tick are considered as the main vector for transmission of various diseases to human being. this study was carried out to investigate the fauna of species belonging to two families of ticks, ixodidae and argasidae in west azerbaijan province, iran. a total number of 62 villages were selected randomly, from the study area 3278 ticks were collected with cluster sampling method, after collection t...

BACKGROUND:Ticks are obligatory blood sucking arthropodsthat can transmit important pathogens. OBJECTIVES: Thedistribution and diversity of ticks fauna were last studied in the northof Iran in 2007. Mazandaran province has a humid climate, whichis favourable to animal husbandry such as sheep breeding. Due tohumid climate, the likelihood of exposure to tick infestation isincreasing. The aim of t...

b a ckground: a survey on tick species composition was carried out in golestan province iran during year 2010–2011.the aim was to determine tick species parasitizing domestic ruminants and their seasonal population dynamics. methods: a total of 124 sheep, 92 goats, 84 cattle, 74 camels and 12 horses in several villages were inspected for tick infestation. the collected ticks preserved in 70% al...

In laboratory bioassays we tested the predatory capacity of the copepod Mesocyclops annulatus on Aedes aegypti and Culex pipiens larvae. A single adult female of M. annulatus caused 51.6% and 52.3% mortality of 50 first instar larvae of Ae. aegypti and Cx. pipiens respectively, in a 72 h test period. When alternative food was added to the containers, mortality rates declined to 16% and 10.3% fo...

A total number of 450 blood samples were collected from 45 different randomly selected cattle herds. Light microscopic examination of blood smears revealed Babesia spp. infection in 4.2%, while 8.9% of blood samples were positive using PCR. Upon multiplex-PCR (mPCR), B. bigemina and B. bovis infections were detected in 37/40 (92.5%) and 3/40 (7.5%) samples, respectively. 530 ticks of 10 Ixodid ...

Factors that directly impact horizontal transmission of the microsporidium Amblyospora albifasciati to its intermediate copepod host, Mesocyclops annulatus were examined in laboratory bioassays. Results were evaluated in relation to life history strategies that facilitate persistence of the parasite in natural populations of its definitive mosquito host, Ochlerotatus albifasciatus. A moderately...

We evaluated the potential of Mesocyclops annulatus as a control agent of Aedes aegypti in La Plata city (Argentina). Mosquito larval survivorship due to predation by these copepods was estimated at weekly intervals during the oviposition period of A. aegypti. Mean weekly A. aegypti larval survivorship in cylindrical plastic containers (12 cm height and 11 cm diameter) with copepods was signifi...
