Thermosensory TRPV Heterotetramers Drive Seasonal Polyphenism: Molecular Basis of CcIav/CcNan‐PKCα‐AKH/AKHR Signaling in Pear Psyllid Morph Transition

Advanced Science, Volume 12, Issue 45, December 4, 2025.
At 2 5 °C, thermal activation initiates: i) CcIav/CcNan heterotetramer assembly → Ca2⁺ influx; ii) CcPKCα phosphorylation → AKH signaling potentiation; iii) CcAKH1 binding to membrane‐localized CcAKHR → energy mobilization (lipid catabolism/glycogenolysis) and vitellogenin transport via follicular patency; iv) Oocyte maturation → summer‐form nymph ...

Increases in Genistein in Medicago sativa Confer Resistance against the Pisum Host Race of Acyrthosiphon pisum

Insects, 2019
Interspecific interaction with host plants have important consequences for the host race formation of herbivorous insects. Plant secondary metabolites, particularly those that are involved in host races specializing on plants, warrant the theory of host ...

Pea aphids (Hemiptera: Aphididae) have diurnal rhythms when raised independently of a host plant [PDF]

, 2016
Seasonal timing is assumed to involve the circadian clock, an endogenous mechanism to track time and measure day length. Some debate persists, however, and aphids were among the first organisms for which circadian clock involvement was questioned ...

Microinjection‐enabled gene silencing in first instar larvae of western flower thrips, Frankliniella occidentalis, reveals vital genes for larval survival

Insect Science, Volume 32, Issue 6, Page 1969-1981, December 2025.
This study introduces a microinjection technique to deliver dsRNA into the hemolymph of first instar larval thrips (L1s) via the foreleg coxa, enhancing survival rates by minimizing internal tissue damage. Significant knockdown of V‐ATPase‐B, CYP3653A2, and ApoLp‐II/I was achieved, with silencing of CYP3653A2 or ApoLp‐II/I increasing larval mortality ...

A catalogue of aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) from India [PDF]

, 2011
A catalogue of aphidiine parasitoids (Hymenoptera: Braconidae: Aphidiinae) associated with various aphids species occurring in India was compiled. The present catalogue with 125 species under 22 genera has been further reinforced with not only all the ...

Benefits from below: silicon supplementation maintains legume productivity under predicted climate change scenarios [PDF]

, 2018
Many studies demonstrate that elevated atmospheric carbon dioxide concentrations (eCO2) can promote root nodulation and biological nitrogen fixation (BNF) in legumes such as lucerne (Medicago sativa).

How a Melanism Mutant Responds to Different Temperatures: A Case Study in Ladybird Beetle Harmonia axyridis Demonstrating Thermal‐Induced Phenotypic Plasticity

Ecology and Evolution, Volume 15, Issue 11, November 2025.
ml, inherited in a Mendelian autosomal recessive manner, is a novel melanism mutant of Harmonia axyridis. When compared to wt, ml exhibited vastly smaller changes in the occurrence frequencies of dark spots on both the dorsal cuticles of pupa and elytra in response to thermal variations. ml had very high melanin level even at 32.5°C and showed a higher

An epigenomic threshold hypothesis for integrating dynamic environmental signals into functional models of developmental polyphenisms

Functional Ecology, Volume 39, Issue 11, Page 3050-3060, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions between developing embryos and a multitude of environmental factors (e.g. climate, nutrition, social cues, stress and anthropogenic contaminants) underlie adaptive and non‐adaptive developmental plasticity and carry broad implications across ecological ...

Interspecific recognition based on cuticular hydrocarbons mediates reproduction control in aphids

Scientific Reports
The preset study tested whether an aphid species can control its reproduction by recognizing the presence and density of a rival species. Acyrthosiphon pisum and Megoura crassicauda often coexist on the same leguminous plant.

Was Dan Janzen (1977) right about aphid clones being a "super-organism", i.e. a single "evolutionary individual"? : new insights from the use of molecular marker systems [PDF]

, 2008
Dan Janzen proposed in a paper in 1977 (loc. cit.), that a clone of aphids and for that matter dandelions consists, respectively, of one large ‘super-organism’.
