In the present study, alternative control possibilities were investigated against mushroom scatopsid flies, Scatopse spp. (Diptera: Scatopsidae), which have recently been an important cause of pest problems in mushroom growing cellars in the Antalya-Korkuteli district, an important place in the mushroom production of Turkey. For this purpose, the essential oils extracted from pennyroyal (Mentha pulegium L.), sage (Salvia tomentosa Miller), wild thyme (Thymbra spicata L. var. spicata) and savory (Satureja thymbra L.) and their main components (pulegone, beta-pinene, carvacrol and thymol, respectively) were tested for their fumigant activity against the adults of mushroom scatopsid flies. Various concentrations (0.5, 1, 5 and 10 mu l/l air) and exposure periods (0.5, 1, 2 and 4 h) were used to determine the fumigant activity of the test materials. According to the results from the study, all the essential oils and their components showed a fumigant toxicity in varying degrees, M.. pulegium essential oil and its major component, pulegone, being the most active (after 0.5 h, LC50 = 0.17 and 0.13 mu l/l air, respectively). After a 4-h exposure period, both the oil and the component produced 100% mortality at all the concentrations tested. Even after a shorter exposure period (2 h), they achieved the same mortality at level as all the concentrations, except for the lowest dose (0.5 mu l air). All the responses were found test material- exposure period- and concentration-dependent. Our overall results suggest that the essential oils and their major components tested may be potential alternatives (as fumigants) to synthetic insecticides for the control of mushroom scatopsid flies.
