The Bacterial and Fungal Gut Microbiota of the Greater Wax Moth, L. Consuming Polyethylene and Polystyrene.

Plastic production has been increasing exponentially in the last 60 years, but plastic disposal is out of control, resulting in the pollution of all ecosystems on Earth. Finding alternative environmentally sustainable choices, such as biodegradation by insects and their associated gut microbiota, is crucial, however we have only begun to characterize these ecosystems. Some bacteria and one fungus have been previously identified in the gut of Greater Wax Moth larvae ( L.

Consumption of low-density polyethylene, polypropylene, and polystyrene materials by larvae of the greater wax moth, Galleria mellonella L. (Lepidoptera, Pyralidae), impacts on their ontogeny.

Low-density polyethylene (LDPE), biaxially oriented polypropylene (BOPP), and expanded polystyrene (EXPS) are the most common plastics found in every home of the world, but only ~ 10% enter the recycling chains. Consequently, the study of plastic biodegradation by microorganisms and insects, such as the wax moths, has gained special interest. Galleria mellonella (L.

Revision of "Aemilia" pagana Species-Group (Lepidoptera: Erebidae: Arctiinae), with a Description of a New Endemic Species and Comments on the Conservation Status.

A taxonomical rearrangement of "Aemilia" pagana species-group is proposed: Leucanopsis pagana (Schaus in Proc Zool Soc London 1894:225-243, 1894) comb. nov. and L.

An optimality criterion to determine areas of endemism.

A formal method was developed to determine areas of endemism. The study region is divided into cells, and the number of species that can be considered as endemic is counted for a given set of cells (= area). Thus, the areas with the maximum number of species considered endemic are preferred.
