Objective:To identify the biological forms,sporozoite rate and molecular characterization of the Anopheles stephensi(An.stephensi)in Hormozgan and Sistan-Baluchistan provinces,the most important malarious areas in Iran.Methods:Wild live An.stephensi samples were collected from different malarious areas in southern Iran.The biological forms were identified based on number of egg-ridges.Molecular characterization of biological forms was verified by analysis of the mitochondrial cytochrome oxidase subunit I and II(mtDNA-COI/COII).The Plasmodium infection was examined in the wild female specimens by species-specific nested-PCR method.Results:Results showed that all three biological forms including mysorensis,intermediate and type are present in the study areas.Molecular investigations revealed no genetic variation between mtDNA COI/COII sequences of the biological forms and no Plasmodium parasites was detected in the collected mosquito samples.Conclusions:Presence of three biological forms with identical sequences showed that the known biological forms belong to a single taxon and the various vectorial capacities reported for these forms are more likely corresponded to other epidemiological factors than to the morphotype of the populations.Lack of malaria parasite infection in An,stephensi,the most important vector of malaria,may be partly due to the success and achievement of ongoing active malaria control program in the region.

Objective: To determine the synergists action of piperonyl butoxide(PBO) and S,S,Stributyl phosphorotrithioate(DEF) on toxicity of carbamate insecticides against Blattella germanica in Tehran city.Methods: In the current study, German cockroach strains were collected from several hospitals and dormitories in Tehran.At the beginning, different concentrations of bendiocarb and carbaryl(insecticides belong to carbamate group) were determined by surface contact on a susceptible strain.Then, the level of susceptibility and type of resistance mechanisms in the collected strains from contaminated sites to the aforementioned insecticides were studied by using PBO and DEF synergists with different insecticide ratios to synergist(1:0, 1:1, 1:2, 1:3).Results: The DEF synergist along with bendiocarb and carbaryl completely eliminated the resistance in all strains but PBO did not completely eliminate the resistance in the strains of Mofid, Alvand, Valiasr hospitals and Shariati dormitory.Generally, the impact of DEF was observed in the removing resistance more than PBO.Conclusions: In most of these strains, resistance to bendiocarb and carbaryl is completely eliminated by DEF, showing a very high role of estraze enzymes in resistance to bendiocarb and carbaryl.But in most strains PBO does not remove the resistance because other mechanisms, such as reduced cuticle penetration and insensitivity to the acetylcholine esterase enzyme, may be involved.

Objective: To determine the susceptibility status of Anopheles maculipennis(An. maculipennis) against the major insecticides used in the health sectors in West Azarbaijan Province, Northwestern Iran.Methods: Unfed 3-5 days old adult females of An. maculipennis were collected across the West Azarbaijan Province and were subjected to evaluation of their susceptibility following World Health Organization recommended protocol against six insecticides(permethrin, deltamethrin, propoxur, bendiocarb, malathion and dieldrin) belonging to four different classes. Results: In this study, 916 specimens of An. maculipennis were examined against the insecticides which indicated that An. maculipennis was tolerant to permethrin, deltamethrin and dielderin, but displayed resistance against propoxur, bendiocarb and malathion. Conclusions: The pattern of resistance in An. maculipennis could be attributed to the agricultural landscapes, agricultural pesticides used and the exposure of the mosquitoes to insecticides. Logical cooperation is needed between the agriculture and health sectors to ensure the judicious use of pesticides in each sector and the management of probable resistance.

Objective:To determine tick infestation of domestic ruminants and their infection to ovine theileriosis in northern Iran.Methods:About 425 domestic ruminants in Ghaemshahr city in northern Iran were inspected for tick infestations.Twenty tick specimens(13 females and 7 males) of Rhipicephalus sanguineus(R.sanguineus).the most common lick in the study area, were tested by PCR amplification against 18s rRNA genome of Theileria spp using specie specific primers and then the PCR products were sequenced for species identification In comparison with data base available in GenBank.Results:About 323 ticks were collected from 102 animals(88 sheep,12 goats and 2 cattle).The prevalence of ticks infesting animals was R.sanguineus(82.35%), Rhipieeplialus bursa(R.bursa)(0.3%),Ixodes ricinus(I.ricinus)(15.2%),Boophilus annulatus (B.annulalus)(1.2%).Haemaphxsalis punctata(H.punctata)(0.3%) and Haemaphysalis numidiana(H.numidianu)(0.6%).Eleven(55%) tick specimens were PCR positive against genome of Theileria ovis(T.avis).Sequence analysis of the PCR products confirmed presence of T. oris in one R.sanguinus.Conclusions:This is the first report of tick infection to T.oris in Iran. Due to dominant prevalence of R.sanguineus as well as its infection to T.oris,it is postulated this tick is the main vector of ovine theileriosis in northern Iran.
