  or

  Cneorrhinus 
  plagiatus 
  (geminatus), 
  known 
  as 
  a 
  pest 
  of 
  vines 
  since 
  

   1839, 
  causes 
  considerable 
  damage 
  by 
  attacking 
  the 
  young 
  buds, 
  and 
  

   is 
  especially 
  abundant 
  on 
  sandy 
  soils. 
  The 
  best 
  means 
  of 
  capturing 
  

   the 
  weevils 
  is 
  to 
  use 
  a 
  Haltica 
  funnel 
  into 
  which 
  the 
  vine-stocks 
  are 
  

   vigorously 
  shaken. 
  

  

  The 
  Locustid, 
  Ephippiger 
  biterrensis, 
  is 
  found 
  all 
  over 
  the 
  vine- 
  

   growing 
  districts 
  of 
  France 
  and 
  is 
  exceedingly 
  voracious 
  ; 
  it 
  will 
  eat 
  

   all 
  kinds 
  of 
  plants 
  and 
  at 
  times 
  other 
  insects. 
  It 
  frequently 
  bites 
  

   the 
  labourers 
  sleeping 
  in 
  the 
  vineyards. 
  Perhaps 
  the 
  best 
  means 
  of 
  

   controlHng 
  these 
  pests 
  is 
  by 
  killing 
  the 
  perfect 
  insects 
  with 
  wooden 
  

   racquets 
  as 
  they 
  fly 
  off 
  the 
  plants. 
  The 
  Capsid 
  bug, 
  Lopus 
  sulcatuSy 
  

   is 
  very 
  common 
  in 
  vineyards 
  in 
  the 
  Department 
  of 
  the 
  Yonne 
  and 
  

   the 
  Cher.

  Pulvinaria 
  vitis 
  is 
  often 
  very 
  numerous 
  on 
  vines. 
  As 
  remedies, 
  the 
  

   removal 
  of 
  all 
  old 
  bark 
  during 
  the 
  winter 
  and 
  painting 
  the 
  stocks 
  Tvath 
  

   a 
  50 
  per 
  cent, 
  solution 
  of 
  sulphate 
  of 
  iron 
  or 
  a 
  4 
  per 
  cent, 
  solution 
  of 
  

   sulphuric 
  acid 
  in 
  June, 
  before 
  the 
  insects 
  have 
  acquired 
  their 
  shield, 
  

   are 
  recommended. 
  The 
  same 
  remedies 
  are 
  applicable 
  to 
  Eulecanium 
  

   (Lecanium) 
  persicae 
  and 
  Pseudococcus 
  {Dactylopius) 
  vitis, 
  which 
  are 
  

   also 
  capable 
  of 
  doing 
  considerable 
  damage. 
  The 
  latter 
  scale-insect 
  

   is 
  generally 
  to 
  be 
  feared 
  because 
  it 
  is 
  the 
  precursor 
  of 
  the 
  fungus 
  

   disease 
  known 
  as 
  fumagine, 
  which 
  commonly 
  develops 
  upon 
  the 
  

   waxy 
  substances 
  secreted 
  upon 
  white 
  scale. 
  The 
  grey 
  scale, 
  Targionia 
  

   (Aspidiotus) 
  vitis, 
  is 
  very 
  common 
  in 
  the 
  warmer 
  districts, 
  Nice, 
  

   Algiers, 
  Italy, 
  etc., 
  but 
  is 
  never 
  very 
  destructive. 
  It 
  has 
  a 
  formidable 
  

   enemy 
  in 
  a 
  small 
  Hymenopteron, 
  Spilomena 
  (Celia) 
  troglodytes, 
  the 
  

   female 
  of 
  which 
  stores 
  her 
  nest 
  with 
  these 
  scales. 
  

  

  Several 
  pages 
  of 
  the 
  book 
  are 
  devoted 
  to 
  Phylloxera 
  vastatrix, 
  and 
  

   though 
  an 
  enormous 
  number 
  of 
  remedies 
  have 
  been 
  proposed 
  against 
  

   this 
  pest, 
  no 
  really 
  satisfactory 
  one 
  exists, 
  excepting 
  the 
  use 
  of 
  American 
  

   vine-stocks. 
  Dasyneura 
  (Cecidomyia) 
  oenophila 
  produces 
  galls 
  on 
  the 
  

   underside 
  of 
  the 
  vine 
  leaves, 
  but 
  seldom 
  does 
  serious 
  damage. 
  To 
  

   those 
  who 
  are 
  interested 
  in 
  vine 
  pests, 
  their 
  life-history 
  and 
  the 
  

   methods 
  by 
  which 
  they 
  may 
  be 
  combated, 
  this 
  book 
  will 
  constitute 
  a 
  

   mine 
  of 
  information 
  and 
  should 
  be 
  consulted 
  in 
  the 
  original.
