened 
  eggs, 
  similar 
  to 
  those 
  of 
  

   the 
  codling 
  moth, 
  are 
  deposited 
  on 
  

   the 
  leaves 
  and 
  hatch 
  in 
  a 
  week 
  or 
  

   so. 
  The 
  3^oung 
  larvae 
  feed 
  on 
  the 
  

   leaves, 
  protecting 
  themselves 
  with 
  

   silk, 
  and 
  often 
  eat 
  small 
  holes 
  in 
  

   the 
  fruit. 
  In 
  the 
  fall 
  these 
  larvae 
  

   build 
  the 
  hibernacula 
  in 
  which 
  

   they 
  spend 
  the 
  winter. 
  There 
  is 
  

   only 
  one 
  generation 
  a 
  year. 
  

  

  CONTROL 
  

  

  A 
  spray 
  of 
  lead 
  arsenate, 
  3 
  

   pounds 
  to 
  100 
  gallons 
  of 
  water, 
  

   should 
  be 
  applied 
  just 
  as 
  the 
  tips 
  

   of 
  the 
  leaves 
  are 
  pushing 
  out 
  of 
  the 
  

   buds. 
  If 
  the 
  infestation 
  is 
  seri- 
  

   ous, 
  a 
  second 
  application 
  may 
  be 
  

   made 
  a 
  week 
  or 
  10 
  days 
  later. 
  

  

  Lesser 
  Appleworm 
  

  

  The 
  lesser 
  appleworm 
  has 
  re- 
  

   cently 
  been 
  discovered 
  in 
  eastern 
  

   Oregon, 
  where 
  it 
  has 
  been 
  causing 
  

   considerable 
  injury 
  to 
  prunes. 
  It 
  

   has 
  also 
  occurred 
  for 
  some 
  years 
  

   in 
  British 
  Columbia, 
  and 
  is 
  known 
  

   as 
  a 
  serious 
  pest 
  of 
  apple 
  in 
  sec- 
  

   tions 
  of 
  the 
  eastern 
  parts 
  of 
  the 
  

   United 
  States 
  and 
  Canada. 
  The 
  

   egg, 
  larva, 
  and 
  adult 
  moth 
  are 
  

   somewhat 
  similar 
  in 
  appearance 
  to 
  

   the 
  corresponding 
  stages 
  of 
  the 
  

   codling 
  moth, 
  except 
  that 
  they 
  are 
  

   smaller. 
  The 
  habits 
  of 
  the 
  insect 
  

   are 
  also 
  similar. 
  For 
  controlling 
  

   this 
  insect 
  basic 
  lead 
  arsenate 
  at 
  

   the 
  rate 
  of 
  4 
  pounds 
  to 
  100 
  gallons 
  

   of 
  water, 
  to 
  which 
  is 
  aclded 
  3 
  

   quarts 
  of 
  summer-oil 
  emulsion, 
  is 
  

   recommended. 
  This 
  spray 
  should 
  

   be 
  applied 
  when 
  the 
  moths 
  first 
  

   appear. 
  If 
  later 
  applications 
  seem 
  

   to 
  be 
  necessary, 
  the 
  State 
  Exten- 
  

   sion 
  Service 
  should 
  be 
  consulted.
