Spiders are exceptionally diverse and abundant organisms in terrestrial ecosystems and their evolutionary success is certainly related to their capacity to produce different types of silks during their life cycle, making a specialized use on each of them. Presenting particularly tandemly arranged amino acid repeats, silk proteins (spidroins) have mechanical properties superior to most synthetic or natural high-performance fibers, which makes them very promising for biotechnology industry, with putative applications in the production of new biomaterials. During the evolution of spider species, complex behaviors of web production and usage have been coupled with anatomical specialization of spinning glands. Spiders retaining ancestral characters, such as the ones belonging to the Mygalomorph group, present simpler sorts of webs used mainly to build burrows and egg sacs, and their silks are produced by globular undifferentiated spinning glands. In contrast, Araneomorphae spiders have a complex spinning apparatus, presenting up to seven morphologically distinct glands, capable to of rigidness and elasticity associated with distinct behaviors. Aiming to provide a discussion involving a number of spider silks? biological aspects, in this review we present descriptions of members from each family of spidroin identified from five spider species of the Brazilian biodiversity, and an evolutionary study of them in correlation with the anatomical specialization of glands and spider?s spinning behaviors. Due to the biotechnological importance of spider silks for the production of new biomaterials, we also discuss about the new possible technical and biomedical applications of spider silks and the current status of it.

Spathodea campanulata is an African plant of African origin introduced in South America and other tropical and subtropical areas for ornamental purposes. This plant is related to insect mortality, bees included. However, its effects on the Neotropical Melipona are yet unknown. Thus, this study aimed to evaluate the effect of S. campanulata nectar and pollen on the survival of Melipona fasciculata and M. seminigra workers. A total of 120 newly emerged workers of each species were confined in boxes, without the presence of the queen, and divided in groups of 10 individuals. They were submitted to the following diets: S. campanulata nectar or 11% sucrose solution (nectar control); 11% sucrose solution and S. campanulata pollen or 11% sucrose solution and the species? original pollen (pollen control). The higher mortality of workers was detected on the experimental groups, with toxics nectar and pollen (M. fasciculata, p<0.01; M. seminigra, p<0.01) than on the respective controls. Our results point that nectar and pollen affected the survival of M. fasciculata and M. seminigra worker bees. Thus, S. campanulata is not a recommended plant to provide food resources for stingless bees. |
