Komento only on a blog item (detail page), not category list

Hi, we want to use komento in a joomla blog without extensions like K2 or others. At the blog, we want to show the comments only at the detail pages of an blog-item, not at the category lists themselves. But right now it's shown on both, the category lists and the detail page, too. Can we hide komento on the category lists??? Thanx for helping!
