Several Trichoderma species are used as biocontrol agents due to their high potentiality to produce a wide array of bioactive secondary metabolites; (some of these metabolites are low molecular weight volatiles). Trichoderma asperellum was isolated from the rhizosphere of Zea mays at Ismailia, which showed high antifungal and nematoicidal activity from our preliminary experiments. Bioactivity of T. asperellum against mite Tetranychus urticae koch was tested. Data showed that high mortality was observed after exposure time (48 hrs.) and reached 100%. The major volatile compound emitted from T. asperellum was identified to be 6-pentyl- α-pyrone (6PP), with rate 450 ng/µl. This high level of 6PP motivated us to apply different concentrations of pure compound (0.125, 0.25, 0.50 and 1mM of 6PP (sigma) to find out their effect
