Forscher haben das erste, vollständig aus Plastik gebaute Bienennest gefunden. Es ist nur ein kleines und der Bau noch nicht abgeschlossen, das Nest besteht interessanterweise ausschließlich aus weißen „Bauteilen“. Die Wissenschaftler spekulieren darüber, ob das Plastik einen Vorteil für die Insekten darstellt, oder das Plastik aus Mangel an natürlichem Material benutzt wurde. So oder so: Anthropozän is here.
Agricultural plastic waste can alter wildlife diversity and behavior. Species survival will depend on their ability to adapt to new environmental conditions. In a seed-producing farm, a Megachile sp. nest made fully with plastic was found in a trap nest. This record represents the first one worldwide on revealing the use of plastic in the total construction of a bee nest.
Aus dem Paper:
The plastic nest found was formed by three cells of 1.27 ± 0.12 cm (Figure 1c). The cells were composed by circular and oblong plastic pieces (9.76 ± 1.81 × 6.57 ± 0.96 mm, n = 54) arranged in an imbricated manner (Figure 1d). The first two cells were only formed by light blue plastic of shopping bag consistency. The third cell was made entirely of white plastic, thicker than the previous one. Among the three cells, one contained a dead larva; from the other, the adult seemed to have emerged from the nest; and the third cell was not finished. For this reason, we do not know the identity of the species that built the nest. However, it could be Megachile rotundata (Fabricius), an exotic species caught in flowers of our study site, and for which there is a record of plastic use as brood cell material (MacIvor and Moore 2013).

The use of plastic as a resource for nest construction suggests that certain species of bees would have adaptive flexibility in the face of changes in environmental conditions. The replacement of natural materials by plastic could appear in response to a limitation in the availability of vegetation in the fields, which could be directly linked to the use of herbicides (Nicholls and Altieri 2013). On the other hand, the use of plastic as the only resource for the construction of the nest could be associated with the preference of this material over natural ones. Some evidence shows that the use of synthetic materials in nesting could bring adaptive advantages (Suárez-Rodríguez et al. 2012)
