HELP!!! Pitaya / Cerus / Dragon fruit rotting
I have had a Pitaya / Cerus / Dragon Fruit for a few years now and have never gotten fruit from it since it always rots within a week or so after bloom. It appears that there are some sort of small beetles going into the flower the night of bloom and laying larvae which then destroy the bud before it can develop and the immature fruit drops. I have included a link to pictures if anyone can tell me what it looks like and offer suggestions. I have thought of the obvious, spray with insecticide but I would have to spray inside the flower which will become the fruit I wish to eat...not sounding like a good plan! THANKS for any help!!!
