It does. Look it up.

Perhaps you can point me in the right direction? I've seen what looks like
guesses that ivermectin might have adulticidal action, but nothing that
looks scientific.

Thanks :-).

I've got to run, so, from a discussion between buglady and me a while
ago:

buglady:
.................Ivermectin does have some effect on the adults. I think
there was a study done a few years ago.

me:
Yes, by John McCall. He found that " lengthy course of prophylactic
doses of ivermectin will gradually reduce the number of adult
heartworms, but in chronic mature infections this may not be as
clinically beneficial"(from a presentation by Dr. McCall given at the
2004 American Heartworm Society Symposium). I saw something on a
website stating that McCall found higher than prophylactic doses to be
no more effective in killing adult heartworms, but I couldn't find any
verification of that. I don't recall the average life expectancy of a
heartworm; do you know?

In cats it's 2 years and dogs about 5 years with no treatments of anykind.

I see that Shadow Walker says five years. My vet told me three years, in
response to my question about a dog in rescue that was HW positive.

I have noted a lot of people are having problems finding information on
heartworms. Here are some links.

I wasn't actually asking the question here; it was a quote from an old
post to Buglady. Her answer, as I recall was that some say 3 years,
some say 5, but they don't really know for sure.
