“…Various climatic parameters influence the attraction of olive fruit fly by YST-containing volatile compounds as attractants in two ways: first, by the evaporation of volatiles from dispensers and, second, by the population and development of B. oleae . Of all climatic parameters, temperature and humidity are the most important for the development of most insect species, including the olive fruit fly [ 17 , 28 , 29 ]. On the other hand, the evaporation of volatiles from dispensers depends not only on climatic conditions, such as temperature, humidity, air pressure, and wind speed, but also on the chemical nature of the compound and the type of dispenser from which it evaporates.…”

“…A temperature range was set to simulate the average daytime (23 ± 1 °C) and nighttime (17 ± 1 °C) temperatures throughout the experiment. At the same time, the influence of the actual climatic parameters on the release ratio of all studied volatile compounds in the olive grove was tested using the weather data from the nearest weather station [ 29 ] (see Table 6 ).…”

The objective of this study was to evaluate the release rate, duration, and biological efficiency of yeast volatile compounds associated with olive fruit flies in slow-release dispensers, polypropylene vials, and rubber septa attached to yellow sticky traps under different environmental conditions in order to protect the environment, humans, and nontarget organisms. Isoamyl alcohol, 2-octanone, and 2-phenethyl acetate were placed in dispensers and tested over a four-week experiment. The weight loss of the volatile compounds in both dispensers was measured, and a rapid, inexpensive, and simple HS-GC/FID method was developed to determine the residual amount of volatiles in the septa. 2-Phenethyl acetate stood out in the rubber septa and showed a statistically significant difference in the release ratio compared to the other volatiles under all conditions tested. Our results showed that the attraction of olive fruit flies increased with decreasing concentrations of the tested volatiles. Regarding the number of flies attracted by rubber septa containing 2-phenethyl acetate, significantly better results were obtained than for septa containing isoamyl alcohol and 2-octanone, in contrast to the attraction of olive fruit flies to polypropylene vials containing these compounds but without significant difference. Since the presence of all tested chemicals was detected during the experiment, this opens the possibility of using more environmentally friendly and cost-effective dispensers with a significantly lower amount of semiochemicals.
