abstract background: zoonotic cutaneous leishmaniasis (zcl) is one of the most important vector-borne diseases in iran. wild rodents play as a reservoir. the main aim of this study was to determine spatial analyses of the relationship between rodent’s active burrows and incidence of zcl in golestan province, north east of iran . methods : the cross-sectional study was conducted in 59 rural dist...
Ucides cordatus is an abundant mangrove crab in Brazil constructing burrows of up to 2 m depth. Sediment around burrows may oxidize during low tides. This increase in sediment-air contact area may enhance carbon degradation processes. We hypothesized that 1) the sediment CO2 efflux rate is greater with burrows than without and 2) the reduction potential in radial profiles in the sediment surrou...

during a search of burrows for the purpose of capturing rodents in 1972, a number of soil samples were inspected for the collection of sand fly larvae. in this study, a total of 472 plastic bags of soil samples were collected from different depths of 30 rodent burrows. fourteen of these samples were found positive, from which 27 larvae were removed. most of the larvae were found in the depths o...
Tsetse flies Glossina pallidipes Austen and G. morsitans morsitans Westwood deposit their larvae in warthog burrows, in August-November, at Rekomitjie Research Station, Zambezi Valley, Zimbabwe. Artificial burrows, made from 200-l steel drums, were used to sample these flies and to collect their puparia. Sand-filled plastic trays in the burrows served as a substrate for larval deposition. The s...
Four species of ticks were retrieved from burrows of 64 multimammate rats, Mastomys erythroleucus (Temminck), 55-gerbils, Taterillus gracilis (Thomas) or T. pygargus (Cuvier), 13 Nile rats, Arvicanthis niloticus (DeMarest), and five Geoffroy's ground squirrels, Xerus erythropus (Geoffroy) from May 1987 through August 1988 at two study sites in northern Senegal. Ornithodoros sonrai Sautet & Witk...
On Tereia Island, Rangiroa Atoll, 14,321 land crab burrows were treated with the copepod Mesocyclops aspericornis from January to June 1986, to control larvae of Aedes polynesiensis marks. In October 1987, the entire island of Tereia was retreated (17,300 burrows), and the neighboring island, Voisin, was left untreated as a control. From 5 to 15 mo after treatment, burrows with M. aspericornis ...
The gopher tortoise, Gopherus polyphemus Daudin, is endemic to the southeastern US, where its populations are declining primarily due to habitat destruction. Tortoises are preyed upon by many species, including the red imported fire ant, Solenopsis invicta Buren, a destructive exotic species now common throughout the tortoises’ entire range. We surveyed ants using tuna bait at 154 G. polyphemus...
Previous studies suggest that rodent burrows, a proxy for rodent population are important for predicting plague risk areas. However, studies that link landform, surface attributes and rodent burrows in the Western Usambara Mountains in Tanzania are scanty. Therefore, this study was conducted in plague endemic area of the Western Usambara Mountains in northern, Tanzania, to explore the relations...
