A total of 26 banana orchards, showing typical symptoms of banana wilt as well healthy ones were surveyed. The roots and soil samples from the banana rhizosphere were collected for the isolation and identification of suspected pathogen, Fusariumoxysporumcubense and the burrowing nematode (Rhadopholussimilis) that are causing the Panama wilt in banana plantations. 2018-07-20T00:00:00Z http://localhost:80/xmlui/handle/123456789/17841 Title: Effect of Mermis spp. infection on the fecundity of insect pests of grasshoppers Authors: S.Riffat; S.Kumar; A.Soomro Abstract: Grasshoppers are subjected to attack by a wide range of predators and parasites at all stages of their life cycle. Fecundity of these predators and parasites of the insects was affected when grasshoppers were contaminated with Mermis spp. Mostly, the females laid fewer eggs than normal. The numbers of eggs produced were 17.5±3.0, 11.2±5.3 and 8.6±4.3 for Poekilocerus pictus, Oxya velox and O. hylahyla, respectively, for infested insects, whereas, it was 43.3±5.2, 37.8±6.30 and 39.34±5.2 in uninfected grasshoppers. Beside this, it was also noticed that insect infected with Mermis spp. did not survive for long. Dissection examination showed that there was significant suppression of oocytes and testis development in infected individuals. 2018-07-20T00:00:00Z http://localhost:80/xmlui/handle/123456789/17840 Title: Ascaridia galli infection induced gross-pathological changes in broiler chicken Authors: S.Feroza; A.G.Arijo; F.M.Bilques; S.Phulan Abstract: In this study, the effect of Ascaridiagalli infection on gross-pathological changes in broiler chicken was investigated. The postmortem examinations of broiler experimentally induced A.gallirevealed gross pathological lesions of infected organs viz., small intestine, liver, lungs and heart. Hemorrhagic enteritis and acute fibrinous enteritis with clotted blood, hemorrhagic and reddish spots on intestinal wall, inflammation and necrotic patches with consolidation of intestinal contents were generally observed. Infected liver showed dark red coloration. Severe congestion, chronic pneumonia, exuded in one lobe of the lung were seen, whereas, necrosis and atrophy in infected heart were notable observations. 2018-07-20T00:00:00Z http://localhost:80/xmlui/handle/123456789/17839 Title: Impact of nematode infestation on nutritional quality of some underground vegetables in Pakistan Authors: M.Israr; F.Shahina; M.Habib Abstract: During the present investigation the nutritional quality of underground vegetables infected by root-knot nematode (Meloidogyne incognita) was evaluated. It was observed that physiological and biochemical changes occurred due to the invasion of root-knot nematodes in the studied vegetables. Results show that there was a significant difference in root-knot development and reproduction in infected and un-infected host plants. Data indicates that highest reproduction rate and root-knot index was observed in vegetable plants infected with root-knot nematodes after three months as compared to un-infected (control). The physiological parameters as well as biochemical contents showed significant difference in different growth criteria and amount of nutrients between infected host plants as compared to un-infected plants (control). Growth parameters of studied vegetable plants viz., fresh and dry weight and water content were decreased by the infection of root-knot nematode as compared to un-infected (control) plants. Similarly root-knot nematode decreased the host nutrients contents viz., total carbohydrates, total soluble sugars, total protein, total phenols and amino acids. Chlorophyll a, chlorophyll b and carotenoids also decreased in nematode infected plants as compared to control. This study gave the fair report towards nutritional quality because no significant work has been done so far on this aspect in Pakistan. 2018-07-20T00:00:00Z
