BIOPRODUCTION OF AN EXTRACT FROM PENICILLIUM-FUNICULOSUM THOM WITH ACTIVITY AGAINST CERATITIS-CAPITATA AND TETRANYCHUS-URTICAE

The bioproduction conditions of a crude extract from a strain of Penic illium funiculosum Thom, which shows activity against Ceratitis capita ta and Tetranychus urticae, have been optimized. The efficacy degree w as 95% (C. capitata) and 100% (T. urticae), according to Abbot. This i s the first report on the pesticide activity of an extract from P. fun iculosum against these species. The best yields were obtained when P. funiculosum was grown in Raulin-Thom medium at pH 6.5 with sucrose can dy as the carbon source and ammonium sulphate and phosphate as the nit rogen source. Other favourable conditions were static cultures, at 28- degree-C, and in the dark.
