“…(Macfarlane & Ferguson 1983;Miñarro & Twizell 2015), there may be potential for different pollinating species to provide complementary roles. This result supports the findings of Rader et al (2013), who found that different pollinating species were likely to provide complementary pollination in Brassica rapa because of variation in their diurnal activity patterns. The dominance of honey bees within the surveyed kiwifruit orchards suggests, however, that wild pollinators are currently contributing minor pollination services, at least during our survey period (10:00 to 15:00 hr).…”

“…Moreover, in New Zealand, there appears to be inconsistency in the diurnal activity of honey bees among crops. For example, in brassica fields, honey bee activity was observed to peak around midday (Rader et al 2013), while in flowering carrot (Daucus carota) fields, peak activity was observed in the afternoon (Howlett et al 2015). These variations in pollinator diurnal activity among crops demonstrate an inability to attribute any of our measured variables as overarching factors that can be used to predict pollinator diurnal activity patterns across crops.…”

“…For vegetable seed crops grown in New Zealand, honey bees, other bees and non-bee pollinators can vary in their flower visitation times (Howlett et al 2013a;Rader et al 2013). Some of this fluctuation may be because of differences in weather variables such as temperature and light intensity (Howlett 2012;Howlett et al 2013a) but peak activity within species may also vary depending on crop species.…”

Different pollinators may vary in their temporal flower-visitation patterns within crops, potentially extending the period pollination may occur. To assess whether this could be the case in kiwifruit, we conducted standardised observational surveys of insects visiting kiwifruit flowers within 31 orchards at three times: 10:00-11:00, 12:00-13:00 and 14:00-15:00 hr. Honey bees (Apis mellifera) represented 92% of visitations (n=5474), but temporal abundances were uneven (predicted abundances were lower at 14:00-15:00 hr). Predatory hover flies (Melangyna, Melonostoma, Allograpta spp.) also showed an uneven temporal pattern. There were no significant differences in the temporal abundances for buff-tailed bumble bees (Bombus terrestris), rattailed hover flies (Eristalis, Helophilus spp.), March flies (Dilophis nigrostigma), flower longhorn beetles (Zorion guttigerum) or the native bees (Leioproctus and Lasioglossum spp.) although, in some cases, low numbers may have masked potential unevenness trends. Variation in diurnal flower-visitation patterns among insects suggests the potential for complementarity between different pollinators.

“…El papel de los insectos polinizadores, y fundamentalmente el de las abejas, ha sido ampliamente demostrado para todo tipo cultivos (Rader et al, 2013), siendo cada vez mayor el número de investigaciones que se preocupan por la pérdida de estos organismos y de los servicios que proveen, mientras que son pocos los estudios que tratan de evaluar o explicar el porqué de su importancia y la necesidad de conservar el servicio de la polinización . Existen algunos trabajos que van desde valoraciones de la riqueza de géneros o especies de polinizadores en una zona (Colteaux et al, 2013;Russo et al, 2015;Wojcik et al, 2008), las relaciones que se establecen entre especies de polinizadores (Badano y Vergara, 2011) o entre polinizadores y plantas (Vilhena et al, 2012), hasta estimaciones acerca la influencia de la polinización sobre la calidad del polen y del néctar (Mensah y Kudom, 2011;Pérez-Balam et al, 2012), la diversidad floral (Ricou et al, 2014) o la actividad de los polinizadores (Rader et al, 2013), pasando por la evaluación final de la producción de semillas y frutos en presencia de estos organismos (Bos et al, 2007;Chautá-Mellizo et al, 2012;Greenleaf y Kremen, 2006;Hoehn et al, 2008;Mallinger y Gratton, 2015;Rogers et al, 2013;Vergara y Badano, 2009).

RESUMENLa polinización es un proceso esencial para el correcto funcionamiento de los ecosistemas y la producción de alimentos, que se ha visto enormemente afectado por diversas actividades antrópicas, siendo cada vez mayor el número de investigaciones encaminadas a entender cómo funciona este proceso. El objetivo de este trabajo es describir las funciones clave que realizan los polinizadores y sus efectos, a través de una revisión sistemática de la literatura científica publicada a lo largo de los últimos diez años. La metodología utilizada consistió en la búsqueda de publicaciones originales en cinco bases de datos, su filtrado por criterios de inclusión y exclusión, y la posterior añadidura de literatura gris. Los resultados muestran una tendencia al establecimiento de objetivos, metodologías de investigación y zonas de estudios similares, así como al estudio predominante de grupos de polinizadores de tipo abejas y abejorros, y al análisis de la polinización desde el punto de vista de la complementariedad de nicho, los patrones de actividad diaria y las asociaciones polinizador-planta, usando medidas como la abundancia de forrajeo, la influencia interespecífica, la deposición de polen o la producción final de frutos y semillas. También se observa una preocupación cada vez mayor por los efectos de las distintas técnicas de manejo agrícola sobre el proceso polinizador y por la necesidad de implementar medidas de conservación adecuadas, concluyéndose que, a pesar de todo ello, sigue siendo necesario continuar avanzando en la investigación dentro de este campo para lograr alcanzar un entendimiento más profundo de la situación.Palabras clave: polinizadores, efecto, función, ecosistemas agrícolas. ABSTRACT Pollination is an essential process for the correct performance of ecosystems and food production, and has been extremely affected by human activities; understanding this process has been the subject of an increasing number of studies.

Variation in size may influence the abundance of visitors and reproductive allocation for cushion plants in the extreme alpine environments. To assess effects of plant size on the abundance of main visitors and reproductive allocation in Thylacospermum caespitosum populations at two altitudes, the abundance of the visitors, visiting frequency, total number of flowers, number of fruits, number of unseeded flowers, and reproductive allocation were investigated during the period of reproductive growth. Concurrently, the effects of plant size on the visitors' contributions to fruit setting rate were assessed by a bagging experiment. Our results showed that flies ( Musca domestica and Dasyphora asiatica ) were the main pollinating insects of T. caespitosum , and they could obvious facilitate ( p < 0.05) the fruit setting rate of this cushion plant. Seed set and floral visitation were significantly influenced ( p < 0.001) by plant size. Moreover, the reproductive allocation and fruit setting rate of T. caespitosum was influenced ( p < 0.001) by plant size. More biomass was allocated to reproduction in plants of greater diameter. There is an increase in reproductive success (increases of fruit number with increase in plant size) in relation to plant size. In conclusion, the extent of M. domestica and D. asiatica to facilitate the fruit setting rate mainly depended on the size of T. caespitosum . Size‐dependent reproductive allocation occurred in T. caespitosum and was the chief factor affecting the contribution of flies to fruit setting rate. These traits reflect reproductive fitness of T. caespitosum related to plant size in extreme alpine environments.
