  OF 
  STATE 
  ENTOMOLOGIST

  To 
  the 
  Regents 
  of 
  the 
  University 
  of 
  the 
  State 
  of 
  New 
  York 
  

  

  I 
  have 
  the 
  honor 
  of 
  presenting 
  herewith 
  my 
  report 
  on 
  the 
  injurious 
  

   and 
  other 
  insects 
  of 
  the 
  state 
  of 
  New 
  York 
  for 
  the 
  year 
  ending 
  Oct. 
  15, 
  

   1900. 
  

  

  General 
  entomologic 
  features. 
  The 
  excessive 
  depredations 
  of 
  last 
  

   year 
  by 
  the 
  forest 
  tent 
  caterpillar, 
  Clisiocampa 
  disstria 
  Hiibn., 
  

   were 
  somewhat 
  mitigated 
  in 
  1900, 
  though 
  the 
  insect 
  was 
  present 
  in 
  some 
  

   orchards 
  in 
  considerable 
  numbers. 
  It 
  is 
  a 
  pleasure 
  to 
  record 
  that 
  the 
  

   energetic 
  measures 
  employed 
  by 
  various 
  cities 
  and 
  towns 
  last 
  year 
  bore 
  

   fruit 
  this 
  season 
  in 
  the 
  comparative 
  immunity 
  of 
  these 
  places 
  from 
  the 
  pest. 
  

   The 
  elm 
  leaf 
  beetle, 
  Galerucella 
  luteola 
  Mull., 
  has 
  been 
  kept 
  well 
  

   under 
  control 
  in 
  Albany 
  and 
  Troy 
  by 
  intelligent 
  and 
  systematic 
  spraying, 
  

   showing 
  that 
  it 
  is 
  practicable 
  to 
  prevent 
  serious 
  injury 
  by 
  this 
  pest. 
  ^It 
  

   has 
  established 
  itself 
  in 
  several 
  localities 
  in 
  the 
  western 
  part 
  of 
  the 
  state, 
  

   and 
  it 
  may 
  prove 
  as 
  injurious 
  there 
  as 
  it 
  has 
  been 
  in 
  the 
  Hudson 
  river 
  

   valley. 
  It 
  is 
  a 
  source 
  of 
  deep 
  regret 
  that 
  the 
  commonwealth 
  of 
  Massa- 
  

   chusetts 
  has 
  curtailed 
  its 
  operations 
  against 
  the 
  gipsy 
  moth, 
  P 
  o 
  r 
  t 
  h 
  e- 
  

   tri'a 
  dispar 
  Linn. 
  There 
  was 
  every 
  reason 
  to 
  expect 
  the 
  ultimate 
  ex- 
  

   termination 
  of 
  this 
  pest 
  on 
  American 
  soil 
  if 
  the 
  work 
  was 
  continued. 
  This 
  

   insect 
  will 
  now 
  spread 
  over 
  our 
  country, 
  and 
  residents 
  of 
  New 
  York 
  state 
  

   may 
  soon 
  find 
  it 
  among 
  the 
  insect 
  pests 
  which 
  they 
  will 
  be 
  obliged 
  to 
  

   fight. 
  This 
  destructive 
  species 
  may 
  appear 
  within 
  our 
  state 
  at 
  any 
  time 
  ; 
  

   and 
  for 
  this 
  reason 
  a 
  brief 
  general 
  account 
  of 
  it 
  has 
  been 
  prepared, 
  that 
  

   our 
  people 
  may 
  be 
  forewarned. 
  Other 
  insects 
  of 
  interest 
  are 
  mentioned 
  

   under 
  " 
  Notes 
  for 
  the 
  year." 
  

  

  Office 
  work. 
  There 
  has 
  been 
  a 
  marked 
  increase 
  in 
  the 
  routine 
  office 
  

   work 
  since 
  last 
  year 
  in 
  spite 
  of 
  every 
  effort 
  to 
  save 
  time 
  along 
  this 
  line. 
  

   The 
  inspection 
  of 
  nurseries 
  under 
  the 
  direction 
  of 
  the 
  commissioner 
  of 
  

   agriculture 
  has 
  resulted 
  in 
  the 
  collection 
  of 
  many 
  scale 
  insects, 
  which 
  

   W2re 
  referred 
  to 
  this 
  office 
  for 
  name.
