ABSTRACT: Entomopathogenic nematodes are obligate insect parasitoids having a free living third juvenile infective stage that penetrates the insect host, killing it within 24-48 hours, thus being highly effective as bioinsecticides. Studies were carried out in Europe to test their efficiency to control several insect pests affecting chestnut fruit, such as curculionids and tortricids. The main aim of. this work is to detect the occurrence of entomopathogenic nematodes in chestnut soil with the aim to carry out a biological control programme against Curculio elephas and Cydia sp., pests causing the most important damage on chestnut in Galicia. Samples were taken in 30 chestnut stands in our region, determining those entomopatogenic nematodes present, by using bait traps with Galleria mellonella (Lepidóptero: Pyralidae) larvae (Bedding e Akhurst, 1975). So far, nematodes belonging to the genus Steinernema and Heterorhabditis were detected in various surveyed stands by morphological and morphometric analysis and molecular techniques Keywords: Steinernema, Heterorhabditis, identification, pests, biological control |
