  that 
  to

   real 
  use 
  the 
  number 
  of

  must 
  be 
  very 
  large 
  and 
  the 
  cost 
  high, 
  

   but 
  if 
  generally 
  practised, 
  the

  would 
  be 
  of 
  the

  The 
  cottony 
  maple 
  scale 
  was 
  very 
  destructive 
  in 
  some 
  areas 
  in 
  the 
  

   southern 
  part 
  of 
  the 
  State 
  on 
  soft 
  maple 
  trees 
  ; 
  generally, 
  the 
  native 
  

   parasites 
  hold 
  this 
  pest 
  in 
  check 
  after 
  one 
  year 
  of 
  abundance. 
  Cut- 
  

   worms 
  caused 
  tremendous 
  losses 
  at 
  a 
  few 
  points, 
  and 
  more 
  or 
  less 
  

   damage 
  everywhere. 
  A 
  poison 
  bran 
  mash 
  made 
  by 
  mixing 
  1 
  lb. 
  

   Paris 
  green 
  with 
  40 
  lbs. 
  dry 
  bran, 
  and 
  moistening 
  this 
  with 
  two 
  quarts 
  

   of 
  cheap 
  molasses 
  and 
  water 
  to 
  a 
  stiff 
  paste, 
  will 
  be 
  effective 
  against 
  

   cutworms, 
  if 
  scattered 
  about 
  the 
  infested 
  spots 
  in 
  the 
  evening. 
  The 
  

   ravages 
  of 
  the 
  onion 
  thrips, 
  Thrips 
  tabaci, 
  as 
  well 
  as 
  of 
  the 
  larva 
  of 
  

   the 
  onion 
  fly, 
  Hylemyia 
  antiqua, 
  have 
  in 
  late 
  years 
  become 
  so 
  

   pronounced 
  as 
  now 
  to 
  threaten 
  this 
  crop 
  with 
  destruction. 
  Trials 
  

   conducted 
  by 
  Dr. 
  H. 
  H. 
  Severin 
  with 
  a 
  sweetened 
  poison-bait 
  spray 
  

   against 
  this 
  fly 
  indicate 
  that 
  the 
  trouble 
  can 
  be 
  considerably 
  checked, 
  

   but 
  additional 
  trials 
  will 
  be 
  needed 
  to 
  see 
  if 
  the 
  mature 
  flies 
  can 
  be 
  

   destroyed 
  before 
  o\dposition 
  begins. 
  The 
  spray 
  consists 
  of 
  : 
  J 
  pint 
  

   common 
  " 
  black- 
  strap 
  " 
  molasses 
  added 
  to 
  a 
  gallon 
  of 
  water 
  with 
  

   one 
  gram 
  of 
  sodium 
  arsenite. 
  Both 
  sexes 
  are 
  readily 
  attracted, 
  and 
  

   are 
  killed 
  within 
  three 
  to 
  ten 
  hours 
  after 
  ingestion 
  of 
  the 
  poison. 
  

   Careless 
  culture 
  undoubtedly 
  hastens 
  the 
  rapid 
  spread 
  of 
  this 
  pest, 
  

   and 
  onion 
  refuse, 
  consisting 
  of 
  tops, 
  undersized 
  bulbs, 
  etc., 
  should 
  

   on 
  no 
  account 
  be 
  left 
  on 
  the 
  field 
  or 
  spread 
  on 
  it 
  and 
  dug 
  in 
  as 
  manure. 
  

   The 
  San 
  Jose 
  scale 
  has 
  occurred 
  in 
  a 
  few 
  new 
  localities, 
  but 
  immediate 
  

   measures 
  succeeded 
  in 
  exterminating 
  it 
  before 
  it 
  spread.

  Five 
  moth 
  traps, 
  set 
  in 
  a 
  vineyard 
  in 
  the 
  severely 
  infested 
  district 
  

   of 
  Kleinmacher 
  in 
  Luxemburg, 
  captured 
  498 
  Clysia 
  ambiguella 
  in 
  the 
  

   24 
  days 
  of 
  the 
  flight 
  in 
  May 
  and 
  June. 
  The 
  bait 
  consisted 
  of 
  equal 
  

   parts 
  of 
  water 
  sweetened 
  with 
  sugar, 
  old 
  beer 
  and 
  old 
  cider, 
  and 
  was 
  

   replenished 
  every 
  2 
  or 
  3 
  days. 
  The 
  odour 
  of 
  nicotin 
  drives 
  the 
  moths 
  

   away, 
  and 
  spraying 
  with 
  nicotin 
  caused 
  an 
  instant 
  drop 
  in 
  the 
  catches, 
  

   the 
  weather 
  remaining 
  unchanged. 
  Though 
  useless 
  on 
  cold 
  and 
  rainy 
  

   days, 
  traps 
  are 
  valuable 
  in 
  severely 
  infested 
  districts 
  and, 
  given 
  

   suitable 
  weather, 
  a 
  total 
  catch 
  of 
  150 
  moths 
  per 
  trap 
  during 
  the 
  flight 
  

   is 
  certain, 
  or 
  45,000 
  for 
  300 
  traps, 
  which 
  is 
  the 
  number 
  one 
  man 
  can 
  

   attend 
  to 
  in 
  a 
  day.
