A miR-JL-5 inhibitor modulates the proliferation of Nosema ceranae in Apis cerana

Frontiers in Insect Science
Background and aimsApis cerana is the native host of Nosema ceranae (N. ceranae). Previous studies reported that N. ceranae was more harmful to the new host (Apis mellifera) than the original host that had spread globally and become one of the factors ...

Dwelling in a post‐fallout landscape: re‐shaping and sustaining life in a former evacuation zone in Fukushima Habiter après la catastrophe : redonner forme au monde et entretenir la vie dans une ancienne zone évacuée à Fukushima

Journal of the Royal Anthropological Institute, EarlyView.
This article explores the activities of daily life in a village neighbouring the TEPCO nuclear power plant in Fukushima. It argues that one of the potentials of taking a dwelling perspective – a phenomenological approach to living within the ecological and social environments – emerges most compellingly within a polluted landscape.

Multi-agent decision-making dynamics inspired by honeybees [PDF]

, 2018
When choosing between candidate nest sites, a honeybee swarm reliably chooses the most valuable site and even when faced with the choice between near-equal value sites, it makes highly efficient decisions.

Insights on the nutritional ecology of a nocturnal pollinating insect

Insect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.

Rapid evolution of chemosensory receptor genes in a pair of sibling species of orchid bees (Apidae: Euglossini). [PDF]

, 2015
BackgroundInsects rely more on chemical signals (semiochemicals) than on any other sensory modality to find, identify, and choose mates. In most insects, pheromone production is typically regulated through biosynthetic pathways, whereas pheromone sensory

Molecular mechanisms of sex determination in Lepidoptera: current status and perspectives

Insect Science, EarlyView.
The genetic basis of sex determination in Lepidoptera was discovered in 2014 in the silkworm Bombyx mori. In this model species, the W chromosome‐derived small piRNA called Fem piRNA downregulates the expression of a Z‐linked gene, Masculinizer (Masc), which leads to the default female‐specific splicing of the doublesex gene (dsxF) and thus to female ...

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

Insect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.
