Introduction

Fruit flies belong to family Tephritidae: the largest family of order Diptera (Drew, 1989), with more than five thousand described species worldwide. Approximately 1400 species of fruit fly develop in fleshy fruits (Norrbomet et al., 1997). These are found in almost all habitats with appropriate plant life all over the world ranging from rainforest to open savannah (Drew, 1989; De Meyer et al., 2010). These medium sized flies with coloured wings cause damage to wide variety of fruits, vegetables and other plant parts (White and Elson-Harris, 1992; Agarwal and Sueyoshi, 2005; Prabhakar et al., 2012). About 250 of these species are causing severe damage and achieved pest status by feeding on plants of economic importance, however, about seventy species of fruit flies are considered major agricultural pests and others are minor pests (White and Elson-Harris, 1992). In Pakistan fruit flies are also serious pests causing losses at the farm level and with added losses to traders, exporters and retailers. Without control losses caused by fruit flies have been estimated to be 21% for fruits and 24 % for cucurbits (Stonehouse et al., 1998). Bactrocer zonata (Saunders) has been recognized as a serious pest of fruits like citrus, mango and guava in Pakistan with an estimated 50 to 55 % infestation in guava only (Syed, 1970). B. zonata has been observed as serious pest of guava, musk melon and cucumber in different areas of Baluchistan, Pakistan (Anonymous, 2002). Two fruit fly species B. cucurbitae (Coquillett) and B. zonata are most notorious and widespread pest all over the country. In Pakistan B. zonata is abundant in most areas of Baluchistan, Sindh, and Punjab, also recorded from Islamabad and Peshawar hill (Sarwar, 2006).

The genus Dacus Fabricius (Diptera: Tephritidae: Dacini) is also one of the most economically important fruit flies (White and Elson-Harris, 1992). There are about two hundred and forty eight Dacuss species most of which show a strong preference for attacking the pods of Asclepiadaceae and Apocynaceae, or the fruits and flowers of Cucurbitaceae (Drew and Romig, 2013). Majority of Dacus species are distributed in the African continent nevertheless several species are also found in the Indian Subcontinent, Southeast Asia, Australia and the Pacific (Drew and Romig, 2013). Dacus (Callantra) longicornis Wiedemann has a widespread distribution across Southern Asia and Southeast Asia and attacks Cucurbitaceae species (Prabhakar et al., 2012). Despite widespread distribution of D. longicornis in Southern and Southeast Asia very limited studies focused on D. longicornis are available except for taxonomy and first record in some countries and areas (Prabhakar et al., 2012; Khan, 2009).

The knowledge of the diversity, as well as the time of population outbreaks of a particular species of Tephritoidea with economic importance, is a prerequisite for the establishment of integrated pest management strategies of fruit fly populations (Ronchi-Teles and Silva, 2005). It appears that as a result an accurate knowledge of the fly pest species in this region would play a significant role to the current understanding of Dacinae biogeography. Though Pakistan is an important strategic power located in South-east Asia, but its fruit fly fauna has been poorly studied in comparison to other neighbouring countries of the region. (Norrbom et al., 1999; Wang xj et al., 2002; Drew, 2004).

Materials and Methods

Study site

The state of Azad Jammu and Kashmir lies between longitude 730 to 750 and latitude 330 to 360 with total area of 5134 square miles (13,297 square kilometres). The altitude varies from 2500ft to 9000ft above sea level and crops are cultivated up to 8000ft. The climate of Poonch division is subtropical to temperate. The temperature ranges between 3.3 to 46.6°C and average rain fall is 507.7 mm per year. The present study was conducted in eight different localities (Rawalakot, Kharick, Ban bake, Jandali, Pakhar, Hajera (Kakuta, Mandhol), Bagh (Harighel) of Poonch division of Azad Jammu and Kashmir.

Collection

Adult fruit flies were collected by using McPhail traps containing cotton pieces treated with 10-12 drops of attractant (Methyl Eugenol and Cue lure) mix with chemical insecticides (Malathion). Also, fruit flies’ specimen was collected from infected plant hosts like Peach, Figg, pear, Persimmon, Apple and Guava in vegetable cucumber, Bitter gourds and Bottle gourds. 6-8 traps were placed in one hectare. These traps were hanged at the height of 2-3 meter with the branches of fruit trees in the experimental area under observation. The trapped specimen’s data like number of species in each trap was recorded on fortnightly bases throughout the year.

Preservation

Collected specimens were brought to laboratory of department of Entomology in glass vials and pinned. After pinning specimens were oven dried 45-50°C and preserved in wooden boxes with necessary information i.e. host, locality, date of collection and collector name on tag.

Identification

The collected specimens were identified under microscope (Leica MZ6) up to species level with the help of available literature (Mahmood and Hassan, 2005) and pictorial keys (Prabhakar, 2012). The specimens were identified on the basis of morphological characters like antenna, wings pattern, strips pattern on thorax, legs types, tergites present on abdomen.

Discussion

Fruit fly is a serious pest causing severe damage to several fruits and vegetables and effect economy and trade of many countries. In Pakistan fruit fly causes losses in vegetables and fruits that range from 20-90% in different part of country. Pakistan is among the major fruits and vegetables producing countries, which are providing important source of nutrition for its local population, but also to other countries of world. Today, with increasing globalization, it has become necessary for the nation not only to feed its own population, but also have to export these produces to other countries of world. There are many challenges for an exporting country to send its perishable items to other populations of the humankind. The main challenge faced by this country is the strict requirement of quality control and restrictive quarantine measures imposed by importing countries. Thus, to export fruits and vegetables produces in abroad, it is imperative to minimize the concerns owing to fruit fly pests. In present study total 09 species of fruit flies (Diptera: Tephritidae) were reported from Poonch division of Azad Jammu and Kashmir. The captured flies mostly contained four species Bactrocera zonata, Bactrocera cucurbitae, Bactrocera dorsalis and Bactrocera tau (Walker). Bactrocera (Bactrocera) nigrofemoralis, Bactrocera correcta, Bactrocera scutellaris, Dacus sphaerodalis and Dacus longicornis were recorded occasionally. The population trend of all these species was changed throughout the year, it could not be compared with the level of infestation by these species during the years. Minimum population of fruit flies was recorded in May and maximum in August. These results are similar with findings of Mahmood and Mishkatullah (2007) which shows maximum population in August from district Chakwal. Hui and Jinghong (2007) also reported the same population trend of fruit flies in Xishuangbanna, Yunnan Province, China. Out of these 09 species 06 were reported as a new record for Azad Jammu and Kashmir and 01 Specie is a new record for Pakistan. Three species Bactrocera dorsalis (Hendel), Bactrocera zonata (Saunders) and Bactrocera (Zeugodacus) cucurbitae (Coquillett) are already reported from Azad Jammu and Kashmir by Mahmood and Hassan (2005).
