  CONTAGIOUS 
  DISEASES 
  OF 
  THE 
  CHINCH-BUG. 
  

  

  Wm. 
  Weeks, 
  Idana, 
  Clay 
  county. 
  Experimented 
  in 
  the 
  corn 
  field. 
  Box 
  received 
  

   from 
  the 
  station 
  contained 
  white-fungus 
  bugs. 
  When 
  infected 
  bugs 
  were 
  first 
  dis- 
  

   tributed 
  among 
  healthy 
  bugs 
  the 
  weather 
  was 
  wet. 
  Many 
  of 
  the 
  old 
  bugs 
  died 
  and 
  

   became 
  white. 
  The 
  weather 
  became 
  hot 
  and 
  dry, 
  and 
  while 
  the 
  bugs, 
  old 
  and 
  young, 
  

   continued 
  to 
  die, 
  they 
  did 
  not 
  turn 
  white. 
  From 
  5 
  to 
  10 
  large 
  blue 
  flies 
  were 
  found 
  

   dead 
  in 
  the 
  sheath 
  of 
  the 
  corn 
  blades 
  on 
  each 
  corn 
  hill 
  where 
  the 
  bugs 
  had 
  died. 
  These 
  

   flies 
  were 
  not 
  fungus 
  covered. 
  At 
  the 
  time 
  of 
  my 
  visit 
  not 
  many 
  live 
  chinch-bugs 
  

   remained. 
  

  

  Benjamin 
  Way, 
  Clay 
  Center, 
  Clay 
  county. 
  Two 
  days 
  after 
  putting 
  infection 
  in 
  his 
  

   wheat 
  field, 
  it 
  rained 
  very 
  hard. 
  Six 
  or 
  eight 
  days 
  later, 
  not 
  a 
  live 
  bug 
  was 
  anywhere 
  

   to 
  be 
  found, 
  where 
  bugs 
  had 
  previously 
  been 
  in 
  great 
  numbers. 
  Searching 
  around 
  

   and 
  beneath 
  clods, 
  Mr. 
  Way 
  says 
  that 
  he 
  found 
  dead 
  white-fungus 
  covered 
  bugs 
  in 
  

   heaps, 
  perhaps 
  a 
  teaspoonful 
  in 
  a 
  place.

  The 
  first 
  15 
  rows 
  of 
  corn 
  in 
  Mr. 
  On- 
  

   stadt's 
  field 
  were 
  black 
  with 
  bugs. 
  On 
  the 
  fourth 
  day 
  after 
  infected 
  bugs 
  had 
  been 
  

   placed 
  in 
  the 
  corn 
  hills, 
  the 
  live 
  bugs 
  became 
  uneasy. 
  " 
  They 
  got 
  down 
  off 
  the 
  

   stalks 
  and 
  never 
  got 
  back." 
  Dead 
  white-fungus 
  bugs 
  were 
  found 
  scattered 
  around 
  

   on 
  the 
  ground, 
  and 
  8 
  or 
  10 
  moulded 
  bugs 
  were 
  seen 
  together. 
  A 
  few 
  dead 
  flies 
  were 
  

   found 
  between 
  the 
  blade 
  and 
  corn 
  stalk, 
  and 
  sometimes 
  at 
  the 
  foot 
  of 
  the 
  stalk. 
  

   The 
  ravages 
  to 
  the 
  growing 
  crops 
  were 
  entirely 
  stopped. 
  During 
  the. 
  time 
  of 
  the 
  

   trial 
  there 
  was 
  an 
  occasional 
  shower.

  Concordia, 
  Cloud 
  county. 
  The 
  infected 
  bugs 
  were 
  used 
  in 
  corn. 
  

   On 
  the 
  eighth 
  day 
  after 
  putting 
  out 
  infected 
  bugs 
  no 
  live 
  bugs 
  were 
  working 
  on 
  

   the 
  corn, 
  and 
  many 
  dead 
  white-fungus 
  covered 
  bugs 
  were 
  found 
  on 
  the 
  ground 
  and 
  

   under 
  clods. 
  Some 
  bunches 
  of 
  dead 
  bugs 
  were 
  found, 
  but 
  no 
  white 
  fungus 
  was 
  

   seen 
  among 
  them. 
  Shells 
  of 
  bugs 
  were 
  scattered 
  on 
  the 
  ground, 
  but 
  these 
  were 
  few 
  

   in 
  number 
  and 
  were 
  not 
  in 
  heaps. 
  

