  The 
  present 
  article 
  gives 
  the 
  two 
  principles 
  on 
  which 
  Lotrionte 
  

   based 
  his 
  system, 
  which 
  has 
  already 
  been 
  described 
  [see 
  this 
  Review 
  

   Ser. 
  A, 
  ii, 
  pp. 
  289 
  and 
  452]. 
  (1) 
  A 
  solution 
  of 
  glucose 
  is 
  more 
  

   attractive 
  to 
  the 
  fly 
  than 
  one 
  containing 
  molasses; 
  (2) 
  a 
  1 
  per 
  cent, 
  

   copper 
  sulphate 
  solution 
  is 
  more 
  deadly 
  to 
  the 
  fly 
  than 
  one 
  of 
  

   either 
  sodium 
  or 
  potassium 
  arsenite. 
  Other 
  workers 
  used 
  these 
  

   latter 
  poisons, 
  with 
  molasses 
  as 
  the 
  bait, 
  and 
  attained 
  but 
  little 
  success 
  

   (but 
  see 
  references 
  above). 
  The 
  " 
  capannette 
  " 
  or 
  covers 
  peculiar 
  to 
  

   this 
  system 
  also 
  permit 
  expenses 
  to 
  be 
  cut 
  down 
  to 
  a 
  minimum.

  In 
  this 
  report 
  the 
  author 
  describes 
  the 
  division 
  of 
  the 
  Selangor 
  State 
  

   for 
  this 
  purpose 
  and 
  the 
  methods 
  followed. 
  From 
  early 
  in 
  January 
  the 
  

   flying 
  sw^arms 
  were 
  kept 
  under 
  observation, 
  in 
  order 
  that 
  oviposition 
  

   centres 
  might 
  be 
  known. 
  Later 
  in 
  the 
  month, 
  large 
  numbers 
  of 
  gravid 
  

   females 
  were 
  destroyed 
  by 
  shaking 
  them 
  off 
  bushes 
  and 
  trees 
  at 
  night 
  

   into 
  sacking 
  spread 
  below. 
  The 
  insects 
  were 
  known 
  to 
  have 
  finished 
  

   egg-laying 
  by 
  January 
  30th. 
  The 
  first 
  batches 
  were 
  found 
  on 
  Januar}^ 
  

   22nd. 
  The 
  larvae 
  began 
  hatching 
  on 
  Februar}^ 
  1st, 
  and 
  on 
  February 
  

   13th 
  and 
  23rd, 
  in 
  the 
  north 
  and 
  south 
  parts 
  of 
  the 
  State 
  respectively, 
  

   destruction 
  was 
  begun. 
  In 
  the 
  northern 
  part, 
  by 
  March 
  12th, 
  the 
  

   locusts 
  were 
  considerably 
  reduced, 
  about 
  16 
  large 
  swarms 
  having 
  

   been 
  dealt 
  with, 
  and 
  it 
  is 
  hoped 
  that 
  the 
  danger 
  of 
  locusts 
  spreading 
  

   into 
  Perak 
  is 
  now 
  over, 
  though 
  unknown 
  jungle 
  swarms 
  may 
  give 
  

   trouble. 
  Similar 
  efforts 
  were 
  made 
  in 
  South 
  Selangor 
  and 
  the 
  total 
  

   catch 
  in 
  the 
  State 
  between 
  February 
  13th 
  and 
  March 
  15th 
  was 
  3,314 
  

   tins, 
  representing 
  about 
  65 
  swarms. 
  Similar 
  results 
  w^ere 
  obtained 
  in 
  

   Negri 
  Sembilan. 
  The 
  author 
  expects 
  that 
  by 
  the 
  end 
  of 
  six 
  months 
  

   these 
  States 
  will 
  be 
  approximately 
  free 
  from 
  locusts, 
  and 
  that 
  any 
  

   swarms 
  left 
  will 
  be 
  small 
  and 
  scattered.
