Usage of agricultural DAPfertilizer and <em>Eucalyptus</em> essential oils as potential attractants against the Mediterranean fruit fly <em>Ceratitis capitata</em> (Tephritidae)

Abstract

This work aims to develop and evaluate an attractant based on the combination of DAP and Eucalyptus essential oils. Essential oils were isolated by steam distillation from Eucalyptus species and analyzed by GC-MS. About 12 and 22 constituents were identified with 1.8 was the major compounds in crude essential oil and formulations. The adsorption efficacy depends on the abundance of each compound in crude essential oils and the polarity of terpenic components. Results indicated the attractant potential of both essential oils (class III) and that DAP/essential oils formulations accomplished better attractant performance (class IV). Formulations were toxic against medfly adults.
