Calcitonin‐like diuretic hormone influences reproduction in adult female Rhodnius prolixus

Insect Science, EarlyView.
Highlights • CT/DH‐like immunoreactivity is present in female reproductive tissues • CT/DH receptor transcripts are expressed in the fat body and ovaries • RNAi knockdown of CT/DH receptors reduces egg number and hatching rate • Rhopr‐CT/DH increases RhoprVg1 and RhoprVgR expression in ovaries in vitro • Rhopr‐CT/DH stimulates oviduct contractions in a

A capsidless (+)RNA yadokarivirus hosted by a dsRNA virus is infectious as particles, cDNA, and dsRNA

Journal of Virology
Capsidless yadokariviruses (members of the order Yadokarivirales) with (+)RNA genomes divert the capsid of their partner icosahedral double-stranded RNA (dsRNA) viruses in different families of the order Ghabrivirales into the replication site.

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

Insect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

TcALS knockdown accelerates metamorphosis via insulin signaling in Tribolium castaneum

Insect Science, EarlyView.
RNAi silencing of TcALS accelerates larva‐to‐pupa metamorphosis in Tribolium castaneum. Abstract Insect metamorphosis is an evolutionary adaptation precisely regulated by nutritional and hormonal cues. The red flour beetle Tribolium castaneum, a major stored‐product pest, serves as an excellent model for studying this process.

Exchange of the C-terminal part of VP3 from very virulent infectious bursal disease virus results in an attenuated virus with a unique antigenic structure [PDF]

, 2002
Infectious bursal disease virus (IBDV) is the major viral pathogen in the poultry industry. Live attenuated serotype 1 vaccine strains are commonly used to protect susceptible chickens during their first 6 weeks of life. Wild-type serotype 1 IBDV strains

Prostaglandin E2 (PGE2) signaling regulates fluid excretion and uric acid metabolism in the mosquito Anopheles gambiae

Insect Science, EarlyView.
Prostaglandin E2 (PGE2) signaling via its receptor has integral roles in mosquito physiology, mediating fluid excretion, stimulating hindgut contractions, and in modulating uric acid levels. Together, these results uncover previously unrecognized roles of prostaglandin signaling in osmotic balance and metabolic homeostasis in mosquitoes.

Regulated localization of transposable element RNA during influenza A virus infection

EMBO Reports
Influenza A virus (IAV) infection triggers derepression of host transposable elements (TEs), which have the potential to form double-stranded (ds)RNAs and could enhance innate antiviral immunity.

ZAP inhibits double-stranded RNA virus infection by degrading negative-strand RNA and blocking the elongation phase of viral protein synthesis

Cell Reports
Summary: Zinc-finger antiviral protein (ZAP) is a crucial host restriction factor that recognizes CpG dinucleotides in single-stranded RNAs, yet its role in double-stranded RNA (dsRNA) virus replication remains uncharacterized.
