  The 
  squash 
  bug 
  winters 
  in 
  the 
  adult 
  stage 
  under 
  rubbish 
  and 
  among 
  

   old 
  vines. 
  Clean 
  culture 
  is 
  therefore 
  an 
  important 
  remedial 
  measure. 
  

   Insects 
  in 
  stored 
  products, 
  such 
  as 
  the 
  grain 
  weevil, 
  pea 
  weevils, 
  flour 
  

   moths, 
  etc., 
  are 
  best 
  checked 
  by 
  fumigation 
  with 
  carbon 
  bisulphide. 
  

   An 
  air-tight 
  fumigating 
  room 
  is 
  an 
  essential. 
  Pour 
  the 
  carbon 
  

   bisulphide 
  into 
  shallow 
  dishes 
  and 
  place 
  in 
  the 
  bins, 
  using 
  5 
  lb. 
  to 
  1,000 
  

   cubic 
  feet 
  of 
  space. 
  The 
  temperature 
  should 
  be 
  70° 
  Fahr. 
  or 
  above 
  for 
  

   the 
  best 
  results. 
  Insects 
  in 
  greenhouses, 
  such 
  as 
  red 
  spiders 
  and 
  mealy 
  

   bugs, 
  are 
  best 
  checked 
  by 
  syringing 
  the 
  plants 
  forcibly 
  with 
  water 
  two 
  

   or 
  three 
  times 
  a 
  day. 
  The 
  caterpillars 
  of 
  the 
  California 
  tussock 
  moth 
  

   feed 
  upon 
  young 
  fruit 
  and 
  foliage. 
  This 
  pest 
  spends 
  the 
  winter 
  in 
  the 
  

   egg 
  stage, 
  the 
  eggs 
  being 
  in 
  masses 
  attached 
  to 
  the 
  trunks 
  of 
  trees 
  and 
  

   adjacent 
  objects 
  ; 
  the 
  hand-picking 
  of 
  egg-masses 
  will 
  greatly 
  reduce 
  

   their 
  numbers.

  A 
  short 
  account 
  is 
  given 
  of 
  pests 
  of 
  stored 
  grain 
  in 
  Nyasaland, 
  the 
  

   two 
  chief 
  of 
  which 
  are 
  the 
  Grain 
  Moth 
  [Sitotroga 
  cerealella, 
  01.), 
  and 
  the 
  

   Rice 
  Weevil 
  {Calandra 
  oryzae, 
  L.). 
  With 
  these 
  is 
  often 
  found 
  another 
  

   beetle, 
  Triboliiim 
  confusum, 
  Duv., 
  which, 
  however, 
  does 
  no 
  serious 
  

   damage. 
  Fumigating 
  with 
  carbon 
  bisulphide 
  is 
  recommended.

  The 
  dreaded 
  Colorado 
  beetle 
  and 
  a 
  few 
  other 
  pests 
  prevalent 
  in 
  

   America 
  and 
  elsewhere 
  are 
  absent 
  from 
  Australia, 
  and 
  with 
  the 
  careful 
  

   inspection 
  and 
  quarantine 
  in 
  Melbourne 
  of 
  all 
  potatoes 
  arriving 
  from 
  

   abroad, 
  growers 
  have 
  httle 
  fear 
  of 
  new 
  pests 
  being 
  introduced. 
  The 
  

   Potato 
  Thrips, 
  Thrips 
  tabaci, 
  Lind., 
  has 
  caused 
  considerable 
  losses, 
  

   and 
  appears 
  to 
  be 
  on 
  the 
  increase. 
  They 
  attack 
  plants 
  of 
  all 
  kinds. 
  

   If 
  debris 
  is 
  examined 
  during 
  the 
  winter, 
  they 
  are 
  found 
  in 
  great 
  

   numbers 
  ; 
  the 
  first 
  warm 
  days 
  of 
  October 
  brings 
  them 
  out 
  in 
  thousands, 
  

   and 
  on 
  the 
  underside 
  of 
  the 
  potato 
  leaves 
  they 
  will 
  be 
  found 
  in 
  varying 
  

   stages 
  of 
  development. 
  Total 
  development 
  occupies 
  10-15 
  days 
  in 
  

   Victoria. 
  The 
  thrips 
  pest 
  is 
  a 
  serious 
  one, 
  and 
  unless 
  definite 
  measures 
  

   are 
  taken 
  against 
  it, 
  it 
  will 
  be 
  impossible 
  to 
  grow 
  good 
  crops 
  ; 
  the 
  

   lower 
  leaves 
  of 
  the 
  plant 
  are 
  attacked 
  first 
  and 
  as 
  these 
  are 
  destroyed 
  

   the 
  top 
  ones 
  are 
  affected 
  in 
  turn. 
  All 
  debris 
  on 
  potato 
  fields 
  should 
  be 
  

   destroyed; 
  by 
  this 
  means 
  hibernating 
  insects 
  and 
  their 
  eggs 
  will 
  be
