All the usual wine varieties are made from (different) types of Vitis vinifera [...] and 10,000 varieties of Vitis vinifera grapes, but only a few play an important commercial role when it comes to the production of wine, but also table [...] species of Vitis . The plant comes originally from the Mediterranean region, central Europe and southwestern Asia and thus has been cultivated in Morocco

Long-tailed mealybug

an adequate intake of protein, mealybugs must therefore ingest large quantities of sap, getting rid of the excess sugars in the form of honeydew. Charac [...] the reduced level of photosynthesis in the leaves also reduces flower and fruit production. In ornamental crops, the mere presence of mealybugs is sufficient [...] reduction of photosynthesis and therefore the yield. Flowers and fruit often drop off. Plant sap is rich in sugars, but low in proteins. In order to gain

This uniform distribution results in effective biological pest [...] distribution in high-tech cultivations. The Airobug special fan, in combination with the revolving dosage pot, ensures a uniform release of carrier material
