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

To seal a wound, caterpillars transform blood from a viscous to a viscoelastic fluid in a few seconds

Frontiers in Soft Matter
In insects vulnerable to dehydration, the mechanistic reaction of blood after wounding is rapid. It allows insects to minimize blood loss by sealing the wound and forming primary clots that provide scaffolding for the formation of new tissue.

Investigations into Aldefluor as a Novel Method for Identifying Leukemia in Soft-Shell Clams [PDF]

, 2014
The clam species Mya arenaria is a common model organism in leukemia research. The current method for classifying the degree of cancer progression is by examining cell morphology with light microscopy.

Is there a causal association between genotoxicity and the imposex effect? [PDF]

, 2006
There is a growing body of evidence that indicates common environmental pollutants are capable of disrupting reproductive and developmental processes by interfering with the actions of endogenous hormones.

Rapid hormonal rise in honey bees due to heat‐shock is mitigated by a primer pheromone

Insect Science, EarlyView.
We show that honey bee foragers increased juvenile hormone (JH) titers significantly after heat‐shocked for 1 h at 40 °C, but this increase is dependent on social conditions. Increase of JH titers only happened when bees were isolated (one worker bee per vial) but not in groups.

Hemolymph composition, gene expressions in the gills, and thus the survival of euryhaline crabs are controlled by ambient minor cations according to osmotic condition‐dependent manner

Ecology and Evolution, 2020
Na+ and Cl− are the most abundant dissolved ions in seawater, constituting ~ 85% of total ions. They significantly affect the osmolality of body fluids of marine invertebrates.

Effect of Escherichia coli endotoxin on Archachatina marginata haemolymph coagulation system [PDF]

, 2010
The effect of _E. coli_ endotoxin on the heamolymph coagulation response of _Archachatina marginata_ was studied. Heamocyte Lysate(HL), Haemocyte Lysate Supernatant(HLS) and Haemocyte Lysate Debris (HLD) were exposed to _Escherichia coli_ endotoxin ...

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.

Enhanced activities of acetylcholinesterase, acid and alkaline phosphatases in Helicoverpa armigera after exposure to entomopathogenic fungi

Invertebrate Survival Journal, 2017
The toxicity of entomopathogenic fungi, Metarhizium anisopliae (isolates Ma-11.1 and Ma-4.1), Isaria fumosorosea (isolates If-02 and If-2.3) and Beauveria bassiana (isolates Bb-01 and Bb-08) to Helicoverpa armigera was assessed by measuring the activity ...
