﻿REPORT 
  OF 
  THE

  the 
  almost 
  total 
  destruction 
  of 
  the 
  bloom 
  in 
  the 
  acre 
  of 
  early 
  Moore 
  

   grapes 
  noticed 
  above. 
  It 
  is 
  possible 
  that 
  this 
  new 
  American 
  pest 
  

   is 
  an 
  introduced 
  species, 
  brought 
  to 
  the 
  Chautauqua 
  region 
  on 
  re- 
  

   cent 
  importations 
  of 
  grape. 
  It 
  is 
  to 
  be 
  hoped 
  that 
  it 
  will 
  not 
  mul- 
  

   tiply 
  greatly 
  and 
  become 
  a 
  serious 
  menace 
  to 
  this 
  important 
  

   industry. 
  

  

  Remedial 
  measures. 
  Nothing 
  very 
  definite 
  can 
  be 
  advised 
  in 
  

   the 
  way 
  of 
  control 
  measures. 
  Clean 
  culture, 
  supplemented 
  by 
  lib- 
  

   eral 
  feeding, 
  is 
  the 
  most 
  hopeful 
  method 
  of 
  avoiding 
  serious 
  in- 
  

   jury, 
  as 
  we 
  have 
  yet 
  to 
  find 
  this 
  insect 
  very 
  abundant 
  throughout 
  

   large, 
  well 
  cultivated 
  vineyards. 
  Most 
  of 
  the 
  infested 
  clusters 
  so 
  

   far 
  as 
  our 
  observation 
  goes, 
  occur 
  near 
  the 
  outside 
  of 
  a 
  vineyard 
  

   in 
  the 
  vicinity 
  of 
  abundant 
  natural 
  shelters. 
  The 
  burning 
  over 
  of 
  

   grassy 
  headlands 
  and 
  margins 
  of 
  ditches 
  in 
  early 
  spring 
  could 
  

   hardly 
  cause 
  much 
  injury 
  and 
  might 
  be 
  of 
  service 
  in 
  destroying 
  the 
  

   v/andering 
  maggots. 
  The 
  delicate 
  parent 
  insects 
  would 
  succumb 
  

   readily 
  to 
  pyrethrum 
  powder 
  and 
  presumably 
  would 
  be 
  stupefied 
  

   by 
  heavy 
  smoke. 
  These 
  insects 
  fly 
  mostly 
  during 
  the 
  quieter 
  part 
  

   of 
  the 
  day 
  and 
  it 
  might 
  be 
  practical, 
  in 
  the 
  case 
  of 
  a 
  badly 
  infested 
  

   vineyard, 
  to 
  watch 
  for 
  the 
  appearance 
  of 
  the 
  adults 
  and 
  then 
  

   stupefy 
  or 
  destroy 
  them 
  by 
  generating 
  a 
  heavy 
  smudge 
  throughout 
  

   the 
  vineyard. 
  Attempts 
  to 
  control 
  this 
  midge 
  by 
  applications 
  to 
  

   the 
  vines 
  before 
  the 
  flies 
  appear 
  are 
  very 
  likely 
  to 
  result 
  in 
  failure.

   The 
  abundant 
  occurrence 
  of 
  a 
  plant 
  louse 
  upon 
  gladioli 
  bulbs 
  is 
  

   something 
  unusual. 
  No 
  outbreak 
  of 
  the 
  kind 
  had 
  been 
  previously 
  

   brought 
  to 
  our 
  attention,

  he

  any 
  record 
  of 
  an 
  aphid 
  occurring 
  upon 
  

   this
