Gall midges

These insects (Cecidomyiidae) are widespread worldwide with about 6,000 species. The body length is 0.5 to 4 millimetres, in a few up to 8 millimetres. The body is usually yellow-orange, ochre, light or dark red to almost black. They spend almost their whole life in the larval stage. The larvae of almost all species live monophagous (narrow food spectrum) on only one plant species. The fully developed mosquitoes only live for a short time and hardly take up any food. In Europe, the species leaf gall midge (Cecidomyia oenophila) and the vine flower gall midge (Contarinia viticola) are among the vine pests. The females bore the underside of the leaves and the flower stems and lay their eggs. The hatched two millimetre larvae live in the formed eponymous gall. The vine blossom gall midge lays its eggs in the still closed blossom systems. They do not normally need to be fought, as they are infested by parasites (e.g. chalcid wasps).

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
