  Natural 
  Enemies. 
  

   No 
  natural 
  enemies 
  of 
  this 
  coccid 
  have 
  been 
  observed 
  preying 
  upon 
  

   it 
  in 
  this 
  country, 
  so 
  far 
  as 
  known 
  to 
  me. 
  Professor 
  Perkins 
  mentions 
  

   the 
  occurrence 
  of 
  a 
  number 
  of 
  hibernating 
  ]ady-birds, 
  on 
  infested 
  trees, 
  

   the 
  most 
  numerous 
  species 
  being 
  Adalia 
  bipunctata^ 
  and 
  suggests 
  that 
  

   they 
  might 
  possibly 
  feed 
  upon 
  it. 
  The 
  lady-birds 
  were 
  very 
  common 
  in 
  

   Albany 
  in 
  the 
  summer 
  of 
  1897, 
  and 
  were 
  noticed 
  in 
  large 
  numbers 
  on 
  

   trees 
  infested 
  with 
  various 
  species 
  of 
  plant-lice, 
  but 
  none 
  were 
  observed 
  

   actually 
  attacking, 
  or 
  in 
  the 
  immediate 
  vicinity 
  of, 
  the 
  Gossyparia. 
  Many 
  

   flies 
  and 
  o'ther 
  insects 
  were 
  seen 
  about 
  infested 
  trees, 
  but 
  they 
  were 
  evi- 
  

   dently 
  attracted 
  by 
  the 
  honey-dew, 
  and 
  could 
  not 
  therefore 
  reasonably 
  be 
  

   considered 
  enemies 
  of 
  this 
  insect. 
  

  

  Remedies. 
  

   Perhaps 
  the 
  best 
  remedy 
  for 
  this 
  pest 
  is 
  spraying 
  with 
  kerosene 
  emul- 
  

   sion 
  or 
  a 
  whale-oil 
  soap 
  solution. 
  The 
  insecticide 
  should 
  be 
  applied 
  

   either 
  in 
  the 
  early 
  spring 
  just 
  after 
  the 
  hibernated 
  forms 
  have 
  molted 
  or 
  

   soon 
  after 
  the 
  young 
  make 
  their 
  appearance. 
  Late 
  in 
  the 
  autumn 
  the 
  

   insects 
  are 
  so 
  well 
  protected 
  that 
  a 
  solution 
  of 
  four 
  times 
  the 
  normal 
  

   strength 
  would 
  be 
  needed 
  for 
  killing 
  them. 
  It 
  might 
  be 
  prefer- 
  

   able 
  to 
  treat 
  the 
  trees 
  at 
  this 
  time, 
  as 
  the 
  insects 
  may 
  then 
  be 
  

   directly 
  reached 
  in 
  the 
  absence 
  of 
  leaves, 
  although 
  a 
  stronger 
  solu- 
  

   tion 
  would 
  be 
  necessary 
  than 
  earlier 
  in 
  the 
  year. 
  Small 
  trees 
  have 
  been 
  

   effectually 
  cleaned 
  by 
  going 
  over 
  them 
  with 
  a 
  stiff 
  brush. 
  The 
  brush 
  

   would 
  be 
  made 
  more 
  effective 
  by 
  dipping 
  it 
  in 
  either 
  kerosene 
  emulsion 
  

   or 
  a 
  whale-oil 
  soap 
  solution 
  from 
  time 
  to 
  time. 
  It 
  may 
  possibly 
  be 
  found 
  

   that 
  a 
  heavy 
  stream 
  of 
  cold 
  water 
  thrown 
  directly 
  on 
  the 
  insects 
  would 
  

   reduce 
  them 
  to 
  harmless 
  numbers, 
  if 
  repeated 
  several 
  times 
  during 
  the 
  

   season. 
  Where 
  convenient, 
  this, 
  from 
  its 
  simplicity, 
  might 
  be 
  preferable 
  

   to 
  other 
  methods.
