Parasites can influence various aspects of host reproduction and mating, including spermatophore production. In the cricket, Gryllodes sigillatus, males transfer to females a two-part spermatophore containing a sperm-filled ampulla and a gelatinous spermatophylax (nuptial gift). Here we investigate the effects of a sexually transmitted nematode on male spermatophylax production. Sexually transmitted diseases (STDs) have the potential to reduce host fertility or fecundity in insect hosts. To our knowledge this is the first empirical study on the effects of an insect STD on the reproductive physiology of a male host. Our results indicate that infected males produc...
