A horizontally acquired pantothenate gene drives vitellogenin's benefit to whitefly symbiosis persistence

Insect Science, EarlyView.
This diagram illustrates that the horizontally transferred panBC influences the level and localization of vitellogenin (Vg) by facilitating pantothenate production and juvenile hormone (JH) biosynthesis. In turn, Vg shields symbionts by suppressing autophagic degradation in bacteriocytes.

Aphid and endosymbiont sensitivity to heatwaves is misaligned across life stages

Insect Science, EarlyView.
Aphids depend on the obligate symbiont Buchnera aphidicola, which may constrain thermal tolerance. Using a factorial heatwave experiment, we exposed nymphs and adults to moderate or extreme temperatures and measured fitness and symbiont responses.

HGTScanner: Detecting horizontal gene transfer at the fine scale using whole organelle genomes

Methods in Ecology and Evolution, EarlyView.
Abstract Horizontal gene transfer (HGT) has profoundly shaped eukaryotic organellar genomes like plant mitochondria. Yet no generalized tools are currently available to efficiently characterize HGT across these genomes due to both high structural complexity and low sequence divergence compared to prokaryotic HGTs.

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

Reconsidering the importance of Metopolophium dirhodum (Walker) (Hemiptera: Aphididae) as a crop pest

Agricultural and Forest Entomology, EarlyView.
Four‐year field monitoring and laboratory studies revealed M. dirhodum occurs regularly in barley with high reproductive potential and extended adult longevity. Populations peaked during vulnerable crop stages, creating optimal conditions for BYDV transmission during critical infection windows. M.

Behavioural responses of peach potato aphid, Myzus persicae Sulzer (Hemiptera: Aphididae), to entomopathogenic fungi infected conspecifics

Agricultural and Forest Entomology, EarlyView.
Myzus persicae showed no detectable behavioural response to Beauveria bassiana‐colonised agar alone. Aphids spent significantly more time in odour fields containing EPF‐infected conspecifics than healthy aphids, agar or blank air. EPF infection may alter host‐associated odours, suggesting pathogen‐mediated cues could influence aphid behaviour and ...

The parasitoids of Myzus spp. (Aphididae: Hemiptera) and their distribution in India [PDF]

Arthropods
In this study, the parasitoids of 12 species of Myzus Passerini, 1860 (Aphididae: Hemiptera) are enlisted along with their host aphids and host plants distributed in different states and union territories of India.

Impact of food scarcity on the foraging dynamics of Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae) Impacto da escassez de alimentos na dinâmica de forrageamento de Eriopis connexa (Germar, 1824) (Coleoptera: Coccinellidae)

Agricultural and Forest Entomology, EarlyView.
Starvation duration alters predatory behaviour of Eriopis connexa, affecting aphid consumption and survival dynamics. Increased starvation enhances attack rate, accelerating prey depletion without substantially affecting handling time. Functional response remains type II, with stronger predation under prolonged food deprivation.

A global assessment of the viruses transmitted by the peach‐potato aphid (Myzus persicae)

Agricultural and Forest Entomology, EarlyView.
The viruses transmitted by Myzus persicae, including proportions by family, order and transmission type (persistent, semi‐persistent and non‐persistent), are provided. Latin binomials and common names are documented for each virus Virus presence in GB matches well with the rest of NW Europe, but with 25 exceptions.
