  fruit 
  and 
  the 
  latter 
  were 
  able 
  to 
  ripen 
  before 
  the 
  larvae 
  had 
  grown, 
  

   up 
  sufficiently 
  to 
  injure 
  them. 
  Some 
  bushes 
  of 
  raspberries 
  were 
  

   covered 
  early 
  in 
  spring 
  with 
  gauze, 
  in 
  connection 
  with 
  some 
  obser- 
  

   vations 
  on 
  Incurvaria 
  rubiella, 
  Bjerk., 
  and 
  these 
  fruits 
  were 
  also 
  not 
  

   damaged 
  by 
  the 
  beetles 
  and 
  larvae 
  of 
  B. 
  tomentosus. 
  In 
  the 
  same 
  way 
  

   the 
  fruits 
  which 
  were 
  protected 
  from 
  B. 
  tomentosus 
  by 
  spraying 
  with.. 
  

   Paris 
  green 
  were 
  also 
  able 
  to 
  develop 
  and 
  their 
  nectaries 
  showed 
  no 
  

   signs 
  of 
  injury. 
  Carbon 
  bisulphide 
  was 
  injected 
  into 
  the 
  soil 
  and 
  gave 
  

   excellent 
  results 
  in 
  spring, 
  but 
  less 
  favourable 
  in 
  autumn, 
  when 
  

   evidently 
  the 
  excessive 
  moisture 
  of 
  the 
  soil, 
  and 
  perhaps 
  also 
  the 
  cold, 
  

   decreased 
  the 
  effect 
  of 
  the 
  poison 
  ; 
  the 
  cost 
  of 
  this 
  remedy 
  is 
  about 
  

   Jd. 
  per 
  bush. 
  Wood 
  ashes 
  had 
  no 
  effect 
  on 
  the 
  beetles. 
  An 
  attempt- 
  

   to 
  drive 
  away 
  the 
  beetles 
  from 
  the 
  bushes 
  by 
  means 
  of 
  carbonic 
  acid, 
  

   carbon 
  bisulphide 
  and 
  tobacco 
  proved 
  quite 
  ineffective. 
  Shaking 
  the 
  

   beetles 
  into 
  specially 
  constructed 
  funnels 
  proved 
  a 
  useful 
  remedy 
  

   against 
  this 
  pest, 
  as 
  well 
  as 
  against 
  other 
  insects 
  which 
  may 
  attack 
  the 
  

   plants. 
  Spraying 
  with 
  Paris 
  green 
  is 
  not 
  recommended. 
  The 
  careful 
  

   and 
  timely 
  picking 
  of 
  the 
  ripe 
  raspberries, 
  accompanied 
  by 
  the 
  removal 
  

   of 
  the 
  damaged 
  ones, 
  is 
  considered 
  to 
  be 
  a 
  valuable 
  remedy 
  ; 
  the 
  

   collected 
  fruits 
  must 
  be 
  taken 
  away 
  from 
  the 
  gardens 
  at 
  once 
  so 
  as 
  to 
  

   prevent 
  the 
  larvae 
  from 
  getting 
  into 
  the 
  friable 
  soil 
  under 
  the 
  bushes 
  

   for 
  pupation, 
  which 
  is 
  the 
  most 
  favourable 
  ground 
  for 
  this 
  process. 
  

  

  Cydia

  L. 
  Owing 
  to 
  the 
  total 
  failure 
  of 
  the 
  

   apple 
  crops, 
  these 
  insects 
  oviposited 
  on 
  Crataegus 
  and 
  cherries 
  ; 
  in 
  

   many 
  places 
  the 
  damage 
  to 
  the 
  latter 
  was 
  very 
  noticeable. 
  The 
  

   caterpillars 
  of 
  Hyponomeuta 
  malinellics, 
  Z., 
  appeared 
  about 
  23rd 
  April 
  ; 
  

   pupation 
  took 
  place 
  from 
  the 
  6th 
  July. 
  An. 
  Ichneumonid 
  similar 
  to 
  

