Fine structure of the regional differentiation of the ductus ejaculatorius simplex (EJ1, EJ2, EJ3) along with the role of their secretions in sperm activation and motility in two Noctuid species,Heliothis armigera (Hübner) andSpodoptera litura (Fabricius) (Lepidoptera). II. Fine structure and function of simplex 2 (EJ2)

Characteristics of the Male Reproductive System and Spermatozoa of Leptophlebiidae (Ephemeroptera)

“…brieni) and of degenerative vesicles inside these cell fragments seem to con irm this hypothesis. Some studies have reported the presence of holocrine and apocrine secretion in the ducts of male reproductive systems of different insects (Leopold 1970, Perotti 1971, Riemann 1973, Almadoss 1990, Brito et al 2010.…”

16. Reproductive organs

“…An early comparative histological study of the male system treating several ditrysian micromoths is Stitz (1901). Subsequent gross-morphological and/or cytological accounts deal with exemplars of, e. g., the Micropterigidae (Pyatin & Stekolnikov 2001), Agathiphagidae (Kristensen 1984), Eriocraniidae (Davis 1978, Pyatin & Stekolnikov 2001), Lophocoronidae (Nielsen & Kristensen 1996), Hepialidae (Nielsen & Kristensen 1989), Adelidae (Pyatin & Stekolnikov 2001), Tischeriidae (Knaben 1931), Plutellidae (Thibout 1971), Gelechiidae (Brits 1978), Zygaenidae (Fänger & Naumann 1993), Tortricidae (Outram 1970), Pyraloidea (Chaudhury & Raun 1966, Jones et al 1984; important ultrastructural accounts by Riemann & Thorson 1976a, b, 1979, Hesperiidae (important ultrastructural accounts by Lai-Fook 1982 a-e), Sphingidae (Reinecke et al 1983), Noctuidae (Outram & Campion 1967, Holt & North 1970, Amaldoss 1989a, b, 1990a, b, Amaldoss & Shang 1989; sperm research has an extensive literature of its own (see below). Morphogenetic studies treatments treat exemplars of, e. g., Psychidae (Florin (1945), Pyralidae (Jones et al 1984) and Sphingidae (Reinecke et al 1983).…”
