The mealybug is a parasite particularly widespread in greenhouses, in gardens, in apartments, it attacks in particular some species of ornamental plants, among which we remember the succulents in general, the olive tree, the laurel, the conifers and most of the houseplants . The development of the cochineal in the apartment and in the greenhouse is particularly favored by a dry and poorly ventilated environment. Unfortunately, this parasite resists even the very harsh temperatures present in the garden during the winter, so it is often very difficult to eradicate, as generations increase year by year.
The term cochineal actually refers to some similarly shaped parasites, which cause similar damage; these are generally small-sized parasites, which attack the stems or the leaf blade, from which they suck the sap, causing wounds through which bacteria can penetrate, and which sometimes leave perennial scars even when the parasite is eradicated. The cochineals produce small bags of eggs, typically covered by a waxy or rigid consistency shield, which protects them until hatching; the main problems regarding the fight against these insects often derive from these badges, which repair the eggs from the most common insecticide products.
Among the most common mealybugs we remember Iceria, Saissetia (with rigid external shield, often dark in color), Ceroplastes (with adult forms covered by a waxy shield), Chloropulvinaria (or floccent mealybug), Pseudococcus and planococcus (floury mealybug).