   Holocremnus 
  clandestinus, 
  Holmgr., 
  was 
  reared 
  from 
  the 
  pupae. 
  Early 
  

   in 
  spring 
  the 
  larvae 
  of 
  Argyresthia 
  ephippella, 
  F., 
  feed 
  on 
  buds 
  about 
  

   to 
  open 
  ; 
  the 
  leaves 
  and 
  blossoms 
  are 
  then 
  entangled 
  with 
  a 
  web, 
  

   the 
  larvae 
  feeding 
  on 
  the 
  young 
  leaves. 
  Later 
  they 
  eat 
  away 
  the 
  

   stamens, 
  stigmas, 
  styles 
  and 
  ovaries 
  of 
  the 
  blossoms. 
  Pupation 
  begins 
  

   in 
  the 
  middle 
  of 
  May, 
  the 
  imago 
  issuing 
  in 
  the 
  first 
  half 
  of 
  August. 
  

   The 
  eggs 
  were 
  found 
  on 
  cherry 
  leaves 
  in 
  groups, 
  covered 
  by 
  web. 
  

  

  Incurvaria 
  rubiella, 
  Bjerk. 
  On 
  16th 
  April, 
  12 
  bushes 
  of 
  raspberries 
  

   were 
  sprayed 
  with 
  the 
  following 
  mixtures, 
  about 
  2 
  lb. 
  of 
  caustic 
  Ume, 
  

   which 
  was 
  slaked 
  before 
  use, 
  and 
  1 
  oz. 
  of 
  Paris 
  green 
  in 
  4 
  J 
  gallons 
  of 
  

   water 
  ; 
  the 
  mixture 
  adhered 
  so 
  firmly 
  to 
  the 
  plant 
  that 
  the 
  rain 
  which 
  

   fell 
  the 
  next 
  day 
  could 
  not 
  wash 
  it 
  off. 
  The 
  results 
  of 
  the 
  spraying 
  

   were 
  very 
  satisfactory 
  and 
  only 
  one 
  bud 
  on 
  one 
  of 
  the 
  bushes 
  was 
  found 
  

   on 
  16th 
  May 
  to 
  be 
  infested 
  by 
  a 
  larva 
  of 
  this 
  moth, 
  while 
  on 
  some 
  bushes 
  

   left 
  purposely 
  unsprayed, 
  half 
  the 
  buds 
  contained 
  1 
  to 
  3 
  larvae. 
  A 
  

   parasitic 
  fly, 
  not 
  identified, 
  was 
  reared 
  from 
  one 
  pupa 
  ; 
  a 
  Chalcid 
  

   parasite 
  (Pteromalus) 
  was 
  also 
  obtained. 
  The 
  larvae 
  were 
  also 
  noticed 
  

   in 
  the 
  young 
  raspberries. 
  They 
  get 
  underneath 
  the 
  loose 
  bark 
  of 
  

   raspberry 
  bushes 
  near 
  the 
  bottom 
  of 
  the 
  stem, 
  not 
  higher 
  than 
  7 
  inches 
  

   from 
  the 
  ground, 
  and 
  there 
  they 
  build 
  cocoons 
  and 
  hibernate. 
  

  

  Zophodia 
  convolutella, 
  Hb. 
  It 
  has 
  been 
  observed 
  that 
  the 
  tiny 
  

   caterpillars 
  eat 
  into 
  the 
  fruits 
  of 
  gooseberry 
  and 
  currant, 
  and 
  only 
  the 
  

   change 
  in 
  colour 
  of 
  the 
  fruit, 
  which 
  turns 
  from 
  green 
  to 
  a 
  dark 
  or 
  red 
  

   colour, 
  indicates 
  the 
  presence 
  of 
  the 
  larvae. 
  In 
  the 
  autumn 
  of 
  1913, 
  

   fungus 
  disease 
  was 
  observed 
  on 
  the 
  larvae, 
  which 
  wintered 
  underneath 
  

   gooseberry 
  bushes.
