Urban buzz: role of wild pollinators in pollen load on 'Solanum lycopersicum' in Rosario

The wild pollinator fauna in peri-urban vegetable gardens of Rosario (Santa Fe, Argentina) remains largely unknown, despite the fact that numerous crops, such as Solanum lycopersicum var. platense (tomato), benefit from the activity of these insects. Although tomatoes can produce fruits through self...

description The wild pollinator fauna in peri-urban vegetable gardens of Rosario (Santa Fe, Argentina) remains largely unknown, despite the fact that numerous crops, such as Solanum lycopersicum var. platense (tomato), benefit from the activity of these insects. Although tomatoes can produce fruits through self-pollination, insect-mediated pollination significantly enhances fruit production. This study had two main objectives: (i) to compile an inventory of wild pollinators in peri-urban tomato gardens, and (ii) to quantify pollen deposition on stigmas caused by insect visits. Observations were conducted on 600 tomato inflorescences in four gardens, recording the abundance, frequency, and behavior of floral visitors. The amount of pollen deposition on stigmas of flowers exposed to visitors was compared with that on stigmas of flowers excluded from visitors (n = 96). Nine morphospecies were identified, five of which corresponded to bees capable of performing buzz pollination, with the family Halictidae standing out for its abundance (107 visits). Bees that collect pollen through buzzing accounted for the majority of visits. The exposed stigmas showed more than twice as many pollen grains as the stigmas of excluded flowers. Peri-urban gardens may function as foraging sites for native pollinators, contributing to an increase in pollination.

La fauna de polinizadores silvestres en huertas periurbanas de Rosario (Santa Fe, Argentina) permanece prácticamente desconocida, a pesar de que numerosos cultivos, como Solanum lycopersicum var. platense (tomate), mejoran su producción con estos insectos. Aunque el tomate produce frutos por autopolinización, la polinización mediada por insectos mejora notablemente la producción de frutos. Este estudio tuvo dos objetivos principales: i) elaborar un inventario de polinizadores silvestres en huertas periurbanas de tomate, y ii) cuantificar el depósito de polen en los estigmas provocado por la visita de insectos. Se realizaron observaciones en 60 inflorescencias de tomate en 4 huertas, registrando la abundancia, frecuencia y comportamiento de los visitantes florales. Se comparó la cantidad de polen depositado sobre estigmas de flores expuestas a los visitantes con la cantidad de polen depositado sobre estigmas de flores excluidas de visitantes (n=96). Se identificaron nueve morfoespecies de las cuales cinco correspondieron a abejas capaces de realizar polinización por zumbido (buzz‑pollination), destacándose la familia Halictidae con una abundancia de 107 visitas. Las abejas que recolectan polen por zumbido representaron la mayoría de las visitas. Los estigmas expuestos mostraron más del doble de granos de polen que los estigmas de flores excluidas. Las huertas periurbanas pueden estar actuando como sitios de alimentación para polinizadores nativos, lo cual trae aparejado aumentos en el proceso de polinización. A fauna de polinizadores silvestres em hortas periurbanas de Rosario (Santa Fe, Argentina) permanece praticamente desconhecida, apesar de diversas culturas, como Solanum lycopersicum var. platense (tomate), melhorarem sua produção com esses insetos. Embora o tomate possa produzir frutos por autopolinização, a polinização mediada por insetos aumenta significativamente a produção de frutos. Este estudo teve dois objetivos principais: (i) elaborar um inventário de polinizadores silvestres em hortas periurbanas de tomate e (ii) quantificar o depósito de pólen nos estigmas causada pelas visitas de insetos. Foram realizadas observações em 60 inflorescências de tomate em quatro hortas, registrando a abundância, frequência e comportamento dos visitantes florais. Foi comparada a quantidade de pólen depositado nos estigmas das flores expostas aos visitantes com a quantidade de pólen depositado nos estigmas das flores excluídas dos visitantes (n=96). Nove morfoespécies foram identificadas, cinco das quais corresponderam a abelhas capazes de realizar polinização por zumbido (buzz‑pollination), destacando-se a família Halictidae pela sua abundância (107 visitas). As abelhas que coletam pólen por zumbido representaram a maioria das visitas. Os estigmas expostos apresentaram mais do que o dobro de grãos de pólen em comparação com os estigmas das flores excluídas. As hortas periurbanas podem funcionar como locais de alimentação para polinizadores nativos, contribuindo para o aumento do processo de polinização.
