  Calandra 
  oryzae. 
  Larvae 
  and 
  pupae 
  of 
  Cossus 
  cossus 
  were 
  taken 
  

   from 
  old 
  larch 
  stools, 
  in 
  which 
  no 
  larval 
  borings 
  could 
  be 
  found, 
  but 
  

   further 
  examination 
  revealed 
  these 
  in 
  neighbouring 
  broad-leaved 
  trees, 
  

   which 
  had 
  been 
  left 
  by 
  the 
  mature 
  larvae 
  for 
  pupation. 
  The 
  larvae 
  

   of 
  Hepialus 
  humuli 
  are 
  recorded 
  as 
  damaging 
  oats, 
  potatoes, 
  artichokes, 
  

   carrots, 
  asparagus 
  and 
  hops. 
  In 
  January, 
  specimens 
  were 
  received 
  

   which 
  were 
  reported 
  to 
  be 
  destroying 
  a 
  plantation 
  of 
  two-yeard-old 
  

   ash, 
  eating 
  the 
  plants 
  off 
  at 
  or 
  just 
  below 
  the 
  surface 
  of 
  the 
  ground. 
  

   Vaporite 
  incorporated 
  with 
  the 
  soil 
  does 
  some 
  good, 
  also 
  trapping 
  

   with 
  pieces 
  of 
  potato 
  and 
  disturbing 
  the 
  soil 
  as 
  much 
  as 
  possible. 
  

   Odontoptera 
  bidentata, 
  the 
  scalloped 
  hazel 
  moth, 
  which 
  flies 
  in 
  May 
  

   and 
  June, 
  attacked 
  ivy 
  and 
  rhododendron, 
  but 
  also 
  feeds 
  on 
  many 
  

   other 
  plants. 
  When 
  seriously 
  infested, 
  plants 
  should 
  be 
  sprayed 
  

   with 
  arsenate 
  of 
  lead. 
  Hylastes 
  palliatus, 
  GylL, 
  a 
  bark 
  boring 
  beetle, 
  has 
  

   this 
  year 
  proved 
  destructive 
  to 
  Scots 
  Pine, 
  in 
  company 
  with 
  Hylurgus 
  

   (Myelofhilus) 
  piniperda. 
  The 
  economic 
  importance 
  of 
  Hylastes 
  in 
  

   forests 
  is, 
  in 
  the 
  author's 
  opinion, 
  undsrestimated. 
  In 
  April, 
  after 
  

   pairing, 
  the 
  beetles 
  bore 
  into 
  the 
  bark, 
  following 
  the 
  long 
  axis 
  of 
  the 
  

   tree 
  for 
  about 
  lJ-2 
  inches. 
  Eggs 
  are 
  deposited 
  along 
  the 
  sides 
  of 
  

   this 
  gallery 
  and 
  the 
  larvae 
  gnaw 
  out 
  tunnels 
  of 
  their 
  own. 
  Pupation 
  

   occurs 
  at 
  the 
  end 
  of 
  the 
  gallery. 
  There 
  are 
  two 
  generations 
  in 
  the 
  

   year, 
  the 
  April 
  brood 
  emerging 
  in 
  the 
  summer, 
  and 
  the 
  second 
  brood 
  

   wintering 
  in 
  the 
  larval, 
  pupal 
  or 
  imago 
  stage 
  beneath 
  the 
  bark. 
  A 
  

   series 
  of 
  trap 
  stems 
  from 
  the 
  end 
  of 
  March 
  until 
  October 
  is 
  the 
  best 
  

   method 
  of 
  keeping 
  down 
  H. 
  palliatus. 
  Dying 
  trees 
  should 
  not 
  be 
  

   allowed 
  to 
  remain 
  in 
  woods 
  except 
  e.s 
  traps. 
  Bruchus 
  rufimanus, 
  

   (the 
  bean 
  beetle) 
  enters 
  Scotland 
  every 
  year 
  in 
  imported 
  beans. 
  

