Flynn's questions are:

1. Are these (and other) species directly affected by the insecticide (which chemicals are used post-DDT?) and/or are mosquitoes ecologically important -- even keystone -- species?
2. What happens when you remove a parasite from the foodweb?

3. Our field crew is, among other things, cataloging the vegetation in the area -- could we expect to see e.g. fewer flowering plants?

4. Anything else we could look for?

4. Is anyone doing research on this quasi-Silent Spring phenomenon or know more about the possible ramifications of parasite/pest control?

Either these are good questions relevant to the mission of this list, and as such deserving of answers, or they are not. In the absence of such answers, or a polite reply that he should seek his answers elsewhere (an implied declaration that the questions are not relevant), what would be Flynn's reasonable conclusions with respect to the subscribers of this list?

we've noticed something interesting: there are no
mosquitoes in or near Alamosa. This is because the
city sprays for them regularly. We have also noticed
fewer grasshoppers, bees, and  frogs than we might
otherwise expect.

I don't know what chemical your county uses for mosquito
control but probably it is not specific to mosquitoes and
would affect other insects just as strongly.

Interesting these comments suggesting great harm to
both mosquitoes and non-target insects appeared just after
Mitch Cruzan said: "Critical thinking/reading is a primary goal
of all graduate programs and is something we introduce
undergraduates to in advanced courses."

A critical thinker would say it wildly speculative for anyone to
claim, without extensive direct evidence, that:

1) There really are no mosquitoes and fewer grasshoppers, bees,
and  frogs in Alamosa, Colorado.

2) Mosquito spraying is the underlying cause of these declines.
