Oziorrinco, a very annoying insect both from an aesthetic and a substantial point of view, which attacks ornamental and fruit plants without being picky. In Italy it is present, in the center and south above all, and starts doing damage in May, continues in June, takes holidays in July and August but then, after the summer heat, it resumes its activity until the cold arrives. Let's see how to fight it, with effective methods: natural ones.

Oziorrinco: what it is

It is an insect from the family of Curculionid beetles, shows up after dusk, before he rests in the underground tunnels where he gladly takes refuge. It comes out at the foot of the plants that it will disturb and inexorably begins to climb up the trunk.

It passes from branch to branch, leans on any "crutches" and supports and does everything to reach as many leaves as possible. The goal is to find the youngest ones and keep eating them until morning. At sunrise, theOziorrinco he goes home, full and satisfied, leaving behind a disaster.

Oziorrinco: larvae

Even the larvae of this insect manage to be harmful: it is a born enemy. They look rather gross, they are white, fleshy, with "The head" yellow but tending to reddish. They are about the size of about 1 cm, can be seen with the naked eye quietly but above all they can be recognized at a glance for their typical C-shaped body shape. Oziorrinco adults, even the larvae live underground, hidden, but they prefer to attack the plants at the roots, whether they are horticultural species, whether they are fruit or ornamental.

Oziorrinco: danger for the olive tree

L'Oziorrinco constitutes a great danger for this plant so widespread precisely where this insect is widespread. As soon as it can, it launches itself at the attack of the youngest and most defenseless leaves of the olive tree as well as other fruit and ornamental plants, and eats them.

It causes numerous crescent erosions in one night: it is not only an aesthetic damage, on the contrary, the real problem is that by gnawing they hinder the photosynthesis capacity of the victim plants, compromising the formation of the crown. This means that the olive tree, like other spouse plants, undergo a strong and unwelcome slowdown in growth.

Oziorrinco: how to fight it

It is challenging but not impossible to fight there'Oziorrinco. I suggest two products that are readily available in stores in gardening or plant accessories, as well as online. We can use a fast-acting insecticide that kills the annoying insect. With 22 euros we get a bottle of 100 ml and instructions for using it to the fullest

An alternative to 9 euros are baits with insecticide, to hunt soil insects, to be applied before or during transplanting or sowing. They burrow along the line or in the vicinity of the plants and, thanks to the food substances they contain, they are capable of attracting our enemies, mortally.

To better plan the use of these anti weapons Oziorrinco it is good to know that their activity lasts a long time, at least 4 months, in two phases: May-June and September-October. The problem is that often, in addition to the exhausting duration, we find ourselves having to look after several species that occur simultaneously. A chemical product it should be applied repeatedly and for a long time, this is not the best, especially for fruit plants. Better the fight biology, implemented for a long time and with considerable success.

Oziorrinco: biological struggle

One of the natural, non-chemical methods consists of the "classic" manual collection of adult Oziorrinco specimens. It should be done at night: the branches are shaken making them fall to the ground after having spread some tarps under the plants. Fallen bodies must be burned.

Another perfect idea for "do it yourself" is the application of cardboard strips to be fixed at 30-40 cm from the ground, on the trunk, covered with sticky but natural material that blocks insects that will remain helpless waiting for death. .
