Lecanicillium aphanocladii – a new species to the mycoflora of Lithuania and a new pathogen of tree leaves mining insects [Lecanicillium aphanocladii – nauja Lietuvos mikofloros rūšis ir naujas medžių lapus minuojančių vabzdžių patogenas pasaulyje]


Popular park and city trees horse chestnut, Aesculus hippocastanum L. and small-leaved linden, Tilia cordata Miller suffer from damages of leaf mining moths, Cameraria ohridella Deschka & Dimic 1968 and Lithocolletis issikii Kumata 1825 (= Phyllonorycter issikii Humber 1822 (both Lepidoptera, Gracillariidae), respectively. In 2010–2011, fungi causing moth caterpillar mortality under field conditions were investigated in Vilnius city, Lithuania. Statistical analyses showed high recovery percentage (30.36 % and 31.92 % from C. ohridella and L. issikii caterpillar cadavers, respectively) of a new fungus, which was thereafter identified as Lecanicillium aphanocladii Zare & W. Gams 2001 based on a morphological characteristics and ITS rDNR sequence, which showed 99 % identity with Aphanocladium aranearum (Petch) W. Gams 1971 GenBank accessions No. AF455489 and AF455405 of ribosomal RNA gene (now renamed as L. aphanockladii).
