There have been unexpected and alarming colony losses in different regions of the world in the past few years (reviewed in Oldroyd, 2007; EFSA, 2008; see also vanEngelsdorp et al., 2008). Concurrent with those in the US, high colony losses also were reported in Turkey (Giray et al., 2007). Health of honey bees in Turkey is of general importance, both because of native honey bee biodiversity (see Bodur et al., 2007; reviewed in Kence, 2006) and a high number of domestic colonies (> 5 million; FAOSTAT, 2008), which is second only to China. We investigated the extent and causes of losses in Turkey using a questionnaire study, which was conducted in 2007 and covered the three previous years. This report includes analyses of 288 questionnaires reporting on 35 597 colonies and, in contrast with a preliminary report (88 questionnaires; Giray et al., 2007), provides a broad representation of geographical regions, a better estimate of regional colony losses, and novel insights such as on colony collapse disorder (CCD) symptoms and losses. Questionnaires were collected through an academic and trade journal for beekeeping (U. Bee J.), local beekeeping organizations, their field representatives, the internet, and Turkish mail. Returned questionnaires (see supplemental information S1) included names and contacts of beekeepers. The results were coded and analyzed by different authors
