“…It is the most widespread anopheles species in Iran and presents in almost all parts of the country in altitudes 50–2,000 m across all climatic zones including arid to wet climates [ 22 ]. This species has a broad geographical distribution in Asia, Europe and northern Africa, and has been recognized as a malarial vector in these regions [ 23 ].…”

BackgroundMalaria is a major vector-borne disease in tropical and sub-tropical countries caused by Plasmodium infection. It is one the most important health problem in south and southeast of Iran. Since Iran has recently launched to the elimination phase of malaria and vector control is one of the main strategies for elimination, this study was conducted to determine the topographical distribution of malaria vectors in Minab County, one of the important malaria endemic areas in south of Iran.MethodsIn this cross-sectional study, six villages in three topographically different sites namely coastal plain, foothill and mountainous areas were selected by simple random sampling. The anopheline larvae were collected using the standard dipping method. The specimens were identified using a morphology based-key. Statistical analyses were performed using SPSS ver.16 software.ResultsIn total, 3,841 anopheles larvae were collected from 24 larval habitats. They consisted of ten species: Anopheles moghulensis (25.23%), Anopheles stephensi (24.47%), Anopheles dthali (19.14%), Anopheles culicifacies (9.63%), Anopheles fluviatilis (7.52%), Anopheles superpictus (5.62%), Anopheles turkhudi (5.55%), Anopheles pulcherrimus (1.93%), Anopheles multicolor (0.47%), and Anopheles apoci (0.44%). Most species were distributed in different topographies and only An. Stephensi and An. culicifacies, the main malaria vectors in Iran, were significantly associated with the altitude of studied areas. An. moghulensis, An. stephensi and An. dthali were the most widespread species and were, respectively predominant in Coastal plain, foothill and mountainous areas.ConclusionResults of this study have revealed that there are many malaria vectors that are distributed in Minab County and some of them are expected to be predominant in areas with special topographic characteristics. This finding can provide a basis for effective planning and implementation of evidence-based malaria vector intervention strategies towards vector control, which may help in malaria elimination in the study area.

“…According to the newest checklist of Iranian mosquitoes, 64 species representing seven genera occur in the country (Azari-Hamidian, 2007). Five Anopheles species was reported as the proven malaria vectors in southern Iran including; An stephensi, An fluviatilis, An culicifacies, An dthali, An superpictus and one as the suspected, An pulcherrimus (Nejati et al, 2013) Naddaf et al, (2010, 2012 reported the occurrences of theAn. fluviatilis James species U and T in Southern Iran (Naddaf et al, 2010;Naddaf et al, 2012).…”

“…fluviatilis plays a secondary role in the malaria transmission (Moosa-Kazemi et al, 2014). Indoor residual spraying (IRS) and distributed of long lasting impregnated bed nets are considered as the main strategy to control of malaria vectors in Iran during the malaria elimination phase (Nejati et al, 2013). IRS may reduced the population of endophile species of An.…”

“…The repeated use of the same insecticides combined with agriculture pesticide usage has maintained a selection pressure amongst mosquito populations leading inevitably to the development of insecticide resistance in many African malaria endemic countries [ 13 ]. Resistance to several insecticides have also been reported in the Middle East region including DDT resistance in Iran [ 14 ] and pyrethroid resistance in An. stephensi in Dubai [ 15 ], although such monitoring is less developed than in the sub-Saharan or East African region (see the current status of insecticide resistance worldwide on the IR mapper interactive tool [ 16 ]).…”

BackgroundInsecticide resistance seriously threatens the efficacy of vector control interventions in malaria endemic countries. In Afghanistan, the status of insecticide resistance is largely unknown while distribution of long-lasting insecticidal nets has intensified in recent years. The main objective of this study was thus to measure the level of resistance to four classes of insecticides in provinces with medium to high risk of malaria transmission.MethodsAdult female mosquitoes were reared from larvae successively collected in the provinces of Nangarhar, Kunar, Badakhshan, Ghazni and Laghman from August to October 2014. WHO insecticide susceptibility tests were performed with DDT (4 %), malathion (5 %), bendiocarb (0.1 %), permethrin (0.75 %) and deltamethrin (0.05 %). In addition, the presence of kdr mutations was investigated in deltamethrin resistant and susceptible Anopheles stephensi mosquitoes collected in the eastern provinces of Nangarhar and Kunar.ResultsAnalyses of mortality rates revealed emerging resistance against all four classes of insecticides in the provinces located east and south of the Hindu Kush mountain range. Resistance is observed in both An. stephensi and Anopheles culicifacies, the two dominant malaria vectors in these provinces. Anopheles superpictus in the northern province of Badakhshan shows a different pattern of susceptibility with suspected resistance observed only for deltamethrin and bendiocarb. Genotype analysis of knock down resistance (kdr) mutations at the voltage-gated channel gene from An. stephensi mosquitoes shows the presence of the known resistant alleles L1014S and L1014F. However, a significant fraction of deltamethrin-resistant mosquitoes were homozygous for the 1014L wild type allele indicating that other mechanisms must be considered to account for the observed pyrethroid resistance.ConclusionsThis study confirms the importance of monitoring insecticide resistance for the development of an integrated vector management in Afghanistan. The validation of the kdr genotyping PCR assay applied to An. stephensi collected in Afghanistan paves the way for further studies into the mechanisms of insecticide resistance of malaria vectors in this region.Electronic supplementary materialThe online version of this article (doi:10.1186/s12936-016-1149-1) contains supplementary material, which is available to authorized users.
