A (Young, 1972; Endris, 1982). Site B was selected on the basis of 

 1971 light trap collection records of 237 females from a single light 

 trap (Perkins, 1982). The remaining sites E, F, G, and H were the 

 actual home environs of confirmed leishmaniasis patients. 



Surveys for potential sand fly vectors were conducted at all sites 

 during the course of the study. Emphasis was placed on qualitative 

 rather than quantitative sampling; no attempt was made to estimate 

 sand fly population densities. 



Site A . Garner State Park, Concan, Uvalde County, Texas (4-28 

 June, 1982; 19-30 September, 1983; Fig. 2-5 and 2-6). This state park 

 is located 50 km north of Uvalde in the Frio River valley. It is 

 situated on the southern edge of the Edwards Plateau, on the Bal cones 

 Escarpment, which separates the plateau from the Nueces plains to the 

 south. The habitat is characterized by grassy meadows dotted with 

 cedar ( Juniperus sp.), live oak ( Quercus virginiana ), acacia ( Acacia 

 sp.), pecan ( Carya il 1 inoensis ), mesquite ( Prosopis Jul iflora ), and 

 elm ( Ulmus crassifol ia ), with bald cypress ( Cupressus arizonica ) 

 bordering the Frio river. The park is surrounded by steep rocky 

 hills, the slopes of which are covered with cedar, wild cherry ( Prunus 

 serotina ), persimmon ( Diospyros texana) , madrone ( Arbutus texana ), 

 and other Hill Country shrubs. Potential mammalian hosts for sand 

 flies include white tail deer ( Odocoileus virginianus ), coyote ( Can is 

 latrans ), fox ( Vulpes sp.), bobcat ( Lynx rufus ), racoon ( Procyon 

 lotor ), porcupine ( Erethizon dorsatum ), skunk ( Mephitis sp.), opossum 

 ( Didelphus marsupial is ), armadillo ( Dasypus novemcinctus ) , jack rabbit 

 ( Lepus cal ifornica ), cottontail rabbit ( Sylvilagus floridanus ), and a 

 variety of rodents (Texas Parks and Wildlife Department, 1982a; Raisz, 

 1954; Kuchler, 1975).
