fungus gnat larvae

Bti is also used to control fungus gnat larvae in greenhouse ornamental plants.

In addition to the yellow sticky traps, potato disks can be used to monitor fungus gnat larvae.

A spray or drench application of insecticides to control other pests may also control fungus gnat larvae and adults.

The bacterial insecticide Bacillus thuringiensis var. israelensis can be applied as a soil drench for control of fungus gnat larvae.

Sporangia and zoospores spread easily in re-circulating water and are also spread by fungus gnat larvae, which are attracted to rotted roots.

Fungus gnat larvae have been shown to vector fungal stem and root pathogens including Pythium, Fusarium and Phytophthora.

Fungus gnat larvae may be suppressed by predatory nematodes (Heterorhabditis spp., Steinernema feltiae) or a predatory mite (Hypoaspis miles), but predators alone do not provide commercially acceptable control in greenhouse lettuce.
