Isolation And Identification Of Lactic Acid Bacteria With Antifungal Activity Against Anthracnose Disease, Asma Saleh Elmabrok
Isolation And Identification Of Lactic Acid Bacteria With Antifungal Activity Against Anthracnose Disease, Asma Saleh Elmabrok
Asma Saleh Elmabrok
Abstract: The objective of this study was isolation, identification of lactic acid bacteria from different source and testing their antifungal activity against phytopathogens fungi C. capsici and C. gloe osporio ides. The isolates were identified by their phenotypic and genotypic characteristics and their antifungal activity was performed by the overlay method. Seven LAB isolates were showed good antifungal activity against phytopathogens fungi and were grew at different temperatures, pH and NaCl. However, C5 and G7 have the ability to inhibit the growth of both target phytopathogens fungi compared to other isolates. C5 and G7 identified by API 50CHL kit as …

Descriptions Of Two New Species Of Simulium (Simulium) (Diptera: Simuliidae) From Tioman Island, Peninsular Malaysia, Mohd Sofian Bin Azirun
Descriptions Of Two New Species Of Simulium (Simulium) (Diptera: Simuliidae) From Tioman Island, Peninsular Malaysia, Mohd Sofian Bin Azirun
Mohd Sofian Bin Azirun
Two new species of black flies, Simulium (Simulium) jasmoni and S. (S.) tiomanense, are described on the basis of adult, pupal and larval specimens collected from Tioman Island, Pahang, Malaysia, and are placed in the tuberosum species-group in the subgenus Simulium (Simulium) Latreille. Simulium (S.) jasmoni, new species, is characterised by the female tarsal claw with a minute subbasal projection, an unusual characteristic within the species-group, and S. (S.) tiomanense, new species, is striking in having a dichoptic male head, a characteristic rarely recorded in the family Simuliidae, as well as the pupal thoracic integument with a pit-like organ near …
Relationships Of Black-Fly Species Of The Simulium Tuberosum Species-Group (Diptera: Simuliidae) In Peninsular Malaysia, With Keys To Ten Malaysian Species, Mohd Sofian Bin Azirun
Relationships Of Black-Fly Species Of The Simulium Tuberosum Species-Group (Diptera: Simuliidae) In Peninsular Malaysia, With Keys To Ten Malaysian Species, Mohd Sofian Bin Azirun
Mohd Sofian Bin Azirun
Two species of black flies, Simulium (Simulium) jasmoni Takaoka, Sofian-Azirun & Belabut, 2012 and S. (S.) tiomanense Takaoka, Sofian-Azirun & Belabut, 2012, described from Tioman Island, Pahang, Malaysia, are placed in two different lineages of the tuberosum species-group in the subgenus Simulium (Simulium) Latreille, and have close similarities to S. (S.) tani Takaoka & Davies, 1995 and S. (S.) brevipar Takaoka & Davies, 1995, respectively, which were the only members of the same species-group in the nearest mainland of Peninsular Malaysia. It is suggested that S. (S.) jasmoni and S. (S.) tani in one lineage, as well as S. (S.) …
An Evaluation Of The Nutritional Quality Evaluation Of Three Cultivars Of Syzygium Samarangense Under Malaysian Conditions, Amru Bin Nasrulhaq Boyce
An Evaluation Of The Nutritional Quality Evaluation Of Three Cultivars Of Syzygium Samarangense Under Malaysian Conditions, Amru Bin Nasrulhaq Boyce
Amru Bin Nasrulhaq Boyce
A study was carried out to selected physiological and biochemical characteristics of Syzygium samarangense for their physiological and biochemical characteristics at Functional Food Laboratory, University of Malaya, Kuala Lumpur. Various physiological and biochemical parameters were monitored during two seasons of fruit growth between October, 2009 to August, 2010 with the 'Giant green', 'Masam manis pink' and 'Jambu madu red' cultivars of S. samarangense. Ripened fruits of the different cultivars were collected from the experimental field of Banting, Selangor and analyzed for selected physiological parameters namely chlorophyll fluorescence, quantum yield, fruit weight, total yield, number of seed per fruit, seed weight …
Susceptibility Of Field-Collected Aedes Aegypti (L.) (Diptera: Culicidae) To Bacillus Thuringiensis Israelensis And Temephos, Mohd Sofian Bin Azirun
Susceptibility Of Field-Collected Aedes Aegypti (L.) (Diptera: Culicidae) To Bacillus Thuringiensis Israelensis And Temephos, Mohd Sofian Bin Azirun
Mohd Sofian Bin Azirun
The susceptibility status of field-collected Aedes aegypti (L.) from a dengue endemic area to Bacillus thuringiensis israelensis (Bti) and temephos was determined. Since August 2007, biweekly ovitrap surveillance (OS) was conducted for 12 mo in 2 sites, A & B, in Shah Alam, Selangor. Site A was treated with a Bti formulation, VectoBac® WG at 500 g/ha, from December 2007 - June 2008 while Site B was subjected to routine dengue vector control activities conducted by the local municipality. Aedes aegypti larvae collected from OS in both sites were bred until F3 and evaluated for their susceptibility. The larvae were …
Vertical Dispersal Of Aedes (Stegomyia) Spp. In High-Rise Apartments In Putrajaya, Malaysia, Mohd Sofian Bin Azirun
Vertical Dispersal Of Aedes (Stegomyia) Spp. In High-Rise Apartments In Putrajaya, Malaysia, Mohd Sofian Bin Azirun
Mohd Sofian Bin Azirun
A preliminary study on the vertical dispersal of Aedes populations in high-rise apartments was carried out in Presint 9, Putrajaya, Malaysia. Ovitraps were placed indoors within four blocks of high-rise apartments from the ground floors (0.0 - 3.0 m) until up to the tenth floors (28.1 - 30.0 m). Aedes aegypti was the dominant species found in the ovitraps (87.85%), while Aedes albopictus was found in lower numbers. From total number of larvae collected (650), 40.92% of these larvae were obtained from the fourth block; Block D. The peak density of Aedes sp. was observed at level 6 (16.1 - …
Predation On Pupa Of Chrysomya Rufifacies (Marquart) (Diptera: Calliphoridae) By Parasitoid, Exoristobia Philippinensis Ashmead (Hymenoptera: Encyrtidae) And Ophyra Spinigera Larva (Diptera: Muscidae), Chen Chee Dhang
Chen Chee Dhang
A forensic entomological study was conducted using monkey carcasses (Macaca fascicularis Raffles) that were placed in either an outdoor or indoor environment at a coastal area in Tanjung Sepat, Selangor, Malaysia during May until August 2008. We collected pupae of Chrysomya rufifacies (Marquart) from the carcasses and kept them individually. The emergence of 13 parasitic microhymenopteran, from one of the pupae occurring within a week were identified as Exoristobia philippinensis Ashmead (Hymenoptera: Encyrtidae). Another observation was made whereby a pupa of C. rufifacies was predated by a muscid larva, Ophyra spinigera (Stein). The larva squeezed into the pupa and consumed …