  

  Thos. 
  Day, 
  Concordia, 
  Cloud 
  county. 
  Mr. 
  Day 
  reports 
  that 
  bugs 
  were 
  very 
  nu- 
  

   merous 
  in 
  his 
  corn 
  field, 
  but 
  that 
  in 
  four 
  or 
  five 
  days 
  after 
  he 
  planted 
  the 
  infection 
  

   the 
  bugs 
  got 
  sick, 
  and 
  left 
  the 
  corn 
  stalks 
  for 
  the 
  ground. 
  There 
  were 
  bunches 
  of 
  

   shells, 
  with 
  dead 
  bugs 
  at 
  the 
  bottom 
  of 
  the 
  heaps, 
  found 
  on 
  the 
  ground. 
  A 
  few 
  dead 
  

   fungus-covered 
  bugs 
  were 
  found. 
  Many 
  shells 
  of 
  bugs 
  were 
  found 
  in 
  Mr. 
  Day's 
  mil- 
  

   let 
  field 
  where 
  infection 
  had 
  been 
  used. 
  In 
  the 
  millet 
  field, 
  at 
  the 
  time 
  of 
  my 
  visit, 
  I 
  

   found 
  a 
  great 
  number 
  of 
  live 
  bugs 
  near 
  the 
  heaps 
  of 
  shells, 
  but 
  in 
  the 
  corn 
  field 
  ad- 
  

   joining 
  the 
  millet 
  a 
  live 
  bug 
  was 
  seldom 
  found. 
  In 
  a 
  neighboring 
  field, 
  one-fourth 
  of 
  

   a 
  mile 
  distant 
  and 
  into 
  which 
  infection 
  is 
  not 
  known 
  to 
  have 
  been 
  carried, 
  heaps 
  of 
  

   shells, 
  with 
  dead 
  bugs 
  at 
  the 
  bottom, 
  were 
  seen. 
  

  

  Hon. 
  S. 
  C. 
  Wheelee, 
  Concordia, 
  Cloud 
  county. 
  Received 
  a 
  box 
  containing 
  in- 
  

   fected 
  bugs 
  from 
  the 
  Experiment 
  Station, 
  but 
  paid 
  no 
  very 
  close 
  attention 
  to 
  the 
  

   experiment. 
  The 
  trial 
  was 
  made 
  in 
  a 
  patch 
  of 
  sorghum, 
  around 
  the 
  edges 
  of 
  which 
  

   the 
  blades 
  had 
  begun 
  to 
  turn 
  yellow 
  and 
  die. 
  The 
  first 
  dead 
  bugs 
  found 
  were 
  covered 
  

   with 
  white 
  fungus, 
  and 
  were 
  not 
  discovered 
  until 
  a 
  great 
  many 
  had 
  died. 
  Empusa- 
  

   covered 
  bugs 
  were 
  also 
  found, 
  but 
  not 
  in 
  numbers 
  as 
  great 
  as 
  white-fungus 
  bugs. 
  

   Also 
  bunches 
  of 
  shells, 
  with 
  an 
  occasional 
  dead 
  bug 
  among 
  the 
  skins, 
  were 
  found 
  — 
  

   one-half 
  pint 
  in 
  a 
  heap. 
  The 
  ravages 
  of 
  the 
  pest 
  were 
  stopped. 
  In 
  uninfected 
  fields 
  

   near 
  the 
  above, 
  no 
  dead 
  bugs 
  nor 
  skins 
  were 
  seen 
  or 
  even 
  reported, 
  although 
  a 
  care- 
  

   ful 
  search 
  was 
  made. 
  Several 
  neighbors 
  who 
  had 
  come 
  to 
  Mr. 
  Wheeler's 
  field 
  and 
  had 
  

   gotten 
  dead 
  bugs 
  reported 
  that 
  the 
  contagion 
  had 
  been 
  communicated 
  in 
  their 
  fields-

  Nelson, 
  Concordia, 
  Cloud 
  county. 
  Mr. 
  Nelson 
  went 
  to 
  Mr. 
  Wheeler's 
  field 
  

   and 
  got 
  one 
  bunch 
  of 
  skins 
  and 
  dead 
  bugs. 
  He 
  scattered 
  these 
  skins 
  and 
  bugs 
  

   among 
  the 
  bugs, 
  which 
  had 
  collected 
  in 
  such 
  numbers 
  on 
  his 
  corn 
  that 
  the 
  stalks
