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.

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.

Forager bees (Apis mellifera) highly express immune and detoxification genes in tissues associated with nectar processing. [PDF]
, 2015 Pollinators, including honey bees, routinely encounter potentially harmful microorganisms and phytochemicals during foraging. However, the mechanisms by which honey bees manage these potential threats are poorly understood.

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.

Glyphosate-Based Herbicides and Their Potential Impact on the Microbiota of Social Bees
ToxicsBee pollination is essential for terrestrial ecosystems and crop production. However, the species richness of wild bees and other pollinators has declined over the past 50 years, with some species experiencing dramatic decreases.

Integrative Zoology, EarlyView.This study examines the ecophysiological responses of common waxbills to temperature variation in Portugal. We measured body condition and basal metabolic rate (BMR) during summer and winter across two regions in Portugal. Body condition was negatively correlated with temperature, while the relationship between BMR and temperature varied seasonally. In
