| Abstract: The aim of this study was to evaluate the production performance of Nile tilapia post-larvae and fingerlings fed with increasing levels of alcoholic extract of propolis into diets. In Experiment 1, 1800 post-larvae were distributed in 30 tanks, in a completely randomized design with five treatments composed by the inclusion of 0, 1, 2, 3 and 4 g of dry propolis/kg of feed, and six replicates. In experiment 2, 1600 fingerlings were distributed in the same system and designed as experiment 1. No significant effect was observed between treatments, for final weight, total and standard length, survival, and intestinal villus height. However, the propolis extract inclusion of 1 g/kg in Nile tilapia post-larvae and fingerlings’ feed resulted in a better... |

| The chemical composition of Lippia sidoides essential oils obtained by hydrodistillation was characterized and quantified by GC/MS and their insecticidal activity by fumigation test was assayed against Tenebrio molitor. Moreover, the toxicity of monoterpenes carvacrol, 1,8-cineol and thymol were also evaluated when applied alone or in binary (1:1) or tertiary (1:1:1) mixture. The essential oil of L. sidoides has as major constituents carvacrol (31.68%), ρ-cymene (19.58%), 1,8-cineole (9.26%) and ϒ-terpinene (9.21%), from a 21 compounds identified, being 92.53% of total. Both compounds have insecticidal activity against T. molitor, being the degree of toxicity of carvacrol > 1,8-cineole > L. sidoides essential oil > thymol, and its respectively... |
