The aim of this study was to evaluate the repellent efficacy for mosquitoes (Anophelex spp) of three doses of neem oil (Azadirachta indica A. Juss) in pigs under field conditions. The research was carried out at a time of year of abundance of mosquitoes in Tumbes, Peru. Forty recently weaned piglets were used, 10 per treatment, kept in indoor cages protected against mosquitoes. For the field test, four piglets per day were exposed randomly in external cages without protection to the mosquito (a different animal for each treatment per day) for 14 days over a period of two months. Neem oil was extracted with the soxhlet apparatus and the formula included 30% glycerin, 1, 2 or 3% neem oil (T1, T2, T3, respectively), and taken to 100% with pharmaceutical alcohol. A dose of 50 ml/piglet distributed throughout the body was applied. The bites and the number of mosquitoes were evaluated on four ...

Tumbes es una zona que por sus condiciones agroecológicas es propicia para la proliferación de zancudos, los cuales inciden negativamente en la salud y proceso productivo de los cerdos. Por ello se gasta en repelentes químicos costosos y perjudiciales para animales, por lo que resulta ser una buena alternativa la utilización de productos botánicos que proporcionen este efecto, como es el caso del neem (Azadirachta indica), planta con característica repelente que puede ser utilizada para cerdos. El objetivo principal del presente trabajo fue evaluar el efecto repelente en el cerdo contra zancudos, del aceite del neem (Azadirachta indica A.Juss.)obtenidomediante el método soxhlet, utilizando tres concentraciones de extracto de neem al 1, 2 y 3%, aplicado en lechones por trece días, para determinar el porcentaje de repelencia, porcentaje de protección, índice de repelencia, porcen...
