| Sumario: | Nematodes of the Meloidogyne genus
affect to most of crops of an economic
importance in Argentina. Researches related
to new control strategies are needed to
reduce the damage produced by these
organisms. The objective of this work was
to compare the effects of Galleria mellonella
cadavers infected with the Argentine isolates
Heterorhabditis bacteriophora Rama Caída
and Steinernema rarum NOE, cadaver
macerates and dead infective juveniles (IJs)
on M. javanica suppression. Experiments
were performed using 24-well plates and
pepper plants grown in a growth chamber.
The entomopathogenic nematodes-infected
G. mellonella cadavers, their cadaver
macerates and dead IJs were effective
in suppressing M. javanica second-stage
juveniles under laboratory conditions. The use
of H. bacteriophora-infected cadavers caused
a significant decrease in the number of galls
and egg masses on pepper plants parasitized
by M. javanica, in a growth-chamber. |
