According to the Office of the State Food and Beverage Service, in places where the quarantine regime was introduced (Goshchansky district, Goshcha village, Babin village - 3.7 hectares and Sarnensky district, Sarny town - 4.5 hectares), the American white butterfly showed the greatest harmfulness.

New pest outbreaks have been seen in neighboring areas of the Rivne region. In August of this year, new outbreaks were identified and a quarantine regime was introduced with respect to the pest in Zdolbunovsky (v. Zdolbitsa, v. Kunin, v. Uyezdtsy) and Sarnensky (v. Remchitsy) districts on a total area of ​​3.4 hectares.

According to experts, in comparison with last year, the harmfulness of the insect has increased significantly due to favorable weather conditions. In 2018, in the Rivne region there were no areas with quarantine restrictions for this pest. And this year, weather conditions contributed to the emergence of new foci of the spread of the American white butterfly and the expansion of quarantined areas.
