Abstract

Sperm transfer in the desert locust, Schistocerca gregaria (Forsk.), is accomplished by means of small (1.5 mm) spermatophores, formation of the first of which begins almost immediately after coupling. A normal copulation, which lasts 4 hours or longer, results in the production of about 6 spermatophores and a maximum of at least 14. Some details of the process of spermatophore formation are presented and differences among certain groups of acridoids are discussed.
