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.

Contributions to the Knowledge of the Larval Morphology of Synalpheus Spence Bate, 1888 (Caridea: Alpheidae): Description of the First Zoea of S. antillensis Coutière, 1909 and S. cf. townsendi Coutière, 1909 Reared in Laboratory

Acta Zoologica, EarlyView.
ABSTRACT The first zoea of two Synalpheus species, namely: S. antillensis and S. cf. townsendi, are herein described. They were also compared with the genus descriptions and with their respective species complexes available in the literature. Morphological information on Synalpheus zoea I exhibits an increase from 19 to 21 species, and it corresponds ...

Someone like it hot? Effects of global warming on insect immunity and microbiota

Invertebrate Survival Journal, 2012
Global warming represents a substantial challenge on a broad range of organisms with diverse life-history traits and geographical distributions. Up till now several studies correlated global warming to changes in body mass, growth rate or fat content ...

Rifaximin ameliorates memory impairment and Alzheimer's pathological changes in APP/PS1 mice associated with changes in the gut microbiome–bile acids–serum metabolites networks

British Journal of Pharmacology, EarlyView.
Background and Purpose Modifying the brain–gut–microbiota axis has emerged as a promising therapeutic strategy against Alzheimer's disease (AD). Whether rifaximin, a non‐absorbed and non‐systemic antibiotic, can be applied to the treatment of AD remains unexplored.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

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.

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

Ecological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...

Maternal factors from a parasitoid wasp mediate hyperparasitoid attraction to parasitized caterpillars

Ecological Entomology, EarlyView.
The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...
