Other methods for controlling fungus gnats include drenching the soil annually in an insecticidal soap. Hydrogen peroxide can be mixed with water and used to kill fungus gnat larvae in infected soil with a mixture of one part 3% hydrogen peroxide mixed with four parts water, then applied to the soil.
Gnat from Robert Hooke's Micrographia, 1665 A female black fungus gnat. A gnat (/ ˈ n æ t /) is any of many species of tiny flying insects in the dipterid suborder Nematocera, especially those in the families Mycetophilidae, Anisopodidae and Sciaridae. [1] Most often they fly in large numbers, called clouds.
The life cycle of only a few species has been studied in any detail, mainly those which are pests of commercially grown mushrooms. Sciarid larvae often occur in decaying plant matter such as rotten wood or under the bark of fallen trees, but can also be found in animal feces or fungi. [2]
Fungus gnats are a common pest among houseplants.These small flies tend to go unnoticed at first, slowly building their populations by laying eggs on the soil of our container plants.
Arachnocampa is a genus of nine fungus gnat species which have a bioluminescent larval stage, akin to the larval stage of glowworm beetles. The species of Arachnocampa are endemic to Australia and New Zealand, dwelling in caves and grottos, or sheltered places in forests. A previous placement was in the genus Bolitophila.
Mycetophilidae is a family of small flies, forming the bulk of those species known as fungus gnats. About 3000 described species are placed in 150 genera, but the true number of species is undoubtedly much higher. They are generally found in the damp habitats favoured by their host fungi and sometimes form dense swarms. [1]
Bradysia is a genus of fungus gnat in the family Sciaridae. [3] [4] They are commonly known as darkwinged fungus gnats. [3]They are considered a major pest in greenhouse agriculture because they thrive in the moist conditions common inside greenhouses and feed on the plants being grown within. [5]
The larvae eat fungus spores which grow upon the webbing to sustain themselves, mainly from saprophytic species of fungus that feed on decaying plant matter. [2] The webbing built by the larvae likely also provides a protective environment against predators as larvae have been observed retreating when the webbing is suddenly vibrated. [ 2 ]
