| stagewise mortality, ovipositional biology, and egg viability of boophilus annulatus (acari: ixodidae) on boselaphus tragocamelus (artiodactyla: bovidae). | the stagewise mortality, ovipositional biology, and egg viability of the cattle tick, boophilus annulatus (say), on nilgai antelope, boselaphus tragocamelus pallas, was compared with ticks reared on bos taurus (hereford) cattle. mortality was highest during the larval stage on both host species, but larval mortality on nilgai (78.6%) was significantly higher than on cattle (45.6%) hosts. mortality during the nymphal stage was also significantly higher on nilgai (49.3%) than on cattle (13.9%). du ... | 1993 | 8271258 |
