  held 
  in 
  check 
  by 
  the 
  Austrahan 
  Cocciiiellid, 
  Novius 
  cardinalis, 
  suppKed 
  

   by 
  the 
  State 
  Insectary. 
  

  

  The 
  peach 
  borer, 
  Sanninoidea 
  opalescens, 
  is 
  rather 
  limited 
  in 
  its 
  

   distribution, 
  being 
  found 
  in 
  the 
  Santa 
  Clara 
  Valley, 
  Alameda 
  and 
  San 
  

   Mateo 
  counties, 
  and 
  slight 
  infestations 
  at 
  Ventura 
  and 
  Riverside. 
  It 
  

   attacks 
  chiefly 
  the 
  peach, 
  apricot, 
  plum, 
  prune 
  and 
  cherry. 
  The 
  eggs 
  

   are 
  laid 
  on 
  the 
  trunks 
  a 
  few 
  inches 
  above 
  the 
  surface 
  of 
  the 
  soil 
  and 
  the 
  

   newly 
  hatched 
  larva 
  bores 
  through 
  the 
  bark. 
  The 
  exuding 
  gum 
  indi- 
  

   cates 
  the 
  presence 
  of 
  the 
  larvae, 
  which 
  remain 
  in 
  their 
  burrows 
  during 
  

   the 
  winter 
  months. 
  Control 
  methods 
  include 
  the 
  use 
  of 
  the 
  resistant 
  

   Myrobolan 
  cherry-plum 
  as 
  a 
  stock, 
  protective 
  washes 
  of 
  some 
  crude 
  

   oil 
  mixture, 
  lime-sulphur-salt 
  mixture, 
  digging 
  out 
  the 
  worms 
  or 
  

   kilhng 
  them 
  with 
  a 
  crooked 
  w^ire. 
  The 
  use 
  of 
  hard 
  asphaltum, 
  grades 
  

   C 
  and 
  D, 
  applied 
  warm 
  to 
  the 
  tree- 
  trunks 
  from 
  5 
  to 
  6 
  inches 
  below 
  and 
  

   above 
  the 
  surface 
  of 
  the 
  soil 
  with 
  a 
  brush, 
  has 
  been 
  recommended. 
  

   Two 
  coats 
  are 
  put 
  on, 
  preventing 
  the 
  entrance 
  or 
  exit 
  of 
  many 
  of 
  the 
  

   insects. 
  The 
  eggs 
  of 
  the 
  brown 
  day 
  moth, 
  Pseudohazis 
  eglantereina, 
  

   Boisd., 
  are 
  salmon 
  coloured 
  and 
  laid 
  in 
  clusters 
  around 
  the 
  small 
  

   twigs 
  in 
  early 
  spring 
  ; 
  these 
  should 
  be 
  destroyed 
  and 
  arsenical 
  sprays 
  

   used, 
  when 
  the 
  larvae 
  are 
  numerous 
  enough 
  to 
  do 
  much 
  damage. 
  

   They 
  are 
  voracious 
  feeders 
  on 
  various 
  fruits 
  and 
  bushes. 
  Mention 
  

   is 
  also 
  made 
  of 
  the 
  rose 
  aphis, 
  which 
  a 
  soapy 
  solution 
  of 
  tobacco 
  

   spray 
  will 
  easily 
  destroy, 
  and 
  of 
  the 
  rose 
  scale, 
  found 
  in 
  all 
  stages 
  

   throughout 
  the 
  year 
  infesting 
  rose, 
  raspberry 
  and 
  blackberry 
  canes. 
  

   The 
  eggs 
  are 
  hard 
  to 
  kill 
  and 
  successive 
  sprayings 
  w^ith 
  kerosene 
  

   emulsion 
  are 
  necessary 
  to 
  control 
  it. 
  Badly 
  infested 
  canes 
  should 
  be 
  

   cut 
  out 
  and 
  burned. 
  

  

  The 
  raspberry 
  horntail, 
  Hartigia 
  cressoni, 
  is 
  a 
  sawfly, 
  the 
  larvae 
  

   of 
  which 
  burrow 
  into 
  the 
  canes 
  of 
  the 
  raspberry, 
  blackberry, 
  

   rose 
  and 
  loganberry. 
  The 
  winter 
  is 
  spent 
  in 
  the 
  larval 
  and 
  resting 
  

   stages 
  within 
  the 
  canes, 
  adults 
  emerging 
  in 
  April. 
  The 
  eggs 
  are 
  inserted 
  

   in 
  the 
  tips 
  of 
  young 
  shoots 
  and 
  soon 
  hatch. 
  Having 
  killed 
  the 
  tips 
  the 
  

   larvae 
  make 
  their 
  way 
  down 
  into 
  the 
  canes. 
  Control 
  may 
  be 
  attempted 
  

   by 
  destroying 
  the 
  soft 
  eggs 
  by 
  slight 
  pressure 
  before 
  they 
  hatch, 
  and 
  

   cutting 
  out 
  infested 
  canes. 
  

  

  The 
  larvae 
  of 
  the 
  strawberry 
  crown 
  moth, 
  Aegeria 
  rictilans, 
  work 
  

   within 
  the 
  stems 
  near 
  the 
  base 
  or 
  roots 
  of 
  the 
  host. 
  The 
  roots 
  and 
  

   canes 
  of 
  raspberries 
  and 
  blackberries 
  are 
  sometimes 
  attacked, 
  the 
  

   adult 
  laying 
  its 
  eggs 
  soon 
  after 
  emerging 
  in 
  April. 
  In 
  irrigated 
  

   districts 
  infested 
  fields 
  should 
  be 
  submerged 
  for 
  four 
  or 
  five 
  days 
  

   after 
  the 
  crop 
  is 
  harvested.

  G. 
  P. 
  Weldon 
  reports 
  that 
  Anarsia 
  lineatella 
  (peach 
  twig 
  borer) 
  

   was 
  taken 
  hibernating 
  in 
  the 
  forks 
  of 
  almond 
  trees 
  at 
  Paso 
  Robles, 
  

   Cal., 
  on 
  21st 
  January. 
  The 
  eggs 
  of 
  Bryohia 
  pratensis 
  (brown 
  or 
  

   almond 
  mite) 
  were 
  also 
  found 
  abundantly 
  near 
  Banning 
  on 
  almond 
  

   trees. 
  A 
  severe 
  infestation 
  of 
  Sanninoidea 
  opalescens 
  (peach 
  

   borer) 
  was 
  found 
  recently 
  in 
  Riverside 
  Coimty, 
  this 
  being 
  the 
  first 
  

   report 
  of 
  it 
  in 
  that 
  county. 
  Tortrix 
  citrana 
  (the 
  orange 
  tortrix) 
  is
