The impact of naturally occurring entomopathogenic nematodes on false codling moth, Thaumatotibia leucotreta (Lepidoptera: Tortricidae), in citrus orchards

The impact of naturally occurring entomopathogenic nematodes (EPNs) on Thaumatotibia leucotreta was studied in a citrus orchard in Nelspruit, South Africa. Fruit infestation by T. leucotreta was 58.6% lower (P < 0.05) in an orchard block where EPN was conserved compared to a block where EPN was suppressed by nematicide (cadusafos) application.
