Moniezia expansa could be considered as the most important cestode parasites infecting sheep causing monieziasis which constitutes a problem in sheep breeding. The aim of the present study is to investigate on the anatomical cellular and tissue structure and development of the interproglottidal gland and tegument correspondig to the mechanism of its secretion. The detailed structures of the tegument and microtriches could not be seen by light microscoy examination and also the interproglottidal glands appear as interupted non differential cellular chain inbetween worm proglottides or segments.The ultrastructure study done by transmission electron microscopy (TEM) revealed that the glands develop separately from the tegument and compromising an endocrine character. It was observed that the gland consists of subglobular follicles or vesicles, which are embedded in parenchyma and pushing the tegument at the posterior border of the proglottid, formulated crypt-like structures with central hilum or sinus. The gland secretions were diffused to the tegument and parenchyma of the proglottid through cellular channels (protoplasmic channels) upward to the anucleate syncytial layer of tegument ; apical cytoplasm through cytoplasmic channels.

A survey on the occurrence of mosquito in Kuruva Island was made and their vectorial status was analyzed. This study was undertaken for six months from October 2010 to March 2011. Mosquito larvae were collected throughout the island and were later identified in the laboratory using systematic keys. A total of 18 mosquito species belonging to 5 genera, Anopheles, Aedes, Culex, Mansonia and Armigeres were identified. The habitat preference and vectorial capacity of these mosquito species were discussed.

A total of 365 specimens of freshwater turtles belonging of Two Families Viz., Geoemydidae (Crowned river turtle, Hardella thurjii; Brown roofed turtle, Pangshura smithii and Indian roofed turtle; Pangshura tecta) and Family Trionychidae (Indian narrow-headed soft-shell turtle, Chitra indica; Indian soft-shell turtle, Nilssonia gangetica; Indian peacock soft-shell turtle, Nilssonia hurum; and Indian Flap-shell turtle, Lissemys punctata andersonii were identified. Lissemys punctata (30.95%) and Nilssonia gangetica (27.39%) had abundant population status, whereas, Hardella thurjii (1.36%) and Pangshura tecta (3.01%) were rare. Spotted Pond turtle (Geoclemys hamiltonii was not recorded during the present study, as this Species had been reported by various researchers in different areas of Pakistan. The current study investigated the distribution and abundance of freshwater turtle Species inhabiting in different water bodies of Charsadda of Khyber Pakhtunkhwa Province. Capturing of turtles for export is a major threat to these animals. Fishermen also kill them during fishing. Canal closure, de-silting and destruction of Ecological niches are also harmful to these animals. It is concluded that it is necessary to provide effective and immediate legal protection/Coverage to all turtle species under the Khyber Pakhtunkhwa Wildlife (Protection, Preservation and Management) Act, 1975, Pakistan; otherwise turtle species will become extinct.
