Phloem-restricted parasites of Palms. Focus on the coconut palm [PDF]

, 2010
There is a category of palm diseases that raises many investigation problems: lethal diseases caused by phloem-restricted parasites and transmitted by vector insects.

Developing together: The elementome and biogeochemical niche of the mutualistic occupants of a fig microcosm

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In brood‐site pollination mutualisms, where flowers provide nutrition and shelter to pollinator offspring in exchange for pollination, resource allocation to inflorescences is directly related to plant and pollinator fitness.

Green thermoelectrics: Observation and analysis of plant thermoelectric response

, 2015
Plants are sensitive to thermal and electrical effects; yet the coupling of both, known as thermoelectricity, and its quantitative measurement in vegetal systems never were reported.

Complex multitrophic species interactions and fitness costs: Intricate consequences of jasmonate and salicylate induced plant defences

Journal of Animal Ecology, EarlyView.
This study reveals how long‐term activation of jasmonic and salicylic acid signalling reshapes arthropod communities and plant fitness across seasons. By showing that induced defences generate contrasting outcomes and cascading trade‐offs across trophic levels, it challenges the assumption that induced resistance is uniformly beneficial in natural ...

The social life of money for children

The British Journal of Sociology, EarlyView.
Abstract Inspired by Nigel Dodd's The Social Life of Money, this article proposes an analysis of entangled economic lives, that is, how meaning, structures and politics jointly shape the flow of monies within households. The past decades have marked a shift from “childrearing expenditures” to “parenting investments” that align with new visions of both ...

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

Insect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

Insect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

LsFAMeT and LsJHAMT coordinate JH biosynthesis to regulate fecundity in Laodelphax striatellus

Insect Science, EarlyView.
The small brown planthopper (SBPH), Laodelphax striatellus, can trigger large‐scale outbreaks when encountering suitable habitats during migration due to their strong reproductive ability. This study investigated the role of juvenile hormone (JH) in regulating SBPH reproduction.

Tissue location of resistance in apple to the rosy apple aphid established by electrical penetration graphs [PDF]

, 2009
A study of the constitutive resistance of the apple cultivar Florina, Malus domestica Borkh. (Rosaceae), to the rosy apple aphid, Dysaphis plantaginea (Passerini) (Homoptera Aphididae), was performed for the first time by the electrical penetration graph
