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

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.

Endosymbion microbials low abundance of Nilaparvata lugens (Stal) (Hemiptera: Delphacidae) from Indonesia rice production center based on metagenomic study using 16Sr RNA [PDF]

BIO Web of Conferences
Insects have a long history of association with endosymbiont microbes. There are several indications that endosymbiont microbes are associated with insects and participate in the degradation of organic and inorganic molecules.

Symbiotic Life of Echinoderm Larvae

Frontiers in Ecology and Evolution, 2020
Echinoderm larvae have served as a fundamental system for understanding development and life history evolution over much of the last century. In the last few decades, our understanding of echinoderm larvae has expanded to the microbiota that they ...

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.

Population genetic analysis of the endangered Mottled Duskywing butterfly (Erynnis martialis) informs species reintroduction

Insect Conservation and Diversity, EarlyView.
Mottled Duskywing (Erynnis martialis) populations had moderate levels of genetic diversity at microsatellites with expected heterozygosity ranging from 0.43 to 0.58, and populations more than 10 km apart were differentiated from one another. Weak patterns of isolation by distance and low effective population sizes suggest that all but the largest ...

Rhizobiales as functional and endosymbiontic members in the lichen symbiosis of Lobaria pulmonaria L.

Frontiers in Microbiology, 2015
Rhizobiales (Alphaproteobacteria) are well-known beneficial partners in plant-microbe interactions. Less is known about the occurrence and function of Rhizobiales in the lichen symbiosis, although it has previously been shown that Alphaproteobacteria are

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

Insect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Spatially Varying Wolbachia Frequencies Reveal the Invasion Origin of an Agricultural Pest Recently Introduced From Europe to North America

Evolutionary Applications
The introduction of non‐native species across the world represents a major global challenge. Retracing invasion origin is an important first step in understanding the invasion process, often requiring detailed sampling within the native range.

Conflict in the Intracellular Lives of Endosymbionts and Viruses: A Mechanistic Look at Wolbachia-Mediated Pathogen-blocking

Viruses, 2018
At the forefront of vector control efforts are strategies that leverage host-microbe associations to reduce vectorial capacity. The most promising of these efforts employs Wolbachia, a maternally transmitted endosymbiotic bacterium naturally found in 40%
