  Insecticides 
  are 
  practically 
  useless 
  either 
  against 
  the 
  beetles 
  or 
  the 
  

   larvae, 
  and 
  as 
  the 
  Ficus 
  trees 
  are 
  of 
  considerable 
  size, 
  efficient 
  spraying 
  

   of 
  the 
  leaves 
  and 
  young 
  shoots, 
  to 
  prevent 
  the 
  attack 
  of 
  the 
  beetles, 
  

   is 
  by 
  no 
  means 
  easy. 
  Spraying 
  a 
  log 
  of 
  Ficus 
  wood 
  with 
  1 
  per 
  cent. 
  

   Paris 
  green 
  did 
  not 
  prevent 
  the 
  beetles 
  from 
  ovipositing 
  on 
  it 
  ; 
  twelve 
  

   larvae 
  being 
  subsequently 
  found 
  in 
  it. 
  Tarring 
  the 
  tapping-cuts 
  is 
  

   apparently 
  of 
  no 
  avail, 
  as 
  the 
  beetles 
  were 
  constantly 
  found 
  on 
  the 
  

   tarred 
  spots, 
  but 
  carbohneum 
  produced 
  a 
  better 
  result, 
  possibly 
  owing 
  

   to 
  its 
  strong 
  odour, 
  and 
  from 
  experiments, 
  treatment 
  of 
  the 
  tapping 
  

   cuts 
  with 
  50 
  per 
  cent, 
  carbohneum 
  will 
  probably 
  suffice 
  to 
  kill 
  both 
  

   eggs 
  and 
  larvae, 
  the 
  best 
  time 
  to 
  apply 
  the 
  remedy 
  being 
  3 
  weeks 
  

   after 
  tapping. 
  The 
  injection 
  of 
  carbon 
  bisulphide 
  is 
  not 
  practicable 
  

   as 
  it 
  involves 
  the 
  enlargement 
  of 
  the 
  outer 
  opening 
  in 
  each 
  case.

  Eriofhyes 
  pyri, 
  Pgst., 
  the 
  leaf 
  -blister 
  mite, 
  was 
  the 
  most 
  injurious 
  

   insect 
  pest 
  of 
  apples 
  and 
  pears 
  in 
  the 
  Bitter 
  Root 
  Valley 
  in 
  1913, 
  

   except 
  in 
  orchards 
  in 
  which 
  the 
  strong 
  lime-sulphur 
  spray 
  had 
  been 
  

   used 
  just 
  before 
  the 
  buds 
  opened. 
  Rhizoglyphus 
  hyacinthi, 
  Boisd., 
  

   the 
  bulb 
  mite, 
  was 
  found 
  in 
  a 
  shipment 
  of 
  imported 
  bulbs, 
  and 
  

   Eriophyes 
  padi, 
  Nal., 
  the 
  plum 
  gall 
  mite, 
  was 
  very 
  abundant 
  in 
  the 
  

   eastern 
  half 
  of 
  the 
  State. 
  It 
  distorts 
  the 
  leaves 
  of 
  both 
  cultivated 
  

   and 
  wild 
  plum, 
  and 
  in 
  many 
  instances 
  reduces 
  the 
  fruit-crop. 
  Some 
  

   injury 
  to 
  sweet 
  peas 
  and 
  clover 
  was 
  caused 
  by 
  the 
  clover 
  mite 
  {Bryobia 
  

   pratensis, 
  Garman), 
  but 
  it 
  attracted 
  most 
  attention 
  as 
  a 
  household 
  

   pest. 
  Troctes 
  divinatoria, 
  F., 
  the 
  book-louse, 
  attacked 
  wheat. 
  The 
  

   most 
  injurious 
  grasshopper 
  was 
  Melanoplus 
  hivittatus, 
  Scud. 
  ; 
  autumn 
  

   ploughing 
  to 
  destroy 
  the 
  eggs 
  and 
  the 
  use 
  of 
  hopperdozers 
  against 
  the 
  

   young 
  stages 
  were 
  the 
  most 
  effective 
  control 
  measures. 
  Haploihrips 
  

   statices, 
  Holiday, 
  damaged 
  the 
  seed-crop 
  in 
  the 
  heads 
  of 
  red-clover 
  ; 
  

   the 
  chinch-bug 
  {Blissus 
  leucoptem, 
  Say) 
  was 
  less 
  abundant 
  than 
  

   formerly 
  ; 
  a 
  swarm 
  of 
  Lygaeus 
  lateralis, 
  Dall., 
  occurred 
  in 
  June, 
  but 
  

   disappeared 
  in 
  a 
  day 
  or 
  two 
  without 
  injuring 
  the 
  vegetation. 
  The 
  

   false 
  chinch-bug 
  {Nysius 
  angustatus, 
  Uhl.), 
  did 
  considerable 
  damage 
  

   to 
  garden 
  crops, 
  but 
  Anthocorismelanocerus, 
  Reut., 
  and 
  Leucopis 
  griseolay 
  

   Fall., 
  were 
  useful, 
  being 
  predaceous 
  on 
  plant-lice. 
  The 
  green 
  apple- 
  

   aphis 
  {Aphis 
  pomi, 
  De 
  G.), 
  was 
  unusually 
  abundant, 
  and 
  in 
  some 
  

   instances 
  even 
  the 
  fruit 
  was 
  attacked. 
  So 
  many 
  enquiries 
  were 
  

   received 
  concerning 
  Aphis 
  brassicae, 
  L., 
  that 
  a 
  circular 
  was 
  pre- 
  

   pared. 
  [See

  pp. 
  4-5.] 
  Pemphigus 
  betaey 
  

   Doane, 
  the 
  sugar-beet 
  root-louse, 
  caused 
  more 
  injury 
  than 
  for 
  several 
  

   years, 
  and 
  in 
  some 
  fields 
  it 
  was 
  estimated 
  that 
  the 
  weight 
  of 
  the 
  crop 
  

   was 
  reduced 
  by 
  one- 
  third. 
  Toxoptera 
  graminum, 
  Rond., 
  was 
  found 
  

   in 
  several 
  grain 
  fields, 
  but 
  did 
  little 
  damage. 
  The 
  oyster-shell 
  scale 
  

   (Lepidosaphes 
  ulmi, 
  L.), 
  is 
  the 
  most 
  injurious 
  scale-insect 
  in 
  Montana, 
  

   and 
  during 
  the 
  year 
  attempts 
  were 
  made 
  to 
  ascertain 
  whether 
  tw^o 
  

   dilute 
  sprays 
  for 
  apple-scab 
  would 
  also 
  control 
  the 
  scale; 
  

   it 
  was 
  found 
  to 
  be 
  much 
  reduced 
  by 
  such 
  treatment, 
  but 
  the 
  strong
