“…Finally, whatever role the secretions of the oviducts execute during the reproductive process in E. betulae, the transit of an egg and its interaction with male gametes also occur by means of the rhythmic contractions of the muscle fibres of these organs; it is known, in fact, that these contractions increase before or after the mating, in response to nerve stimulations (Cook et al 1980;Lange et al 1984) or hormonal factors (Lange 1987).…”

The ultrastructure of the genital tracts in amphigonic females of Aphidoidea is described for the first time, using Euceraphis betulae Koch (Aphididae: Calaphidinae) as a representative. The female reproductive apparatus consists of two ovaries, each one with three/four meroistic telotrophic ovarioles; two sac‐like accessory glands lie laterally to a sac‐like seminal receptacle, opening into the dorso‐medial part of the common oviduct by means of a spermathecal duct. A marked secretory activity takes place in the epithelial cells of all the investigated tracts as shown by ultrastructural observation of many organelles involved in this process. No evident golgian area was observed in the cytoplasm of these cells. Extensive smooth endoplasmic reticulum, whose probable role is here discussed, was observed in epithelial cells of the wall of the accessory gland. Spermathecal duct and seminal receptacle had peculiar features that could be related to different secretory activities carried out by these two parts of the spermatheca.

“…with bandpass filters set at 300 Hz and 1 KHz for nervous activity and 0.1 Hz and 1 KHz for muscular activity. Extracellular recordings of this type from insect visceral muscle have previously been shown to record potentials of the same polarity as those observed from intracellular recordings [eg, 11,161. The signals were displayed on a Tektronix storage oscilloscope and concurrently taped on a Vetter FM recorder for subsequent playback and analysis.…”

The oviducts of Locusta migratoria are innervated by a pair of nerves which arise from the seventh abdominal ganglion. A distinctive network of striated muscle fibres occurs in the oviducts. The lateral oviducts and common oviduct consist of an inner circular layer of muscle and an outer longitudinal layer of muscle. At the junction of the lateral and common oviduct an additional thin longitudinal layer is found adjacent to the basement epithelium.The oviducts contracted spontaneously when isolated from the central nervous system. These myogenic contractions took the form of peristaltic contractions in the lateral oviduct, and intermittent phasic-like contractions of the posterior regions of the lateral oviduct and the common oviduct. These phasic-like contractions were associated with individual complex potentials recorded extracellularly from the muscle fibres.In locusts that had been interrupted in the process of egg laying, there were large-amplitude action potentials, firing in a bursting pattern, in the oviducal nerves. These large action potentials were absent in locusts that had not been egg-laying. These action potentials were associated with both bioelectric potentials and mechanical events in the posterior region of the lateral oviduct and the common oviduct.Electrical stimulation of the oviducal nerve mimicked the effects of spontaneous action potentials, resulting in the appearance of monophasic potentials and contractions. The contractions were graded and dependent upon both frequency and duration of stimulation.It i s concluded that the oviducts of Locusta are both myogenic and neurogenic. The role of these contractions in oviposition is discussed.

“…The ovarian muscularis, like the visceral muscles in most insects, shows a spontaneous and rhythmic pattern of contractions both in vivo and in vitro. Although brief descriptions of such events have been reported for Rhodnius prolixus [l], Tabanus sulcifrons [2], Aedes aegypti [3], and the pink bollworm moth, Pectinophora gossypielZa [4], no attempts have yet been made to describe the basic types of motility for this kind of activity in any insect.…”
