The raw data correspond to a test carried out with extracts from the combination of Chinabeery tree (Melia azedarach) parts and several solvents with different polarity to control the horn fly (Haematobia irritans). This fly is a hematophagous parasite of cattle, usually increase the production costs, and it is currently controlled by pyrethroids and organophosphates. By this, the study is mainly to expposure fly to differents extract concentratiosn at different times, to probe the insecticidal effectiveness of the natural extracts. We also chemical charaterize the extracts through Gas-Chromatography-Mass Spectroscopy.
