Abstract

Ammonia is known to be a repellent gas for rising sorogens of , and it has been suggested that it is also a repellent gas for migrating slugs of the same species. Here we present evidence that migrating slugs of and two related species, and , indeed orient away from high concentrations of NH. In , brief exposure of a slug to an NH gradient of about 1 p.p.m. mm (10 atm cm or 0·00076 mmHg mm) was sufficient to alter the direction of its migration. The gases of other weak bases, such as methylamine, trimethylamine, ethylamine and pyrrolidine, were also effective.
