In September - October 1998 we made an extensive survey in southwest Tibet to study numbers, distribution and social structure of the kiang population in this remote part of its range. Kiangs were sighted between 29º 40’ and 32º 50’ N, and 81º- 86º E. They preferred broad flat valleys with lakes at an altitude from 4,000 up to 5,000 m. Small kiang groups and solitary animals were sighted in Transhimalaya. There were no kiangs in Tsangpo (Brahmaputra) River valley, in the sand desert near Ali and in the Clay Mountains near Tsada. Seven old kiang corpses were found along …

Physocephala pusilla Meigen (Diptera: Conopidae) was found to be a dangerous endoparasitoid of the alfalfa leafcutter bee Megachile rotundata F. (Hymenoptera: Megachilidae) in Mongolia. The conopid fly parasitizes adults and causes their early death. In 1989 and 1990, 16% and 15% respectively of the M. rotundata females were found dead in front of the bee shelter. However, the number of bees (females and males) dying in the field is unknown. These bees cause a contamination of the alfalfa fields due to an increase of the conopid population. Therefore, Ph. pusilla becomes a serious problem for the management of M. rotundata …
