The Agri-Food and Biosciences Institute (AFBI) have issued a plant and human health warning due to oak processionary moth being found recently in Dublin on planted oak trees imported from Belgium.
Whilst the adult is a grey-ish non-descript moth, it is the caterpillars that give the moth its name and present a risk to both plant and human health.The oak processionary moths live almost exclusively on oak trees and the caterpillars form communal webbed nests on the trunks and branches of the tree. Caterpillars feed on the oak leaves during the night and shelter in the nest during the day.
The recent finding in Dublin is the first on the island of Ireland. However, oak processionary moth has been well established in London since 2006. It is managed in London through the use of insecticides with an overall cost of £1.2 million per annum including surveillance work and public health notifications. It is a difficult pest to control as the caterpillar nests are often high up in the tree canopy, therefore it is important that we prevent oak processionary moth from establishing in the first place.
The caterpillar nest in Dublin has been eradicated but the risk remains. Please be vigilant for this unwanted invader.
