Popillia Japonica – come sconfiggerla preservando l’ambiente in modo Biologico!

Negli ultimi anni si è assistito ad un aumento considerevole di esemplari di Coleottero Giapponese, o Popillia Japonica, nell’area Nord Ovest del nostro Paese.

This insect, coming from Japan, has been included in the list of most dangerous species..

primi avvistamenti di Popillia Japonica in Italia risalgono al 2014, in prossimità delle sponde Piemontesi e Lombarde del fiume Ticino. L’importazione dell’insetto alieno è probabilmente riconducibile al traffico aereo proveniente dalla suddetta zona, con il primo focolaio individuato nei pressi del Comune di Cameri.


The life cycle of Popillia Japonica in Italy lasts about a calendar year and is divided into two main phases:

  • Larval state, from September to May;
  • Adult form, which mainly occupies the months of June, July and August

The main damage to the environment are:

  • Yellowing and desiccation of turf and roots of young plants, which the larvae feed on;
  • Herodiment and destruction of leaves, flowers and fruits, which mainly eat the adult specimens.

The most affected plant species are:

  • Wild: nettle, bramble, hops, Canadian vine, hawthorn;
  • Fruits: cherry, apricot, plum, apple, khaki, stone, vine;
  • Field: soy and corn;
  • Vegetable garden: tomato, eggplant and basil;
  • Ornamental: rose, hibiscus, wisteria, linden, birch

Chemical treatments

The use of chemical solutions, such as larvicides and insecticides, to be applied to the turf or fruit plants, causes serious damage to the surrounding environment and great risks to human health.

The use of pesticides continues to increase, causing pollution beyond the limits of the aquifer.

Consequently, a strong risk to environmental and human health.

A study on the state of water highlights a massive presence of highly dangerous herbicides and metabolites (degradation products):

Atrazine, simazine, deethylatrazine and desethyl-desisopropyl-atrazine.

The eco-biological solution for the fight against Japanese Beetle

The solution to protect the environment, which does not compromise human health and protects greenery, is guaranteed by the use of pheromone traps.

This remedy, in addition to being very effective, is definitely sustainable, since it does not affect flowers or fruits and is not absorbed by the soil, but consists in inserting a small package, containing two specific essences, inside the trap.

In a completely natural way, male and female specimens of Japanese Beetle are attracted to the pheromone, favoring aggregation and allowing the mass capture of these insects.

Biologic Trap has studied in detail the behavior of the adults of Japanese Beetle, creating a trap that responds in an optimal way to the capture needs of the beetle, favoring its drastic reduction.

Remember that the trap must be positioned away from fruit trees, well away from the area to be protected. In this way the insects will be attracted to the trap, favoring the protection of the green.

The results of the trap will be visible from the first day of application.

Choose sustainable solutions and protect your garden in a natural and organic way.
