RESUMEN

Para este trabalho, foram considerados os resultados de quatro estudos que amostraram abelhas nas flores nos dois principais biomas do Estado de São Paulo: Mata Atlântica (3 localidades) e cerrado (4 localidades). Foram coletadas 276 espécies de abelhas, pertencentes a 88 gêneros: 207 espécies e 78 gêneros na Mata Atlântica e 105 espécies e 40 gêneros no cerrado. Apidae foi a família mais representada nos dois biomas. Nas áreas amostradas, as abelhas visitaram 433 espécies de plantas: 361 na Mata Atlântica e 75 no cerrado.


For this work, we considered the results of four studies that sampled bees on flowers in the two main biomes of São Paulo State: Atlantic forest (3 locations) and 'cerrado' (4 locations). We found 276 species of bees belonging to 88 genera: 207 species and 78 genera in the Atlantic forest and 105 genera and 40 species in the 'cerrado' biome. Apidae family was the most represented in both biomes. In the sampled areas, bees visited 433 plant species: 361 in the Atlantic forest and 75 in the 'cerrado'.

RESUMEN

We developed a bioassay to measure the flying power of drone, in order to determine which drones could reach a drone congregation area. A wind tunnel was used to test unparasitized drones and drones slightly parasitized by one or two mites during pupal development, and counts were made of the number of spermatozoa that they produced. Drones parasitized with one mite flew as long as control drones ( = 6Æ55ö and 6Æ48ö, respectively, P = 0.512); however, those that had been infested by two mites flew significantly less ( = 2Æ16ö, P<0.001). There was a significant positive correlation (P<0.01) between flight duration and the number of spermatozoa per drone in control group (r = 0.53), and in both the one mite (r = 0.43) and two mite (r = 0.54) groups. Drones infested during development with one or two mites produced 24 and 45% fewer sperm, respectively.
