Dragonflies are predators, they themselves are subject to predation by frogs, spiders, fish, water bugs, birds, lizards, and even other large dragonflies. Dragonflies have great agricultural importance because they are voracious predators of those insects which are pest of many field crops. In the present studies about 600 specimens of the order Odonata were collected from the various localities, include sixteen species belonging to eleven genera, representing three families, two subfamilies of the suborder Anisoptera, and were described in detail with special reference to their male and female genitalia from Sindh, Pakistan. The research techniques and information are helpful for graduate and research students of Zoology, Entomology, and Agricultural Sciences.

Animals are very important part of our biodiversity. They are the living part of our colorful nature and have always fascinated human imaginations and figure abundantly in literature and art and craft. Pakistan has 188 species of mammals, 670 species of birds, 185 species of reptiles, and 22 species of amphibians. In this study, biology and behavior of Nilgai, Chinkara, Hog Deer, Blackbuck and Chital was studied at the Safari Park and Karachi Zoo. It was observed that captive animals develop different kind of behaviour depending upon the environment provided. Safari Parks and Zoos have a capability to become centers for animal behavior. The research techniques and information are helpful for graduate and research students of wildlife, National Parks managers, wildlife biologists, wildlife conservation organizations etc.

Pakistan annually produces about 25 million tons of wheat & 6 million tons of rice. Storage of these grain is undertaken for various domestic and commercial reasons. During storage heavy quantitative and qualitative losses are known to occur that reduce the food availability and render monitory losses. Major shortcomings in this regard are poor sanitary conditions, leaky and poorly maintained warehouses and ill trained storage officials. Storage losses are not only a problem in wheat and rice but also effect the other stored grains. During storage, insect pests are known to cause considerable damage and weight loss to these commodities. In this study seven (7) methods of loss assessment were examined to investigate the actual losses in stored IRRI-6 and Basmati varieties of rice and wheat stored in public sector godowns. Studies have concluded that during one year storage 1-2% average loss on dry basis was recorded depending upon various factors. Study also pin pointed the areas of future research.

The suborder Ischnocera (Phthiraptera) comprises two families, family Philopteridae Burmeister and family Trichodectidae Kellogg. They have highly diversified forms of body, chaetotaxy and sizes. The members of Trichdectidae are exclusively mammalian parasites, whereas philopterids are truly avian parasites with high level of host specificity. In the Karachi Region, Philopterid genera have been surveyed out in the present work. The representatives of genera Anaticola, Brueelia, Campanulotes, Chelopistes, Columbicola, Cuclotogaster, Goniocotes, Goniodes, Lipeurus, Neopsittaconirmus and Sturnidoecus are included and described here with special emphasis is given to the structure and arrangement of setae and genitalia of male and female where available. The results are compared with findings reported in the existing literature. All the taxa are compared with their closest allies, and keys to the genera and species are formulated on the basis of reliable characters, which help readily identify the taxa.

A detailed morphological study of two new species of Phthiraptera have been described. One belongs to the genus Heleonomus (Amblycera: Menoponidae), from common cranes, Grus grus (Gruiformes: Gruidae) and the other new species of the genus Chelopistes (Ischnocera: Philopteridae) from common turkey, Meleagris gallopavo (Galliformes: Phasianidae) were recorded from Pakistan. These chewing lice species have been taxonomically enlightened and illustrated with respect to the chaetotaxy and male and female genitalia features. It is a new record of the genus Heleonomus in Pakistan. Both the species have also been compared with their closest allies.

Pakistan Produces about 24 million tons of wheat annually. Out of this 6-7 million tons are procured by the Government and stored in its warehouses located throughout the country. The larger quantities are stored by the farming community for their food, feed and seed requirements. The storage of food grain is not well established in the country and the farmers, traders and the Government largely rely on traditional warehousing and practices. The use of silos at public sector and farm level is only negligible. All most all the grain is stored in bags with the exception of few bulk storage traditional farm level facilities. This results in massive quantitative and qualitative losses to the country. The major short-coming in this regard are poor sanitary condition, leaky and poorly maintained godowns and ill trained storage officials. The purpose of the present study is to assess the fumigability of the different types of godowns used for storage of wheat and draw guidelines for pest control. The study also includes understanding of the public sector grain storage problems, covering all important types of storage structures used in the country

Members of the family Elateridae commonly known as Click-Beetles and their larvae called Wire Worm. They are widely distributed all over the World, They are taxonomically difficult group and having ecological and economical importance. Adults are usually nocturnal hiding during day time under stones, in leaf litter, or under the bark and attracted to light. Several species are diurnal and can be found upon flowers. Body elongate, antennae long, usually11- segmented, labrum exposed, hind pronotal angles well developed, procoxal cavity open both internally and externally, posterior margin of prosternum elongated to form prosternal spine form the characteristic Jump-Click mechanism. Jumping mechanism without legs support is a unique character of adult elaterid. Most of larvae are predators; they are elongate, cylindrical to flattened body. In the present work, a contribution towards the knowledge about Elateridae of Pakistan, mainly agrypnids (Agrypninae: Agrypnini, Conoderini, Hemirhipini) have been studied.
