Abstract: In 2010 and 2011, the efficiency of azadirachtin, applied as systemic trunk injections in the trunks of Platanus sp., was tested against Corythucha ciliata. Azadirachtin in the doses of 0.1 and 0.05 g of active ingredient per cm of diameter at breast height was applied in April. It was found that after application of both doses, the count of C. ciliata in plane-tree leaves significantly decreased. In 2010 and 2011, the average counted number of C. ciliata individuals in trees treated with the dose 0.1 g a.i./cm of dbh was 12.9 and 4.9, respectively, and 29.1 and 6.5 individuals, respectively, in trees treated with the dose 0.05 g a.i./cm of dbh, in the control it was 152.3 and 105.8 individuals, respectively.
