I have seen Sarracenia purpurea pitchers with the same symptoms in bogs
especially in the late summer and early fall. It seems like the pitchers
abort shortly after they begin to open. They don't appear to have any
insect infestations. At one time I did have a few of these plants growing
in the laboratory and occasionally had similar problems. I wonder if it
could be a fungal infection that penetrates the conductive tissues of the
pitchers or the rhizomes and prevents water flow? A spray-on fungicide
probably won't work for this. Some sort of systemic antifungal treatment
might be worth a try, although they can be pretty toxic to work with.
