  pecan, 
  etc., 
  are 
  native 
  trees, 
  it 
  is 
  probable 
  that 
  when 
  these 
  nuts 
  are 
  

   cultivated 
  they 
  will 
  be 
  attacked 
  by 
  many 
  of 
  the 
  insects 
  which 
  prey 
  

   upon 
  them 
  in 
  nature. 
  This 
  we 
  have 
  found 
  to 
  be 
  true 
  to 
  a 
  consid- 
  

   erable 
  extent 
  in 
  the 
  case 
  of 
  the 
  pecan. 
  Many 
  of 
  the 
  pests 
  of 
  hick- 
  

   ory, 
  for 
  instance, 
  are 
  becoming 
  important 
  enemies 
  of 
  the 
  pecan. 
  

  

  We 
  have 
  few 
  requests 
  for 
  information 
  as 
  to 
  the 
  insect 
  enemies 
  

   of 
  the 
  hazelnut 
  or 
  filbert, 
  practically 
  none 
  as 
  to 
  the 
  almond. 
  I 
  

   surmise 
  that 
  there 
  is 
  comparatively 
  little 
  injury 
  to 
  the 
  two 
  former 
  

   crops 
  in 
  the 
  United 
  States, 
  and 
  that 
  in 
  the 
  case 
  of 
  the 
  almond 
  it 
  

   is 
  largely 
  free 
  from 
  insect 
  pests. 
  The 
  secretary 
  has 
  suggested 
  that 
  

   I 
  make 
  reference 
  particularly 
  to 
  the 
  insect 
  enemies 
  of 
  the 
  walnut. 
  

   We 
  have 
  had 
  complaints 
  of 
  severe 
  injury 
  to 
  walnuts 
  in 
  California 
  

   from 
  the 
  codling 
  moth 
  and 
  walnut 
  aphids. 
  In 
  this 
  state 
  and 
  in 
  the 
  

   arid 
  sections 
  where 
  walnuts 
  are 
  commercially 
  grown, 
  the 
  codling 
  

   moth, 
  the 
  well-known 
  apple 
  pest, 
  has 
  turned 
  its 
  attention 
  to 
  the 
  

   walnut, 
  and 
  under 
  some 
  conditions 
  does 
  serious 
  injury. 
  If 
  walnuts 
  

   are 
  growing 
  adjacent 
  to 
  pears, 
  the 
  marketing 
  of 
  the 
  crop, 
  which 
  

   occurs 
  about 
  the 
  time 
  the 
  second 
  brood 
  of 
  larvae 
  is 
  at 
  its 
  height, 
  

   deprives 
  these 
  insects 
  of 
  further 
  food 
  and 
  they 
  turn 
  their 
  attention 
  

   to 
  the 
  walnut. 
  The 
  walnut 
  plant 
  lice 
  in 
  California 
  have 
  just 
  been 
  

   investigated 
  by 
  an 
  agent 
  of 
  the 
  Bureau 
  of 
  Entomology 
  and 
  we 
  now 
  

   have 
  a 
  paper 
  in 
  press 
  on 
  these 
  insects. 
  We 
  think 
  it 
  propable 
  that 
  

   spraying 
  will 
  be 
  a 
  satisfactory 
  remedy 
  where 
  the 
  trees 
  are 
  not 
  too 
  

   large. 
  

  

  In 
  the 
  East 
  injury 
  is 
  confined 
  largely 
  to 
  certain 
  caterpillars 
  in- 
  

   festing 
  the 
  foliage, 
  as 
  the 
  white-marked 
  tussock 
  moth, 
  the 
  fall 
  web- 
  

   worm, 
  a 
  species 
  of 
  Datana, 
  and 
  occasionally 
  reports 
  of 
  severe 
  injury 
  

   from 
  red 
  spider 
  are 
  received. 
  Rather 
  recently 
  a 
  good 
  deal 
  of 
  inter- 
  

   est 
  has 
  been 
  aroused 
  in 
  the 
  so-called 
  walnut 
  curculio 
  by 
  reason 
  of 
  its 
  

   attacking 
  the 
  shoots 
  and 
  leaf 
  petioles 
  of 
  the 
  Japanese 
  walnut. 
  It 
  

   attacks 
  also 
  other 
  species 
  of 
  walnut, 
  including 
  the 
  English 
  walnut 
  

   and 
  the 
  butternut. 
  This 
  pest 
  has 
  been 
  well 
  treated 
  by 
  Doctor 
  

   Britton 
  in 
  his 
  report 
  as 
  State 
  Entomologist 
  of 
  Connecticut 
  for 
  1912. 
  

  

  While 
  pecans 
  are 
  perhaps 
  not 
  of 
  particular 
  interest 
  to 
  growers 
  

   of 
  nuts 
  in 
  the 
  Northern 
  States, 
  yet 
  brief 
  reference 
  will 
  be 
  made 
  to 
  

   some 
  of 
  the 
  insect 
  enemies 
  of 
  the 
  pecan. 
  There 
  are 
  two 
  excellent 
  

   publications 
  on 
  this 
  subject, 
  as 
  indicated 
  in 
  the 
  list 
  of 
  titles 
  above. 
  

   I 
  should 
  urge 
  all 
  interested 
  in 
  nut 
  culture 
  to 
  obtain 
  these 
  papers, 
  

   since 
  some 
  of 
  the 
  insects 
  treated 
  are 
  quite 
  general 
  feeders 
  and 
  may 
  

   be 
  expected 
  to 
  occur 
  on 
  most 
  all 
  varieties 
  of 
  nuts. 
  

  

  The 
  secretary 
  also 
  has 
  asked 
  that 
  reference 
  be 
  made 
  to 
  the 
  

   hickory 
  bark 
  beetle. 
  This 
  is 
  essentially 
  a 
  forest 
  insect 
  and 
  has
