Primer registro de Rosalia alpina (Linnaeus 1758) (Coleoptera, Cerambycidae) en Prunus avium (L.) (Rosaceae)

The use of Prunus avium (L.) as habitat of the legally protected longicorn Rosalia alpina (Linnaeus, 1758) is recorded for the first time. The observations took place in a dying cherry tree located in a garden of a countryside land belonging to the municipality of Asteasu (Gipuzkoa). The presence of adults mating and looking for oviposition sites, exit holes, and one larva inside a dead branch suggest that R. alpina is able to complete its life cycle in the cherry tree. Two other saproxylic species, Cerambyx scopolii Fuessly, 1775 and Ampedus pomonae (Stephens, 1820), were found inside dead branches. In the region of the study area, R. alpina had only been previously recorded on Fagus sylvatica L. trees. Therefore, further research is suggested to determine the importance of other tree species like alternative habitat and their role in the conservation of R. alpina.El empleo de Prunus avium (L.) como hábitat para el longicornio legalmente protegido Rosalia alpina (Linnaeus, 1758) se registra por primera vez. Las observaciones tuvieron lugar en un cerezo moribundo localizado en un jardín en un entorno rural perteneciente al término municipal de Asteasu (Gipuzkoa). La presencia de adultos apareándose y buscando lugares para ovopositar, de orificios de salida y de una larva dentro de una rama muerta, sugieren que la especie es capaz de completar su ciclo biológico en el cerezo. Dentro de las ramas muertas se encontraron otras dos especies de saproxílicos: Cerambyx scopolii Fuessly, 1775 and Ampedus pomonae (Stephens, 1820). En la región del área de estudio, R. alpina sólo había sido previamente citada en ejemplares de Fagus sylvatica L. Por tanto, se recomiendan futuras investigaciones para determinar la importancia de otras especies de árboles como hábitat alternativo y su papel para la conservación de R. alpina

Effectiveness and tolerability of a squalane and dimethicone-based treatment for head lice

Head lice (Pediculus humanus capitis) are worldwide obligate human ectoparasites, with high implications in pediatrics. In Europe, first-line topical neurotoxic insecticidal therapeutic strategies are being replaced by topical physically acting agents as the first-choice treatment. Safety of the active ingredients and high efficacy in a one-time single-dose treatment with a brief treatment application time are key issues for consumer use and effective compliance. The aim of this study was to assess the in vitro efficacy of a newly developed squalane and dimethicone-based pediculicidal formula, against motile head lice and eggs after 2 and 5 min immersion in the product, as well as its skin tolerance and acceptability under dermatological and pediatric expert control in children with atopic skin. The results indicate that at both time points, 100% mortality rate of head lice crawling stages and latest age eggs was achieved. The formula was well tolerated and suitable for children with atopic skin from 12 months of age. Showing high in vitro efficacy and good skin acceptability, this solution is presented as a new safe alternative therapy for treatment of head lice infestations.This work was funded by Ferrer International S.A., the company that developed the human head louse treatment discussed in this paper.
