“…The Las Conchas Fire resulted in shifts in both communities, with statistically identifiable differences in burned versus unburned communities of both forest types. These results were similar to those of Chaundy-Smart et al (2012), who compared moth communities between clearcuts and burned stands in southern boreal forest dominated by Jack pine ( P. banksiana Lamb.) 5 yr after a wildfire.…”

Forest fires in North America are becoming larger in area and burning with higher severity as a result of climate change and land management practices. High-severity, stand-replacement fires can inflict major changes to forest insect communities, potentially extirpating many species through altered post-fire habitat resources. We assessed forest-dwelling macrolepidopteran moth communities in mixed conifer and ponderosa pine forests during the first year after the 2011 Las Conchas fire in New Mexico, USA. We deployed blacklight traps in replicated burned and unburned stands during June, July, and August in 2012. We collected 9,478 individuals, representing 211 species and 8 families. Noctuidae (124 species) and Geometridae (53) comprised the majority of the taxa, followed by Erebidae (21), Sphingidae (5), Notodontidae (3), Lasiocampidae (2), Saturniidae (2), and Drepanidae (1). Moth communities (species composition and abundances) in each forest type (mixed conifer vs. ponderosa pine) were statistically distinguishable, but shared 56.4% (119) of observed species. Overall, compared to unburned forests, post-fire moth communities in both forest types had significantly lower numbers of individuals, species richness and diversity, and lower evenness in ponderosa pine forests. As expected, categorizing moth taxa by larval host plant taxa revealed that reductions of moth populations following fire were associated with the elimination or reduction of available larval host plants (particularly conifers, oaks, and junipers). We predict that future moth community succession will likely parallel the overall transformation from a forested landscape to a montane meadow/grassland ecosystem, with continued reduction in tree-feeding species and increasing dominance by forb/grass-feeding species.

“…Despite their ubiquity in northern North American forests, assemblages of non-pest forest moths have not been extensively studied (Summerville and Crist 2008), and this is particularly true for the assemblages in boreal forest. Pohl et al (2004) characterised the moth community of an Alberta, Canada, mixed-wood boreal forest, and the effects on moth communities of mammalian herbivory (Brousseau et al 2013) and forest disturbance (Chaundy-Smart et al 2012) have been studied in boreal forests in eastern Canada. There have been no published studies of the implications of currently used spruce budworm control measures for the assemblages of non-target moths in boreal forests.…”

Effects of tebufenozide on the assemblage of moths (Lepidoptera) in an operational spruce budworm (Lepidoptera: Tortricidae) suppression programme

Tebufenozide (Mimic) kills Lepidoptera larvae that ingest it. Aerial applications of tebufenozide were made against spruce budworm (Choristoneura fumiferana (Clemens)) (Lepidoptera: Tortricidae) in boreal forest in Manitoba, Canada, in 1999 and 2000. In 2000 and 2001, moths in sprayed and unsprayed plots were sampled with light traps; trapping was supplemented by foliage sampling. Relative to unsprayed plots, catches of spruce budworm moths in plots sprayed in 1999 and 2000 were depressed in 2000, but not in 2001. Host tree defoliation was reduced in 2000 by 1999 and 2000 applications; the 2000 application reduced numbers of spruce budworm larvae in 2000 and 2001. Multivariate analysis revealed negative effects of tebufenozide application on two species of non-target moths in 2000 and no negative effects in 2001. Negatively affected species have larvae feeding in the tree canopy at the time of spray application. Higher catches of non-target species in sprayed treatments were observed for three species in 2000 and two species in 2001. We conclude that tebufenozide can depress the numbers of spruce budworm larvae and provide foliage protection during the year of application and the following year, and that negative effects on non-target species are detectable for about 15 months after application.

“…Such species may be lost from forest stands when this resource is removed. Coarse woody debris appears to be an important but little studied predictor of moth community composition in at least one temperate forest system (Chaundy‐Smart et al , ).…”

Effects of logging and coarse woody debris harvest on lepidopteran communities in the eastern deciduous forest of North America

1 Expansion of biomass energy production using woody feedstocks is being accomplished through post-timber harvest removal of coarse woody debris > 10 cm. The effect of this management on forest Lepidoptera is poorly known. 2 The present study aimed to determine whether forest lepidopteran diversity and species composition were affected by two silvicultural disturbances: timber harvest and post-logging removal of coarse woody debris > 10.0 cm in diameter. 3 In 2014, Lepidoptera were sampled from nine forest stands subject to one of three management treatments: control (no manipulation at all), clear cut and partial retention of coarse woody debris (80% removal), and clear cut and complete removal of coarse woody debris. 4 As expected, species richness and composition were significantly impacted by timber harvest. Subsequent removal of 80% or 100% coarse woody debris, however, did not affect specialists, detritivores and pollinators. 5 The absence of an effect as a result of the removal of coarse woody debris could be a result of the limited number of replicate stands, small stand size and the limited range of retention treatments. We suggest, however, that retention of fine woody debris with a diameter < 10.0 cm and inclusion of unlogged stands in the forest landscape maintains some of the habitat elements necessary for Lepidoptera.
