Regulatory mechanisms of reproduction in locusts and grasshoppers

open access: yesNew 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.

Global proteomics analysis of testis and ovary in adult zebrafish ( Danio rerio ) [PDF]

open access: yes, 2018
The molecular mechanisms controlling sex determination and differentiation in zebrafish (Danio rerio) are largely unknown. A genome-wide analysis may provide comprehensive insights into the processes involved.

Biosynthesis of mosquito vitellogenin.

open access: yesJournal of Biological Chemistry, 1990
Vitellogenin (Vg), the hemolymph precursor to the major yolk protein in mosquitoes, is synthesized in the fat body of blood-fed females. Mosquito Vg consists of two subunits with Mr = 200,000 and 66,000. Here, we demonstrate that both the Vg subunits are first synthesized as a single precursor.

Juvenile hormone‐mediated accelerated post‐flight recovery of ovarian development in Loxostege sticticalis (Lepidoptera: Crambidae)

open access: yesNew 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.

From flower buds to bolls: how cotton reproductive structures shape boll weevil development, reproduction and survival

open access: yesPest 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.

Oogenesis and Egg Quality in Finfish: Yolk Formation and Other Factors Influencing Female Fertility

open access: yesFishes, 2018
Egg quality in fishes has been a topic of research in aquaculture and fisheries for decades as it represents an important life history trait and is critical for captive propagation and successful recruitment.

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

open access: yesPest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Identification and partial characterization of Olyra longicaudata (McClelland, 1842) vitellogenins: Seasonal variation in plasma, relative to estradiol-17β and ovarian growth

open access: yesAquaculture Reports, 2016
This study aims at immunochemical characterization of plasma vitellogenin (VTG), development of an heterlogous VTG ELISA and to relate seasonal variation in plasma VTG and estradiol-17β (E2) levels with ovarian growth (gonadosomatic index, GSI) in Olyra ...

Transcriptome sequencing reveals high isoform diversity in the ant Formica exsecta [PDF]

open access: yes, 2017
Transcriptome resources for social insects have the potential to provide new insight into polyphenism, i.e., how divergent phenotypes arise from the same genome.

Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...
