| description | The use of agrochemicals is harmful to bees visiting agricultural crops, reducing production gains from pollination, but the effect of fungicides on these bees is not known. The objective of this study was to verify the effect of bee visitation influenced by different fungicides on the tomato crop and on the deposition of pollen grains on the stigma, number of seeds, mass and fruit size. The experiment was conducted with 10 treatments: (T1) control treatment, without application of agrochemicals; (T2 and T3) Bacillus subtilis in different application frequencies; (T4) copper hydroxide; (T5) B. subtilis and copper hydroxide; (T6) acibenzolar-S-methyl; (T7) (trifloxystrobin+tebuconazole) and B. subtilis; (T8) copper hydroxide+Mancozeb; (T9) propineb+(trifloxystrobin+ tebuconazole); (T10) (trifloxystrobin+tebuconazole)+B. subtilis+copper hydroxide. The presence of the pollination mark on the flower, the pollen load of the stigmas, the number of seeds per fruit, and the size and mass of the fruits were determined in each treatment. Subsequently, the mortality rate of Melipona quadrifasciata (Hymenoptera, Apidae) exposed to four fungicides (trifloxystrobin+tebuconazole; manganese and zinc; copper hydroxide; Bacillus subtilis) was estimated. The mortality rate of M. quadrifasciata over 24 h of evaluation was higher in the treatments with copper hydroxide and trifloxystrobin+tebuconazole (75 and 50%, respectively). The mortality rate was lower in the treatments with manganese and zinc and Bacillus subtilis and in the control treatment. The treatments with trifloxystrobin+tebuconazole reduced the presence of bite marks on the flowers and of pollen grains on the flower stigma. The fruits of the control treatments and treatments with B. subtilis and copper hydroxide were larger and had greater mass, as compared to other agrochemicals. Thus, a higher number of pesticide applications on the tomatoes reduced bee visitation rates to the flowers and, consequently, reduced the amount of pollen grains deposited on the stigmas, also reducing the fruit production. |

El uso inapropiado de agroquímicos es perjudicial para las abejas que visitan los cultivos agrícolas, lo que reduce la producción por la afectación de la polinización y son pocos los estudios sobre este tema. El objetivo de este estudio fue verificar la incidencia de diferentes fungicidas sobre la visita de abejas en cultivos de tomate y sus efectos sobre la deposición de granos de polen en el estigma, número de semillas, masa y tamaño del fruto. Los experimentos consistieron en 10 tratamientos que fueron: (T1) tratamiento control sin agroquimicos; (T2 y T3) Bacillus subtilis en diferentes frecuencias de aplicación; (T4) hidróxido de cobre; (T5) B. subtilis e hidróxido de cobre; (T6) acibenzolar- S-metilo; (T7) trifloxistrobina+tebuconazol y B. subtilis; (T8) hidróxido de cobre + Mancozeb; (T9) propineb+(- trifloxistrobina+tebuconazol); (T10) (trifloxistrobina+tebuconazol)+B. subtilis+hidróxido de cobre. Se determinó la presencia de la marca de polinización en la flor, la carga de polen en los estigmas, el número de semillas por fruto, y el tamaño y masa de los frutos en cada tratamiento. Posteriormente, se estimó la tasa de mortalidad de Melipona quadrifasciata expuesta a cuatro fungicidas (trifloxistrobina+tebuconazol, manganeso y zinc, hidróxido de cobre, Bacillus subtilis). La tasa de mortalidad de M. quadrifasciata en 24 horas de evaluación fue mayor en los tratamientos con hidróxido de cobre y trifloxistrobina+tebuconazol (75 y 50%, respectivamente). La tasa de mortalidad fue menor en los tratamientos con manganeso y zinc, Bacillus subtilis y el tratamiento de control. Los tratamientos con trifloxistrobina y tebuconazol redujeron la presencia de marcas de mordida y granos de polen en el estigma de las flores. Los frutos de los tratamientos control y con B. subtilis e hidróxido de cobre fueron más grandes y tuvieron mayor masa. Por lo tanto, un mayor número de aplicaciones de pesticidas en las plantas de tomate reducen las tasas de visitas de abejas en las flores y en consecuencia, la cantidad de granos de polen depositados en los estigmas afectando también la producción de los frutos.
