﻿REPORT 
  OF 
  THE 
  STATE 
  ENTOMOLOGIST

  Poisoned 
  Iran 
  mash. 
  — 
  This 
  was 
  used 
  in 
  different 
  localities 
  in 
  the 
  State 
  

   the 
  present 
  year 
  with 
  considerable 
  success 
  in 
  infested 
  fields. 
  It 
  was 
  re- 
  

   ported 
  in 
  several 
  instances 
  that 
  the 
  caterpillars 
  would 
  even 
  leave 
  tlie 
  

   corn 
  upon 
  which 
  they 
  were 
  feeding 
  and 
  descend 
  to 
  the 
  ground 
  for 
  the 
  

   purpose 
  of 
  eating 
  the 
  attractive 
  bait. 
  Large 
  numbers 
  were 
  killed 
  by 
  its 
  

   use 
  and 
  the 
  crops 
  were 
  protected 
  to 
  a 
  considerable 
  extent. 
  The 
  recipe 
  

   for 
  its 
  preparation 
  is 
  as 
  follows: 
  35 
  lbs. 
  wheat 
  bran, 
  i 
  gallon 
  of 
  molasses 
  

   and 
  I 
  lb. 
  Paris 
  green 
  mixed 
  to 
  a 
  proper 
  consistency 
  with 
  hot 
  water. 
  It 
  

   should 
  be 
  distributed 
  just 
  before 
  nightfall, 
  as 
  then 
  the 
  caterpillars 
  are 
  

   usually 
  beginning 
  their 
  feeding. 
  

  

  Ditching. 
  — 
  This 
  method 
  is 
  of 
  value 
  only 
  in 
  keeping 
  the 
  army-worms 
  

   out 
  of 
  fields 
  comparatively 
  free 
  from 
  them, 
  and 
  it 
  is 
  quite 
  effective 
  if 
  

   properly 
  conducted. 
  The 
  ditch 
  may 
  be 
  made 
  by 
  plowing 
  a 
  rather 
  deep 
  

   furrow 
  with 
  its 
  perpendicular 
  side 
  towards 
  the 
  field 
  to 
  be 
  protected. 
  At 
  

   intervals 
  in 
  the 
  ditch 
  of 
  fifteen 
  or 
  twenty 
  feet, 
  holes 
  of 
  about 
  two 
  feet 
  in 
  

   depth 
  should 
  be 
  made 
  (easily 
  done 
  with 
  a 
  post-hole 
  auger) 
  into 
  which 
  

   the 
  caterpillars, 
  unable 
  to 
  climb 
  the 
  wall, 
  will 
  fall 
  and 
  die. 
  As 
  often 
  as 
  

   the 
  holes 
  become 
  filled 
  they 
  may 
  be 
  easily 
  killed 
  and 
  removed. 
  The 
  

   furrow 
  or 
  ditch 
  should 
  have 
  the 
  perpendicular 
  side 
  clear 
  of 
  all 
  weeds, 
  

   roots, 
  and 
  other 
  matter 
  that 
  might 
  aid 
  in 
  climbing 
  out. 
  An 
  improve- 
  

   ment 
  on 
  the 
  single 
  furrow 
  has 
  been 
  recommended 
  by 
  a 
  resident 
  of 
  

   Dutchess 
  county. 
  The 
  first 
  furrow 
  is 
  turned 
  towards 
  the 
  crop 
  to 
  be 
  

   protected, 
  and 
  then 
  returning 
  with 
  the 
  plow 
  in 
  the 
  furrow, 
  the 
  perpendic- 
  

   ular 
  wall 
  is 
  made 
  next 
  to 
  the 
  crop. 
  By 
  this 
  means 
  soft 
  crumbly 
  earth 
  is 
  

   obtained 
  on 
  both 
  sides 
  of 
  the 
  furrow, 
  which 
  will 
  be 
  more 
  difficult 
  for 
  a 
  

   caterpillar 
  to 
  climb 
  than 
  a 
  smooth 
  firm 
  surface. 
  If 
  the 
  one 
  ditch 
  should 
  

   by 
  any 
  means 
  prove 
  insufficient, 
  a 
  second, 
  a 
  short 
  distance 
  in 
  advance 
  of 
  

   the 
  other, 
  could 
  be 
  made. 
  

  

  Bands 
  of 
  ta?-. 
  — 
  Broad 
  bands 
  of 
  tar 
  have 
  been 
  used 
  in 
  some 
  of 
  the 
  

   Western 
  states 
  in 
  lieu 
  of 
  ditches, 
  but, 
  as 
  they 
  require 
  to 
  be 
  renewed 
  as 
  

   often 
  as 
  they 
  become 
  biidged 
  or 
  the 
  tar 
  hardened, 
  this 
  method 
  would 
  

   doubtless 
  be 
  more 
  expensive 
  than 
  the 
  ditching. 
  Another 
  method 
  is 
  the 
  

   tarrii.g 
  of 
  boards 
  and 
  setting 
  them 
  up 
  on 
  edge 
  as 
  barriers. 
  This 
  is 
  more 
  

   effectual 
  than 
  bands 
  of 
  tar, 
  but 
  it 
  is 
  more 
  expensive. 
  

  

  Poisoned 
  strips. 
  — 
  A 
  field 
  may 
  often 
  be 
  protected 
  by 
  spraying 
  an 
  ex- 
  

   posed 
  strip 
  heavily 
  with 
  Paris 
  green 
  and 
  water, 
  or 
  by 
  sprinkling 
  it 
  with 
  

   land 
  plaster 
  and 
  Paris 
  green. 
  In 
  either 
  case 
  it 
  should 
  be 
  heavily 
  poisoned. 
  

   The 
  poisoned 
  portion 
  of 
  the 
  crop 
  should 
  be 
  carefully 
  destroyed 
  after 
  it 
  

   ha*^ 
  served 
  its 
  purpose, 
  in 
  order 
  to 
  prevent 
  the 
  chance 
  of 
  its 
  being 
  eaten 
  

   by 
  stock.
