Nitrobenzene reduction and reductive cleavage of azobenzenes in two species of Arachnida

The metabolism of [¹⁴C]-nitrobenzene and [¹⁴C]-4-dimethyl-aminoazobenzene was examined in a tick, $\text{Boophilus microplus}$, and a spider, $\text{Nephila plumipes}$. The reduction of both compounds to aniline is reported in both species. N-Dealkylation of DAB is also recorded.
