An RNA interference biopesticide reduces reproduction of the honey bee parasite Varroa destructor by down‐regulating embryo development pathways

open access: yesPest Management Science, Volume 82, Issue 3, Page 2694-2707, March 2026.
Varroa destructor mites exposed to dsRNA specific in sequence to a V. destructor calmodulin gene significantly effected gene expression of adult female mites sampled 5 days after entering a honey bee brood cell to reproduce. Significantly down‐regulated genes included Calmodulin and were associated with calcium ion binding and embryo developmental ...

Ultrastructural aspects of vitellogenesis in Archegozetes longisetosus Aoki, 1965 (Acari, Oribatida, Trhypochthoniidae)

open access: yesSoil Organisms, 2010
We studied the process of vitellogenesis in the oribatid mite Archegozetes longisetosus using light and electron microscopy. Both vitellogenesis and the formation of the first egg shell occur within the meroi of the ovary, starting after detachment from

The archaeal class Nitrososphaeria is a key component of the reproductive microbiome in sponges during gametogenesis

open access: yesmBio
Sponge-associated microbes play fundamental roles in regulating their hosts’ physiology, yet their contribution to sexual reproduction has been largely overlooked.

Reproductive biology, spawning season, and growth of female rex sole (Glyptocephalus zachirus) in the Gulf of Alaska [PDF]

open access: yes, 2006
Rex sole (Glyptocephalus zachirus) have a wide distribution throughout the North Pacific, ranging from central Baja California to the western Bering Sea. Although rex sole are an important species in the commercial trawl fisheries off the U.S. West Coast,

Cellular distribution of a feminizing microsporidian parasite: a strategy for transovarial transmission [PDF]

open access: yes, 1997
The cellular distribution of a vertically transmitted, feminizing microsporidian was followed in its host Gammarus duebeni. In adult females the parasite was restricted to gonadal tissue, in particular primary and secondary follicle cells.

The dynamic landscape of gene regulation during Bombyx mori oogenesis

open access: yesBMC Genomics, 2017
Background Oogenesis in the domestic silkworm (Bombyx mori) is a complex process involving previtellogenesis, vitellogenesis and choriogenesis. During this process, follicles show drastic morphological and physiological changes.

Dietary Supplementation With Icariin Affects Estrogen Synthesis, Vitellogenesis, and Oocyte Development in the Chinese Mitten Crab, Eriocheir sinensis

open access: yesFrontiers in Marine Science, 2020
In Eriocheir sinensis aquaculture, crabs feeding on an artificial diet without steroid hormones available in ice-fresh fish or snails show delayed ovarian maturation and late listing.

Geographic Divergence and the Genomic Basis of Reproductive Diapause in Drosophila triauraria

open access: yesMolecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Adjusting reproduction timing to environmental cues is essential for lifetime fitness. In many insects, reproductive diapause shows clinal variation along environmental gradients such as photoperiod and temperature. How such continuous trait variation may be encoded at the molecular level and maintained in the presence of gene flow remains ...
