“…N. alpina forests have been overexploited since the beginning of the 20th century, particularly in Chile, where most of its range has been converted to agricultural lands. Nowadays, the remaining natural forests are mainly under conservation plans and sustainable management, and the species is included in domestication programmes for productive and restoration purposes, both in Argentina and Chile (Gutierrez, 2003; Ipinza et al, 2000; Marchelli et al, 2021). As could be expected, N. alpina hosts a broad diversity and abundance of herbivorous insects, which feed on its leaves, seeds and stem, which may lead to a reduction in reproductive and photosynthetic rates, affecting the vigour and health of the trees (Carrillo & Cerda, 1987; Gentili & Gentili, 1988; McQuillan, 1993).…”

“…& Endl.) Oerst., commonly named Raulí is one of the most important native forestry species due to its excellent shape and timber quality (Donoso et al, 2004; Marchelli et al, 2021). In Argentina, this deciduous tree species has a restricted natural range, along the Andes Mountains (39°21′–40°35′S), covering 79,636 hectares in a narrow fringe of ca.…”

1. Genetic variation among host plants can influence herbivore behaviour and consequently their abundance, performance and environmental impact. In the Andean-Patagonian forest, the arboreal vegetation is dominated by species of genus Nothofagus. Previous studies of Nothofagus alpina demonstrated differences in genetic diversity among and within its populations. The native caterpillar Perzelia arda feeds on various Nothofagus sp.2. Our aim was to evaluate host selection behaviour of P. arda larvae towards different genetic pools of N. alpina trees.3. We collected leaf samples from trees growing in a common garden field trial and evaluated, by paired comparisons, not only differences among provenances but also variation between and within open pollinated families. 4. Our results demonstrated that P. arda performed a choice between the leaves of the host plants offered. This larva was able to choose specific provenances, open pollinated families and genotypes of N. alpina. 5.In conclusion, the larva is guided by characteristics of individuals and host plant species. These innovative results in insect-plant interaction studies demonstrate that it is important to evaluate discrimination between intra-specific hosts. Further study is required to fully understand the use of resources by this native insect, as well as the ecological consequences.
