Chemoreceptor Evolution in Hymenoptera and Its Implications for the Evolution of Eusociality. [PDF]

, 2015
Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on the perception of social context mainly through pheromones, and chemoreceptors are hypothesized to have played important adaptive roles in the evolution of ...

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 ...

The dose makes the poison: have “field realistic” rates of exposure of bees to neonicotinoid insecticides been overestimated in laboratory studies? [PDF]

, 2014
Recent laboratory based studies have demonstrated adverse sub-lethal effects of neonicotinoid insecticides on honey bees and bumble bees, and these studies have been influential in leading to a European Union moratorium on the use of three neonicotinoids,

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.
