Parasite manipulation of host behaviour

RNA study tracks thousands of gene changes linked to worm's influence on earwigs' water-seeking behavior

Researchers at Otago, UBC and Brown report 673 earwig genes and 2,672 worm genes growing more active as a parasitic worm drives its host toward water. The RNA data give experimenters candidate genes in both species, though the paper stops short of showing which ones make the earwig seek water.
