  The 
  author 
  had 
  hoped 
  to 
  be 
  able 
  to 
  breed 
  froghoppers 
  during 
  the 
  

   dry 
  season, 
  on 
  a 
  suitable 
  scale 
  as 
  food 
  for 
  Syrphids, 
  in 
  a 
  specially 
  

   constructed 
  cage 
  in 
  which 
  sugar-cane 
  was 
  planted, 
  but 
  this 
  has 
  not 
  

   been 
  realised. 
  The 
  cane 
  showed 
  no 
  signs 
  of 
  froghopper 
  attack 
  and 
  

   apparently, 
  in 
  spite 
  of 
  artificial 
  watering, 
  the 
  froghopper 
  eggs 
  do 
  not 
  

   hatch. 
  The 
  following 
  conditions, 
  the 
  author 
  says, 
  are 
  unfavourable 
  to 
  

   incubation 
  : 
  low 
  temperature 
  at 
  nights, 
  dry 
  atmosphere, 
  and 
  lack 
  of 
  

   heated 
  moisture 
  in 
  the 
  soil. 
  

  

  The 
  attention 
  of 
  planters 
  is 
  drawn 
  to 
  the 
  following 
  instructions. 
  

   After 
  the 
  first 
  appearance 
  of 
  early 
  broods 
  of 
  froghopper 
  nymphs 
  

   they 
  should 
  be 
  destroyed 
  by 
  hand-picking 
  ; 
  the 
  early 
  adult 
  broods 
  

   should 
  be 
  destroyed 
  with 
  kerosene-lysol 
  emulsion 
  or 
  by 
  squeezing 
  

   the 
  leaf-sheaths.

  The 
  author 
  describes 
  the 
  damage 
  done 
  by 
  the 
  larvae 
  of 
  A. 
  pomorum 
  

   to 
  the 
  buds 
  of

  trees 
  and 
  proceeds 
  to 
  consider 
  the 
  remedies 
  

   usually 
  recommended. 
  He 
  thinks 
  that 
  sticky 
  bands 
  cannot 
  prevent 
  

   the 
  females 
  from 
  reaching 
  the 
  fruit 
  buds 
  and 
  ovipositing 
  on 
  them, 
  

   although 
  this 
  remedy 
  decreases 
  to 
  some 
  extent 
  the 
  damage 
  done 
  by 
  

   the 
  pests, 
  especially 
  when 
  the 
  belts 
  are 
  inspected 
  daily 
  and 
  the 
  females 
  

   beneath 
  them 
  destroyed. 
  Spraying

  cannot, 
  in 
  the 
  opinion 
  of 
  the 
  author, 
  protect 
  

   every 
  bud 
  from 
  the 
  weevils, 
  and 
  it 
  is 
  not 
  clear 
  to 
  him 
  w^hat 
  the 
  effect 
  

   of 
  this 
  remedy 
  is 
  : 
  whether 
  it 
  prevents 
  oviposition 
  mechanically 
  or 
  

   poisons 
  the 
  females 
  or 
  larvae. 
  The 
  collection 
  of 
  the 
  damaged 
  buds 
  

   in 
  May, 
  recommended 
  by 
  Mokrzecki, 
  is 
  expensive 
  and 
  also 
  seems 
  to 
  

   be 
  too 
  long 
  delayed, 
  as 
  most 
  of 
  the 
  larvae 
  have 
  at 
  this 
  time 
  already 
  

   completed 
  their 
  development

  The 
  author 
  says 
  that 
  in 
  the 
  State 
  of 
  Mississippi 
  insect 
  and 
  fungus- 
  

   pests 
  are 
  present 
  everywhere 
  and 
  greatly 
  favoured 
  by 
  the 
  climate. 
  

   The 
  San 
  Jose 
  scale 
  is 
  generally 
  distributed 
  and 
  control 
  measures 
  are 
  

   only 
  partially 
  successful, 
  annual 
  spraying 
  being 
  necessary 
  in 
  orchards. 
  

   Ourculionids 
  are 
  very 
  destructive 
  and, 
  unless 
  energetic 
  measures 
  be 
  

   taken, 
  may 
  be 
  expected 
  to 
  ruin 
  entire 
  orchards. 
  The 
  cultivation 
  of 
  

   fruit 
  has 
  hitherto 
  been 
  discouraging, 
  and 
  apples 
  became 
  infested 
  with 
  

   vSan 
  Jose 
  scale 
  from 
  an 
  orchard 
  two 
  miles 
  away. 
  Spraying 
  was 
  carried 
  

   on 
  vigorously 
  in 
  dry 
  weather, 
  but 
  constantly 
  recurring 
  rains 
  washed 
  

   off 
  the 
  mixture 
  and 
  the 
  trees 
  were 
  killed 
  outright 
  by 
  scale, 
  nematodes 
  

   and 
  borers. 
  A 
  commercial 
  orchard 
  of 
  500 
  plum 
  trees 
  had 
  to 
  be 
  

   destroyed 
  owing 
  to 
  the 
  attacks 
  of 
  Curculio 
  (Conotrachelus 
  nenuphar). 
  

   Pears 
  seem 
  to 
  have 
  fewer 
  enemies 
  than 
  peaches 
  and 
  plums. 
  Individual 
  

   fig 
  trees 
  do 
  well 
  when 
  the 
  soil 
  is 
  packed 
  hard, 
  but 
  under 
  orchard 
  

   conditions, 
  when 
  the 
  soil 
  is 
  kept 
  clean 
  and 
  loose, 
  the 
  roots 
  are
