“…Usually larger doses of plant extracts inflict mortality either by inhibiting feeding or reducing digestibility or inhibiting growth. Smaller doses of extracts may not be adequate for killing the insects however; it may sometimes induce malformation [24,35,36]. In several plant species have antifeedent, insecticidal and larvicidal properties, consequently, the chemical pesticides alternative to many plant based pesticides to be produced, which is not pollute our environment.…”

Pests are responsible for global pre and post-harvest crop losses of approximately 20-50% potential production. The Rice leaf folder (Cnaphalocrosis medinalis guenee) is a predominant foliage feeder and one of the most destructive pests affecting in all the paddy field. The use of plant products or plant derived compounds as safe alternatives to Chemical insecticides in controlling insect pest. Totally 16 plants were collected from in and around Thiruvannamalai District. The fresh leaves were washed with tap water and then rinsed distilled water 10 gm of washed plant materials were taken into the morter and add 100ml of distilled water to prepare raw experimental solution. The rice leaf folder (Cnaphalocrosis medinalis guenee) were used in this experiment and collected from a paddy field in Cheyyar. In this study dealing with the anti-feedant effect of extracts was studied by leaf dip assay method. Fresh paddy leaves measuring 15cm length were dipped in the test tube. in each petridish, a total of 5 treated leaves with one leaf folder larva each petridish were taken. As the result of experiment 4 plant leaf extract is very effective in all over 16 plants. Finally, Melia azedarach, Abutilan indicum, Calotropis procera and Calotropis gigantea, showed 80-100% mortality.

“…Enquanto, o reuso é pouco praticado, destacam-se como candidatos comuns ao processo de reciclagem, os seguintes resíduos: a) Solventes b) Combustíveis em geral c) Óleos d) Resíduos ricos em metais, especialmente os preciosos e) Ácidos e bases f) Catalisadores A destilação fracionada é, sem dúvida, o processo mais utilizado no caso de solventes orgânicos, seguida por filtração para resíduos sólidos e extração por solventes para óleos e sólidos (Ahmad, Barton, 1999;Jardim, 2001). …”

“…In this line there are several other contributions. Ahmad and Barton2 solved the sequencing problem of reactors and distillation columns to minimize the amount of waste produced by the process. Based on their method to find “batch” distillation regions, they determined the best composition and amount of solvents fed to the reactors and the best recycling policy for the column products.…”
