Evaluating astigmatid mites as alternative diets for Orius laevigatus: Effects on life history parameters
Full text linkIntegrated pest management (IPM) in greenhouse cultivation has benefited significantly from the use of predators such as Orius laevigatus. This beneficial insect, a natural enemy of thrips, can feed on pollen, facilitating preventive releases in flowering crops. However, in the absence of quality pollen, a supplementary food source is required to facilitate establishment. This study compared the performance of different populations of O. laevigatus, including wild and commercial populations and selected strains adapted to suboptimal pollen diets (1POL and 2POL), all fed with various species of astigmatid mites, a more economical alternative to traditional foods like Ephestia kuehniella eggs and Artemia cysts. The selected strains of O. laevigatus exhibited higher survival during nymphal development and greater fecundity when fed astigmatid mites compared to commercial populations. Among the astigmatid mites, Acarus siro was the best-performing diet, supporting high survival and acceptable development; however, it did not match the fecundity obtained with Ephestia kuehniella eggs. Acarus siro therefore represents a cost-effective supplementary or maintenance food, particularly suitable for sustaining populations in crops and for reducing reliance on Ephestia, especially when using genetically selected O. laevigatus strains that show enhanced performance on suboptimal diets.This research was funded by Grant PID2020-116897RB-I00 and PID2024-155785OB-I00 funded by MICIU/AEI/10.13039/501100011033.

Influence of melatonin and salinity on salicornia spp yield and shelf life
No full text[SPA] La salicornia es una planta halófita destacada por sus múltiples beneficios, tanto para el consumo humano, como sustituto a la sal convencional, como para otros muchos ámbitos, entre los más destacados, la recuperación de suelos afectados por niveles altos de salinidad. En este trabajo se ha estudiado su cultivo en condiciones salinas bajo aplicaciones de melatonina para mejorar su productividad.
En este proyecto, se evaluó el comportamiento del cultivo Salicornia spp. a diferentes niveles de salinidad (0-50-100-200 mM de NaCl) y cuatro concentraciones de melatonina exógena (0-50-100 y 200 μM) aplicadas de manera foliar. El experimento se llevó a cabo mediante un sistema de bandejas flotantes bajo condiciones de invernadero.
Tras finalizar el cultivo, se evaluaron los parámetros de rendimiento, crecimiento y comportamiento post cosecha. Los resultados indican que la alta salinidad, combinada con dosis moderadas de melatonina, desempeña un papel relevante en el rendimiento y la acumulación de biomasa, especialmente en la biomasa radicular y la altura de las plantas. La aplicación exógena de melatonina favoreció además la conservación y calidad de los brotes en post cosecha. Aunque en las condiciones estudiadas no se observó un efecto directo sobre el incremento del rendimiento, su uso junto con niveles moderados de salinidad mostró una influencia positiva al mejorar la tolerancia al estrés salino y el comportamiento post cosecha del cultivo.
[ENG] Salicornia is a halophytic plant noted for its multiple benefits, ranging from human consumption as a functional substitute for conventional salt and for several other applications, most notably the rehabilitation of soils affected by high salinity levels. To optimize its cultivation and productivity, this study investigated whether the exogenous application of melatonin could enhance growth and yield performance.
The behaviour of Salicornia spp. was studied at different levels of salinity (0-50-100- 200 mM NaCl) combined with different melatonin concentrations (0-50-100 and 200 μM) The plant completed their reproductive cycle in a floating system under greenhouse conditions.
After completing their growth cycle, the yield, growth and post-harvest behaviour parameters of Salicornia spp. were evaluated. Results indicate that high salinity, combined with moderate doses of melatonin, plays a significant role in yield and biomass accumulation, especially in root biomass and plant height. Furthermore, exogenous application of melatonin also favoured the preservation and quality of shoots after harvest. Although no direct effect on yield increase was observed under the conditions studied, the synergistic use of melatonin with moderate salinity levels positively influenced the crop by improving salt stress tolerance and post-harvest behaviour of the crop.Escuela Técnica Superior de Ingeniería AgronómicaUniversidad Politécnica de Cartagen
