﻿SCALE 
  INSECTS 
  OF 
  IMPORTANCE 
  3X1 
  

  

  This 
  insect 
  has 
  gained 
  a 
  secure 
  footing 
  in 
  New 
  York 
  state, 
  as 
  is 
  shown 
  

   by 
  its 
  having 
  been 
  found 
  at 
  one 
  time 
  or 
  another 
  in 
  29 
  of 
  the 
  61 
  counties. 
  

   The 
  known 
  infested 
  iocahties 
  are 
  Umited 
  in 
  many 
  cases 
  to 
  one 
  or 
  two 
  in 
  

   a 
  county. 
  There 
  has 
  been 
  no 
  thorough 
  survey 
  of 
  the 
  bearing 
  trees 
  of 
  

   the 
  state 
  ; 
  and, 
  when 
  that 
  is 
  made, 
  many 
  other 
  infested 
  orchards 
  may 
  be 
  

   discovered, 
  though 
  it 
  is 
  hoped 
  that 
  such 
  may 
  not 
  prove 
  to 
  be 
  the 
  case. 
  

   It 
  is 
  quite 
  important 
  for 
  the 
  owner 
  to 
  know 
  if 
  his 
  trees 
  be 
  infested 
  with 
  

   this 
  pest; 
  and 
  therefore 
  every 
  fruit-grower 
  is 
  urged 
  to 
  send 
  any 
  twigs 
  or 
  

   fruit, 
  which 
  present 
  a 
  suspicious 
  appearance, 
  to 
  an 
  entomologist 
  for 
  

   examination. 
  

  

  Original 
  home. 
  There 
  has 
  been 
  considerable 
  written 
  regarding 
  this- 
  

   matter 
  ; 
  and 
  it 
  now 
  looks 
  as 
  if 
  proof 
  would 
  shortly 
  be 
  forthcoming 
  to 
  

   show 
  that 
  this 
  species 
  is 
  a 
  native 
  of 
  Japan, 
  a 
  country 
  considered 
  by 
  sev- 
  

   eral 
  who 
  have 
  given 
  the 
  subject 
  attention, 
  to 
  be 
  most 
  probably 
  its 
  home. 
  

   The 
  evidence 
  brought 
  forward 
  up 
  to 
  August 
  1899 
  failed 
  to 
  convince 
  

   either 
  Dr 
  Howard 
  or 
  his 
  colaborer, 
  Dr 
  Marlatt, 
  that 
  the 
  pernicious 
  or 
  

   San 
  Jose 
  scale 
  is 
  a 
  native 
  of 
  Japan, 
  they 
  holding 
  that, 
  so 
  far 
  as 
  evidence 
  

   is 
  concerned, 
  there 
  was 
  nothing 
  to 
  prove 
  that 
  the 
  insect 
  did 
  not 
  come 
  to 
  

   us 
  from 
  China, 
  from 
  some 
  other 
  portion 
  of 
  eastern 
  Asia 
  or 
  possibly 
  from 
  

   some 
  of 
  the 
  islands 
  in 
  the 
  Pacific 
  or 
  from 
  Australia. 
  A 
  recent 
  note 
  by 
  

   Prof. 
  V. 
  L. 
  Kellogg 
  states 
  that 
  S. 
  I. 
  Kuwana, 
  assistant 
  in 
  entomology 
  at 
  

   Stanford 
  university, 
  spent 
  last 
  summer 
  in 
  a 
  systematic 
  investigation 
  of 
  

   Japanese 
  Coccidae 
  and 
  in 
  the 
  course 
  of 
  his 
  work 
  he 
  found 
  that 
  the 
  San 
  

   Jose 
  scale 
  was 
  distributed 
  over 
  the 
  whole 
  Japanese 
  empire, 
  it 
  being 
  in 
  

   certain 
  regions 
  a 
  serious 
  pest. 
  The 
  note 
  also 
  states 
  that 
  Mr 
  Kuwana 
  

   "finds 
  much 
  evidence 
  to 
  uphold 
  the 
  belief 
  that 
  the 
  insect 
  is 
  native 
  to 
  

   Japan." 
  This 
  announcement 
  does 
  not 
  settle 
  the 
  question, 
  but 
  it 
  looks 
  

   as 
  if 
  Japan 
  might 
  prove 
  to 
  be 
  the 
  original 
  home 
  of 
  the 
  pest.

  A

  of

  have 
  been

  The 
  latter 
  species 
  

   was 
  bred 
  in

  Prof. 
  Johnson 
  and 
  promises 
  to 
  become 
  

   an 
  important 
  aid 
  in 
  controlling 
  this 
  pest.
