In viticulture, insects occur mainly as pests (picture), but there are also so-called beneficial insects that are also deliberately used against other pests. The harmful insects are conventionally controlled with insecticides. In organic viticulture, however, environmentally friendly methods are preferred, such as the confusion method or also protective walls as shown in the picture below. See also various insects under Beetles, Caterpillars and Butterflies and a complete list of all diseases and pests under Vine Enemies.
The wein.plus encyclopaedia is a comprehensive, well-researched reference work. Available anytime and anywhere, it has become an indispensable part of teaching, used by students and myself alike. Highly recommended!Dominik Trick
