Sciaria (fungus gnats)

Bradysia is the main genus encountered in the glasshouse.

Fungus gnats of the genus Bradysia differ from the Scatella fly in having a slender body, long legs, a sloping stance and shiny triangular wings. The larvae attack young or weakened plants.

They devour the rootlets and if the population grows very large may feed on the corm.

Biological control of the larvae by means of nematodes gives very good results.
