GC-MS method for determination of Drosophila suzukii pheromone’s profile
Belenioti Maria and Chaniotakis Nikolaos
University of Crete, Greece
Drosophila suzukii, (Matsumura), the fruit fly Spotted Wing Drosophila (SWD), is one of the most important polyphagous
pest of many small fruits, specifically stone fruits, berries and grapes. Ovipositor of the female can cause physical damage
to the host fruit upon insertion, rending it soft and thus of no commercial value. Drosophila suzukii has already been recorded
in America and Europe, causing significant economic damages. Nowadays, biological control methods play a crucial role in
the control of insect pests with the ability to suppress pest population below economic thresholds rather than only providing a
temporary control as chemical control does.The new techniques have been focused on semiochemicals, the organic compounds
that transmit chemical signals. Insect pheromones are chemical messages produced and used by insects for communication.
Isolated pheromones are presently used for surveying insect populations and in a number of cases as part of insect control
programs. In order to study the Drosophila suzukii pheromone profile, pheromones were extracted from the fly cuticle. These
extracts were analyzed on a gas chromatograph coupled with a mass spectrometer. Compounds were identified based on their
mass spectrum, retention time and internal standard. The comparison of the CH profile of male and female showed only
quantitative differences. Finally, some newly compounds were detected.
