Entomopathogenic nematodes are strongly responding to such cues and I was wondering if other soil-dwelling insect pathogens would do so. I am therefore interested in studies showing if entomopathogenic fungi would grow towards their insect hosts or if entomopahtogenic bacteria would migrate towards insects. The cues involved in these potential attractions don't have to be identified, I rather look for a "proof of principle" that chemotaxis of soil-dwelling pathogens is not only restricted to nematode but can also be observed in other groups of organisms.
