The random amplified polymorphic DNA (RAPD) assay was used to assess the level of DNA damage in various exposed and unexposed Culex quinquefasciatus larvae to acetone and chloroform extracts of Curcuma longa and Melia azedarach at different concentrations (6.25, 12.5 and 25 ppm). This is the first report of an analysis of genomic alterations in plant extracts-treated mosquito larvae using RAPD-...

This study was carried out to determine the effects of crude terpenoid compound extracts Melia azedarach L. leaves and fruits on some biological aspects whitefly Bemisia tabaci (Genn.) under laboratory conditions 25 ± 2°C relative humidity 65-70%. The results indicated a significant effect eggs immature stages when treated with 0.5, 1, 1.5, 2 mg/ml fruits. mortality rate increased concentration...

Sawdust as a soilless growth substrate for plants is becoming popular in greenhouse production. However, fresh sawdust often requires time decomposition before it ready use substrate. We studied whether amendments of banana peels (as source potassium), eggshells calcium), and urea nitrogen) non-composted chinaberry (Melia azedarach) could enhance its potential medium. In two pot experiments, th...

ABSTRACT. Biosorption is a cost effective tool for removing heavy metals from aqueous solutions. In the present study, M. azedarach biomass has been used biosorption of Ni(II) ion solution. The effect pH, contact time, concentration and temperature were separately studied. optimum pH was found to be 6.0. 92% founded, when 25 mg/L initial concentrations at room temperatures in 60 min. It also ob...

background:  the extracts of different parts of plants were found very effective against various pests. the aim of this research was to determine the insecticidal activity of fruit methanol extracts obtained from melia azedarach (meliaceae), phoenix theophrasti (arecaceae), styphnolobium japonicum (fabaceae) and pyracantha coccinea (rosaceae) against the larvae of culex pipiens (diptera: culici...

silver nano-particles have different biological applications due to their compatibility. chemical methodsusually result in remaining some amounts of toxic reactions on the nano-particles. for this reason, the useof plants as sustainable and accessible resources in preparation of compatible nano-particles has attracteda lot of attention in the recent years. this research investigated the green s...
