Control of two sucking insect pests, a whitefly (Bemisia tabaci) and a thrips (Frankliniella occidentalis), infesting hot peppers by spraying LDH‐formulated dsRNA

open access: yesPest Management Science, Volume 81, Issue 12, Page 8163-8178, December 2025.
A vacuolar type ATPase subunit B (vATPase‐B) gene is identified and expressed in the midgut of Bemisia tabaci and Frankliniella occidentalis. The double‐stranded RNA (dsRNA) specific to vATPase‐B was expressed in hot peppers by virus‐induced gene silencing (VIGS) and killed both whitefly and thrips.

Ecdysone signaling induces two phases of cell cycle exit in Drosophila cells

open access: yesBiology Open, 2016
During development, cell proliferation and differentiation must be tightly coordinated to ensure proper tissue morphogenesis. Because steroid hormones are central regulators of developmental timing, understanding the links between steroid hormone ...

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection

open access: yesInsect Science, Volume 32, Issue 6, Page 2105-2124, December 2025.
Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of

New reporter gene assays for detecting natural and synthetic molting hormone agonists using yeasts expressing ecdysone receptors of various insects

open access: yesFEBS Open Bio, 2017
Synthetic nonsteroidal ecdysone agonists, a class of insect growth regulators (IGRs), target the ecdysone receptor (EcR), which forms a heterodimer with ultraspiracle (USP) to transactivate ecdysone response genes.

Population Genomics of Incipient Allochronic Divergence in the Pine Processionary Moth

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Allochronic divergence is a key evolutionary mechanism that can frequently lead to incipient speciation. Although theoretical models suggest that such divergence is notably facilitated by small population size and genetic polymorphisms influencing reproductive timing, though constrained by genetic load, empirical validation remains limited. We

Mechanisms For The Environmental Regulation Of Gene Expression: Ecological Aspects Of Animal Development [PDF]

open access: yes, 2005
The environment can play a significant role in the production of phenotypes. However, the developmental mechanisms by which the environmental agents effect normal development are Just becoming known. At least three paths have been found through which the

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

open access: yesFunctional 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 ...

Discovery of progenitor cell signatures by time-series synexpression analysis during Drosophila embryonic cell immortalization [PDF]

open access: yes, 2015
The use of time series profiling to identify groups of functionally related genes (synexpression groups) is a powerful approach for the discovery of gene function. Here we apply this strategy during RasV12 immortalization of Drosophila embryonic cells, a

APPi: A Multiscale Qualitative–Quantitative Insecticide‐Likeness Evaluation Platform and Application

open access: yesPlant Biotechnology Journal, Volume 23, Issue 11, Page 4844-4856, November 2025.
An Agrochem Predictive Platform for Insecticide‐likeness: From Qualitative Rules to Quantitative Modeling and Visualization. ABSTRACT According to the Food and Agriculture Organization of the United Nations (FAO), pests reduce global crop production by 14% annually. The growing challenge of pest resistance, coupled with the relatively low success rates
