DNA differences found between Africanized and European honeybees. [PDF]
The harmful en masse introduction of Africanized honeybees into the United States will occur within 5 years. Possible means of control are dependent on a reliable way to distinguish the Africanized bees from the extant European bees. Current means of identification are inadequate.

Lords of the flies: dipteran migrants are diverse, abundant and ecologically important
ABSTRACT Insect migrants are hugely abundant, with recent studies identifying the megadiverse order Diptera as the major component of many migratory assemblages. Despite this, their migratory behaviour has been widely overlooked in favour of more ‘charismatic’ migrant insects such as butterflies, dragonflies, and moths.

Abstract Quantitative real‐time polymerase chain reaction (qPCR) is a method widely used to determine changes and differences in gene expression. As target gene expression is most often quantified relative to the expression of reference genes, the validation of suitable reference genes is of critical importance.

Social immunity in honeybees-Density dependence, diet, and body mass trade-offs [PDF]
Group living is favorable to pathogen spread due to the increased risk of disease transmission among individuals. Similar to individual immune defenses, social immunity, that is antiparasite defenses mounted for the benefit of individuals other than the ...
