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.
Dear Dr. Hiltpold;
Sorry, i may be didn't understand well your question could be please explain more? are you asking about papers that study entomofungi against insects?
I wonder if the 'Galleria bait method' is helpful as the fungi are detected by their appearance on bait which implies they are able to find it though I don't know if the mechanism has been investigated http://onlinelibrary.wiley.com/doi/10.1111/j.1439-0418.1986.tb00912.x/abstract
Various methods are summarised and evaluated here which may be similarly relevant http://orgprints.org/11200/1/11200.pdf
Chemotaxis in zoosporic Fungi is known e.g. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3261367/
Good luck - I think this is a poorly understood area!

I have been working on entomopathogenic fungi but i isolate them from dead insects in the field "survey", i identify them by molecular tools then i use them again on alive insects with pathogenicity test. Fungi are present with different frequency they can be saprophyte or pathogen , a serie of experiences has to be done to confirm the pathogenicity of all isolates. The rest of methods where cited by Dr. David Hubble.
All the best
