Ancylis tineana moth

Systematic position: Ancylis tineana belongs to the order Lepidoptera, family Tortricidae. Known as a leafroller, this moth is a common pest in various orchards, often overlooked until significant leaf damage becomes visible.

Host plants: The primary hosts are fruit trees from the Rosaceae family, including apple, pear, and cherry trees. The pest is also capable of feeding on various deciduous shrubs, making it highly adaptable to different landscapes and garden environments.

Biology and life cycle: The life cycle is typical for Tortricidae moths, consisting of egg, larval, pupal, and adult stages. Larvae typically overwinter in cocoons under tree bark or among leaf litter. Once temperatures rise in spring, the adults emerge, mate, and deposit eggs on the foliage, starting a new cycle of development.

Damage and economic impact: The larvae are responsible for the damage, as they feed on leaves by rolling them and binding them with silk threads. This feeding pattern causes the leaves to curl, yellow, and eventually die. Heavy infestations can lead to substantial defoliation, which stresses the trees and reduces their photosynthetic capacity for the entire season.

Control measures: Managing Ancylis tineana requires a proactive approach to reduce population levels before they cause economic damage:

• Mechanical removal of infested leaves and rolled nests during the early season.
• Application of dormant oil sprays to target overwintering larvae in bark crevices.
• Using pheromone traps to monitor adult flight and time insecticide applications precisely.
• Implementing biological control by encouraging natural predators such as parasitic wasps and birds.
• Chemical control with selective insecticides during the larval hatching period to minimize impact on beneficial insects.
