  This 
  pest 
  is 
  easily 
  seen 
  on 
  the 
  underside 
  of 
  the 
  leaves 
  on 
  account 
  of 
  

   its 
  white 
  woolly 
  secretions. 
  The 
  larvae 
  hatch 
  in 
  July 
  and 
  after 
  Uving 
  

   on 
  the 
  leaves, 
  migrate 
  to 
  the 
  old 
  bark, 
  cracks 
  in 
  the 
  vine-stakes, 
  etc., 
  

   in 
  search 
  of 
  a 
  winter 
  refuge, 
  where 
  they 
  spin 
  a 
  thick, 
  white 
  web. 
  

   Early 
  in 
  spring 
  the 
  female 
  attacks 
  the 
  young 
  vine-shoots, 
  and 
  when 
  

   mature, 
  migrates 
  to 
  the 
  leaves 
  to 
  oviposit. 
  In 
  the 
  Palatinate 
  this 
  pest 
  

   of 
  French 
  vineyards 
  has 
  not 
  yet 
  done 
  much 
  harm, 
  but 
  control 
  measures 
  

   ought 
  to 
  be 
  at 
  once 
  adopted. 
  Spraying 
  with 
  nicotin 
  on 
  the 
  underside 
  

   of 
  the 
  leaves 
  should 
  be 
  carried 
  out 
  in 
  summer, 
  while 
  in 
  winter 
  the 
  

   stocks 
  should 
  be 
  scrubbed. 
  The 
  vines 
  should 
  be 
  trained 
  on 
  wires.

  provides 
  additional 
  evidence 
  that 
  the 
  Narcissus 
  fly 
  

   enters 
  its 
  host 
  at 
  the 
  neck 
  of 
  the 
  bulb 
  and 
  that 
  there 
  are 
  at 
  least 
  two 
  

   broods 
  of 
  flies 
  in 
  the 
  year 
  ; 
  larvae 
  which 
  had 
  been 
  submerged 
  in 
  water 
  

   for 
  72 
  hours 
  were 
  observed 
  to 
  hatch 
  out 
  successfully. 
  One 
  observer 
  

   states 
  that 
  in 
  partially 
  infested 
  bulbs 
  E. 
  strigatus 
  feeds 
  only 
  on 
  the 
  

   rotting 
  portions 
  and 
  may 
  therefore 
  prove 
  to 
  be 
  more 
  beneficial 
  than 
  

   harmful.

  Since 
  1903 
  the 
  vine-growing 
  village 
  of 
  Rhodt 
  has 
  had 
  a 
  75-acre 
  plot 
  

   on 
  which 
  experiments 
  are 
  made 
  in 
  capturing 
  the 
  vine-moth 
  with 
  sticky 
  

   racquets, 
  carried 
  out 
  by 
  school 
  children. 
  The 
  period 
  of 
  operations 
  

   lasts 
  from 
  8 
  to 
  14 
  days, 
  according 
  to 
  weather 
  conditions. 
  Each 
  child 
  

   is 
  paid 
  about 
  2JcZ. 
  per 
  evening 
  and 
  prizes 
  are 
  distributed 
  to 
  the 
  most 
  

   successful. 
  This 
  year 
  some 
  100,000 
  moths, 
  mostly 
  Clysia 
  ambiguella, 
  

   were 
  taken 
  on 
  97 
  racquets 
  in 
  10 
  days. 
  As 
  a 
  measure 
  complementary 
  to 
  

   winter 
  treatment, 
  this 
  system 
  is 
  to 
  be 
  strongly 
  recommended.

  Some 
  success 
  is 
  said 
  to 
  have 
  been 
  achieved 
  in 
  the 
  control 
  of 
  Phyl- 
  

   loxera 
  in 
  Bavaria. 
  Between 
  1895 
  and 
  1911 
  about 
  225 
  acres 
  of 
  vine- 
  

   yards 
  were 
  examined, 
  stock 
  by 
  stock, 
  in 
  two 
  infested 
  locahties. 
  From 
  

   1874 
  to 
  1911 
  the 
  cost 
  of 
  examination 
  and 
  control 
  amounted 
  to 
  about 
  

   £114,000 
  and 
  about 
  200 
  acres 
  were 
  found 
  to 
  be 
  infested. 
  The 
  vine- 
  

   yards 
  of 
  Bavaria 
  cover 
  about 
  55,000 
  acres 
  and 
  the 
  wine 
  produced 
  is 
  

   worth 
  about 
  £1,250,000 
  per 
  annum.
