Samples for research were selected in the course of route surveys of plants of the Botanical Garden named after. acad. A.V. Fomin, National Botanical Garden. N. Grishko National Academy of Sciences of Ukraine and parks, squares, street plantations of plane trees in Kyiv. Platanus identification using the lacemaker's bug (Corythucha ciliate Say), uses a light microscope and a smartphone with the «Magnifier Cam software». For the first time, we found damage to the leaves of the plane tree Platanus x acerifolia (Ait.) by the bug Corythucha ciliata Say in Kyiv. This is the northernmost border of the phytophage distribution in Ukraine. The phytophage was found in six of the nine surveyed habitats of Platanus acerifolia (50°41'83" N, 30°56'37" E; 50°43'99"N, 30°51'83"E; 50°26'99" N, 30°94'99" E; 50°26'42"N, 30°32'01"E; 50°39'35"N, 30°50'66"E; 50°38'22"N, 30°47'73"E). The bug was not found in the Botanical Garden named after acad. A.V. Fomin. A high degree of sycamore bug damage was observed on plants growing in habitats. 50°39'35"N, 30°50'66"E (4.7 point) and 50°38'22"N, 30°47'73"E (2.9 point). Bedbugs prefer the south side of the trunk for wintering (72.3% of individuals). The ratio of females and males on the southern side was 2,5/1, on the northern side - 1,7/1. The bug Corythucha ciliata, being under the cork cambium in winter, survives in the natural environment when the temperature drops to -22 °1 (duration - four days). [ABSTRACT FROM AUTHOR] |
