Adhesion to nematodes of conidia from the nematophagous fungus Drechmeria
Conidia of the endoparasitic nematophagous fungus Drechmeria coniospora adhere to the sensory organs of many nematode species. In some cases the adhesion phase is followed by penetration of the nematode cuticle and subsequent infection. In a study of eight different nematode species and five strains of the fungus only two species were infected: Panagrellus vedivivus was infeted by all strains a...
متن کاملSusceptibility of Neoaplectana spp. and Heterorhabditis heliothidis to the Endoparasitic Fungus Drechmeria coniospora.
Adhesive conidia of the nematophagous fungus, Drechmeria coniospora (Drechsler) W. Gams and Jansson (Moniliales: Deuteromycetes), would occasionally attach but never penetrate the infective stages of insect parasitic Neoaplectana carpocapsae, N. glaseri, N. bibionis, N. intermedia, and Heterorhabditis helfothidis (Rhabditida). However, adult and pre-infective stages of Neoaplectana spp. became ...
متن کاملControl of Root-Knot Nematodes on Tomato by the Endoparasitic Fungus Meria coniospora.
The endoparasitic nematophagous fungus Meria coniospora reduced root-knot nematode galling on tomatoes in greenhouse pot trials. The fungus was introduced to pots by addition of conidia at several inoculum levels directly to the soil or addition of nematodes infected with M. coniospora to the soil; both methods reduced root galling by root-knot nematodes. These studies represent a part of a rec...
متن کاملLoss of Virulence of the Endoparasitic Fungus Drechmeria coniospora in Culture.
Parasitic fungi in culture frequently lose pathogenicity. For example, the virulence of certain entomogenous fungi decreases during in vitro culture over long time periods (12). Virulence of fungal isolates has been restored by serial passage of the organism th rough the insect host (13), through mutagenesis by ionizing radiations (1), and by genetic manipulation. In an overview of random genet...
متن کاملComparative genomic analysis of Drechmeria coniospora reveals core and specific genetic requirements for fungal endoparisitism of nematodes
Drechmeria coniospora is an obligate fungal pathogen that infects nematodes via the adhesion of specialized spores to the host cuticle. D. coniospora is frequently found associated with Caenorhabditis elegans in environmental samples. It is used in the study of the nematode’s response to fungal infection. Full understanding of this bi-partite interaction requires knowledge of the pathogen’s gen...
