My knowledge is mainly from observations of farmers experiments in India's
semi-arid tropics. I have seen farmers experimenting with different neem
based solutions targeting pod borer (helicoverpa). As far as I have seen,
there are no side effects on pest predators. Neem most definitely has no
harmful effects on human beings. Neem is an essential ingredient os many
home remedies in India, and is a used for dental care in much of rural
India (neem twigs, neem leaf paste etc).
There is a good reference that I remember but can't find the full
reference. Will send it soon. Meanwhile here are some more references.
