Abstract

Study "Bioefficacy of extracts from Lantana camara L. against Spodoptera exigua" to create products that are effective in treating pests and protecting environment, improving the value of medicinal plants. Qualitative analysis determined the presence of saponins, alkaloids, tannins and phenols compound in the ex tract. The extract of Lantana camara exhibited a good mortality effect, growth inhibitors and rate against Spodoptera exigua at 35% concentration. Anti-feedant activity of L. camara extract was evaluated against diamondback moth by using a leaf-disc choice test and no-choice leaf test. Spodoptera exigua feedding activity was significantly reduced almost 74% and 89,76 when 35% leaf extract concentration was applied. The effect of Lantana camara extract against Spodoptera exigua in the greenhouse condition reached the highest efficiency at 71.57% after 8 days.
