Reproductive Biology of Invertebrates, Accessory Sex Glands
Aedes aegypti, however, a few glandular cells like those of the spermatheca
occur in the upper part of the spermathecal duct (Clements and Potter, 1967;
Jones and Fischman, 1970). And in Melanoplus sanguinipes, the histology of the
duct is ...

Insect Ecology: An Ecosystem Approach
he spermatheca is a special pouch in the female in which spermatozoa are
stored and maintained after mating. In more advanced insects, the male deposits
seminal fluid or a spermatophore into the bursa copulatrix, and the sperm then
move ...

Female Control: Sexual Selection by Cryptic Female Choice
about one-third that of the spermatheca, and the ejaculate fills this sac (see fig.
2.9). Males obviously have more sperm available, as they often copulate up to
four times with the same female in the space of only two hours. Female behavior

The Insects: Structure and Function
Transfer of sperm to the spermatheca. Immediately following the transfer of the
spermatophore, the sperm migrate to the spermatheca, where they are stored.
Sometimes they are able to escape from the sperm sac through a pore, but in
other ...

Sperm Competition and Its Evolutionary Consequences in the ...
Sperm flow from the spermatophore in the bursa copulatrix along the length of
the flagellum and into the spermatheca. Thus, the flagellum in this species plays
an important role in the transportation of sperm to the sperm storage organ.

Cockroaches: Ecology, Behavior, and Natural History
In Crypto- cercus the spermatheca is forked, with the branches terminally
expanded; the single spermathecal opening lies in the roof of the genital
chamber. The spermatheca of Lamproblatta has a wide, sclerotized basal portion
and a slender ...

Blackflies (Simuliidae) [Moshki (sem. Simuliidae)]
In adults the location of groups of enocytes is quite constant: near the salivary
glands, commencement of midgut, in the testes and ovaries, near the
spermatheca, around the genital cavity (in which the spermatophore of the male
is retained), ...

Advances in Insect Physiology
Accordingly, it has been noted in several cases that apyrene sperm arrive at the
spermatheca earlier than their eupyrene counterparts (C. pomonella, White et al.,
