Life

After finishing school in Nuremberg , Friedrich Ludwig Stellwaag studied natural sciences in Munich , Würzburg and Erlangen , especially zoology. He received his doctorate in 1909 with a zoological topic (construction and mechanics of the bee's flying apparatus ). He then went on study trips to numerous countries (Italy, Switzerland, France, America and Africa). His work as an assistant at the Zoological Institute of the University of Erlangen led to his habilitation in 1913. In the years 1917–1934 Stellwaag was head of the zoological station of the state teaching and research institute in Neustadt an der Weinstrasse . In 1935 he switched to the state teaching and research institute for viticulture, fruit growing and horticulture in Geisenheim . There he was in charge of the Institute for Plant Diseases until his retirement in 1954.

Scientific work

Phytomyza chaerophylli ( Agromyzidae ) on chervil ( Chaerophyllum sp. (Umbelliferae))

Stellwaag's main area of ​​work was the control of vine, fruit and garden pests . He was a pioneer of organic viticulture and as early as 1924 he wanted a holistic view of viticulture. His most important work appeared in 1928: The viticulture insects of the cultivated countries. Instructional and manual . Also to be emphasized is the 1936 pest control in viticulture. Basics and advances in horticulture and viticulture . As secretary of the German Society for Applied Entomology and as co-editor and author of the Scoreboard for Pest Science (together with Karl Escherich ), he documented his main field of work in many articles: pest control and the use / mode of action of insecticides . Numerous pamphlets and leaflets testify to his tireless work as a scientist and consultant. His work includes a leaf mine collection owned by the Wiesbaden Museum (MWNH). Stellwaag published a compilation of the relevant finds in the series of publications of the Nassau Association for Natural History , of which he was a member from 1936 to 1973. This collection was checked by Erich Martin Hering during Stellwaag's lifetime. Furthermore, until 2009, the Phytopathological Institute in Geisenheim housed his extensive insect collection. About 130 insect boxes then passed into the possession of the State Museum Wiesbaden. The collection mainly covers the region of Franconia and southern Palatinate. The voices are a special focus . A faunistic evaluation takes place in the Museum Wiesbaden.
