  Amorph Blues/ fungus gnats
From: Dan Levin <levin at pixar.com> on 2004.07.06 at 15:22:45(11724)

Thanks for adding a new/ thoughtful dimension to the fray. I've no
doubt that fungus gnat larvae absolutely engage both as the primary
invader and as a vector for fungal infection in many cases. Fungus
gnats are, in my opinion, an insidious pest generally underestimated/
overlooked by hobbyist growers. This is a mistake- considering the
potential for serious damage by the largely unseen larval stages.

I still hold by my observation (pestilent postulate?) that in my modest
greenhouse anyway, rotting conditions invite fungus gnat larvae to
infect otherwise dormant araceous tubers and corms. The areas of
rot are consistently too pronounced & developed, and the number of
embedded larvae too few (generally just one or two) when problems
are first detected. But who knows - I could absolutely be wrong..!
