“…For the RK-type compounds, RKTA is the most volatile species. However, its field life is not very long because of its susceptibility to humidity, 34 whereby it quickly hydrolyzes to RK. Because of this limitation, the most volatile and stable RK-like compound is CL, which is about 50-fold less volatile than ME.…”

We report on the vapor pressures at ambient temperatures of seven attractants of Bactrocera, Dacus, and Zeugodacus fruit fliesraspberry ketone, cuelure, raspberry ketone trifluoroacetate, methyl eugenol, methyl isoeugenol, dihydroeugenol, and zingeroneby a vapor saturation method. Dry nitrogen was passed over each compound at well-controlled temperatures. Entrained vapor from the compounds was trapped on Tenax GR tubes and analyzed by thermal desorption–gas chromatography–mass spectrometry. The measured attractant amounts on the traps were converted to vapor pressures. Data were subsequently fitted by the Antoine equation. From the Antoine equation parameters, thermodynamic properties for each compound were calculated at 298 K. The calculated vapor pressures were used to compare the volatility of the fruit fly attractants and to infer implications for field applications. Using ambient temperature readings yields far better estimates of vapor pressure values at temperatures relevant for insect control than do Antoine equation parameters derived from high-temperature readings.

“…In particular, they found that (Z)-methyl isoeugenol is the most volatile of the ME-type compounds, while RKTA is the most volatile among the RK-type compounds. Interestingly though, the field life of RKTA is not long due to its susceptibility to humidity [498]. Expanding our understanding of the features of these chemicals as well as of the identity/impact of multiple abiotic factors that may affect their activity is essential to determine the design of the eradication and suppression programs, as well as the location and density of the traps to be used.…”

The Dipteran family Tephritidae (true fruit flies) comprises more than 5000 species classified in 500 genera distributed worldwide. Tephritidae include devastating agricultural pests and highly invasive species whose spread is currently facilitated by globalization, international trade and human mobility. The ability to identify and exploit a wide range of host plants for oviposition, as well as effective and diversified reproductive strategies, are among the key features supporting tephritid biological success. Intraspecific communication involves the exchange of a complex set of sensory cues that are species- and sex-specific. Chemical signals, which are standing out in tephritid communication, comprise long-distance pheromones emitted by one or both sexes, cuticular hydrocarbons with limited volatility deposited on the surrounding substrate or on the insect body regulating medium- to short-distance communication, and host-marking compounds deposited on the fruit after oviposition. In this review, the current knowledge on tephritid chemical communication was analysed with a special emphasis on fruit fly pest species belonging to the Anastrepha, Bactrocera, Ceratitis, and Rhagoletis genera. The multidisciplinary approaches adopted for characterising tephritid semiochemicals, and the real-world applications and challenges for Integrated Pest Management (IPM) and biological control strategies are critically discussed. Future perspectives for targeted research on fruit fly chemical communication are highlighted.
