Rhizobia–Bean Symbiosis Increases Root Herbivore Attraction and Growth via Volatile Signals and Enhanced Nutrition

open access: yesPlant, Cell &Environment, Volume 49, Issue 7, Page 3952-3962, July 2026.
ABSTRACT The symbiosis between nitrogen‐fixing rhizobia and plants is considered mutually beneficial, yet its indirect effects on other organisms remain understudied. We examined how rhizobia symbiosis in Phaseolus vulgaris influences the behaviour and performance of Diabrotica balteata larvae. Specifically, we tested larval preference for nodulated (R+

Density dependence of the alarm pheromone effect in pea aphids, Acyrthosiphon pisum (Sternorrhyncha: Aphididae)

open access: yesEuropean Journal of Entomology, 2007
The aphid alarm pheromone is known to trigger wing induction in pea aphids (Acyrthosiphon pisum). In reaction to alarm pheromone, aphids drop off the plant or walk away.

Water use efficiency and productivity of dryland grain sorghum and cowpea intercrops in distinct semi‐arid conditions

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract An intercropping system is one of the traditional practices adopted under dry conditions due to its ability to utilize resources efficiently. There is limited information on water use efficiency (WUE) and water equivalent ratio (WER) of grain sorghum (Sorghum bicolor)‐cowpea (Vigna unguiculata) intercrop grown in different agroecological ...

Influence of host plant on susceptibility of the aphid Acyrthosiphon pisum (Hemiptera: Aphididae) to the fungal pathogen Pandora neoaphidis (Zygomycetes: Entomophthorales)

open access: yesEuropean Journal of Entomology, 2007
The performance of the aphid-specific fungal pathogen Pandora neoaphidis was studied in relation to changes in herbivore resources for the pea aphid, Acyrthosiphon pisum, on different host plant species.

Aphid alarm pheromone (E)‐β‐farnesene: mechanisms, applications, and challenges in pest management

open access: yesNew Plant Protection, Volume 3, Issue 2, June 2026.
This review highlights the advances in the application of the aphid alarm pheromone (E)‐β‐farnesene (EβF) for pest management. It focuses on smart delivery systems, molecular optimization, synthetic biology, and integration with digital agriculture. Additionally, it discusses key challenges and future directions for enhancing stability, field efficacy,

Native Regiella Endosymbionts Provide Strong Parasitoid Protection With Limited Impacts on Fitness and Virus Transmission in Myzus persicae

open access: yesEnvironmental Microbiology, Volume 28, Issue 6, June 2026.
Native Regiella insecticola in Myzus persicae provides strong protection against parasitoid wasps but imposes only modest reproductive costs and does not affect virus transmission. Despite stable vertical and horizontal transmission, these effects alone do not explain the low natural prevalence of **Regiella** in field populations.

Induced Systemic Resistance by a Plant Growth-Promoting Rhizobacterium Impacts Development and Feeding Behavior of Aphids

open access: yesInsects, 2020
The effects of microorganisms on plant-insect interactions have usually been underestimated. While plant growth-promoting rhizobacteria (PGPR) are known to induce plant defenses, endosymbiotic bacteria hosted by herbivorous insects are often beneficial ...

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

open access: yesInsect Molecular Biology, Volume 35, Issue 3, Page 217-231, June 2026.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Seasonal dynamics of: the pea aphid, Acyrthosiphon pisum (Harris), its natural enemies the seven spotted lady beetle Coccinella septempunctata Linnaeus and variegated lady beetle Hippodamia variegata Goeze, and their parasitoid Dinocampus coccinellae (Schrank)

open access: yesJournal of Plant Protection Research, 2015
Two important lady beetle species commonly found in alfalfa fields in Iran are the variegated lady beetle Hippodamia variegata Goeze and the seven spotted lady beetle Coccinella septempunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae).

Methionine Synthase Positively Regulates Plant Defence to Both RNA and DNA Viruses and Is Useful for Developing Broad‐Spectrum Antiviral Resistance in Crops

open access: yesPlant Biotechnology Journal, Volume 24, Issue 6, Page 3821-3839, June 2026.
ABSTRACT Plant viruses frequently cause severe economic losses in worldwide crop production. Developing broad‐spectrum resistance is the most efficient approach for controlling plant viral diseases. In this work, we found that the 17K protein of barley yellow dwarf viruses (BYDVs), which has multiple functions in viral pathogenesis including acting as ...
