  severely 
  infested 
  by 
  

   Aphids 
  a

  syringing

   useful. 
  Various 
  species 
  of 
  Rhodites 
  form 
  galls 
  on 
  the 
  stems 
  and 
  

   leaves 
  of 
  roses. 
  Rhodites 
  rosae 
  attacks 
  Rosa

  and 
  other 
  wild 
  

   roses 
  ; 
  R.

  Beyrins., 
  prefers 
  Rosa 
  ruhiginosa 
  ; 
  roses 
  of 
  the 
  

   centifolia 
  variety 
  are 
  attacked 
  by 
  R. 
  centifolia. 
  All 
  shoots 
  showing 
  

   galls 
  should 
  be 
  destroyed.

  Blennocampa 
  pusilla 
  and 
  Selandria

  attack 
  the 
  foHage, 
  as 
  also 
  do 
  the 
  moths 
  Eucosma 
  

   (Grapholita) 
  tripunctana, 
  Eucosma 
  roborana, 
  Tortrix 
  bergmanniana 
  

   and 
  Coleophora 
  gryphipennella. 
  Another 
  serious 
  pest 
  of 
  the 
  

   fohage 
  is 
  Cecidomyia 
  rosae, 
  the 
  females 
  of 
  which 
  fly 
  oviposit 
  at 
  the 
  

   beginning 
  of 
  summer 
  on 
  the 
  leaves 
  while 
  still 
  in 
  the 
  bud. 
  Several 
  

   generations 
  occur 
  in 
  one 
  summer, 
  and 
  the 
  insect 
  hibernates 
  in 
  the 
  

   earth 
  as 
  a 
  pupa. 
  The 
  Jassid, 
  Typhlocyba 
  rosae, 
  the 
  females 
  of 
  which 
  

   deposit 
  their 
  eggs 
  in 
  autumn 
  on 
  the 
  ends 
  of 
  the 
  shoots, 
  chiefly 
  

   attacks 
  those 
  varieties 
  which 
  are 
  hghtly 
  pruned. 
  

  

  Various 
  insecticides 
  can 
  be 
  apphed 
  against 
  insect 
  pests, 
  the 
  

   larvae 
  of 
  which 
  feed 
  on 
  the 
  fohage, 
  including 
  Paris 
  green, 
  djipsin 
  

   and 
  barium 
  chloride. 
  The 
  following 
  recipe 
  is 
  given 
  for 
  the 
  prepara- 
  

   tion 
  of 
  djipsin 
  : 
  about 
  1 
  oz. 
  of 
  sodium 
  arsenate 
  and 
  3 
  oz. 
  of 
  lead 
  

   arsenate 
  are 
  dissolved 
  separately 
  in 
  boiling 
  water 
  in 
  earthen- 
  

   ware 
  or 
  glass 
  vessels 
  and 
  then 
  mixed 
  together 
  in 
  another 
  vessel 
  

   containing 
  so 
  much 
  water 
  that 
  the 
  whole 
  should 
  form 
  60 
  gallons. 
  

  

  The 
  beetles, 
  Phyllopertha 
  horticola, 
  Anthonomus 
  rubi 
  and 
  Cetonia 
  

   aurata, 
  eat 
  the 
  buds 
  and 
  blossoms 
  and 
  are 
  best 
  kept 
  down 
  by 
  hand- 
  

   picking. 
  

  

  Useful 
  insects 
  mentioned 
  include 
  Coccinella 
  septempunctata, 
  L., 
  

   and 
  Chrysopa

  which 
  destroy 
  aphids.

   that

  as 
  the

  it 
  

   appears 
  that

  In 
  the 
  Bohemian 
  forests, 
  Hylobius 
  abietis 
  is 
  a 
  constant 
  pest 
  ; 
  

   Myelophilus 
  (Hylastes) 
  minor, 
  M. 
  piniperda 
  and 
  in 
  some 
  spots, 
  Hylastes 
  

   palliatus 
  are 
  fairly 
  abundant. 
  The 
  nun-moth, 
  Lymantria 
  monacha, 
  

   is 
  only 
  occasionally 
  seen.
