The sugar industry, political authorities, and scientific institutions in the regulation of saccharin: Valencia (1888-1939)

In the late-nineteenth century food production and trade were greatly transformed. Changes in the food chain gave rise to new problems connected with food safety and food quality, which caused new controls to be introduced throughout Europe. In this paper I will contribute to ongoing debates by focusing on the regulation of saccharin in an agrarian city in the south of Europe, Valencia. The laboratory-made sweetener was introduced into the food market at the turn of the century, becoming highly controversial shortly afterwards. Several local groups of players got involved in this dispute. The sugar industry was not only an important stakeholder in the passing of some specific laws that were to constrain the use of saccharin, but also the main driver of regulation, primarily in periods when saccharin could become a serious competitor and reduce the sector's profit. Furthermore, the combined work of the sugar industry and the municipal laboratories was essential for the implementation of regulations. It was in such municipal laboratories that scientists played a main role in regulation. My paper will address the commercial disputes linked to the use of saccharin and the limited role of science and scientists in its control.     

New information about the third stage larva and larval habitat of Microdon (Chymophila) bruchi Shannon, 1927 (Diptera,Syrphidae) from Argentina

ABSTRACT

In this paper, we provide new biological information about Microdon(Chymophila) bruchi Shannon, 1927. We present new records of M. bruchi in nests of Camponotus mus Roger, 1863 built inside Vitis vinifera L. plants from Argentina (Mendoza Province) and records of this species for Catamarca and Entre Ríos, Argentina. DNA barcodes and data on morphology and locomotion for third-stage larvae are provided. An identification key is also given to distinguish M. bruchi from other Neotropical species of Chymophila. We designate a lectotype for Microdon bruchi Shannon, 1927, and we consider Microdon argentinae Hull, 1937 a junior synonym of M. bruchi.
