The systematic position of the genus Chirobia Fain, 1959 (Astigmata: Sarcoptidae) with a description of Chirobia harpyionycteris n. sp. from the Old World fruit bat Harpyionycteris whiteheadi (Chiroptera: Pteropodidae)

A new species of Chirobia Fain, 1959, C. harpyionycteris n. sp., parasitic on the Old World fruit bat Harpyionycteris whiteheadi (Chiroptera: Pteropodidae) is described and illustrated, with notes on its ecology. The assemblage of the genera Chirobia, Teinocoptes Rodhain, 1923 and Tychosarcoptes Fain, 1976 forms a monophyletic group within the family Sarcoptidae. Within this group, Chirobia is monophyletic, with a sister group relationship between C. harpyionycteris and the assemblage of all previously described Chirobia species. The status of Teinocoptes remains uncertain, but the available evidence suggests that this genus may be paraphyletic.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43838/1/11230_2004_Article_BF00012193.pd

Importance of ticks and their chemical and immunological control in livestock

The medical and economic importance of ticks has long been recognized due to their ability to transmit diseases to humans and animals. Ticks cause great economic losses to livestock, and adversely affect livestock hosts in several ways. Loss of blood is a direct effect of ticks acting as potential vector for haemo-protozoa and helminth parasites. Blood sucking by large numbers of ticks causes reduction in live weight and anemia among domestic animals, while their bites also reduce the quality of hides. However, major losses caused by ticks are due to their ability to transmit protozoan, rickettsial and viral diseases of livestock, which are of great economic importance world-wide. There are quite a few methods for controlling ticks, but every method has certain shortcomings. The present review is focused on ticks importance and their control
