Marga Roden

The with the scale insects related plant pests occur worldwide. There are around 70 species with host plants that vary in size (from 2 to 8 mm in length), shape (round or oval) and color (eg yellow, bronze, red or light brown). There are several on vines specialized species that occur mainly in North and South America and South Africa. The most common species is called Margarodes prieskaensis, others are margarodes capensis, margarodes greeni, margarodes trimeni, margarodes vitis and margarodes vredendalensis. The mating by winged male and female insects occurs above ground. The female can produce more than 1,000 eggs in several ovipositions, which are deposited underground. The resulting wart-like nymphs in the form of a cyst (pictured left) feed similarly to the phylloxera of plant roots and can be one Rebstock destroy within a few years. After pupation, this results in the winged sexual animals (picture on the right). A finishing is not effective because no resistant vine species are known.
