Phthorimaea operculella in Russia
Although deleted from the EPPO A2 list in 1991-09, Phthorimaea operculella is considered as a quarantine pest in Russia and other former Soviet Republics. It was first found in USSR in 1938 at Poti (now in Georgia), but the outbreak was eradicated in two years. The species appeared again in Krym (Ukraine) and outbreaks have since been recorded in several areas of Ukraine (Odessa, Kherzon, Zaporozje, Donetsk, Dnepropetrovsk) in the republics of Abkhaziya and Adzhariya (now in Georgia) and in the far-southern Russian province of Krasnodar. The pest is said to have no potential in regions with an annual mean isotherm less than 10 øC. It is absent from most of Russia and from the Central Asian Republics. A 3 km isolation zone is established around any outbreak.
