The efficacy of Steinernema feltiae in the control of Cydia pomonella in organic apple and pear orchards of Patagonia Argentina and its impact on local populations of entomopathogenic nematodes
Abstract
This study evaluates the efficacy of the commercial product, Steinernema feltiae (NEMAPOM, e-nema GmbH, Germany), in controlling diapausing Cydia pomonella (Linneaus) (Lepidoptera: Tortricidae) (codling moth; CM) larvae in commercial organic orchards of pome fruits and in harvest bins in Rio Negro Valley, Argentina, subject to the attack of this pest. The infectivity of S. feltiae at
different temperatures in the laboratory and the persistence in the

This study evaluates the efficacy of the commercial product, Steinernema feltiae (NEMAPOM, e-nema GmbH, Germany), in controlling diapausing Cydia pomonella (Linneaus) (Lepidoptera: Tortricidae) (codling moth; CM) larvae in commercial organic orchards of pome fruits and in harvest bins in Rio Negro Valley, Argentina, subject to the attack of this pest. The infectivity of S. feltiae at
different temperatures in the laboratory and the persistence in the field of this commercial product and of local entomopathogenic nematode (EPN) strains after application were determined. The field assay was carried out in winter, with an application dose
of 1.5 billion infective juveniles (IJs) ha−1 on a total surface of 0.5 ha. Mortality by S. feltiae in CM larvae was greater than 85% at two of the four test sites
