Regulatory mechanisms of reproduction in locusts and grasshoppers
New Plant Protection, EarlyView.Regulatory networks composed of numerous coding and noncoding genes play crucial roles in the reproduction of locusts and grasshoppers. This review integrates mechanistic advances in reproductive regulation, highlighting environmentally adaptive pathways and providing prospective targets for eco‐friendly pesticides.

Mechanisms for type-II vitellogenesis-inhibiting hormone suppression of vitellogenin transcription in shrimp hepatopancreas: Crosstalk of GC/cGMP pathway with different MAPK-dependent cascades. [PDF]
PLoS ONE, 2018 Vitellogenesis is the process of yolk formation via accumulating vitellin (Vn) with nutrients in the oocytes. Expression of vitellogenin (Vg), the precursor of Vn, is one of the indicators for the start of vitellogenesis.

Vitellogenin receptors during vitellogenesis in the rainbow trout Oncorhynchus mykiss [PDF]
, 1996 Rainbow trout vitellogenin receptors have been characterized by ligand blotting and Scatchard analysis. Their evolution has been studied over a reproductive cycle in a broodstock of 2-year-old females.

Vitellogenesis and choriogenesis in fishes [PDF]
Fisheries Science, 2016 In studies of sex discrimination in fish in the early 1900s, a specific antigen in the blood of gravid females was identified using immunological methods. At present, this specific antigen is known as vitellogenin, the major precursor of egg yolk protein that is synthesized in the female liver and is secreted into the blood to be incorporated into the ...

New Plant Protection, EarlyView.Flight in female beet webworms (Loxostege sticticalis) promotes an increase in feeding, thereby enhancing abdominal energy reserves. Following flight, the flight muscles undergo accelerated histolysis, and the energy substances undergoing histolysis are redirected to the ovaries. These two processes collectively promote ovarian development.

Zoologia (Curitiba), 2015 The reproductive cycle of Squamata reptiles is often associated with environmental conditions, such as rainfall. In this respect, seasonal variations may affect the morphology of the ovarian follicles, which are associated with vitellogenesis.

Pest Management Science, EarlyView.Female boll weevils feeding on flower buds promote reproduction regardless of their immature diet, whereas boll feeding increases lipid reserves and lifespan, revealing a nutrition‐driven trade‐off that sustains survival and reproduction in tropical boll weevil populations.

Nuclear Receptors in Mosquito Vitellogenesis [PDF]
American Zoologist, 1999 Synopsis. Vitellogenesis in insects involves the coordinated activity of the fat body, which produces large amounts of yolk protein precursors (YP), and oocytes, which specifically accumulate these proteins. The expression of YP genes is achieved through strict sex-, tissue-, and hormone-specific control in the female fat body.
