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.

Reactive oxygen species, antioxidants and the regulation of plant development

The FEBS Journal, EarlyView.
The regulation of axillary bud outgrowth by the interplay between phytohormone and redox signals. Axillary bud outgrowth is regulated by cellular energy status and the balance between phytohormones, notably abscisic acid (ABA) and gibberellic acid (GA).

Development of an Artificial Liquid Diet for Allelochemical Delivery in Lycorma delicatula

Journal of Applied Entomology, EarlyView.
ABSTRACT Spotted lanternfly, Lycorma delicatula White (Hemiptera: Fulgoridae), is an invasive phloem‐feeding planthopper native to Asia, which poses a growing threat to US agriculture due to its broad host range and rapid spread since its 2014 detection. To better understand how L.

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...

Oviposition Behaviour, Nymphal Development and Below‐Ground Olfactory Preference of Pentastiridius leporinus on 12 Beta vulgaris Genotypes

Journal of Applied Entomology, EarlyView.
ABSTRACT The planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) is the primary vector of two phloem‐restricted prokaryotes, which can cause the disease syndrome de basses richesses (SBR) in sugar beet (Beta vulgaris L.). Heavy infestations of this insect have contributed to significant yield losses in Central Europe, but little is known about ...

Field Attraction of Natural Enemies to Methyl Salicylate Differs Between Annual and Perennial Cropping Systems

Journal of Applied Entomology, EarlyView.
ABSTRACT Methyl salicylate (MeSA) is an herbivore‐induced plant volatile (HIPV) known to attract natural enemies of herbivores; however, its effectiveness as a semiochemical across diverse cropping systems and broad geographic regions remains unclear. In this 2‐year field study, we sampled natural enemies using MeSA‐baited and unbaited (control) yellow

First Detailed Record of Jikradia olitoria (Hemiptera: Cicadellidae) in the Swiss Southern Alps and Evaluation of Its Current Potential as a Vector of 16SrV‐Phytoplasmas

Journal of Applied Entomology, EarlyView.
ABSTRACT Jikradia olitoria Say is a Nearctic leafhopper that was recently reported in several European countries. Given its role as the vector of phytoplasmas associated with Grapevine Yellows diseases (GYD) in its native range, its presence in European vineyard agroecosystems could represent an important phytosanitary risk.

The ZmRACK1–ZmCDPK7–ZmAPX1 module regulates plant antiviral immunity

Journal of Integrative Plant Biology, EarlyView.
In maize, ZmRACK1 acts as a scaffold protein that bridges the cyclin‐dependent kinase ZmCDPK7 and the ascorbate peroxidase ZmAPX1, promoting ZmAPX1 activity to mitigate MCMV infection. Upon viral infection, P31 obstructs formation of the ZmRACK1‐ZmCDPK7‐ZmAPX1 complex, inhibiting ZmCDPK7‐mediated ZmAPX1 activity and promoting reactive oxygen species ...
