Entomopathogenic nematodes of the species Steinernema feltia are a biological control agents used to control fungus gnats,shoreflies and thrips.This agent is ideal to quickly controlling moderate pest infestations.
Entomopathogenic nematodes are distributed in the juvenile stage (infectious larvae). There are 0,4 to 1,5 mm long and can be observed with a 20 X magnifying glass. Once in the soil, they penetrate in the insect pest by its natural openings (mouth, respiratory orifices and anus). The Nematodes feed on the tissues and release symbiotic bacteria that are present in their intestines. These bacteria kill the host after 24 to 48 hours.
The majority of sciarid species feed on decomposing algae and on organic matter. On the other hand, some species of the Bradysia genus prefer to feed on living plant tissues or mushroom tissues. They cause significant growth problems and promote the spread of fungal diseases such as Pythium, Fusarium and Rhizoctonia.
