In the present study we tested the toxicity of the aqueous extract of three plants of Solanaceae ( Solanum nigrum, Nicotiana glauca and Atropa balladona ) with regard to the adults of Blattella germanica, where we marked a high mortality rate which can reaching 90% of the population after 30 days of exposure to a dose of 1000 μg / ml of the Solanum nigrum extract, the results give a toxic effect on cockroaches determined at different lethal and sublethal times (TL50% and TL 90 %).
