  thurberiae 
  on 
  Hibiscus 
  syriacus 
  it 
  was 
  found 
  that 
  it 
  was 
  quite 
  possible 
  

   for 
  the 
  insect 
  to 
  breed 
  in 
  the 
  buds, 
  and 
  it 
  seems 
  probable 
  that 
  this 
  

   would 
  not 
  be 
  unusual. 
  Louisiana 
  and 
  Texas 
  boU-weevils 
  and 
  the 
  

   Arizona 
  Thurberia 
  weevil 
  were 
  all 
  tested, 
  the 
  conduct 
  of 
  the 
  three 
  

   tjrpes 
  in 
  relation 
  to 
  feeding 
  being 
  practically 
  the 
  same 
  ; 
  all 
  showed 
  the 
  

   same 
  preference 
  for 
  feeding 
  first 
  on 
  the 
  corolla 
  and 
  the 
  stamens 
  of 
  the 
  

   flower, 
  followed 
  by 
  the 
  buds 
  and 
  then 
  the 
  fruit. 
  The 
  longevity 
  of 
  

   weevils 
  fed 
  on 
  Hibiscus 
  was 
  Httle 
  short 
  of 
  that 
  of 
  those 
  fed 
  on 
  cotton. 
  

   No 
  weevils 
  have 
  been 
  found 
  breeding 
  on 
  plants 
  other 
  than 
  cotton 
  and 
  

   Thurberia 
  under 
  field 
  conditions, 
  except 
  a 
  single 
  individual 
  on 
  Hibiscus 
  

   syriacus

  A 
  severe 
  outbreak 
  of 
  the 
  coconut 
  pest, 
  Brachartona 
  catoxantha, 
  has 
  

   occurred 
  in 
  the 
  coconut 
  plantations 
  about 
  the 
  head 
  of 
  the 
  Sirangoon 
  

   river, 
  near 
  Singapore. 
  These 
  caterpillars 
  also 
  attacked 
  the 
  leaves 
  of 
  a 
  

   species 
  of 
  Calamis 
  and 
  the 
  Areca 
  palm 
  in 
  the 
  affected 
  area. 
  The 
  

   degree 
  of 
  parasitism 
  of 
  the 
  pupae 
  due 
  to 
  a 
  Tachinid 
  and 
  a 
  Braconid 
  

   was 
  only 
  4 
  per 
  cent. 
  A 
  circular 
  was 
  distributed 
  among 
  the 
  plantation 
  

   owners 
  asking 
  them 
  to 
  bum 
  the 
  lower 
  leaves 
  of 
  the 
  palms 
  on 
  which 
  

   the 
  caterpillars 
  had 
  pupated 
  in 
  large 
  numbers. 
  By 
  this 
  means 
  and 
  by 
  

   spraying, 
  the 
  moths 
  were 
  kept 
  more 
  or 
  less 
  in 
  check, 
  but 
  it 
  was 
  evident 
  

   that 
  they 
  were 
  spreading 
  into 
  previously 
  unaffected 
  areas. 
  At 
  this 
  

   stage, 
  a 
  fungus, 
  new 
  to 
  science, 
  was 
  found 
  attacking 
  the 
  moth 
  and 
  

   with 
  its 
  aid 
  the 
  outbreak 
  was 
  stamped 
  out. 
  This 
  fungus, 
  which 
  has 
  

   been 
  named 
  Botrytis 
  necans, 
  was 
  distributed 
  artificially 
  by 
  taking 
  

   strips 
  of 
  coconut 
  leaves 
  with 
  dead 
  caterpillars 
  or 
  pupae 
  on 
  them 
  and 
  

   tying 
  them 
  to 
  the 
  leaves 
  of 
  trees 
  where 
  healthy 
  caterpillars 
  were 
  feeding 
  ; 
  

   the 
  caterpillar 
  pupates 
  in 
  a 
  silken 
  hammock 
  under 
  the 
  leaf 
  which 
  it 
  

   has 
  been 
  eating, 
  and 
  if 
  infected 
  by 
  the 
  fungus, 
  generally 
  dies 
  inside 
  

   the 
  hammock, 
  the 
  spores 
  coming 
  to 
  the 
  outside 
  in 
  the 
  form 
  of 
  dust 
  ; 
  

   the 
  fungus 
  is 
  therefore 
  easily 
  found, 
  and 
  there 
  was 
  no 
  difficulty 
  in 
  

   collecting 
  the 
  supphes 
  required 
  ; 
  the 
  distribution 
  of 
  the 
  fungus 
  was 
  

   probably 
  greatly 
  assisted 
  by 
  the 
  wind.

  A 
  systematic 
  account 
  is 
  given 
  of 
  the 
  Coccidae 
  of 
  Western 
  

   India, 
  which 
  are 
  not 
  well 
  known. 
  Although 
  Coccids 
  are 
  not 
  

   so 
  obvious 
  in 
  Western 
  India 
  as 
  in 
  some 
  other 
  parts, 
  they 
  occur 
  abun- 
  

   dantly 
  on 
  many 
  fruit 
  trees 
  ; 
  the 
  mango 
  tree 
  alone 
  is 
  attacked 
  by 
  many 
  

   species, 
  always 
  associated 
  with 
  the 
  Loranthus 
  (mistletoe) 
  parasite 
  ; 
  

   they 
  are 
  also 
  common 
  on 
  the 
  fruit 
  of 
  the 
  betelnut 
  palm 
  and 
  on 
  various 
  

   citrus 
  fruits. 
  Fruit 
  culture 
  is 
  now 
  increasing 
  and 
  the 
  importance 
  

   of 
  these 
  pests 
  will 
  be 
  more 
  fully 
  reaUsed 
  than 
  has 
  been 
  the 
  case 
  hitherto. 
  

   Fifteen 
  species 
  of 
  Diaspinae, 
  six 
  of 
  Lecaniinae, 
  four 
  of 
  Dactylopiinae, 
  

   one 
  of 
  Aster 
  olecaniinae, 
  and 
  two 
  of 
  Morwphlebinae 
  are 
  recorded.
