  The 
  beetroot 
  Aphis 
  is 
  also 
  widespread 
  iu 
  France 
  and 
  was 
  the 
  cause 
  of 
  

   considerable 
  damage 
  in 
  Herault 
  in 
  1913. 
  

  

  The 
  Halticid 
  beetle, 
  Chaetocnema 
  tibialis, 
  lives 
  not 
  only' 
  on 
  the 
  

   cultivated 
  beetroot, 
  but 
  on 
  all 
  plants 
  belonging 
  to 
  the 
  Salsolaceae. 
  

   It 
  has 
  several 
  generations 
  and 
  the 
  larva 
  bores 
  galleries 
  in 
  the 
  paren- 
  

   chyma 
  of 
  the 
  stem 
  and 
  leaves. 
  There 
  is 
  some 
  fear 
  of 
  its 
  spreading 
  

   northwards 
  up 
  the 
  Rhone 
  valley. 
  

  

  Conor 
  rhynchus 
  mendicus 
  is 
  the 
  most 
  harmful 
  insect 
  attacking 
  beetroot 
  

   in 
  the 
  south. 
  It 
  is 
  a 
  large 
  weevil, 
  appearing 
  in 
  the 
  spring, 
  and 
  devours 
  

   the 
  young 
  leaves. 
  The 
  eggs 
  are 
  laid 
  on 
  the 
  ground 
  ; 
  the 
  larvae 
  bore 
  

   into 
  the 
  plants, 
  particularly 
  into 
  the 
  root. 
  There 
  is 
  one 
  generation 
  

   a 
  year 
  ; 
  the 
  period 
  of 
  development 
  varies 
  in 
  length 
  ; 
  usually 
  the 
  larva 
  

   undergoes 
  metamorphosis 
  in 
  the 
  earth 
  or 
  in 
  the 
  tissues 
  of 
  the 
  beetroot 
  ; 
  

   the 
  adult 
  appears 
  in 
  the 
  autumn, 
  but 
  hides 
  in 
  the 
  earth 
  until 
  the 
  follow- 
  

   ing 
  spring 
  ; 
  in 
  some 
  cases 
  the 
  hfe-cycle 
  is 
  more 
  rapid 
  and 
  adults 
  

   may 
  appear 
  in 
  September, 
  in 
  which 
  case 
  they 
  feed, 
  but 
  do 
  not 
  re- 
  

   produce 
  until 
  the 
  following 
  spring. 
  Development 
  will 
  continue 
  in 
  

   roots 
  that 
  have 
  been 
  stored. 
  Attempts 
  to 
  control 
  the 
  larvae 
  have 
  

   failed 
  ; 
  spraying 
  the 
  foUage 
  with 
  arsenicals 
  is 
  said 
  to 
  have 
  good 
  results 
  

   against 
  the 
  adults, 
  but 
  the 
  author, 
  after 
  having 
  tried 
  this 
  with 
  con- 
  

   siderable 
  care 
  for 
  two 
  or 
  three 
  years, 
  does 
  not 
  recommend 
  it. 
  Natural 
  

   enemies 
  of 
  C. 
  mendicus 
  appear 
  to 
  be 
  numerous, 
  especially 
  Bacillus 
  

   cleoni, 
  which 
  resembles 
  B. 
  coli, 
  but 
  differs 
  in 
  its 
  power 
  to 
  liquefy 
  

   gelatin. 
  

  

  The 
  wee\'il. 
  Lixus 
  scabricollis, 
  is 
  for 
  the 
  first 
  time 
  recorded 
  as 
  injurious 
  

   to 
  beetroots 
  in 
  Montpellier 
  ; 
  the 
  larvae 
  hve 
  in 
  the 
  main 
  stem, 
  and 
  the 
  

   adults 
  on 
  the 
  leaves. 
  The 
  damage 
  is 
  at 
  present 
  shght, 
  but 
  in 
  a 
  

   favourable 
  season 
  might 
  be 
  much 
  more 
  serious, 
  as 
  has 
  been 
  the 
  case 
  with 
  

   L. 
  elongatus 
  var. 
  rufitarsis 
  in 
  Tunis.

  A 
  short 
  account 
  of 
  the 
  vine 
  moth 
  and 
  of 
  the 
  methods 
  of 
  controlling 
  

   it 
  m 
  the 
  valleys 
  of 
  the 
  Rhine 
  and 
  Moselle, 
  is 
  given. 
  Good 
  results 
  were 
  

   obtained 
  with 
  the 
  mixture 
  made 
  by 
  the 
  firm 
  of 
  Golaz 
  in 
  Klisnacht, 
  and 
  

   also 
  with 
  nicotin 
  sprays. 
  The 
  cost 
  of 
  either 
  of 
  these 
  is 
  from 
  50 
  to 
  65 
  

   shillings 
  per 
  acre.

  up 
  the 
  grapes

  paper 
  bags

  the 
  

   time 
  when 
  egg-lapng 
  takes 
  place, 
  was 
  found 
  to 
  give 
  good 
  results 
  ; 
  

   15,000 
  bunches 
  were 
  covered 
  in 
  this 
  way, 
  at 
  a 
  cost 
  of 
  about 
  5?. 
  and 
  

   the 
  damage 
  done 
  by 
  the 
  pest 
  in 
  these 
  circumstances 
  was 
  negligible.
