Mating- and oviposition-dependent changes of the spermatheca and colleterial glands in the pest termite Cryptotermes brevis (Blattaria, Isoptera, Kalotermitidae)
The spermatheca and colleterial glands of female insects are organs associated with the reproductive system, responsible for sperm storage and...

Morphology of testis, sperm, and spermatheca in two capable hybridized termite species indicates no interspecific reproductive isolation
It would not surprise that two related termite species are similar in many traits, especially those related to reproduction such as similarity in...

Ultrasturucture of Aedeagus and Spermatheca of type species of Hypocassida Weise, 1893 (Chrysomelidae: Cassidinae: Cassidini) and their taxonomic significance
Aedeagus and spermatheca of the type species Hypocassida subferruginea (Schrank) of the Palaearcticgenus Hypocassida Weise have been studied and...

Comprehensive dynamic analysis of proteins in the spermatheca of female Haemaphysalis longicornis after copulation
Ticks are obligate blood-sucking parasitic arthropods. When sucking the blood of hosts, they can also transmit a variety of pathogens to hosts that...

Spermatheca of the scorpionfly Sinopanorpa tincta (Navás, 1931) (Mecoptera: Panorpidae)
The spermathecal structure of the scorpionfly Sinopanorpa tincta (Navás, 1931) was investigated using light microscopy, scanning, and transmission...

Caste differentiation of spermatheca and organs related to sperm use and oviposition in the honeybee, Apis mellifera
Striking queen–worker dimorphism associated with each task is a key feature of highly eusocial insects, including Apis mellifera . The present study...

Transition in the production of diploid-female to haploid-male eggs in bumblebee colonies: sperm quality or depletion?
AbstractBumblebees establish annual colonies that start with the emergence of workers in spring and end with the production of sexuals, the majority...

Effects of simulated tropical heat waves during development on the morphological and reproductive traits of Africanized honey bee
Global warming may have a significant negative impact on insects in the tropics due to an increase in the frequency and intensity of heat waves. Heat...

Setting the records straight II: “single spermatheca” of Braula coeca (Diptera: Braulidae) is really the ventral receptacle
Braula coeca has been reported repeatedly, but incorrectly, to have only a single spermatheca—an extremely rare condition in the higher flies. This...

The mechanoreceptor Piezo is required for spermatogenesis in Bombyx mori
BackgroundThe animal sperm shows high diversity in morphology, components, and motility. In the lepidopteran model insect, the silkworm Bombyx mori ,...

Mating behaviors and multiple mating in the firebrat, Thermobia domestica (Zygentoma: Lepismatidae)
While most terrestrial animals undergo internal fertilization, some insects use external transfer of sperm during mating. Among these are insects...

Male-female communication enhances release of extracellular vesicles leading to high fertility in Drosophila
The female reproductive tract (female-RT) must decipher the repertoire of molecular cues received from the male during copulation in order to...

Notes on the biology of Protanilla sp. (Hymenoptera, Formicidae) collected in Ulu Gombak, Peninsular Malaysia
A colony of Protanilla sp. was collected from the floor of a selectively logged forest in Ulu Gombak, Peninsular Malaysia, in March 2011. The colony...

Study on the anatomy of the pink mealybug Maconellicoccus hirsutus (Hemiptera: Pseudococcidae) using stereo microscopy
An internal anatomy of the adult female pink mealybug, Maconelicoccus hirsutus (Green) (Hemiptera: Coccoidea: Pseudococcidae) was examined using...

Impact of starvation on paternal reproductive investment in Neoseiulus californicus
Neoseiulus californicus is an important biological control agent of small arthropod pests, widely used in preventive releases at low prey densities....

Pre-copulatory choices drive post-copulatory decisions: mechanisms of female control shift across different life stages
BackgroundThe ‘wallflower’ hypothesis proposes females mate indiscriminately to avoid reproductive delays. Post-copulatory mechanisms may then allow...

Damage and spatiotemporal dynamics of the Ngaio flat mite, Brevipalpus ferraguti (Trombidiformes: Tenuipalpidae), with observations on the development of the female insemination system
We studied the Ngaio flat mite, Brevipalpus ferraguti Ochoa & Beard, on Myoporum laetum (Scrophulariaceae), a common introduced plant used as...

Abundant small RNAs in the reproductive tissues and eggs of the honey bee, Apis mellifera
BackgroundPolyandrous social insects such as the honey bee are prime candidates for parental manipulation of gene expression in offspring. Although...
