  would 
  naturally 
  tend 
  to 
  the 
  multiplication 
  of 
  the 
  hop 
  aphis, 
  as 
  was 
  so 
  

   markedly 
  illustrated 
  in 
  1886. 
  

  

  " 
  The 
  hop 
  growers 
  have 
  therefore 
  been 
  advised 
  to 
  keep 
  close 
  watch 
  

   for 
  the 
  first 
  appearance 
  of 
  the 
  hop 
  aphis 
  on 
  the 
  upper 
  leaves 
  of 
  the 
  

   outer 
  rows 
  of 
  their 
  hop 
  yards. 
  They 
  will 
  probably 
  be 
  seen 
  there 
  about 
  

   the 
  last 
  of 
  May 
  or 
  the 
  first 
  of 
  June 
  as 
  full-grown, 
  winged 
  females, 
  

   which 
  have 
  just 
  flown 
  from 
  neighboring 
  plum 
  trees, 
  where 
  the 
  winter 
  

   had 
  been 
  passed 
  in 
  the 
  egg 
  and 
  the 
  early 
  spring 
  as 
  wingless 
  females. 
  

  

  " 
  If 
  these, 
  the 
  mothers 
  and 
  progenitors 
  of 
  a 
  number 
  of 
  successive 
  

   broods 
  through 
  the 
  summer, 
  are 
  killed 
  at 
  this 
  time 
  by 
  proper 
  spraying 
  

   with 
  suitable 
  insecticides 
  — 
  in 
  the 
  proportion 
  that 
  they 
  are 
  destroyed 
  

   will 
  subsequent 
  injury 
  to 
  the 
  crop 
  be 
  prevented. 
  

  

  " 
  It 
  is 
  said 
  that 
  in 
  England 
  the 
  hop 
  growers 
  do 
  not 
  attempt 
  to 
  grow 
  

   a 
  hop 
  crop 
  without 
  their 
  regular 
  'hop 
  washings,' 
  which 
  we 
  call 
  

   spraying." 
  

  

  Keports 
  of 
  unusual 
  abundance 
  of 
  aphides 
  on 
  fruit 
  trees 
  came 
  

   from 
  the 
  following 
  counties, 
  indicating 
  that 
  they 
  were 
  not 
  con- 
  

   fined 
  to 
  any 
  particular 
  part 
  of 
  the 
  State 
  : 
  Westchester 
  (on 
  apple 
  

   and 
  cherry 
  in 
  June), 
  Dutchess, 
  Schoharie 
  (buds 
  literally 
  covered 
  

   in 
  June), 
  Schenectady, 
  Chenango 
  (on 
  apples 
  and 
  pears 
  in 
  May), 
  

   Oneida 
  and 
  Onondaga 
  in 
  May, 
  Madison, 
  Oswego 
  and 
  Chautauqua. 
  

  

  Of 
  the 
  hop 
  vine 
  aphis, 
  Phorodon 
  humuli, 
  the 
  most 
  severe 
  injury 
  

   seems 
  to 
  have 
  been 
  caused 
  in 
  the 
  southern 
  part 
  of 
  Dutchess 
  

   county, 
  where 
  hop 
  yards 
  were 
  entirely 
  stripped, 
  save 
  here 
  and 
  

   there 
  a 
  blackened, 
  perforated 
  leaf 
  of 
  a 
  new 
  shoot. 
  Nothing 
  was 
  

   done 
  to 
  stop 
  the 
  ravages 
  of 
  the 
  insect 
  ; 
  so 
  quickly 
  did 
  it 
  do 
  its 
  

   work 
  that 
  it 
  was 
  almost 
  done 
  before 
  it 
  was 
  discovered. 
  The 
  

   crop 
  is 
  an 
  entire 
  failure 
  (New 
  York 
  State 
  Weather 
  Crop 
  Bulletin, 
  

   July 
  8th, 
  1893). 
  In 
  Madison 
  county- 
  the 
  destruction 
  of 
  the 
  

   crop 
  was 
  threatened 
  in 
  early 
  July, 
  but 
  a 
  more 
  favorable 
  condi- 
  

   tion 
  was 
  reported 
  later. 
  Spraying 
  was 
  resorted 
  to 
  in 
  several 
  of 
  

   the 
  counties 
  — 
  in 
  Franklin 
  and 
  others 
  — 
  with 
  gratifying 
  results.

  It 
  has 
  been 
  a 
  remarkable 
  year 
  for 
  grasshoppers.

  abun- 
  

   dance 
  in

  part 
  of 
  the

  where 
  dry 
  weather 
  has 
  

   prevailed 
  to 
  the 
  extent 
  of 
  severe 
  drouth, 
  has 
  made 
  them 
  a

   table 
  plague. 
  ' 
  It 
  is 
  very 
  unusual

   About 
  the

  of 
  July

  were 
  reported 
  as 
  numerous 
  in
