Impact of botanical extracts derived from Melia azedarach and Azadirachta indica on populations of Plutella xylostella and its natural enemies: A field test of laboratory findings

THE EFFECTIVITY OF CITRONELLA AND CLOVE OILS AGAINTS CABBAGE CATERPILLAR Crocidolomia pavonana

“…Botanical pesticide is potential for controlling the major pests of agricultural crops owing to utilizing the plant secondary compounds as the active ingredient. The compounds serve as a repellent, attractant, killer and inhibiting appetite of targeted pests (Charleston et al, 2006). The use of botanical pesticides is expected to reduce the use of chemical pesticides/ synthetic, so that the residues of chemical pesticides carrying a variety of negative effects on the environment can be minimized as low as possible (Wiratno, 2011).…”

Mortality of Oryzophagus oryzae (Costa Lima, 1936) (Coleoptera: Curculionidae) and Spodoptera frugiperda (J E Smith, 1797) (Lepidoptera: Noctuidae) Larvae Exposed to Bacillus thuringiensis and Extracts of Melia azedarach

“…Also, Chinaberry leaves at 5% extract, resulted in > 90% mortality in Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) (Brunherotto and Vendramim 2001). The aqueous extract of M. azedarach together with Neemix 4.5 ® was effective in the control of Plutella xilostella (Linné, 1758) (Lepidoptera: Plutelidae) (Charleston et al 2006). Corrected mortality (ca.…”

“…For example, M. azedarach (Meliaceae), or Chinaberry has insecticidal properties (Huang et al 1996, Ventura andIto, 2000;Brunherotto and Vendramim 2001) due to various compounds, such as salanalin, meliaterin, and meliacarpinin. Some other compounds from this plant have insecticidal activity against beetles (Curculionidae, Tenebrionidae, and Chrysomelidae), as well as Lepidoptera (Huang et al 1996;Bohnenstengel et al 1999;Carpinella et al 2003;Charleston et al 2006;Nathan 2006). The objective of this study was to assess the toxicity using in vivo assays of two new isolates of B. thuringiensis Cry proteins and an aqueous extract of M. azedarach as possible control agents for the rice pests O. oryzae and S. frugiperda.…”

Secondary Metabolism as a Measurement of Efficacy of Botanical Extracts: The Use of Azadirachta indica (Neem) as a Model

“…The potential of natural products as agents to control insect pests is clear in several papers which describe their biological activities (Céspedes et al, 2004(Céspedes et al, , 2005Charleston et al, 2006;Nathan et al, 2006aNathan et al, , 2006bNegahban et al,2006;Rharrabe et al, 2008;Torres et al, 2003). However, in order for the use of natural products to thrive, as an alternative to traditional synthetic pesticides, some parameters of production and quality control should be observed, especially a) seasonal variation; b) formulation and stability and c) development of methods to quality control.…”
