Fungus gnats have been shown to transmit a variety of plant pathogenic fungi that produce aerial dispersal stages. However, few studies have examined potential interactions between fungus gnats and oomycetes, including Pythium spp. A series of laboratory experiments were conducted to determine if fungus gnat adults are vectors of several common greenhouse Pythium spp., including P. aphanidermatum, P. irregulare, and P. ultimum. An additional objective was to determine if P. aphanidermatum can be maintained transstadially in the gut of a fungus gnat larva through the pupal stadium to be transmitted by the subsequent adult. Adult fungus gnats did not pick up infectious Pythium propagules from diseased plants and transmit them to healthy plants in any experiment. Species-specific primers and a probe for real-time PCR were developed to detect the presence of P. aphanidermatum DNA in fungus gnat tissue samples. P. aphanidermatum DNA was detectable in the larval and pupal stages; however, none was detected in adult fungus gnats. These results are in agreement with previous studies that have suggested that adult fungus gnats are unlikely vectors of Pythium spp.

The transmission of infectious disease or pathogens. When transmission is within the same species, the mode can be horizontal or vertical (INFECTIOUS DISEASE TRANSMISSION, VERTICAL).
The transmission of infectious disease or pathogens from one generation to another. It includes transmission in utero or intrapartum by exposure to blood and secretions, and postpartum exposure via breastfeeding.
The transmission of infectious disease or pathogens from patients to health professionals or health care workers. It includes transmission via direct or indirect exposure to bacterial, fungal, parasitic, or viral agents.
