AbstractsPavela R., Žabka M., Kalinkin V., Kotenev E., Gerus A., Shchenikova A., Chermenskaya T. (2013): Systemic applications of azadirachtin in the control of Corythucha ciliata (Say, 1832) (Hemiptera, Tingidae), a pest of Platanus sp. Plant Protect. Sci., 49: 27-33.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 planetree 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.

classified as ZIKV seropositive and the remaining 12 (16.7%) as flavivirus seropositive. Eleven of 14 provinces contributed ZIKV positive specimens, ranging from 4.5% of specimens from North Sumatra, Banten, and East Kalimantan to more than 18% of specimens from Central Java. Overall ZIKV seroprevalence in the 1-4 year-old cohort was 9.1%.Conclusion: We have conducted ZIKV serological screening on samples collected from children in representative areas in Indonesia and revealed the seroprevalence of ZIKV in most regions. The data provide evidence of widespread recent transmission and endemicity of ZIKV in the country. This knowledge provides clues for understanding future patterns of Zika virus transmission in nonendemic areas.

Crimean hemorrhagic fever (CHF) is one of the priority infections in the south of the European part of the Russian Federation. Persistently high morbidity rates are retained within the past five year term, with case fatality amounting to 4.3 % on the average. In 2014 registered were 91 CHF cases. Therewith, displayed is the analysis of epidemiological situation on CHF in the territory of Russia in 2014, consolidated are the results of epizootiological surveillance of the CHF natural focus area, represented are the findings of genetic typing of CCHF virus which circulated in Russia in 2014. Using the data on epizootiological monitoring, made has been the forecast of CHF epidemiological situation development for 2015.

крымская геморрагическая лихорадка (кгл)особо опасная природно-очаговая вирусная инфекция, эндемичная для территории юга европейской части россии, характеризующаяся тяжелым течением болезни с высоким уровнем летальности (3-20 %) [1]. природные очаги кгл известны на территории африки, азии, Юго-восточной европы и юга европейской части россии [1, 2]. в 2017 г. случаи заболевания кгл выявлены в иране (120, летальных 8) [6], пакистане (69, летальных 11) [11], омане (9, летальных 3) [10], индии (2) [4, 5], уганде (8, летальных 2) [15], Юар (2) [13, 14], намибии (2, летальный 1) [8, 9], мавритании (3) [7], сенегале (3, 2 заносных случая из мавритании) [7, 12]. рост заболеваемости кгл отмечен в афганистане: в 2017 г. выявлено 237 случаев (41 летальный), в 2016 г.-156 (18 летальных), до 2016 г. в стране регистрировалось от 5 до 50 больных в год [3, 16]. кгл остается одной из наиболее актуальных природно-очаговых инфекций для регионов юга россии. эпидемические проявления кгл в Южном и северо-кавказском федеральных округах (ЮФо и скФо) в период с 1999 по 2017 год зарегистрированы в 10 из 14 субъектов: ростовской, волгоградской, астраханской областях, ставропольском крае, республиках дагестан, калмыкия, ингушетия, крым,

Aim. Analysis of epidemic manifestations of natural-foci infections (NFI), clarification of spectrum of their causative agents, determination of epizootic activity of natural foci in the Crimea Federal District (KFD). Materials and methods. Epizootologic examination of 10 administrative districts of KDF was carried out. 291 pools (2705 specimens) of ixodes ticks and 283 samples of organs of small mammals were studied by PCR method for the presence of DNA/RNA of causative agents of a number of NFI. Results. Morbidity by NFI in KFD was registered by 6 nosologies: Lyme borreliosis, Marseilles fever, leptospirosis, tularemia, intestine yersiniosis and tick-borne viral encephalitis, wherein, transmissive infections made up 91.6%. Circulation of causative agents of Crimea hemorrhagic fever, Q fever, group of tick-borne spotted fever, Lyme borreliosis, human granulocytic anaplasmosis, human monocytic ehrlichiosis, hemorrhagic fever with renal syndrome, West Nile fever, tularemia and leptospirosis was established. Conclusion. Due to activity of natural foci of NFI further monitoring of epidemiologic and epizootologic manifestations of these infections in the Crimea, including using genetic methods of analysis, is necessary for ensuring sanitary-epidemiologic welfare of KFD population.
