Present study was conducted during period (March to September 2018) on the cattle ticks (Acari: Ixodidae) that infested on sheep goat ears in Alnnajaf Province. Two species of hard ticks were identified Boophilus annulatus and Rhipicephalus sanguineus, the species B. annulatus was most predominant than the species R. sanguineus at percentages (92.14, 7.85) % respectively. Of these ticks, 105 were female, 38 were males, 124 and 144 were nymph females and males respectively and there were not larva observed. The monthly samples of hard tick B. annulatus revealed that higher monthly samples during September, but lower monthly samples during June and July. Results of Scanner Electron Microscope analyses showed more distinguished fine characters of B. annulatus that differentiated from R. sanguineus, however both species were lived together on sheep and goat.

The present study was investigated the biological activity of ethanolic leaf extract of Ipomoea carnea, as well as cool and boiled aqueous extracts for investigating toxic affect against, 2nd, and 4th instar larvae of the laboratory reared mosquito species Culex quinquefasciatus after 24, 48 and 72 h of exposure. The tested larvae of Cx. quinquefasciatus were exposed to four concentrations (5, 2, 1 and 0.5 mg/ml) of crude ethanol leaf extract for different time durations. Results were demonstrated that ethanolic leaf extract at concentrations 5 and 2 mg/ml of I. carnea affected the mortality of second and fourth instar larvae it reached 100% after 24 h from treatments. Aqueous extracts of I. carnea leaves also lead to increased mortality rates of second and fourth larvae after 72h, at 50 mg/ml for cool and boiled aqueous extracts the mortality rates were increased into 90 and 95 % respectively. The present study showed that I. carnea leaves extracts have larvicidal activity against filarial vector mosquito Cx. quinquefasciatus.
