Abstract A research study was conducted to determine the species composition, relative abundance and seasonal Mir Manzar Ud Din variation of mosquito fauna of District Upper Dir in 2014. The mosquito species recorded were Culex Department of Entomology, the quinquefacitus, Culex mimeticus, Culex theileri, Anopheles maculates, Anopheles stephensi, Anopheles University of Agriculture, annularis, Aedes albopictus, Aedes shortii and Culiseta longiareolata. The results revealed that at Brawal Peshawar, Pakistan. Cx. quinquefacitus dominated the other species (30.21%) while Ae. shortii was least abundant (3.24%). At Dir city, Cx. mimeticus was highly abundant (27.87%) while Ae. shortii was least abundant (3.24%). Sajjad Hussain At Sheringal Cx. quinquefacitus dominated (26.25%) while Cu. longiareolata least abundant (0.79%). At Department of Entomology, the Warai An. maculates was highly abundant (32.86%) while Ae. albopictus least abundant (3.09%). The University of Agriculture, present results might be helpful in devising pest management techniques against the mosquito species of Peshawar, Pakistan. District Dir Upper.

Introduction Mosquitoes are vectors for a number of infections like malaria, dengue, yellow fever etc., Walija Fayaz which affect millions of people annually. Several factors affect the role of mosquitoes as Department of Entomology, the vectors and in disease transmission [1]. Mosquitoes are distributed worldwide, where they University of Agriculture, [2] Peshawar, Pakistan. breed in a variety of habitats . Mosquitoes are spatially and temporally distributed on the [3] basis of species, climatic conditions and environment . Muhammad Saeed Mosquito larval distribution is greatly affected by several factors such as elevation, water Department of Agricultural movement, water condition (polluted, fresh etc.), water temperature, vegetation, types of water Sciences, University of Haripur, source etc. [4]. Mosquito oviposition, development of larva, adult emergence and many other Haripur, Pakistan. processes take place in larval habitats, which play an important role in determining adult [5] Abid Farid distribution and abundance . Entomology Section, ARI Earlier researchers had carried out mosquito faunistic studies in Khyber Pakhtunkhwa, e.g. in Tarnab, Peshawar-Pakistan. Kohat–Hangu valley [6], Gilgit [7], Abbottabad [8] and Peshawar valley and adjacent areas [9] to determine species composition and relative abundance of mosquitoes. Ruidar Ali Shah [10] Entomology Section, ARI There are about 3,500 species of mosquitoes in the world . Mosquito transmitted diseases Tarnab, Peshawar-Pakistan. like malaria, dengue fever and filariasis cause enormous life threatened problems across the world [11]. Mosquitoes’ adult females lay eggs in water or near to water’s edge. Two species of Anopheles, An. stephensi and An. culicifacies are considered to be mainly responsible for the transmission of malaria in Pakistan. An. culicifacies is thought to be the primary vector, especially in rural areas, whereas An. stephensi is considered to be of secondary Importance in rural areas and only partially responsible for urban malaria transmission [12, 13, 14], however, An. stephensi is an important vector in other parts of its range, such as the Persian/Arabian Gulf [15, 16], KP province of Pakistan and eastern Afghanistan [17, 18, 19]. An stephensi being the main malaria vector in KP is evident in a study [20] where they demonstrated that Plasmodium falciparum malaria cases in the KP peaked in October, when An. culicifacies had completely disappeared but An. stephensi was still present. Mosquitoes are responsible for the transmission of various pathogens, such as viruses, bacteria, protozoans and nematodes. Mosquito vectored diseases include malaria, Correspondence: chikungunya, filariasis, dengue fever, West Nile virus, encephalitis, tularemia and yellow Imtiaz Ali Khan fever. Various species of mosquitoes are estimated to transmit various types of diseases to Department of Entomology, the more than 700 million people annually in Africa, South America, Central America, Mexico, University of Agriculture, Russia, and much of Asia, with millions of resultant deaths. At least two million people Peshawar, Pakistan. annually die of these diseases, and the morbidity rates are many times higher still [21]. ~ 455 ~ Journal of Entomology and Zoology Studies Dengue fever is increasingly becoming an epidemic in entomological forceps.

Materials and Methods Burma” [24]. The identification was made up to species level. 2.1 Study Area Description Identification work was carried out at the Entomology District Upper Dir is one of the 25 districts in Khyber Laboratory of the University of Agriculture, Peshawar and Pakhtunkhwa Province of Pakistan. The district is spread over Department of Zoology, Shaheed Benazir Buttho University 3,699 square kilometers. It is situated at Latitude 35o 06 51” N Sheringal, Dir. The identified species were then labeled, and Longitude 72o 01 59” E. The climate of Upper Dir is cold mounted and pinned. These labeled species were preserved in and damp. Its mountains are usually covered with snow and the insect collection box and deposited at the Entomology receives snow fall in the months of December, January and Museum of the University of Agriculture, Peshawar. February. The average rainfall in the district is 700 mm and There was no published information regarding species the temperature varies from -6 oC to 38 oC [23]. composition and abundance of mosquitoes in District Upper Dir. With the aim of contributing to this knowledge, species 2.2 Research Methodology composition and relative abundance of mosquito species were The research study was conducted from April to November investigated id District Dir Upper in 2014. 2014. Adult mosquitoes were collected from four localities; Barawal, Sheringal, Wari and Dir City. The mosquitoes were 3. Results and Discussion collected by means of hand net, aspirator and light trap.

Sampling was regularly made two times in a month of District Dir Upper is given Table 1. It is clear from the for 3-4 hours each time. The collection was made from 7:00 results that out of 278 samples collected at Brawal, Cx. am to 9:00 am and 5:00 pm to 7:00 pm regularly for three days quinquefacitus was the dominant species (84 number, 30.21%) in a weak. and Ae. shortii was the minor species (9 number, 3.24%). At Adult mosquitoes were collected indoor as well as outdoor. Dir City, out of 226 samples collected 63 (27.87%) were that Indoor collection was made from homes and cattle-sheds. of Cx. mimeticus and 3 (1.33) of Ae. shortii. At Shiringal, out Outdoor collection was made from plants, water habitats and of 381 samples collected An. maculates was found in higher water-containing automobile tires. During indoor collection number of 101 (26.50%) and Cu. longiareolata in lower pyrethrum-spray method was used. Indoor resting mosquitoes number of 3 (0.79). Of the total no. of 356 samples collected at were sprayed with pyrethrum. Paper sheets were spread before Warai, higher number of 117 (32.86%) were that of An. spraying. Mosquitoes were collected from sheets by using maculates and lower number of 11 (3.09%) of Ae. albopictus. Table 1. Number and percent of mosquito species in District Dir Upper during 2014.
