Citrus is one of the important fruit grown in Punjab, particularly in Sargodha region. Its export plays a vital role in Pakistan‟s economy. However it is adeversely affected by many biotic and abiotic factors. Among biotic factors, a large number of insect pests attack on citrus crop even before flowering to fruit formation which ultimately results in decreased fruit production and poor juice contents. A large number of insecticides are used to control citrus insect pests but their indiscriminate use causes environmental pollution, primary pest outbreak, secondary pest resurgence and development of resistance against insecticides. Therefore, to overcome the ill-effects of insecticides, there is a need to design a widespread integrated pest management strategy. In nature, different natural enemies play a vital role in the reduction of citrus insect pest‟s population. Natural enemies such as predators, parasitoids and pathogens are used for biological control of different insect pests. Several natural enemies attack on various prey or host species while few are host specific such as parasitoids. Most of the parasitoids belong to family Braconidae of order Hymenoptera which contains large number of parasitoid species that successfully control several important plant pests. This family comprises of 44-47 subfamilies and about 1000 genera with over 40,000 species that are widely distributed all over the world. Prevalence of more number of species in district Sargodha provided us basic information about the efficiency of parasitoids as biocontrol agent. In this study, braconids fauna from different localities of Sargodha region were explored, with particular reference to citrus orchards. For this purpose different kinnow orchards in selected localities were selected for the collection of parasitoids and their mummies. The parasitoids were identified under the microscope using taxonomic keys. Confusing species of parasitoids were further identified by their DNA sequences. Diversity index (Simpson) method was used to find the most prevalent species in each tehsil of district Sargodha.

 ماہرؔ القادری
جناب ماہر القادری کی وفات کی خبر سے بہت ہی دل گیر اور دل فگار ہوکر جب یہ تحریر لکھنے بیٹھا ہوں تو کراچی کی ساری علمی و ادبی مجلسیں یاد آرہی ہیں۔
کراچی بارہا جانے کا اتفاق ہوا، وہاں کی ممتاز شخصیتوں کی یادوں کی قندلیں روشن کرتا رہتا ہوں، ان میں بہت سے اﷲ کو پیارے بھی ہوگئے، اختر جونا گڑھی مرحوم یاد آتے ہیں، ان کی کتاب ’’طبقات الامم‘‘ دارالمصنفین سے شائع ہوئی تھی، معارف میں مولانا شبلیؒ پر اچھے مضامین لکھے، وہ بزرگ محترم مولانا سید ابوظفر ندوی مرحوم کے ساتھ جونا گڑھ سے شہاب رسالہ بھی نکالا کرتے تھے، دارالمصنفین کے بڑے قدردان رہے، وہ جس محبت سے کراچی میں ملے اس کی یاد برابر باقی رہے گی، ان ہی کے یہاں کھانے پر حفیظ ہوشیار پوری مرحوم سے ملا تھا، ان کے پرکیف نغمہ شعری سے بھی محظوظ ہوا تھا، ان کی محبت بھری باتوں میں بڑی کیفیت تھی، ممتاز حسن مرحوم (ریٹائرڈ سکریٹری محکمہ فنانس حکومت پاکستان) یاد آتے ہیں تو ان کی علم نوازی، کرم گستری اور دوست پروری کے معطر اور نکہت بیز پھولوں کے بار سے دبتا چلا جاتا ہوں، ایک رات جناب جمیل عالی کے دستر خوان پر میں جناب ممتاز حسن مرحوم، ابن انشاء مرحوم اور یادش بخیر پیر حسام الدین راشدی کے ساتھ شریک ہوا، رات کو ایک بجے تک علمی و ادبی باتیں ہوتی ہیں، وہ رات بھی کیسی حسین اور بہار آفریں تھی، ممتاز حسن مرحوم ایک تناور سایہ دار علمی برگد تھے، اسی کے چھاؤں کے نیچے کراچی کے ارباب علم جمع ہوتے اور ان کے سایہ عاطفت میں اپنے علمی و ادبی ذوق کو پھلتے پھولتے محسوس کرتے، جناب ابن انشاء مجلسوں میں ملتے اور خاموش بنے رہتے، مگر اخبار کے کالم میں شب برات کی پھلجڑی اور...

