  Towards 
  the 
  end 
  of 
  May, 
  just 
  before 
  the 
  adult 
  insect 
  appears, 
  the 
  canes 
  

   should 
  be 
  again 
  inspected 
  and 
  stems 
  bearing 
  galls 
  destroyed. 
  Beinbecia 
  

   hylaeiformis 
  appears 
  as 
  an 
  adult 
  from 
  June 
  to 
  August. 
  Its 
  larva 
  bores 
  

   into 
  the 
  stems 
  of 
  the 
  raspberry 
  and 
  sometimes 
  perforates 
  the 
  root, 
  

   where 
  it 
  is 
  far 
  more 
  difficult 
  to 
  deal 
  with. 
  Infested 
  stems 
  should 
  be 
  

   cut 
  and 
  burnt. 
  Bracon 
  minutator, 
  Colpognathus 
  celerator, 
  Centeterus 
  

   major, 
  and 
  Meniscus 
  bilineatus 
  are 
  some 
  of 
  the 
  many 
  parasites 
  of 
  

   this 
  pest. 
  Pteronus 
  ribesii 
  is 
  the 
  chief 
  Tenthredinid 
  pest 
  of 
  the 
  goose- 
  

   berry. 
  This 
  saw-fly 
  has 
  two 
  generations, 
  the 
  imagines 
  appearing 
  in 
  

   April 
  or 
  May, 
  and 
  again 
  in 
  July. 
  The 
  first 
  generation 
  of 
  larvae 
  appears 
  

   in 
  May 
  and 
  June, 
  the 
  second 
  in 
  August 
  and 
  September. 
  Fortunately 
  

   a 
  large 
  number 
  of 
  parasites 
  attack 
  P. 
  ribesii, 
  including 
  the 
  Tachinid 
  

   fly, 
  Degeeria 
  flavicans 
  ; 
  the 
  Proctotrupids, 
  Diplolepis 
  {Cleptes) 
  nitidulus 
  

   and 
  Omalus 
  auratus 
  ; 
  the 
  Ichneumons, 
  Tryphon 
  ambiguus, 
  Mesoleius 
  

   (Tryplion) 
  armillatorius, 
  M. 
  bipunctatus, 
  M. 
  grossulariae, 
  Polysphincta 
  

   ribesii 
  and 
  Perilissus 
  limitaris 
  ; 
  and 
  the 
  Bracon, 
  Pygostolus 
  sticticus. 
  

   A 
  cheap 
  and 
  satisfactory 
  control 
  measure 
  consists 
  of 
  shaking 
  the 
  

   larvae 
  on 
  to 
  sheets 
  spread 
  on 
  the 
  ground, 
  or 
  the 
  bushes 
  may 
  be 
  sprayed 
  

   with 
  water 
  and 
  a 
  mixture 
  of 
  lime 
  and 
  soot 
  may 
  then 
  be 
  put 
  on 
  the 
  

   foHage. 
  Emulsions 
  of 
  petroleum 
  and 
  soap 
  also 
  give 
  good 
  results. 
  

   Emphytus 
  grossulariae, 
  MacropJiyga 
  ribis, 
  Nematus 
  consobrinus, 
  and 
  

   Perineura 
  solitaria 
  are 
  other 
  Tenthredinids 
  injurious 
  to 
  the 
  gooseberry 
  

   and 
  should 
  be 
  dealt 
  with 
  in 
  the 
  same 
  way. 
  Many 
  of 
  these 
  larvae, 
  in 
  

   particular 
  those 
  of 
  Emphytus, 
  pass 
  the 
  winter 
  in 
  stems 
  of 
  which 
  the 
  

   pith 
  is 
  easy 
  to 
  pierce, 
  but 
  they 
  do 
  not 
  otherwise 
  attack 
  the 
  raspberry, 
  

   vine, 
  etc., 
  which 
  shelters 
  them, 
  and 
  cannot 
  be 
  considered 
  to 
  be 
  pests 
  

   of 
  these 
  plants. 
  The 
  adult 
  Abraxas 
  grossulariata 
  appears 
  from 
  June 
  

   to 
  August 
  ; 
  it 
  oviposits 
  on 
  the 
  leaves 
  and 
  branches 
  of 
  the 
  gooseberry, 
  

   the 
  larva 
  hatches 
  in 
  September 
  and 
  feeds 
  on 
  the 
  leaves 
  until 
  it 
  hiber- 
  

   nates, 
  the 
  main 
  injury 
  occurring 
  in 
  spring. 
  The 
  larvae 
  of 
  A. 
  grossu- 
  

   lariata 
  are 
  controlled 
  by 
  numerous 
  Hymenoptera, 
  including 
  Ichneumon 
  

   comitator, 
  I. 
  scutellator, 
  I. 
  bilineatus, 
  I. 
  trilineatus, 
  I. 
  ochropis, 
  Pimpla 
  

   examinator, 
  P. 
  instigator, 
  and 
  the 
  Bracons 
  Microgaster 
  rufiventris, 
  

   Apanteles 
  (Microgaster) 
  gagates, 
  and 
  A. 
  congestus 
  {M. 
  perspicuus). 
  

   The 
  life-history 
  of 
  the 
  V-moth, 
  Halia 
  wavaria, 
  is 
  similar 
  to 
  that 
  of 
  

   A. 
  grossulariata. 
  It 
  occasionally 
  attacks 
  the 
  fruit. 
  Its 
  parasites 
  have 
  

   not 
  been 
  observed. 
  The 
  Geometers, 
  Eupithecia 
  assimilata, 
  Lygris 
  

   associata, 
  and 
  other 
  Lepidoptera 
  are 
  also 
  found 
  on 
  the 
  gooseberry, 
  

   while 
  Cidaria 
  albicillata 
  occurs 
  on 
  the 
  raspberry. 
  The 
  control 
  measures 
  

   used 
  for 
  Tenthredinids 
  are 
  also 
  applicable 
  here. 
  Aegeria 
  (Sesia) 
  tipu- 
  

   liformis 
  larvae 
  live 
  in 
  the 
  stems 
  of 
  the 
  red 
  gooseberry 
  and 
  of 
  the 
  black 
  

   currant. 
  Pupation 
  takes 
  place 
  in 
  the 
  bore-hole 
  and 
  the 
  imago 
  emerges 
  

   in 
  May. 
  Control 
  measures 
  are 
  the 
  same 
  as 
  for 
  Agrilus 
  chrysoderes.

  When 
  the 
  larva 
  of 
  the 
  Tineid 
  moth, 
  Endrosis 
  lactella, 
  occurs 
  in 
  horse- 
  

   beans, 
  it 
  may 
  be 
  destroyed 
  by 
  heating 
  at 
  a 
  temperature 
  of 
  from 
  122° 
  

   to 
  140° 
  Fahr., 
  for 
  a 
  sufficient 
  time 
  to 
  ensure 
  that 
  each 
  seed 
  is 
  heated 
  

   right 
  through. 
  As 
  E. 
  lactella 
  attacks 
  many 
  varieties 
  of 
  grain, 
  store- 
  

   rooms 
  should 
  be 
  fumigated 
  for 
  48 
  hours 
  with 
  sulphur.
