Quarantine arthropod invasions in Europe: the role of climate, hosts and propagule pressure

Bacon, Steven J. ; Aebi, Alexandre ; Calanca, Pierluigi ; Bacher, Sven

In: Diversity and Distributions, 2014, vol. 20, no. 1, p. 84-89

Aim: To quantify the relative importance of propagule pressure, climate-matching and host availability for the invasion of agricultural pest arthropods in Europe and to forecast newly emerging pest species and European areas with the highest risk of arthropod invasion under current climate and a future climate scenario (A1F1).Location: Europe.Methods: We quantified propagule pressure,...

Architecture of the primary taste center of Drosophila melanogaster larvae

Colomb, Julien ; Grillenzoni, Nicola ; Ramaekers, Ariane ; Stocker, Reinhard F.

In: The Journal of Comparative Neurology, 2007, vol. 502, no. 5, p. 834-837

A simple nervous system combined with stereotypic behavioral responses to tastants, together with powerful genetic and molecular tools, have turned Drosophila larvae into a very promising model for studying gustatory coding. Using the Gal4/UAS system and confocal microscopy for visualizing gustatory afferents, we provide a description of the primary taste center in the larval central nervous...
