Obscure mealybug
effect is a 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 [...] 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 [...] reduced level of photosynthesis in the leaves also reduces flower and fruit production. In ornamental crops, the mere presence of mealybugs is sufficient
