﻿METEOROLOGICAL 
  CONDITIONS 
  AND 
  THE 
  CHINCH-BUG. 
  191 
  

  

  To 
  sum 
  up 
  tny 
  conclusions 
  from 
  the 
  data 
  herewith 
  presented 
  concerning 
  

   the 
  influence 
  of 
  meteorological 
  conditions 
  on 
  the 
  chinch-bug, 
  viewing 
  the 
  

   data 
  in 
  the 
  light 
  of 
  my 
  observations 
  on 
  the 
  occurrence 
  of 
  epidemic 
  diseases 
  

   among 
  the 
  bugs, 
  I 
  am 
  led 
  to 
  say 
  that 
  I 
  see 
  little 
  ground 
  for 
  any 
  confidence 
  

   in 
  the 
  effectiveness 
  of 
  wet 
  weather, 
  or 
  the 
  so-called 
  " 
  unfavorable 
  meteorolog- 
  

   ical 
  conditions," 
  as 
  a 
  direct 
  natural 
  check 
  on 
  or 
  a 
  preventive 
  of 
  chinch-bug 
  

   injury. 
  I 
  believe 
  that 
  much 
  of 
  the 
  destruction 
  of 
  chinch-bugs 
  assigned 
  by 
  

   observers 
  to 
  the 
  direct 
  effect 
  of 
  wet 
  weather 
  has 
  been 
  due 
  in 
  reality 
  to 
  the 
  

   ravages 
  of 
  one 
  or 
  more 
  of 
  the 
  deadly 
  contagious 
  diseases 
  of 
  the 
  chinch-bug, 
  

   which 
  are 
  doubtless 
  continuously 
  sporadically 
  present 
  in 
  the 
  extensive 
  chinch- 
  

   bug 
  region 
  of 
  North 
  America, 
  and 
  only 
  need 
  strongly 
  favoring 
  conditions, 
  

   such 
  as 
  an 
  abnormal 
  massing 
  of 
  bugs, 
  or 
  auspicious 
  meteorological 
  conditions, 
  

   or 
  an 
  artificial 
  assistance 
  in 
  dissemination, 
  or 
  all 
  of 
  these 
  or 
  some 
  of 
  them 
  

   combined, 
  to 
  become 
  epidemic 
  and 
  thus 
  widely 
  destructive. 
  There 
  is 
  no 
  

   spontaneous 
  generation 
  of 
  mysterious 
  germs 
  of 
  disease 
  by 
  wet 
  weather; 
  seeds 
  

   of 
  Sporotrichum 
  and 
  Empusa 
  are 
  produced 
  only 
  by 
  the 
  growth 
  and 
  matur- 
  

   ing 
  of 
  individuals 
  of 
  these 
  fungus 
  species, 
  and 
  while 
  such 
  growth 
  is 
  aided 
  by 
  

   favoring 
  meteorological 
  conditions, 
  the 
  seeds 
  or 
  spores 
  must 
  be 
  on 
  hand, 
  that 
  

   the 
  disease 
  may 
  begin 
  its 
  beneficent 
  destruction. 
  

  

  I 
  readily 
  admit, 
  of 
  course, 
  that 
  the 
  Kansas 
  record 
  of 
  meteorological 
  con- 
  

   ditions 
  in 
  their 
  influence 
  on 
  the 
  chinch-bug 
  is 
  a 
  short 
  one. 
  It 
  is 
  possible 
  

   that 
  the 
  observation 
  of 
  future 
  years 
  may 
  lead 
  me 
  to 
  discard 
  the 
  conclusions 
  

   based 
  upon 
  this 
  short 
  period 
  of 
  record. 
  I 
  am 
  inclined 
  to 
  believe, 
  however, 
  

   that 
  the 
  observations 
  of 
  a 
  longer 
  period 
  will 
  only 
  strengthen 
  these 
  conclu- 
  

   sions.
