Lime common (Tilia cordata Mill.) and its invasive phytophage mole-variegated (Phyllonorycter issikii Kumata)

In 2012–2015 in Kiev dangerous invasive species phytophage was marked and defined — mole zygaenidae lime, which has been spreading for recent years in conditions of the Kyiv region and other regions of Ukraine. Mole zygaenidae lime (Phyllonorycter issikii Kumata), Lepidoptera, Gracillariidae Toshio Kumata was described firstly in 1963. A phytophage fed predominantly lime cordata. Butterflies of second and third generations overwinter in cracks in the bark of fodder plants. The first butterflies were by on the colored glue traps in the third week of April with the average daily temperature above + 10°C. It is noted that the extent of damage of lime becomes more aggressive, high and growing over the years. As a result of studies it was found the lime leaves, which marked almost 70% min leaf plate. It was established that in the conditions of Kyiv the stable full development of three generations of phytophage happens. It was proved that the multiplication factor of this type of phytophage during the growing season of plants growing. Yet, as wintering stage mole zygaenidae lime (adults) are quite sensitive to changes in temperature in a city, multiplication factor of the first generation there is very low (within 0.14–0.19). Using the color traps to monitor phytophage showed that the most attractive among the tested colors are red and green. It is proposed continue to conducing a thorough and systematic monitoring of this type of phytophage to prevent the expansion of its range.
