The Ecology and Behavior of Amphibians
Whatever initial advantage accrued to salamanders that produced
spermatophores, it is clear that the evolution of the spermatophore has had a
profound effect on the reproductive biology and social behavior of urodeles. One
consequence ...

Cricket Behavior and Neurobiology
Spennatophores All cricket males use spermatophores for insemination. For
depletion a spermatophore is either attached to the female's genitalia, or it is held
by the male and retained. In most species of Gryllinae a spermatophore consists
of ...

Cockroaches: Ecology, Behavior, and Natural History
In Periplaneta the spermatophore is not discharged until at least an hour from the
beginning of copulation (Gupta, 1947). In N. cinerea, where copulation length is
typically short, mating pairs detached after 10-12 min can be separated into ...

Reproductive Biology of Invertebrates, Accessory Sex Glands
The spermatophore of P. novaezealandidae is composed of: (a) an elongated
capsule containing the spermatozoa, embedded in a matrix; (b) a stalk
supporting the capsule; (c) accessory ampulla reminiscent of previous
connection between ...

Sperm Competition and Its Evolutionary Consequences in the ...
The ejaculate transfer hypothesis suggests that male postcopulatory associations
function in ensuring that the spermatophore remains attached long enough to
facilitate complete sperm transfer (Gerhardt 1913). In the crickets Gryllus ...

Ticks: A Monograph of the Ixodoidea
The ventral surface of the female is found bathed with coxal secretion, the
depression about the vulva has disappeared, and the collapsed spermatophore
is found attached to the vulva with its neck pushed into the vagina. The whole

of the seminal vesicle, the sperm and seminal fluid, partly mixing with them to
form the inner matrix of the spermatophore. The secretion from the lower parts of
the accessory glands forms the outer matrix, and, finally, the secretions from the ...

The Biology of Centipedes
This is supported by their observation that the glands are most active in
Cormocephalus when the centipede is courting and web spinning. The
spermatophore Fabre (1855) was the first worker to describe the spermatophore
of Scolopendra.

The Encyclopedia of Land Invertebrate Behaviour
Male centipedes lack an intromittent organ and rely on depositing a
spermatophore for the female to pick up. In the slender, soil- living
geophilomorph centipedes, the two sexes meet head to tail and tap one another
with their antennae and ...
