  Leaves 
  of 
  a 
  Chickasaw 
  plum 
  from 
  Muncy, 
  Pa., 
  are 
  deformed 
  with 
  

   galls 
  showing 
  on 
  both 
  surfaces 
  of 
  the 
  leaf, 
  produced 
  by 
  a 
  gallmite 
  

   which 
  is 
  seen 
  under 
  a 
  powerful 
  glass. 
  Judging 
  from 
  the 
  character 
  ot 
  

   the 
  gall, 
  it 
  is 
  identical 
  with 
  that 
  oi 
  Phytoptus 
  pruni 
  Amerl., 
  which 
  has 
  

   not 
  been 
  previously 
  detected 
  in 
  this 
  country. 
  For 
  the 
  destruction 
  ot 
  

   the 
  mite, 
  hand-picking 
  and 
  burning 
  the 
  infested 
  leaves 
  early 
  in 
  the 
  

   season, 
  and 
  winter 
  spraying 
  with 
  kerosene 
  emulsion 
  are 
  recommended.

  The

  The 
  canker-worm, 
  Anisopteryxvernata 
  (Peck), 
  is 
  defoliating 
  orchards 
  

   in 
  Amenia, 
  N. 
  Y., 
  where 
  it 
  has 
  previously 
  been 
  abundant. 
  It 
  is 
  prov- 
  

   ing 
  quite 
  resistant 
  to 
  Paris 
  green, 
  and 
  one 
  pound 
  of 
  the 
  green 
  to 
  100 
  

   gallons 
  of 
  water 
  has 
  been 
  required 
  for 
  killing 
  it. 
  Its 
  habit 
  of 
  dropping 
  

   from 
  the 
  foliage 
  and 
  being 
  carried 
  on 
  its 
  thread 
  by 
  the 
  wind 
  to 
  other 
  

   trees 
  is 
  noticed. 
  It 
  is 
  known 
  in 
  Amenia, 
  as 
  the 
  ''fire 
  worm," 
  as 
  the 
  

   trees 
  after 
  the 
  infestation, 
  look 
  as 
  if 
  they 
  had 
  been 
  swept 
  by 
  fire.

  Fruit

  Aphides.

  Some 
  black 
  aphides 
  on 
  cherry 
  from 
  East 
  Hartford, 
  N. 
  Y., 
  are 
  iden- 
  

   tified 
  as 
  the 
  cherry-tree 
  aphis, 
  Myzus 
  cerasi 
  (Fabr.), 
  and 
  the 
  green 
  ones 
  

   on 
  plum 
  as 
  Aphis 
  prunifolice 
  Fitch. 
  The 
  former 
  is 
  a 
  common 
  and 
  

   widely 
  distributed 
  pest, 
  while 
  the 
  latter 
  is 
  much 
  less 
  so. 
  Spraying 
  the 
  

   plant-Hce 
  with 
  whale-oil 
  soap 
  solution 
  or 
  strong 
  tobacco 
  water 
  on 
  

   their 
  first 
  appearance 
  is 
  effective. 
  After 
  the 
  leaves 
  curl, 
  the 
  spray 
  is 
  not 
  

   effective. 
  The 
  Syrphid 
  larvae 
  found 
  preying 
  on 
  the 
  aphides 
  would 
  

   probably 
  soon 
  destroy 
  them 
  all.

  The 
  larvae 
  of 
  the 
  first 
  brood 
  are 
  now 
  descending 
  for 
  pupation, 
  and 
  

   by 
  killing 
  them 
  with 
  hot 
  water 
  or 
  kerosene, 
  the 
  ravages 
  of 
  the 
  second 
  

   brood 
  may 
  be 
  largely 
  prevented. 
  This 
  method 
  is 
  simple, 
  while 
  general 
  

   spraying 
  is 
  impracticable.
