The beetle it's a insect beetle particularly widespread in northern Italy. Its scientific name is Melolontha melolontha. The peak of its diffusion is reached in the spring months of April and May, hence the name that derives from it.
Recognizing the beetle is not particularly complicated: with a length of about 30 mm, the insect beetle has an elongated shape of dark brown color that is decidedly less pleasant than the red ladybug with black spots.
The beetle larvae are about 40 mm long, white in color.
But let's see immediately why the beetle is a dangerous insect for crops. The reason is simple and twofold: the adult beetle feeds on leaves and is harmful to your plants, while its larvae feed on the roots, blocking the growth of your plants.
The larval period of the beetle can last about 1 year from the moment it takes place 30 cm underground. The life cycle of the beetle is 2/3 years.
Beetle, an insect capable of causing serious damage to plants
The beetle bug can be a very harmful species for your plants, among its favorite victims we find the leaves of fruit trees.
A massive attack by the insect beetle causes total defoliation of the plant.
The attack of the larvae is even more dangerous because, as written above, they feed on the roots of your plants, causing them to collapse within 24 hours.
Prevention is certainly better than cure! Especially if you find yourself having to use chemicals.
How is it possible to carry out an accurate prevention of your plants against this deadly parasite?
The best way to prevent insect beetle larvae is to constantly loosen the soil.
Compact soil is the natural habitat of the insect beetle larva, moving it will make it very difficult for this parasite to settle.
Another strategy to combat the beetle is to install a bat house on the trunks of your plants, the so-called "bat box".
The bat is in fact one of the main predators of insects and beetles and also constitutes a totally natural remedy that therefore allows you not to use chemical insecticides.
If you want to try to fight the beetles by using bats, you can try to buy the house directly on Amazon by following this link.
Another effective method against the beetle is the use of very mature organic fertilizers that will make the soil unpleasant for this parasite.
Lately they are also using crows and above all diptera that feed on the larvae of the beetle.
Insect beetle: how to fight it
Unfortunately for your plants, if a beetle attack is already underway, the only possible solution is to fight it through several joint interventions.
As previously mentioned, if you notice the larvae (especially in winter), move the soil, in doing so the larvae will die of cold within a few days.
In the event of an infestation, you will have to use special pesticides for beetles, using the foresight to apply them early in the morning when the weather is still humid, so as to increase their effectiveness.
Are the beetle and the ladybug the same insect?
Many people are convinced that the beetle and the ladybug are the same insect while in reality they are two totally different species.
Unlike the beetle, the ladybug is up to 10 mm long and is characterized by a round shape with contrasting colors and a very showy, red speck with black dots.
The ladybug unlike the beetle does not create problems for crops and on the contrary it can be useful as it feeds on mites.
