“…It has been suggested that volatile compounds such as α-pinene, β-pinene, and 1-hexanol may attract L. dispar towards Larix gmelinii Rupr. [20] and that terpenoids influence patterns of L. dispar grazing on Quercus ilex L. [21].…”

The cork tree, Quercus suber L., is a characteristic species of the Dehesa agrosilvopastoral system, typical of western Spain. Defoliating insects are an important component of these ecosystems. This study assessed the presence and impact of defoliators feeding on Q. suber soft leaf tissue and their relationship with foliar monoterpene emission profiles. Samplings consisted of weekly tree beating (15 times per tree per sample) during the flight period of key species. We studied 26 cork trees with known profiles of foliar monoterpene emission (13 pinene and 13 limonene chemotypes). We identified a total of 272 larvae from 9 species. The main species were Catocala nymphagoga Esper (40.8%) and Periclista andrei Know (27.6%). Notably, 70.6% of larvae were found on trees with a pinene chemotype. The combined abundance of the four key defoliator species (C. nymphagoga L., P. andrei, Bena bicolorana L., and Cyclophora punctaria L.) was 62.7% lower on limonene-chemotype trees than pinene-chemotype trees. Significant differences were found in defoliation damage between leaves with distinct terpene emission profiles. These results suggest that both the abundance and damage caused by defoliators differ with trees’ emission profiles, and this may indicate differences in palatability and/or nutritional quality between Q. suber trees with distinct foliar monoterpene emission profiles.

En este trabajo se estudió la presencia de insectos defoliadores de hoja tierna (dentro de los órdenes Lepidoptera e Hymenoptera), en una dehesa de Quercus suber en Huelva (TM Almonte), y su relación con los perfiles de emisión foliar de monoterpenos de los árboles. Los muestreos consistieron en vareos semanales (15 golpes por árbol y vareo) entre el 28/3/2019 y el 10/5/2019 (comprendiendo el vuelo de las principales especies en la zona estudiada). Se estudiaron 25 alcornoques cuyo perfil de emisión de monoterpenos foliares era conocido previamente (12 con perfil tipo pineno, 13 con perfil tipo limoneno). Se identificaron un total de 272 larvas pertenecientes a 9 especies. Las especies dominantes fueron Catocala nymphagoga (40.8 %) y Periclista andrei (27.6%); junto a ellas se encontraron Bena bicolorana, Syntaurucus pirithous, Drepana uncinula, Archyps xylosteana, Cyclophora punctaria, Satyrium esculi y Lasiocampa trifolii. El 70.6 % de las larvas se encontró en árboles con perfil tipo pineno, y un 29.4 % en árboles de perfil tipo limoneno. La composición en especies resultó diferente entre árboles de distinto perfil emisor. Mientras que L. trifolii y S. pirithous no se encontraron en árboles de perfil limoneno (escasas en tipo pineno), D. uncinula y A. xylosteanus tuvieron abundancia ligeramente mayor para el perfil tipo limoneno. La presencia conjunta de las cuatro especies más relevantes (C. nymphagoga, P. andrei, B. bicolorana y C. punctaria) resultó un 62.7% menor en árboles con perfil tipo limoneno que en árboles de tipo pineno.

Exploring the Effects of Plant Odors, from Tree Species of Differing Host Quality, on the Response of Lymantria dispar Males to Female Sex Pheromones

et al. 2017

A widely accepted hypothesis for host-plant selection in herbivorous insects is that ovipositing females select host-plants that maximize the survival and performance of their offspring. However, numerous studies indicate that this is not always the case for polyphagous species. Lymantria dispar is a highly polyphagous forest defoliator and has flightless females in some subspecies, resulting in a limited capacity to make host-choices. Males of other Lepidopteran species utilize a combination of sexual pheromones and plant volatiles in their mating choices and exhibit preferences among plant species. We explored the behavior of L. dispar males towards sexual pheromone in the presence and absence of plant volatiles and their ability to discriminate between two plant species with different degrees of suitability for their offspring: a suboptimal host (Pinus sylvestris), and an optimal host (Quercus robur). In no-choice wind tunnel assays, we found that rates of male success in locating a pheromone source were not altered by the presence of plant odors; however, the time spent by males searching for the pheromone source after reaching the full length of the tunnel was reduced by more than 50% in the presence of plant volatiles. In dual choice assays, males exhibited a clear preference for a combination of pheromones and plant volatiles over the pheromone alone. However, we did not find evidence of an innate ability to discriminate between the odors of optimal and suboptimal host plants. We discuss possible ecological and evolutionary explanations for these observations.
