Are there toxicological references on neem? If it has pesticidal
properties (or repellant, at least?), I'd like to know it was fairly
specific to the target species and didn't have broader effects on other
ecosystem elements (like beneficial insects) or humans.

Bob,
Thanks to Jayne MacLean, former Coordinator of the Alternative Farming
Systems Information Center (AFSIC), now an occasional volunteer in our
office, for doing a cursory literature review on the effects of neem on
nontarget species.
Here's some of what she found:
AU: Kreutzweiser,-D.P.
TI: Nontarget effects of neem-based insecticides on aquatic
invertebrates.
SO: Ecotoxicol-environ-saf. Orlando, Fla. : Academic Press. Mar 1997. v.
36 (2) p. 109-117.
CN: DNAL QH545.A1E29
LA: English
FROM the conclusions(this experiment was on forest use of neem), I quote:
"These experiments indicated there is little risk of direct adverse effects
on aquatic macroinvertebrates resulting from contamination of water bodies
with neem-based insecticides used in forest pest management applications."
A few other comments from Jayne's search:
a) She found no references to the use of neem against mosquitoes;
b) neem is almost entirely non-toxic to warm-blooded organisms, including
humans.
