I have installed plugin AVH Extended Categories.

Previuosly I added in CSS insert next code (from forum):

/* Setup bullets for LI items on sidebar */
div.widget widget_extended-categories ul {
list-style-type: none !important;
}

div.widget ul li a:link,
div.widget ul li a:visited,
div.widget ul li a:active,
div.widget ul li a:hover {
border-left: 0 !important;
padding-left: 0 !important;
}

/* Normal bullet for subtitle*/
div.widget ul ul li {
border-left: 0 !important;
padding-left: 15px !important;
background: url(/wp-content/themes/atahualpa/images/bullets/circle-in-circle-blue12x12.png) no-repeat 0 3px;
}
/* On hover bullet for subtitle*/
div.widget ul ul li:hover,
div.widget ul ul li.sfhover {
border-left: 0 !important;
padding-left: 15px !important;
background: url(/wp-content/themes/atahualpa/images/bullets/xxxcircle-in-circle-brown12x12.png) no-repeat 0 3px;
}
/* Normal bullet for title*/
div.widget ul li {
border-left: 0 !important;
padding-left: 15px !important;
background: url(/wp-content/themes/atahualpa/images/bullets/XXXarrow_right-1.gif) no-repeat 0 3px;
}
/* On hover bullet for title*/
div.widget ul li:hover,
div.widget ul li.sfhover {
border-left: 0 !important;
padding-left: 15px !important;
background: url(/wp-content/themes/atahualpa/images/bullets/xxx.png) no-repeat 0 3px;
}


Now bullets disappeared.
I have found the code for Left Sidebar and tried to solve the problem without assistance, but couldn't.

<!-- Left Sidebar -->
<td id="left">

<div id="extended-categories-4" class="widget widget_extended-categories"><!-- AVH Extended Categories version 2.3.3 | http://blog.avirtualhome.com/wordpress-plugins/ --><div class="widget-title"><h3>ЮВА</h3></div><ul> <li class="cat-item cat-item-7 current-cat"><a href="http://webshus.ru/?cat=7" title="View all posts filed under Бирманское">Бирманское</a>