   Bruchus 
  pisorum, 
  L. 
  (pisi) 
  similarly 
  infests 
  the 
  pea. 
  Fumigation 
  witK 
  

   carbon 
  bisulphide 
  is 
  recommended. 
  Against 
  Schizoneura 
  lanigera^ 
  

   the 
  woolly 
  apple-aphis, 
  the 
  following 
  soda-emulsion 
  wash 
  is 
  recom- 
  

   mended 
  by 
  Pickering 
  : 
  dissolve 
  J 
  lb. 
  iron 
  sulphate 
  in 
  9 
  gallons 
  of 
  water 
  ; 
  

   slake 
  I 
  lb. 
  lime 
  in 
  a 
  little 
  water, 
  stir 
  well 
  and 
  add 
  more 
  water 
  ; 
  run 
  this 
  

   milk 
  of 
  lime 
  into 
  the 
  iron-sulphate 
  solution 
  through 
  a 
  piece 
  of 
  sacking 
  

   or 
  a 
  fine 
  sieve 
  ; 
  add 
  5 
  pints 
  solar 
  distillate 
  paraffin, 
  and 
  water 
  to 
  make 
  

   50 
  gallons, 
  and 
  churn 
  thoroughly 
  ; 
  just 
  before 
  using 
  add 
  2 
  lb. 
  caustic 
  

   soda 
  (powdered). 
  The 
  sprayer's 
  face, 
  eyes 
  and 
  hands 
  should 
  be 
  

   protected 
  against 
  this 
  wash. 
  In 
  the 
  case 
  of 
  root 
  infestation, 
  fumigation 
  

   with 
  bisulphide 
  of 
  carbon 
  is 
  recommended, 
  one 
  fluid 
  ounce 
  being 
  

   injected 
  into 
  the 
  soil 
  in 
  each 
  of 
  four 
  places 
  about 
  two 
  feet 
  from 
  the 
  

   trunk 
  of 
  the 
  apple-tree. 
  This 
  fluid 
  must 
  not 
  touch 
  the 
  roots, 
  but 
  

   the 
  vapour 
  will 
  not 
  injure 
  them. 
  Eriophyes 
  pyri, 
  the 
  pear-leaf 
  blister- 
  

   mite 
  hibernates 
  under 
  the 
  bud 
  scales 
  of 
  the 
  shoots 
  of 
  the 
  year, 
  making 
  

   fresh 
  galls 
  in 
  the 
  spring 
  in 
  which 
  to 
  deposit 
  their 
  eggs. 
  All 
  bhstered 
  

   leaves 
  and 
  shoots 
  should 
  be 
  collected 
  and 
  burnt. 
  In 
  January 
  or 
  

   February, 
  just 
  before 
  the 
  buds 
  burst, 
  Theobald's 
  formula 
  for 
  lime- 
  

   sulphur-soda-salt 
  wash 
  should 
  be 
  used 
  : 
  3-6 
  lb. 
  quicklime 
  and 
  1 
  lb. 
  

   caustic 
  soda 
  to 
  be 
  mixed 
  and 
  then 
  slaked 
  with 
  hot 
  water 
  in 
  which 
  

   3 
  lb. 
  of 
  sulphur 
  has 
  been 
  mixed 
  ; 
  add 
  3 
  lb. 
  salt 
  and 
  water 
  to 
  bring 
  

   up 
  to 
  10 
  gallons 
  ; 
  and 
  this 
  should 
  be 
  followed 
  in 
  spring 
  with 
  a 
  weak 
  

   paraffin 
  emulsion 
  wash, 
  which 
  may 
  also 
  be 
  used 
  after 
  the 
  leaves 
  have 
  

   fallen 
  to 
  kill 
  those 
  mites 
  not 
  yet 
  in 
  the 
  shelter 
  of 
  the 
  bud 
  scales.
