PREVALENCE OF CUTEREBRID (DIPTERA: CUTEREBRIDAE) PARASITISM AMONG BLACK-TAILED JACKRABBITS IN SOUTHERN TEXAS

摘要

Twenty-two of 80 (27.5%) adult black-tailed jackrabbits (Lepus californicus) examined in southern Texas from March to July of 1996 were infected with Cuterebra sp. larvae. The number of larvae per jackrabbit ranged from 0 to 3 with a mean abundance of 0.5 ± 0.1 (SE) larvae per jackrabbit. More females (45.2%) were infected than males (7.9%) and prevalence of infection was greater (P < 0.001) in gravid females (60%) than non-gravid females (23.5%). Locality of infection on the host included the genital, flank and shoulder regions.
