Status of ash (Fraxinus spp.) in mixed hardwood post‐outbreak forests near the epicentre of the emerald ash borer invasion

Agricultural and Forest Entomology, EarlyView.
The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

Agricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Host desiccation and interspecific competition limit reproductive performance of a bark beetle

Agricultural and Forest Entomology, EarlyView.
At high and moderate phloem moisture levels, Polygraphus proximus reproductive success was suppressed by sympatric species density. At low phloem moisture, P. proximus reproductive success was suppressed by the low phloem moisture regardless of the Cryphalus laricis hole density. Conspecific density (i.e., attack density of P.

miRNA accumulation correlates with increased phloem cell proliferation in tomato hawaiian skirt mutants

Frontiers in Plant Science
IntroductionThe cambium is the meristem responsible for production of plant vascular tissues, the xylem (wood) and phloem, during plant radial growth. Due to its internal location and relatively low cell number, the biology of the cambium remains less ...

Between Gaps and Voids: An Archaeometrical Study of Degraded Fibers in a Sherd From the Cueva dos Chinches Muertas, Siltzul (Raxruha, Alta Verapaz, Guatemala)

Archaeometry, EarlyView.
ABSTRACT In 2019, excavations at the Cueva dos Chinches Muertas carried out by the Raxruha Viejo Project uncovered a small ceramic sherd distinguished by a stratified structure composed of multiple layers of textile imprints, both superficial and transversal.

Low Temperature Tolerance of Peach Flower Buds and Shoot Tissues Is Differentially Influenced by Freezing and High Temperature Exposure

HortScience
In northern temperate zones, peach trees are vulnerable to cold temperature injury in the fall, particularly as climate change prolongs warm weather in the fall and potentially delays the onset of cold acclimation.

Interaction between carrot root dimensions and puncture force [PDF]

Journal on Processing and Energy in Agriculture, 2011
The aim of this research was to determine quantitatively carrot root mass and dimensions depending on the cultivation type (flat ground and ridge), as well as to determine the differences in the root texture by measuring the puncture force in xylem and ...

Methyl Jasmonate and Methyl Salicylate Differentially Modulate Direct and Indirect Defenses in Coffee Plants Against the White Mealybug

Entomologia Experimentalis et Applicata, EarlyView.
MeJA application strengthened both direct and indirect coffee defenses against the white mealybug Planococcus citri, whereas the effects of MeSA were variable and context‐dependent across the defensive traits examined. The combined application of both elicitors produced an effect similar to MeSA on direct defenses, but resembled MeJA when indirect ...

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

Ecological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.
