“… Sterling and Speight (1989) describe populations in England as being primarily limited to the southeast coast in periods between outbreaks, but spreading inland during periods of population increases. Populations that primarily persist or are more severe in coastal habitats have also been reported in the Netherlands ( Moraal and Jagers op Akkerhuis 2011 ) and Spain ( Frago et al 2011 ), though there are many areas in continental Europe where browntail moth distribution is not predominantly coastal ( Sterling and Speight 1989 ). We did not see a relationship between distance from the coast and abundance of browntail moth life stages during its current outbreak in Maine, although distance from Peaks Island which has supported persistent populations since at least the 1970s, was a significant predictor of the rank density of overwintering hibernacula.…”

“…We examined many larvae microscopically and saw no indication of microsporidia presence in live or dead caterpillars in Maine. Although Frago et al (2011) recognized that some unexplained mortality was likely due to pathogen infections, pathogens were not identified and quantified in their study. Entomophaga aulicae is globally distributed and has been reported attacking lepidopteran hosts in the United Kingdom, France, the Netherlands, Germany, and Russia ( Gama 2018 ).…”

“…4 ). Sterling and Speight (1989) and Frago et al (2011 , 2012 ) conducted surveys and evaluated the impacts of natural enemies of browntail in Europe. They both reported a number of different parasitoid species, and Sterling and Speight (1989) identified microsporidia and virus infections in England, attributing microsporidia as a key factor responsible for most of the variation in mortality between sites.…”

“…In some parts of its range, most notably England, France, and Germany, its recorded to cause frequent damage to orchards, shade trees, and flowering shrubs and plants ( Fernald and Kirkland 1903 , Sterling and Speight 1989 ). Occasional, localized outbreaks of browntail moth have occurred in southern England ( Sterling and Speight 1989 ) and periodic outbreaks have been reported in oak forests in Hungary ( Leskó et al 1995 ) Bulgaria ( Pilarska et al 2002 ), and Iran ( Arefipour et al 2005 ), and on the evergreen shrub, Arbutus unedo, in Spain ( Frago et al (2011) , as well. As in its introduced range, the cause of browntail moth populations fluctuations in its native range is unclear, though the scale of outbreaks is generally smaller than what was and is being experienced currently in the northeastern U.S.…”

The browntail moth (Euproctis chrysorrhoea (L.)) is a forest pest that was accidentally introduced in the late 1800’s and spread throughout New England in the early part of the 20th Century. At its peak range expansion in 1915 it encompassed an area of 150,000 km2 after which populations declined. By the 1960s, its distribution had receded to relic populations on outer Cape Cod, MA, and islands in Casco Bay, ME. In 1989 browntail moth resurged in Maine, with periodic, moderate outbreaks before a dramatic increase of the population occurred in 2016. We examined the pattern of annual defoliation by browntail moth since its resurgence in the 1990s as well as variation in populations throughout infested areas in Maine during three years of the recent outbreak, 2016–2018, relative to differences in weather, parasitism and habitat characteristics. Levels of defoliation over 24 yr were predicted by the preceding spring precipitation (−, negative effect) and the year’s previous late summer and early fall temperatures (+, positive effect) when first to third instar larvae feed and then construct winter hibernacula. Late summer temperatures predicted the abundance of hibernacula across outbreak areas (+). Early spring temperatures (+) and early and late spring precipitation (−) predicted early summer larval and pupal nest abundance. Warmer fall temperatures result in more mature populations coming out of winter hibernacula in the spring, whereas spring precipitation drives epizootic outbreaks of Entomophaga aulicae (Reichardt in Bail) Humber (Entomophthorales: Entomophthoraceae). with parasitoids playing a lesser role. Climate trends indicate continued increases in fall temperatures since browntail moth resurgence.

“…It is a univoltine, solitary species that overwinters as a first instar and adults emerge in July. Although extensive information about its dynamics is lacking, parasitoids appear to play a key role in its dynamics (Elkinton, Preisser, Boettner, & Parry, 2008;Frago, Pujade-Villar, Guara, & Selfa, 2011).…”

Transient synchrony among populations of five foliage‐feeding Lepidoptera

Studies of transient population dynamics have largely focused on temporal changes in dynamical behaviour, such as the transition between periods of stability and instability. This study explores a related dynamic pattern, namely transient synchrony during a 49-year period among populations of five sympatric species of forest insects that share host tree resources. The long time series allows a more comprehensive exploration of transient synchrony patterns than most previous studies. Considerable variation existed in the dynamics of individual species, ranging from periodic to aperiodic. We used time-averaged methods to investigate long-term patterns of synchrony and time-localized methods to detect transient synchrony. We investigated transient patterns of synchrony between species and related these to the species' varying density dependence structures; even species with very different density dependence exhibited at least temporary periods of synchrony. Observed periods of interspecific synchrony may arise from interactions with host trees (e.g., induced host defences), interactions with shared natural enemies or shared impacts of environmental stochasticity. The transient nature of synchrony observed here raises questions both about the identity of synchronizing mechanisms and how these mechanisms interact with the endogenous dynamics of each species. We conclude that these patterns are the result of interspecific interactions that act only temporarily to synchronize populations, after which differences in the endogenous population dynamics among the species acts to desynchronize their dynamics.

One of the most significant categories of insect that cause damage to trees are the defoliators. While many orders of insects feed on tree foliage, in this chapter we will focus on Lepidoptera, as there are so many Lepidopteran larvae (caterpillars) that are known for their extensive tree damage. In this chapter we review the impact of foliage feeders on forest trees and stand composition, and the ways in which densities of these species or the defoliation they cause are monitored. We do not cover insects attacking ornamental trees in the landscape, nor do we cover insects feeding exclusively on foliage tips or buds.
