  in 
  an 
  Act 
  approved 
  4th 
  March 
  1881, 
  the 
  mention 
  of 
  the 
  word 
  quaran- 
  

   tine 
  as 
  applied 
  strictly 
  to 
  horticultural 
  material 
  is 
  found 
  for 
  the 
  first 
  

   time. 
  The 
  San 
  Jose 
  scale, 
  the 
  codling 
  moth, 
  the 
  cottony 
  cushion 
  

   scale, 
  and 
  the 
  Mediterranean 
  fruit-fly 
  are 
  all 
  mentioned 
  as 
  having 
  

   caused 
  a 
  reduction 
  of 
  agricultural 
  assessment 
  values 
  or 
  necessitated 
  

   the 
  amending 
  of 
  the 
  quarantine 
  regulations 
  in 
  the 
  State. 
  The 
  quaran- 
  

   tine 
  law, 
  as 
  affecting 
  shippers, 
  purchasers, 
  planters 
  of 
  trees 
  from 
  

   outside 
  the 
  state, 
  and 
  growers 
  of 
  agricultural 
  and 
  horticultural 
  products 
  

   within 
  California 
  itself, 
  is 
  examined. 
  The 
  staff 
  available 
  for 
  the 
  service 
  

   of 
  the 
  State 
  agricultural 
  quarantine 
  law 
  is 
  compared 
  with 
  that 
  for 
  

   carrying 
  out 
  the 
  Fish 
  and 
  Game 
  law. 
  Under 
  the 
  former 
  there 
  are 
  

   9 
  quarantine 
  officers, 
  44 
  quarantine 
  guardians 
  and 
  144 
  county 
  

   inspectors, 
  making 
  a 
  total 
  of 
  197 
  as 
  compared 
  with 
  a 
  total 
  of 
  773 
  

   under 
  the 
  latter.

  Until 
  a 
  few 
  years 
  ago 
  the 
  cherry- 
  grower 
  had 
  little 
  to 
  complain 
  of 
  

   in 
  the 
  way 
  of 
  pests. 
  Thrips 
  have 
  recently 
  become 
  a 
  menace 
  and 
  are 
  

   doing 
  a 
  great 
  amount 
  of 
  damage 
  to 
  the 
  orchards, 
  and 
  while 
  the 
  adults 
  

   destroy 
  blossoms 
  and 
  fruit, 
  the 
  most 
  serious 
  injury 
  is 
  caused 
  by 
  the 
  

   larvae, 
  which 
  eat 
  the 
  leaf 
  buds 
  as 
  they 
  unfold. 
  Deep 
  ploughing 
  in 
  

   the 
  autumn 
  is 
  one 
  method 
  of 
  control, 
  but 
  spraying 
  with 
  a 
  tobacco-wash 
  

   several 
  times 
  during 
  March 
  and 
  April 
  is 
  more 
  effective. 
  The 
  peach- 
  

   borer, 
  Sanninoidea 
  opalescens, 
  is 
  also 
  troublesome 
  to 
  the 
  cherry- 
  

   grower 
  ; 
  it 
  is 
  found 
  even 
  in 
  the 
  trees 
  as 
  they 
  come 
  from 
  the 
  nursery, 
  

   but 
  usually 
  orchards 
  will 
  not 
  have 
  to 
  be 
  examined 
  until 
  the 
  trees 
  are 
  

   three 
  years 
  old 
  ; 
  they 
  must 
  then 
  be 
  dug 
  for 
  every 
  year. 
  If 
  the 
  holes 
  

   at 
  the 
  base 
  of 
  the 
  trees 
  are 
  opened 
  early 
  in 
  autumn 
  and 
  left 
  open 
  till 
  

   May, 
  the 
  bark 
  on 
  the 
  roots 
  w^ill 
  harden 
  and 
  the 
  young 
  grub 
  cannot 
  

   penetrate 
  it 
  so 
  easily 
  ; 
  a 
  mixture 
  of 
  very 
  thick 
  whitewash 
  applied 
  

   to 
  the 
  roots 
  does 
  good. 
  A 
  crude 
  oil 
  spray 
  can 
  be 
  used 
  successfully 
  

   against 
  the 
  Italian 
  scale, 
  Aulacaspis 
  pentagona, 
  and 
  cherry 
  scale, 
  

   A. 
  forbesi, 
  and 
  red 
  spider 
  can 
  also 
  be 
  eradicated 
  by 
  spraying.

  The 
  minute 
  false 
  chinch-bug, 
  Nysius 
  angustatiis 
  minutus, 
  has 
  been 
  

   found 
  attacking 
  the 
  foliage 
  of 
  young 
  peach 
  and 
  apricot 
  trees, 
  and 
  

   Tetranychus 
  simplex. 
  Banks, 
  is 
  damaging 
  cypress, 
  maple, 
  and 
  other 
  

   shade 
  trees. 
  The 
  pear-leaf 
  russet 
  mite, 
  Epitrimerus 
  piri, 
  has 
  been 
  

   taken 
  quite 
  commonly 
  on 
  pear 
  and 
  peach 
  leaves. 
  Tetranychus 
  

   himaculatiis 
  has 
  been 
  injurious 
  to 
  prune 
  and 
  almond 
  trees 
  after 
  

   1st 
  July, 
  but 
  previous 
  to 
  that 
  time, 
  Bryobia 
  pratensis 
  was 
  the 
  most 
  

   common 
  mite 
  in 
  orchards 
  ; 
  the 
  woolly 
  aphis, 
  Schizoneura 
  lanigera, 
  

   is 
  of 
  very 
  common 
  occurrence 
  on 
  the 
  roots 
  of 
  Bartlett 
  pear 
  trees. 
  

   The 
  black 
  scale, 
  Saissetia 
  oleae, 
  has 
  been 
  reported 
  as 
  occurring 
  in 
  

   exceptional 
  numbers 
  on 
  walnuts 
  in 
  the 
  Goleta 
  district, 
  the 
  infestation, 
  

   which 
  is 
  confined 
  chiefly 
  to 
  the 
  small 
  limbs, 
  being 
  the 
  heaviest 
  ever 
  

   observed 
  ; 
  over 
  90 
  per 
  cent, 
  were 
  parasitised 
  by 
  the 
  Chalcid, 
  Scutellista 
  

   cyanea, 
  Motsch., 
  both 
  larvae 
  and 
  pupae 
  occurring 
  on 
  July 
  14th
