Objetivo: Evaluar la presencia de la entomofauna floral asociada al girasol (Helianthus annuus L.) cultivado en el municipio de Cuautitlán Izcalli, Estado de México.Diseño/metodología/aproximación: Se realizó un monitoreo diurno y registro de los insectos que visitaron al cultivo, y en las fases fenológicas en las que se presentaron.Resultados: En total se identificaron 18 especies asociadas al cultivo; éstas fueron clasificadas en polinizadores, depredadores, defoliadores y chupadores. La entomofauna en el girasol básicamente se compone de insectos polinizadores y algunos insectos plaga como la mosca de la fruta (Neotephritis finalis).Limitaciones del estudio/implicaciones: Es un trabajo exploratorio que debe complementarse con más observaciones de campo en el cultivo de girasol.Hallazgos/conclusiones: Se determinó la actividad de Chauliognathus hastatus como un polinizador en este cultivo y no solo Apis mellifera L. como la literatura lo cita.

AbstractBee species provide essential ecosystem services and maintain floral biodiversity. However, there is an ongoing decline of wild and domesticated bee species. Since agricultural pesticide use is a key driver of this process, there is a need for a protective risk assessment. To achieve a more protective registration process, two wild bee species, Osmia bicornis and Bombus terrestris, were proposed by the European Food Safety Authority as additional test surrogates. We investigated the acute toxicity (median lethal dose, LD50) of multiple commercial insecticide formulations towards the red mason bee (O. bicornis) and compared these values to honey bee (Apis mellifera) regulatory endpoints. In two thirds of all cases O. bicornis was less sensitive than the honey bee. By applying an assessment factor of 10 on the honey bee endpoint a protective level was achieved for 87% (13 out 15) of all evaluated products. Our results show that O. bicornis as a non-sensitive species is rarely an adequate additional surrogate species for lower tier risk assessment. Given the currently limited database, the honey bee seems sufficiently protective in acute scenarios as long as a reasonable assessment factor is applied. However, additional surrogate species such as O. bicornis and B. terrestris are still relevant for ecologically meaningful higher tier studies.

O girassol (Helianthus annuus L.) é uma espécie de polinização cruzada, cujos principais polinizadores são as abelhas. Este trabalho teve por objetivo obter informações sobre a diversidade de abelhas visitantes nos capítulos de girassol, fornecendo subsídios para identificar os possíveis polinizadores efetivos na região do Recôncavo Baiano. As coletas das abelhas foram realizadas no período de setembro-outubro de 2004, janeiro-fevereiro e maio-junho de 2005 sobre os híbridos de girassol, "AG 920" e "AG 930", cultivados na área experimental de Entomologia do Centro de Ciências Agrárias e Ambientais da Universidade Federal da Bahia, em Cruz das Almas-BA. Um total de 26 espécies de abelhas foram identificadas, sendo que Apis mellifera foi a mais abundante (58,32%), seguida de Nannotrigona testaceicornis (18,53%) e Trigona spinipes (11,37%). As demais espécies apresentaram uma freqüência relativa inferior a 5%.
