EFFECT ON GROWTH AND ROOT NODULATION OF CLOVERS, TRIFOLIUM SPP., BY GALLERIA MELLONELLA (L) (LEPIDOPTERA, PYRALIDAE) INFECTED WITH STEINERNEMA CARPOCAPSAE (WEISER) (RHABDITA, STEINERNEMATIDAE) AND ITS SYMBIONT, XENORHABDUS NEMATOPHILUS POINAR AND THO

摘要

Red and white clovers, Trifolium spp., were grown in nitrogen-poor soil containing cadavers of larval Galleria mellonella (L.) that were infected with Steinernema carpocapsae (Weiser) and its symbiont Xenorhabdus nematophilus Poinar and Thomas. Growth and root nodulation were not affected by the nematode treatment, leading us to conclude that they would not be impaired through the action of antimicrobial agents produced by Xenorhabdus spp. present in soils because of Xenorhabdus-infected insect cadavers.
