Product Information

Taking various measures to improve efficacy is a crucial step to control subterranean insect pest via EPNs ( Labaude and Griffin, 2018; Oliveira-Hofman etal., 2019). To improve the efficiency of EPN against target insects, research has explored combining EPNs with entomopathogenic fungi ( Mc Namara etal., 2018), bacteria ( Jaffuel et al., 2019), or even certain chemical insecticides ( Viteri et al., 2018; Yan et al., 2019). However, the potential effect of combining EPN with abiotic approaches has rarely been reported. Controls: Predatory mites ( Hypoaspisand Ambyseius species) and mighty mite ( Macrocheles robustulus) can be used. The predatory bug Orius laevigatus is also sometimes available.The nematode biological control (containing Steinernema feltiae and S. carpocapsae) sold as Fruit and Vegetable Protection can be used indoors and outside.

They like moist soil so houseplants are ideal, particularly if overwatered or you have a lot of them. Media temperatures should be above 50° F but avoid applying when soil temperatures are above 80°F. Optimum media temperatures are between 60-70°F. Use a soil thermometer to monitor temperature.

Eradication more likely as works over a 2 week period where nematodes multiply until all the larvae are dead For indoor plants, the predatory mite Hypoaspis can be applied to the soil. The mites inhabit the just area under the soil surface where fungus gnats pupate.Another biological control agent is the soil-predatory mite, Hypoaspis miles. This mite completes its life cycle (egg to adult) in 7 to 11 days. It normally inhabits the top layers of the growing medium, where it feeds on fungus gnat larvae. For best efficiency introduce it at planting or just afterward. Fungus gnats (or sciarid flies) are the little flying bugs around your plant. They look like small, pale flies with translucent wings that are slow fliers and don’t make an audible buzzing sound. Fungus gnat larvae damage plants by feeding on plant roots. They are especially destructive to seedlings and young plants, but can also damage mature plants if numbers are high. Larvae can tunnel into succulent stems at and below the growing medium surface. This tunneling collapses the stem causing the plant to wilt, or grow less vigorously. Larvae are capable of transmitting fungal pathogens such as Pythium, Thielaviopsis, and Fusarium. In addition, larval feeding creates wounds that allow secondary soil-borne pathogens to enter roots. Adult fungus gnats are also capable of transmitting fungal pathogens, including Botrytis. In addition to damaging plants, fungus gnat adults emerging from plants in wholesale or retail situations are considered a nuisance that can affect plant sales. Shore Flies Fungus gnats are major pests in ornamental plant propagation facilities; high organic matter content and moisture in the rooting media facilitate fungus gnat population growth and damage. Historically, propagation greenhouse managers rely on broad-spectrum insecticides, such as chlorpyrifos, to manage fungus gnats with varying degrees of success. Optimal management of fungus gnats must take an integrated approach due to the fungus gnats’ short life cycle, damage potential, and ability to take advantage of the humid condition in propagation greenhouses. An integrated pest management (IPM) program brings together multiple chemical and non-chemical control strategies to keep the fungus gnat population below damaging levels. The deployment of cultural and biological control tools also has the benefit of avoiding residual toxicity of some insecticides to biological control agents that growers may use during the finishing stage. The information in this publication will provide insight to growers and support the development of an integrated fungus gnat management program in propagation facilities. Description and Life Cycle

Nematode biological controls are usually either insect or mollusc specific. They therefore have the potential to infect non-target animals and so should be used in a targeted manner Marigolds make great bedding partners for carrots, celery, and onions to help keep invading species at bay. Alternatively, plant marigolds in your fallow soil — that will also keep the nematodes away. Any questions Water the growing media before and soon after application, but avoid over watering so they aren't washed out of the container. Sciarid fly (also known as compost fly) or Fungus Gnats are a common pest of greenhouse plants in the spring.Scout and record the number of fungus gnat and shore flies present before and after release of biological control agents in the greenhouse. This is why I advise you to switch to a non-organic potting mix for prevention to keep away fungus gnats. No soil, no problems. Bacillus thuringiensis subspecies israelensis ( Bti) is an entomopathogenic bacterium that infects only flies, including fungus gnats. Commercially available products include Gnatrol and can be applied to the media as a drench. The bacterium is only effective against larvae and will not kill pupae or adults. Fungus gnat larvae ingest the bacterial spores, and the bacteria infect and destroy the fungus gnats’ midguts. Bti does not reproduce or persist in the media, so regular reapplication is necessary. This bacterium should not be mixed with fertilizers or fungicides containing copper or chlorine, which can kill the bacterial spores. Chemical Control Steinernema feltiae are naturally occurring micro-scopic worms and predators of ants. Colonies of ants will not tolerate these predators in their nests.
