FREDERICTON (CNB) - Localized defoliation caused by the forest tent caterpillars has been observed in the Bathurst, Woodstock and Mactaquac areas.
Tent caterpillars are commonly referred to as armyworms because they congregate in large numbers. The species is native to New Brunswick and is one of most widespread defoliators of deciduous trees in Canada. Outbreaks occur every 10 to 12 years, with the last outbreaks in New Brunswick recorded from 1979 to 1984 and 1991 to 1996.
It is at the caterpillar stage when the pest feeds on the leaves of aspen and other hardwoods. Populations are controlled by predators, parasites and disease. These controls in nature have already been at work within localized areas, and there are no plans to conduct any spray program.
Caterpillars will soon complete their feeding and will form yellowish-white cocoons in which they will transform into adult moths.
Property owners within these areas can take a number of steps to reduce damage:
