The differentiation of workers into morphological castes represents an important evolutionary innovation that is thought to improve division of labor in insect societies. Given the potential benefits of task-related worker differentiation, it is puzzling that physical worker castes, such as soldiers, are extremely rare in social bees and absent in wasps. Following the recent discovery of soldiers in a stingless bee, we studied the occurrence of worker differentiation in 28 stingless bee species from Brazil and found that several species have specialized soldiers for colony defence. Our results reveal that worker differentiation evolved repeatedly during the last ~ 25 million years and coincided with the emergence of parasitic robber bees, a major threat to many stingless bee species. Furthermore, our data suggest that these robbers are a driving force behind the evolution of worker differentiation as targets of robber bees are four times more likely to have nest guards of increased size than non-targets. These findings reveal unexpected diversity in the social organization of stingless bees. |

The aimed to evaluate the effect of packages and different environment conditions in the maintenance of physiologic quality of Amaranthus cruentus seeds in the period of 300 days. The seeds used were from the cultivar BRS Alegria indicated for use in Brazilian winter. The experimental design completely randomized in factorial scheme (storage environment × package type × storage period) with four replicates. The amaranth seeds storage in plastic packages, in refrigerator and cold chamber, resulted in better germination maintenance ability. The conditioning in PET package, in natural and cold chamber environments promoted better results in relation to germination. The storage period did not present significant effect for the seeds stored in refrigerator and PET, although, for paper package there was reduction. The amaranth seeds, cv. BRS Alegria, can be stored in cold chamber for until 300 days, conditioned in PET, without reduction of its physiologic potential. |
