Research ArticleOpen accessEvery word in the titleEffects of Selected Low-Risk Insecticides and Rainfall Rate on Bemisia tabaci Population and Pepper Yellow Leaf Curl Indonesia Virus Incidence on ChiliAndi Nasruddin, Iftitah Kartika Amaliah, Nurul Arfiani et al.Pepper Yellow Leaf Curl Indonesia Virus (PepYLCIV) is a damaging chili disease in Indonesia. Chili growers depend on synthetic insecticides to control the disease by suppressing its vector population, Bemisia tabaci Genn. This study assessed the efficacy of several low-risk insecticides in suppressing the B. tabaci population and PepYLCIV incidence during the dry and rainy seasons. Treatments consisted of different … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 26 Jan 2024 · 5,828 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleChitinolytic Bacteria Isolated from Chili Rhizosphere: Chitinase Characterization and Its Application as Biocontrol for Whitefly (Bemisia tabaci Genn.)Nisa Rachmania Mubarik, Irni Mahagiani, Amaryllis Anindyaputri et al.Problem statement: Chitin, a common constituent of insect exoskeleton, could be hydrolyzed by chitinase. The research was conducted to screen chitinolytic rhizobacteria isolated from rhizosphere of chilli pepper and to determine their chitinase activity in degrading chitin of whitefly, Bemisia tabaci Genn.

The polyphagous nature of the pest makes it as a highly complex species. Approach: The influence of host plants utilized by the species on the population differences at molecular level … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,215 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleCharacterization of Mi1.2 Whitefly (Bemisia tabaci) Resistance GeneSherin Amin Mahfouze, Shipra Saxena, Heba Amin Mahfouze, Manchikatla Venkat RajamTomato (Solanum peruvianum) Mi gene provides resistance to whitefly (Bemisia tabaci), potato aphids and nematode making Mi a useful source in integrated pest management program. The aim of this work was to isolate, clone and sequence Mi1.2 gene from S. peruvianum. In addition, physico-chemical identification of amino acids deduced from Mi1.2 gene was done. Secondary (2D) and tertiary (3D) structures … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 15 Nov 2017 · 7,799 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleGenetic Characterization of a Bovine Breed (Tabapua) Under Artificial Selection Located in the Amazon RegionJose Elivalto Guimaraes Campelo, Marcone Helmer da Silva, Ednaldo da Silva Filho et al.Brazil currently has the biggest commercial bovine cattle population in the world. Several different breeds that come from Europe and India compose it. They are primarily used for dairy and meat production. In Brazil, several high quality genetic background cattle are kept in a condition known as pure breed, meaning no other animal of different genetic background is interbreeding with … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 30 Jan 2013 · 7,558 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleConcentration and Physicochemical Properties of Chitosan Derivatives Determine the Induction of Defense Responses in Roots and Leaves of Tobacco (Nicotiana tabacum) PlantsAlejandro B. Falcón-Rodríguez, Juan C. Cabrera, Eduardo Ortega, Miguel Ángel Martínez-TéllezProblem statement: The chitosan derivatives promote diverse defensive responses in plants, which are affected by chitosan chemical features and concentration. Glucanase (EC 3.2.1.6), Phenylalanine Ammonia-Lyase (PAL, EC 4.3.1.5) and peroxidase (POD, EC 1.11.1.6) are key enzymes in tobacco defense responses. Thus, the aim of this study was to know the behavior of their enzymatic activity in leaves and roots of … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,270 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEvaluation of the Activity of Plant Extracts in Boer GoatsM. Worku, R. Franco, J. H. MillerProblem statement: The effect of extracts from Neem (Azadirachta indica), Wormwood (Artemisia absinthium) and Tobacco (Nicotiana tabacum) with added copper sulfate, on female Boer goats infected with gastrointestinal parasites (GIN) was evaluated. Approach: Following initial screening for infection, animals were artificially infected with a mix containing approximately 80% Haemonchus contortus and 20% Trichostrongylus spp. After 21 days, fecal samples were … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 21 Dec 2009 · 8,477 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsMolecular Characterization of Tospovirus Transmitting Thrips Populations from IndiaRang Lal Meena, T. Ramasubramanian, S. Venkatesan, S. MohankumarThe presence of Tospovirus in thrips vector, Scirtothrips dorsalis has been detected for the first time in India using RT- PCR analysis. Similarly RT-PCR analysis with GBNV infected tomato leaves also resulted in the amplification of cDNA corresponding to the N gene (approximately 830 bp) of Coimbatore isolate.
