Soil-Borne Entomopathogenic Bacteria and Fungi [PDF]

Sustainability in Plant and Crop Protection, 2019
Being rich in microorganisms, the soil is an ideal environment and important reservoir for harvesting various types of beneficial microorganisms. Soil-borne entomopathogenic bacteria and fungi have been regularly isolated around the world to support crop producer in the never-ending arms race of pest management.

In vitro study on the nematicidal activity of entomopathogenic bacteria against the root knot nematode Meloidogyne incognita

Journal of Applied and Natural Science, 2022
National loss of Rs. 21,068.73 million has been estimated due to plant-parasitic nematodes in India. Among plant-parasitic nematodes, one of the major nematodes, root-knot nematodes (RKNs), are well-known diseases causing major losses in vegetable crops.

Isolation and Characterization of Photorhabdus Spp. (Enterobacteriaceae) Isolated From Heterorhabditis Bacteriophora in Kashere, Nigeria

Journal of Applied Sciences and Environmental Management, 2021
Photorhabdus bacteria are symbiotically associated with the infective juveniles of entomopathogenic nematodes of the genus Heterorhabditis. These bacteria after infecting a susceptible host, produces a host of lethal toxins that killthe insect hosts ...

Regulating Alternative Lifestyles in Entomopathogenic Bacteria [PDF]

Current Biology, 2010
Bacteria belonging to the genera Photorhabdus and Xenorhabdus participate in a trilateral symbiosis in which they enable their nematode hosts to parasitize insect larvae. The bacteria switch from persisting peacefully in a nematode's digestive tract to a lifestyle in which pathways to produce insecticidal toxins, degrading enzymes to digest the insect ...
