چکیده

The study was undertaken to contribute the sustainable management of Spodoptera frugiperda Smith on maize. It aims evaluate insecticidal efficacy Jatropha curcas L. oil S. larvae. Two concentrations J. (10 and 20ml.l-1) were tested by ingestion six larval stages grouped into (L1-2 (3-5 days age); L3-4 (6-8 L5-6 (>10 age)). determined in laboratory phytosanitary protection tests maize carried out field. In laboratory, concentration 10 ml.l-1 with/without emulsifier caused a mortality rate (87-92%) at stage L1-2, (51-58%) L3-4, (57- 68%) after 72 hours ingestion. Concentration 20 over 70% whether applied with or without an all stages. Adult emergence nil for L1-2 <10% other Plots subjected jatropha treatments (2l.ha-1 4l.ha-1 emulsifier) less infested like plots treated Emamectine benzoate (Emacot) compared control untreated. present results indicated that has potential against frugiperda.

Insecticidal activity of synthetic amides on Spodoptera frugiperda.

The phytochemistry of the genus Piper (Piperaceae) has been widely studied due to the biological properties of amides from these plants. In this work, we have synthesized and evaluated the toxic effect of 11 amides against the fall armyworm Spodoptera frugiperda larvae. The naturally occurring piperine was also evaluated. The most active amide was N-[3-(3',4'-methylenedioxyphenyl)-2-(E)-propeno...
