Introduction

Dragonflies are well known biocontrol agents and environmental quality indicators. They possess slender abdomen, large eyes short antennae and long wings (Dijkstra and Lewington, 2006). The dragonflies are the earliest along with the most prevalent hemimetabolous amphibiotic and paleopterous insect group and found on all continents excluding Antarctica (Silsby, 2001). Dragonflies are very valuable insects and the study of the fauna is significant for decision making about crops management and environmental protection (Rowe, 2003). Dragonflies also possess medicinal properties in some countries and sympetrum species are used for curing fever (Mitra, 2002). Adult dragonflies are also taken as a minor food item in some countries like Africa, South America and Indonesia where adults are fried in oil or used in soup (Boyd, 2005). The naiads of dragonflies are also used by fisherman to catch a fish (Rowe, 2003). The larvae and adult act as biocontrol agent against different insect pests of medical importance and helps in managing different infectious diseases like dengue, filaria and malaria (Mitra, 2006). Odonates have achieved a focal point of research in various countries specially in the tropical countries (Woodward, 2001).

A lot of work has been carried out to explore species complex of dragonflies and about total of 70 species of dragonflies were reported from different areas of Pakistan (Chaudhry, 2010; Raza, 2016). Information on Khyber Pakhtunkhwa (KP) Province fauna has been poorly collected throughout both studies. Though the existence of infinite natural water reservoirs like rivers lakes snow, streams , ponds favors Anisoptera survival and thus odonatologists are interested from all over word. District Swabi is situated in Khyber Pakhtunkhwa (KP) Province, Pakistan. It lies between the rivers of Indus and Kabul. It is located at 72.47° East longitude, 34.12° North latitude. This area possesses adjustable habitats and infinite resources of water like rivers, springs, canals and streams. District Swabi possess both plain and mountainous areas, along with plenty of habitats supporting dragonflies’ activity for a prolonged time. The area was not explored for taxonomic identification of different dragonflies’ species. Keeping in view all of the above-mentioned facts, a comprehensive survey was carried out to explore Odonata fauna of District Swabi and to study their distribution in unexplored area of Khyber Pakhtunkhwa Province of Pakistan.

Materials and Methods

Study area

A detailed survey was conducted to collect adult dragonflies of District Swabi, Khyber Pakhtunkhwa, Pakistan, during summer seasons of 2015 and 2016. Adult dragonfly specimen were randomly collected from all tehsils of District Swabi covering the whole district. Main localities were Adina L1, Yarhussain L2, Turlandi L3, Dagai L4, Shewa L5, Naranji L6, Azamabad L7, Saleem khan L8, Maneri L9, Shamansor L10, Panjpir L11, Anbar L12, Lahor (Chota) L13, Marghuz L14, Topi L15, Gandaf L16, Ganiichatra L17, Kabghani L18, and Gabasnai L19 as shown in Figure 1.

 

Collection and preservation of adults

The adult dragonflies were collected with the help of aerial net in sunny days from 08 am to 05 pm. The collected specimens were killed in killing jar having ethyl acetate soaked cotton swabs. The killed specimens were taken from jar and placed in triangular paper envelope with their folded wings above the body. Information regarding locality, collector’s name and date of collection was written on the paper envelope while other information like habitat were noted in the notebook. To prevent damage, the collected specimen was kept singly in each envelope. Specimen were properly pinned and the body part was set on appropriate setting board. Dried specimens were transferred to collection boxes, properly labeled and each specimen were tagged. Naphthalene balls and coopex powder were sprinkled in insect boxes to protect them from ants and other museum insect pests.

The collected specimens were identified in National Insect Museum, NARC Islamabad up to species level. The identification of specimens was carried out with the help of literature through Fraser (1933-1934, 1936), Chaudhry (2010) and Zia (2010) up to species level. Identified specimens were deposited in Insect Museum, Department of Entomology, The University of Agriculture, Peshawar and their representative specimen were deposited in NIM (National Insect Museum), NARC, Islamabad for future reference and studies.

Results and Discussion

A total of 347 adult dragonflies specimen were collected from nineteen different localities of district Swabi. The study yielded a total of 23 species from 15 genera under 03 families. In current study, among the three subfamilies, family Libellulidae was found most

abundant with 19 species followed by family Gomphidae with 03 Species and family Aeshnidae with only one species (Figure 2) Species Ictinogomphus angulosus, Burmagomphus sivalikensis, Zyxomma petiolatum were recorded for the first time from district Swabi as well as Khyber Pakhtunkhwa province.

Recording of 23 species under 15 genera and 03 families of Anisoptera from the study region indicates that the region is rich in Odonata diversity. During monsoon the Odonates were abundant in flooded crop-fields, grasslands and swamps, crop-fields ponds and streams. It is very imperative to document that being flying insects, Anisoptera are well known to fly long distances in search of food and best ecological conditions mainly for temperature and humidity preferences. Recording diversity of Odonata species of an area based on the collection of adults, arises doubts on their endemism (Zia et al., 2011). Yousaf (1972), initiated the work on Dragonflies, and identified 46 species belonging to 24 genera of Anisoptrous dragonflies from various localities of Pakistan. Published information about dragonflies at country level has been reported by (Chaudhry, 2010). Anisoptera fauna of KP province remained under explored with very limited records existing at present. Few short-term studies were conducted on dragonflies’ fauna of Khyber Pakhtunkhwa by (Khan et al., 2016; Zada et al., 2016; Sayeb et al., 2015; Perveen et al., 2014; Akhtar et al., 2014; Khaliq and Maula, 1999; Ahmad, 1994; Yousuf, 1972). In all these studies, District Swabi was ignored and no record for Anisopterous species of this important district was available till now. This study opens the door for more faunistic surveys covering the whole province and encourage taking steps toward their protection and survival for pest management.

Conclusions and Recommendations

District Swabi of Khyber Pakhtunkhwa is rich in Odonates fauna. The climate, cropping pattern and topography of this area along with plenty of natural pastures and aquatic marshland support Odonates life cycle and biology.
