Red Lilly Beetle

Identification

Now  the  warm  weather  here  and  our  lilies  are  starting  to  flower   or  at  least  start  growing  so  comes  one of  the  annoying  pest  to  the  gardener . The Red Lilly  beetle

Lily beetleIdentified  by  it  shiny  leather  red  back and  long  antenna these  are  the  most  voracious eaters  of  the  lily  plants    they  and  their larvae  can  strip  a  whole  plant  in  a  day

Lily Beetle Larvae

These horrible  things  is  what  the  larvae  looks  like. They  cover themselves  up  with  excreta  so  they  wont  get  any  predators  and  they  feast  on   the  leaves   until  they fall  to  the  ground  where  they  bury  themselves  in  the  ground  until  they  pupate

into  the  beetle  again  its  a  vicious  circle   they  can  grow  in  size  and  produce  multiple  generation

Control

Cultural Prevention

  • Since  the  larvae  live  in  the  earth   it’s  always  best  to  get  fresh   sterilized  soil   ie  peat  or  Coir  ( garden  earth  may  contain  the  larvae  at  least  starting  with  a  new  compost  and  pots  you  know  that  there  wont  be  a  chance  of  contamination  )

Cultural Control

  • Place  a white  paper  to towel on  the  compost  and  around  the plant
  •   pick  them  off  with  rubber  gloves.   But  their  young  are  well  camouflaged,  and  if  you should knock  them  off  then  they  have  a  cunning  way  of  laying  on  their  backs,  and  creeping  up  again  when  you  gone . hence  the  white  towel  which  make  them  easily  seen
  • then  when  your  sure  you  have  them  all  dispose  of  them  in  a  solution  of  soapy  water
  • another  trick  is  to  get  a  sticky  board   and  go  over  the  plant   this  should  catch  the  beetles  as  they  try to  take  flight    rather  like  the  white fly  traps

Organic  Approach

If  this  is  applied  dry  and  incorporated  into  the  soil   it  should   provide  a  good  barrier  against  anything  that  comes  across  it

Neem
kills larvae and repels adults. Neem is most effective on first instars
larvae; it must be applied every five to seven days after egg hatch. The
insecticide imidacloprid also provides effective control. It is
available in several formulations from Bayer including folia sprays,
soil drenches, and fertilizer stakes.”

  • Masking   the  scent

It  has  been  proved  that  they  are  attracted  by  the  smell  of  the  plant   so  though still  in  it  early  stage  of  development   this  and  introducing  the  parasitic wasp  might  be  way  forward
