The tobacco cutworm, Spodoptera litura (Lepidoptera: Noctuidae) (Fabricius), is a polyphagous pest which has developed physiological resistance against a number of known insecticides. In order to reduce the load of synthetic insecticides, ecofriendly alternative strategies are needed. The present studies were conducted to evaluate the insecticidal potential(More)
The systems and software development industry is characterized by a paradigm of project failure. One of the known contributing causes of these project failures is poor requirements engineering and management, which has been repeatedly and widely discussed and documented. But there are other factors also like poor project management practices, poor design(More)
Fungal endophytes play a significant role in plant resistance to insects by altering the nutritional quality of plants or by production of various alkaloid-based defensive compounds. Ethyl acetate extract of endophytic Alternaria alternata isolated from Azadirachta indica A. Juss was tested for its bioactivity against Spodoptera litura (Fab.). Effect of(More)
In agriculture, biocontrol agents have been emerged as safe alternative to chemical pesticides where Streptomyces spp. and their metabolites constitute a great potential for their exploration as potent agents for controlling various fungal phytopathogens. The present study reports an antifungal compound purified from Streptomyces hydrogenans strain DH16, a(More)
Fungal endosymbionts in plants may influence interactions among plants, herbivores and their parasitoids through the production of secondary metabolites. We used a lepidopteran pest and its generalist parasitoid to test the effect of endophyte-infected plants on a third trophic level. Endophytic fungi, Aspergillus flavus and Aspergillus niger, isolated from(More)
Nonfermenting gram negative bacilli (NFGNB) cause serious infections in immuncompromised and hospitalized patients. They cause fatal lower respiratory tract infections in patients admitted to ICU's. The appearance of metallo ß-lactamases (MBL) genes and their spread among bacterial pathogens is a matter of concern. The present study was undertaken to know(More)
Fungal endophytes that live inside plant tissues without causing any apparent symptoms in the host are known to confer resistance to insect herbivores. In the present study, endophytic fungus Aspergillus niger isolated from Acacia arabica was evaluated for its insecticidal potential against Spodoptera litura (Fab.). Ethyl acetate extract of the fungus(More)
Component Based Software Development is important area in software development. In this paper, we describe various algorithms and techniques for efficiently retrieval of components from the component repository. We discuss XNOR similarity function, clustering algorithms like k-mean, K-medoid, K-mode and supervised leaning algorithm like support vector(More)
Salmonella typhi is a true pathogen, which is capable of causing both intestinal and extraintestinal infections. Unusual presentations of Salmonella should always be kept in mind as this organism can cause disease in almost any organ of the body. S. typhi has been reported to cause the life-threatening infections such as meningitis, endocarditis,(More)
