Repelentní účinky silic vybraných rostlinných druhů
 Mašláňová, Hana
Essential oils which plants synthesize for their own protection against phytophagous insects and pathogenic organisms, can also be used in the fight against hematophagous insects and wide range of agricultural pests. The insect is a transmitter of many diseases and in high frequencies causes a decrease in production and economic losses in livestock production. This retrieval thesis is focused on the essential oils with repellent effects and their possible use in the protection of large livestock. The advantage of repellent products based on essential oils is their safety, environmental compatibility, low toxicity to non-target organisms and low risk of resistant insect populations. Among the plants with repellent effects belong also representatives of the genus Pelargonium and family Lamiacea. Especially essential oils from Pelargonium graveolens, P. roseum, P. capitatum and their hybrid varieties and oils of Mentha spp. could be formulated for the use as repellents in livestock protection.
