The role of Spulerina simploniella in the spread of chestnut blight
Forest Pathology 35 (4), 315-320
Abstract: The bark miner Spulerina simploniella (Lepidoptera: Gracilariidae) was found in coppice chestnut (Castanea sativa) forests in Greece but was not found in chestnut orchards. Its larvae mine under the thin periderm of young trees, 4-10 years old, while the stem bark is still smooth. Under normal conditions it does not cause any damage to the trees. However, when chestnut blight caused by Cryphonectria parasitica is present in the area, the insect may be an agent of disease spread. Experiments revealed that spraying of 23 pupation sites with a C. parasitica conidiospore suspension caused canker formation at a rate of 100% in the coppice chestnut forests of Mount Athos, North Greece. It is believed that rain during the pupation period (approximately May 23 to June 15) may deposit conidiospores on the freshly exposed phloem and cause cankers. This bark miner has been detected in several parts of Greece, however, always in intensively managed chestnut coppice forests.