Studies on Vegetation Structure and Species Diversity of Sathan Gally, District Mansehra

This study was designed for the first phytosociological exploration of the floristic exploration of Sathan Gally, District Mansehra, Pakistan. The study area, part of the Western Himalayas, shows rich floristic diversity. In this investigation, an effort was made to document the phyto diversity and vegetation structure of the area by using quadrat method and standard phytosociological tools.A sum of 35 sampling sites were selected randomly for vegetation analysis and 20 quadrats were laid down for herbs, 10 for shrubs and 5 for trees at each sampling site. The study area was visited frequently during flowering seasons of 2013 and 2014. Plant species were collected from a range of localities, identified, preserved and deposited in the Herbarium of Hazara University, Mansehra. The current investigation was conducted to explore the floristic diversity and vegetation structure in context of environmental gradients of investigated area.A total of 170 plants species, belonging to 154 genera of 73 families were recorded in 35 stands. Angiosperms were represented by 92.85%, Gymnosperms by 2.97% and Pteridophytes by 2.16% species. The leading family was Asteraceae represented by 20 species, followed by Rosaceae by 14 species, Poaceae by 12 species, Lamiaceae by 10, Polygonaceae by 5, Primulaceae by 4 species and Caryophyllaceae and Moraceae by an equal sharing of three species each. TWINSPAN multivariate classification and ordination method by CANOCO software which is being used in most of the phytosociological surveys across the world, was applied. TWINSPAN identified six plant communities viz., Pteris-Urtica-Pinus, Pinus-DigitariaSarcococca, Dryopteris-Cedrus-Pinus, Pinus-Cedrus-Indigofera, Pinus-AbiesViburnum and Themeda-Indigofera-Ailanthus. The phytosociological attributes like density, frequency, cover, importance values index, leaf size spectra, life form, index of diversity, species richness and species maturity were recorded. Microphyll contributing 40.47% species were leading leaf spectra class followed by Mesophyll containing 26.78% species, Nanophyll by 24.4% species, Macrophyll and Leptophyll 4.14% species by each. Therophytes were found as leading life form class of the area contributing 30.35% species, followed by Hemicryptophytes 20.23%, Megaphanerophytes 16.66%, Geophytes and Nanophanerophytes by 12.5%, and Chamaephytes by 7.14% species. The Reserved forest showed rich floristic diversity as compared to Guzara forest. In the current study a total of 127 plants species consisting of 59 common and 68 different were found in 13 stands of reserved forest. Angiosperms were represented by 118 (92.91%), plant species Pteridophytes 5(3.93%) species and Gymnosperms 4 (3.14%) species were recorded in Reserved forest. Only single species of climber was documented. The dominant family was Asteraceae (13 species, 10.7%) followed by Labiateae (10 species, 7.75%), Poaceae and Rosaceae (8 species, 6.2%) each, Polygonaceae and Pteridaceae by (5 species, 3.87%) each. Four different plant communities were recognized by TWINSPAN in Reserved forest. A total of 103 plant species of 55 families including 61 common in both forest types and 42 species different to Reserved Forest. These plant species were documented from 22 sampling stands. Angiosperms by (92.3%) plant species Gymnosperms (2.88%) and Pteridophytes (4.8%) were recorded. The dominant family was Poaceae by 11 plant species followed by Asteraceae and Rosaceae each represented by 10 species and Pteridaceae by five plant species. Three plant communities were recognized in Guzara forest by TWINSPAN. The study revealed that the indigenous peoples of the area exploited86 (51.19%) species as traditional medicinal plants, 136 (80.95%) species for fodder, 48 (28.57%) for fuel wood, 28 (16.66%) for timber woods, 07 (4.16%) forwild vegetable and 02 (1.19%) for ethno-veterinary therapies. Similarly, 17 (10.11%) species for wild edible fruits, 2 (1.19%) species for making agricultural tools, 1 (0.59%) species for fencing field borders. It was observed that the local inhabitants used plant resources for single and multiple purposes. Palatable flora was also documented and it showed that 79.16% of the total recorded flora were grazed by goat, cow, sheep and buffalo in the study area while 20.83% flora was found non-palatable. This study will assist ecologists, botanists, taxonomist, conservationists and policy makers to manage the current statusof plants. The present investigation will also serve as baseline for future researches on the Himalaya Regions.
