“…These extend linear modelling by allowing for nonlinear relationships between the response variable and selected predictors using smooth functions (Wood, ). We used this feature to model response variables as a function of time due to the nonlinear relationship expected in temporal distributions of arthropod abundance and diversity over time (Porcel, Cotes, Castro, & Campos, ). GAMMs included time (week) as a smooth function fit using a penalized regression spline approach with smoothing estimated by cross‐validation.…”

Intensive agricultural management negatively affects both natural enemies of pests and pollinators. Such management also has the potential to adversely affect the ecosystem services that these communities confer. Organic management has been proposed as an alternative method to mitigate such problems by restoring the services provided by arthropod communities. We evaluated the effect of organic management on two ecosystem services provided by arthropods in apple orchards: pollination and biological control. We used relative decrease in colonies to assess biological control of the major apple aphid pest, and measured pollination through fruit set, number of seeds per apple and pollinator visitation. Additionally, we monitored the organisms responsible for pollination and biological control services and established the impact of pollination on apple quality. Our results show a strong effect of organic management on biological control and on the temporal dynamic of natural enemy–pest interactions. Parameters such as aphid colony suppression, first and repeated occurrence of natural enemies, natural enemy species evenness and natural enemy abundance were significantly higher in organic compared to conventional orchards. Predatory bugs were the natural enemies best‐affected by organic management and played a key role in early predation of aphids preventing colony growth. In this instance, pollination was not influenced by organic management. It is likely due to the temporal scale at which this service is delivered, a scale that differs greatly from biological control, combined with differences in the dispersal capacity of the organisms involved. Fruit weight, calcium, potassium and magnesium content were positively affected by pollination success. Synthesis and applications. We found that organic management in apple orchards preserves the local natural enemy community, and specifically predatory bug populations, essential for early aphid colony suppression. Our results suggest that, in conventional orchards, local management options that decrease or even eliminate pesticide use early in the season would increase the biological control of aphids. This would lead to reduction in apple damage at harvest. Our results on pollination success indicate that the implementation of organic management at orchard scale does not enhance pollination services for apple growers.

“…The role of vegetation in providing shelter has been little studied. Perennial plant communities, such as beetle banks, provide refuges to protect populations of natural enemies against disturbances in the vicinity of cropped habitats (MacLeod et al 2004;Porcel et al 2017). The density and complexity of vegetation architecture and litter are important drivers of microclimate affecting vulnerable stages in the life cycles of arthropods (oviposition, estivation, hivernation, Griffiths et al 2008).…”

Understanding plant–arthropod interactions in multitrophic communities to improve conservation biological control: useful traits and metrics

The role of biodiversity in the delivery of ecosystem services is increasingly being studied by traitbased functional approaches. Here, we review and discuss the contribution of a trait-based approach to understanding plant-arthropod interactions and improving conservation biological control. The stable biological control of multispecies herbivore communities requires functional diversity and a redundancy of natural enemies, including specialists and generalists, with minimal antagonistic interactions. The management of arthropod communities through plant community requires the plant community to perform several functions, including the provision of diversified trophic resources and appropriate physical habitats. Many studies have investigated the ability of plants to provide these functions, but many of the results obtained were limited to single species. The description of communities in terms of traits underlying trophic and non-trophic interactions between plants and animals would make it possible to extrapolate findings to other species. Studies on plant-herbivore and plant-pollinator interactions have identified several traits as important for trophic resource provision, in terms of resource quantity, accessibility, quality and temporal availability. By contrast, traits relating to physical habitat provision and microclimate modification have been little explored. Several metrics describing the functional composition and diversity of communities have been proposed, to extend the trait-based approach to plant community level, but the extent to which multitrophic communities are affected by plant traits remains largely unexplored. The next step will be to identify the combinations of these plant community metrics best explaining their impact on arthropod communities and disentangling the roles of plant functional composition and diversity.

Se aportan nuevos datos sobre las especies del género Chrysopa Leach, 1815 citadas en la Península Ibérica y Baleares. De las especies mencionadas en su fauna sobre las que existían dudas en la veracidad de sus citas o se había cuestionado su validez taxonómica, se ha estudiado y anotado la mayoría del material correspondiente, tanto ibérico como material de comparación de otras zonas, con la intención de dilucidar estas cuestiones. Bien sea para constatar su presencia en su fauna, con la correspondiente confirmación o corrección de ciertas citas, como para verificar la identidad de algunas especies de este género y algunas de sus variedades descritas, con la confirmación o revisión de su identidad taxonómica. Se confirma la validez de Chrysopa nierembergi Navás, 1908 respecto a C. formosa Brauer, 1850 y se designa para ella Lectotipo. También se designa Lectotipo para Chrysopa nierembergi var. andreui Navás, 1910 y para Chrysopa nierembergi var. clara Navás, 1915, ambas son consideradas sinónimas de C. nierembergi. Se dan por válidas solo dos de las citas ibéricas de Chrysopa phyllochroma Wesmael, 1841, y se confirma la presencia de Chrysopa dubitans McLachlan, 1887 en la fauna ibérica. Se eleva a categoría de especie la variedad Chrysopa nierembergi var. nitens Navás,1909, considerándola como especie válida: Chrysopa nitens Navás, 1909 stat. prom., designando para ella Lectotipo. De estas cinco especies se anotan sus caracteres de morfología externa y de genitalia masculina, así como algunos elementos diagnósticos y comparativos entre ellas o con otras especies próximas. Se comentan y se discuten algunos caracteres habitualmente utilizados en la identificación de las especies de Chrysopidae (variabilidad y persistencia de la pigmentación tegumentaria de los ejemplares según poblaciones, tiempo transcurrido desde su recolección y modo de conservación; uñas dilatadas en su base o no). Por último, y hasta que no existan nuevas evidencias, se descarta definitivamente la supuesta presencia de Chrysopa abbreviata Curtis, 1834 y Chrysopa walkeri McLachlan, 1893 en el solar ibérico, ya que está basada en citas antiguas imprecisas o inconsistentes, no corroboradas por nuevo material. El género Chrysopa está representado en la fauna Ibero-Balear por diez especies, de las cuales se anota y recopila la información existente, y se aporta nuevo material, también se actualizan la clave de especies de este género y los mapas de su distribución en la Península Ibérica y Baleares.
