The title is "New perspectives on Varroa". One chapter deals with Varroa biology. There is quite a bit of information available about Varroa mites but it is widly scattered in scientific journals and lot of it is also published in German-unfortunately. This means that it is "lost" to the audience in the USA. Sad but true. Good luck in fighting this new bugger in your hives Hans
