Propagation, trophic connection, and phenology of Metcalfa pruinosa (Say, 1830) (Auchenorrhyncha: Hemiptera) in the Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine.

Abstract

The larvae of the invasive species Metcalfa pruinosa (Say, 1830) were found on the territory of the botanical-geographic plot "The Far East" in the Gryshko National Botanical Garden, National Academy of Sciences of Ukraine, in Kyiv for the first time in May 2016. During five years of observations, the insect managed to expand its range to other areas of the Botanical Garden and adjacent territories, where it reached a high population density. It is still the northernmost point of the insect's detection on the territory of Ukraine. The range of M. pruinosa host plants was examined. The species lives on a large number of ornamental and synanthropic plants and fruit and vegetable crops, which belong to 80 species from 55 families. The most susceptible to colonization by citrus cicada are the families Rosaceae-18 species, Aceraceae-5 species, and Oleaceae-4 species of plants. It has been found that M. pruinosa develops one generation per year. The appearance of cicada larvae is observed in the first ten days of May. The first imagoes are recorded in early or mid-July, depending on the meteorological conditions of the year. The complete disappearance of imagoes happens at the end of August. The insect's development is limited by a minimum air temperature of 17-20°C. In the future, it will be necessary to monitor and analyze comprehensively various factors that may affect the emergence, propagation, and survival of M. pruinosa on new territories.
