Plantengallen (Plant Galls)

Language: Dutch
Plantengallen provides information on the history, biology and ecology of plant galls and their host plants. It extensively illustrates over 400 species of galls, caused by nematodes, bacteria, aphids, psyllids, sawflies, chalcid wasps, gall midges, gall wasps, beetles, flies, butterflies, mites, plants, and fungi. Each of these groups is introduced with general information, followed by more detailed information of the all species belonging to these groups.

Photos show characteristic details, but also variations in form, sections, and sometimes the agent causing the gall. The book concludes with an extensive reference list, a glossary, and lists of synonyms, Dutch species names, and host plants with the species found on them.
Plantengallen is a reference work aimed at amongst other entomologists, phytopathologists, horticulturists, and arborists.
The extensive photo collection will likely be of most interest to English language readers.
