  Outdoor 
  plants: 
  Pumpkin, 
  squash, 
  cucumber, 
  roses, 
  violets, 
  box- 
  

   elder, 
  and 
  bean. 
  

  

  Greenhouse 
  plants: 
  Cucumber, 
  violets, 
  and 
  chrysanthemums. 
  

  

  Judging 
  from 
  the 
  data 
  gathered 
  in 
  the 
  foregoing 
  experiments 
  this 
  

   spray, 
  when 
  properly 
  used, 
  should 
  control 
  the 
  red 
  spider 
  on 
  all 
  plants 
  

   except 
  those 
  mentioned 
  in 
  the 
  following 
  paragraphs 
  : 
  

  

  Sweet 
  peas. 
  — 
  The 
  foliage 
  of 
  the 
  sweet 
  pea 
  is 
  very 
  hairy, 
  and 
  that 
  of 
  

   the 
  carnation 
  and 
  greenhouse 
  rose 
  is 
  so 
  smooth 
  that 
  the 
  flour 
  paste 
  

   will 
  not 
  stick 
  to 
  it 
  and 
  therefore 
  does 
  not 
  work 
  satisfactorily. 
  The 
  

   control 
  of 
  mites 
  upon 
  these 
  plants 
  is 
  taken 
  up 
  separately 
  in 
  succeeding 
  

   paragraphs. 
  The 
  finer 
  forms 
  of 
  sulphur 
  are 
  effective 
  upon 
  the 
  red 
  

   spider 
  attacking 
  sweet 
  pea 
  (see 
  p. 
  22) 
  provided 
  that 
  the 
  plants 
  are 
  

   growing 
  in 
  a 
  warm, 
  sunny 
  place. 
  The 
  sulphur 
  should 
  be 
  thoroughly 
  

   dusted 
  onto 
  the 
  infested 
  plants, 
  the 
  application 
  being 
  repeated 
  every 
  

   week 
  or 
  so. 
  

  

  Roses. 
  — 
  Most 
  roses 
  can 
  be 
  sprayed 
  with 
  flour 
  paste, 
  8-100, 
  but 
  the 
  

   leaves 
  of 
  roses 
  grown 
  in 
  greenhouses 
  are 
  so 
  smooth 
  and 
  glossy 
  that 
  

   the 
  paste 
  will 
  not 
  stick 
  to 
  them. 
  The 
  old 
  method 
  of 
  washing 
  them 
  

   with 
  the 
  garden 
  hose 
  remains 
  as 
  the 
  best 
  remedy 
  in 
  this 
  case. 
  

  

  Carnations. 
  — 
  A 
  weak 
  salt 
  or 
  soap 
  solution 
  is 
  used 
  by 
  some 
  growers 
  

   as 
  a 
  control 
  for 
  the 
  red 
  spider, 
  but 
  continual 
  spraying 
  with 
  water 
  is 
  

   the 
  universal 
  method 
  of 
  control. 
  

  

  Use 
  of 
  sulphur. 
  — 
  As 
  stated 
  on 
  page 
  22, 
  dry 
  sulphur 
  will 
  control 
  the 
  

   mites 
  upon 
  those 
  plants 
  which 
  expose 
  most 
  of 
  both 
  surfaces 
  of 
  their 
  

   leaves 
  to 
  the 
  sun 
  during 
  the 
  day, 
  but 
  the 
  flour-paste 
  spray 
  is 
  so 
  

   cheap, 
  available, 
  and 
  effective 
  that 
  where 
  large 
  areas 
  are 
  involved 
  it 
  

   is 
  recommended 
  in 
  preference 
  to 
  the 
  sulphur 
  treatment. 
  Sulphur, 
  

   however, 
  has 
  proved 
  more 
  or 
  less 
  effective 
  upon 
  the 
  squash, 
  pumpkin, 
  

   sweet 
  pea, 
  and 
  bean,

  BIBLIOGRAPHY. 
  

  

  There 
  have 
  been 
  few 
  publications 
  issued 
  upon 
  Tetranychus 
  bimacu- 
  

   latus 
  under 
  that 
  name, 
  but 
  it 
  has 
  been 
  recently 
  decided 
  by 
  Mr. 
  Nathan 
  

   Banks, 
  of 
  the 
  Bureau 
  of 
  Entomology, 
  that 
  the 
  cotton 
  red 
  spider 
  

   ( 
  Tetranychus 
  gloveri 
  Banks) 
  is 
  synonymous 
  with 
  Tetranychus 
  bimacu- 
  

   latus 
  Harvey, 
  and 
  references 
  to 
  this 
  name 
  are 
  included 
  in 
  the 
  following 
  

   list. 
  It 
  is 
  also 
  more 
  than 
  probable 
  that 
  many 
  of 
  the 
  mites 
  referred 
  

   to 
  by 
  American 
  writers 
  under 
  the 
  name 
  of 
  Tetranychus 
  telarius 
  are 
  

   really 
  T. 
  bimaculatus, 
  so 
  that 
  the 
  more 
  important 
  references 
  to 
  that 
  

   species 
  are 
  included 
  below.
