The Black Fly Breeding Sites in the Mongolian Part of the Selenge River Basin (Diptera: Simuliidae)

AbstractData from black fly traps in Deep River over the past 5 years indicate that larvicides applied to breeding sites in streams surrounding the town have substantially reduced the numbers of this pest. Very high numbers occurred in 1972, the result of invasion associated with high westerly and northerly winds at a critical period of time or with heavy protective snow cover during the preceding winter. The lowest population levels occurred in 1975, when treatment included a stream near the town which had not been treated previously. The results indicate that with proper stream management it is possible to substantially reduce the nuisance value of black flies in a small northern town.

First Time

The data on black fly fauna in Moldova are absent in the old and modern literature. Overall, 45 black fly species from the genera Prosimulium (four species) and Simulium (41 species) are common both for Romania and Ukraine and expected to be present in Moldova. For the first time cross-sectional entomological survey was conducted in 2018 to detect the breeding sites of Simuliidae in Moldova. Productive breeding sites of black flies were identified in the creek close to the Dniester River section located in Vascauti village, Racovat River sections located in Branzeni and Burlanesti villages. Immature stages of black flies also have been found in the small creeks in Chisinau and Duruitoarea Veche.

SummaryFieldwork on the distribution, habitat preferences and status of birds was conducted in the Bikin River basin, northern Ussuriland, south-east Russia, during May–July 1992,1993,1995,1996 and 1997. The results of this survey combined with data collected during 1960–1990, show the area to be of high conservation priority and one of the most important for the conservation of Blakiston's Fish Owl Ketupa blakistoni, Chinese Merganser Mergus squamatus, Mandarin Duck Aix galericulata and Hooded Crane Grus monacha. This paper reports on all of the 13 threatened and near-threatened breeding species of northern Ussuriland, with special emphasis on their occurrence and status in the Bikin area. Three more species, included in the Red Data Book of Russia, are also briefly discussed. Maps show the distribution of the breeding sites of the species discussed. The establishment of a nature reserve in the lower Bikin area is suggested as the only way to conserve the virgin Manchurian-type habitats (wetlands and forests), and all 10 species of special conservation concern. Monitoring of the local populations of Blakiston's Fish Owl, Chinese Merganser and Mandarin Duck in the middle Bikin is required.
