  the

  An 
  attempt 
  to 
  introduce 
  Novius 
  cardinalis 
  

   into 
  Mauritius 
  from 
  South 
  Africa 
  failed, 
  but 
  it 
  is 
  hoped 
  that 
  Icerya 
  

   seychellarum, 
  which 
  attacks 
  roses 
  and 
  other 
  ornamental 
  plants, 
  will 
  

   be 
  checked 
  by 
  this 
  CoccineUid 
  once 
  it 
  is 
  estabhshed. 
  Pseudococcus 
  

   (Coccus) 
  indicus 
  and 
  Pseudococcus 
  (C.) 
  ca^pensis 
  will 
  shortly 
  be 
  

   available 
  for 
  distribution, 
  and 
  it 
  is 
  hoped 
  that 
  these 
  insects 
  will 
  be 
  

   as 
  effective 
  against 
  the 
  prickly 
  pear, 
  Opuntia 
  monacaniha, 
  as 
  they 
  

   have 
  proved 
  in 
  experiments 
  in 
  South 
  Africa. 
  An 
  unsuccessful 
  attempt 
  

   was 
  also 
  made 
  to 
  introduce 
  a 
  Hymenopterous 
  parasite 
  of 
  Sesamia 
  

   vuteria 
  (nonagrioides) 
  from 
  South 
  Africa.

  As 
  in 
  previous 
  years 
  [see 
  this 
  Review, 
  Ser. 
  A, 
  i, 
  pp. 
  28-31] 
  the 
  

   Dynastid 
  beetle 
  Oryctes 
  tarandus 
  was 
  prevalent 
  during 
  1913 
  on 
  

   certain 
  sugar 
  estates, 
  but 
  the 
  method 
  of 
  digging 
  out 
  the 
  larvae 
  was 
  

   adopted 
  more 
  widely 
  and 
  has 
  proved 
  to 
  be 
  highly 
  beneficial. 
  The 
  

   Melolonthid 
  Lachnosterna 
  sp. 
  was 
  found 
  on 
  sugar-cane 
  in 
  small 
  

   numbers, 
  control 
  measures 
  being 
  responsible 
  for 
  a 
  noticeable 
  

   reduction. 
  Aphis 
  sacchari 
  occurred 
  in 
  great 
  numbers 
  on 
  two 
  sugar 
  

   estates, 
  but 
  by 
  the 
  middle 
  of 
  July 
  all 
  the 
  insects 
  were 
  destroyed 
  

   by 
  a 
  fungus. 
  The 
  white 
  borer, 
  the 
  larva 
  of 
  a 
  small, 
  greyish 
  moth, 
  

   not 
  yet 
  determined, 
  was 
  very 
  abundant 
  throughout 
  the 
  island 
  

   in 
  virgin 
  canes, 
  while 
  burning 
  previous 
  to 
  cropping 
  was 
  suggested 
  in 
  

   order 
  to 
  protect 
  the 
  rattoons 
  and 
  to 
  avoid 
  the 
  dissemination 
  of 
  Chion- 
  

   aspis 
  tegalensis. 
  A 
  census 
  of 
  the 
  area 
  infected 
  by 
  Phytalus 
  smithiy 
  

   Arrow, 
  made 
  in 
  May 
  and 
  June 
  1913, 
  indicated 
  that 
  this 
  pest 
  was 
  not 
  

   spreading. 
  During 
  1913 
  some 
  34 
  million 
  insects 
  were 
  destroyed, 
  

   against 
  15 
  million 
  in 
  1912 
  and 
  24 
  miUion 
  in 
  1911. 
  The 
  increase 
  of 
  

   captures 
  in 
  1913 
  was 
  probably 
  due 
  to 
  the 
  reward 
  offered 
  being 
  higher 
  

   than 
  in 
  1912, 
  and 
  secondly, 
  to 
  a 
  more 
  thorough 
  knowledge 
  of 
  the 
  

   habits 
  of 
  the 
  beetle. 
  Up 
  to 
  the 
  end 
  of 
  December 
  1913, 
  some 
  adults, 
  

   chiefly 
  males, 
  of 
  Tiphia 
  parallela, 
  Smith, 
  had 
  been 
  observed 
  in 
  the 
  

   insectary 
  built 
  for 
  the 
  breeding 
  of 
  this 
  Scoliid 
  parasite 
  of 
  P. 
  smithi. 
  

   Other 
  insects 
  damaging 
  various 
  crops 
  were 
  Ceratitis 
  capitatGy 
  Dacus 
  

   ferrugineus, 
  Agromyza 
  phaseoli, 
  Prodenia 
  littoralis, 
  lawn 
  cutworm 
  

   (Crambus 
  sp.), 
  Cratopus 
  punctum, 
  Adoretus 
  versutus, 
  Sphenophorus 
  

   s^na^ws 
  (banana 
  borer), 
  and 
  Coccus 
  viridis 
  (Lecanium 
  viride),heaidea 
  

   numbers 
  of 
  other 
  mealy 
  bugs 
  and 
  scale-insects. 
  Tomatoes 
  were 
  seriously 
  

   damaged 
  by 
  the 
  eelworm, 
  Heterodera 
  radicicola. 
  The 
  * 
  ' 
  lawn 
  cutworm, 
  ' 
  ' 
  

   which 
  for 
  the 
  last 
  few 
  years 
  has 
  been 
  a 
  serious 
  pest, 
  was 
  successfully 
  con- 
  

   trolled 
  by 
  means 
  of 
  an 
  application 
  of 
  kerosene 
  mixture 
  made 
  as 
  follows 
  :: 
  

   1 
  part 
  (by 
  weight) 
  of 
  common 
  soap 
  is 
  dissolved 
  in 
  20 
  parts 
  of 
  water, 
  

   40 
  parts 
  petroleum 
  being 
  gradually 
  added 
  ; 
  to 
  24 
  parts 
  of 
  this 
  emulsion 
  

   add 
  16 
  parts 
  Phenyl 
  or 
  12 
  parts 
  Creohne. 
  A 
  2 
  per 
  cent, 
  solution 
  of 
  

   this 
  mixture 
  does 
  not 
  injure 
  grass 
  if 
  apphed 
  at 
  the 
  rate 
  of 
  11 
  gallons 
  

   per 
  80 
  square 
  feet 
  for 
  the 
  destruction 
  of 
  subterranean 
  caterpillars 
  and 
  

   Oryctes 
  larvae.
