Summary: This study evaluated the attractiveness of synthetic fruit volatiles in combination with fruit compounds to Drosophila suzukii and found that a simple three-component blend was attractive to D. suzukii, particularly females, but not to non-target Drosophila melanogaster.

Summary: The study evaluated the release rate, duration, and biological efficiency of yeast volatile compounds associated with olive fruit flies in different dispensers. Significant differences were found in the release ratio of 2-phenethyl acetate compared to other volatiles. The attraction of olive fruit flies increased with decreasing concentrations of the tested volatiles. Rubber septa containing 2-phenethyl acetate showed better results in attracting flies compared to other compounds.

Summary: The study found that putrescine could delay the occurrence of anthracnose disease in mango fruit, limit the expansion of spots, and enhance disease resistance by increasing the activities of various enzymes and compounds. In addition, putrescine showed strong antifungal activity against Colletotrichum gloeosporioides and caused severe damage and deformation in the mycelium.

Summary: This article provides an overview of the importance of chemical signals in fruit flies' biology, ecology, and pest control, highlighting the role of various chemical cues in fruit fly behavioral interactions and species-specific recognition. Additionally, key challenges for future research in both basic and applied aspects of tephritids are outlined.

Summary: Female tephritid fruit flies switch their olfactory preferences from male pheromones to fruit stimuli after mating, which may play a crucial role in mating-induced sexual inhibition.

Summary: Thirteen phthalimide derivatives were designed and synthesized in this study. The synthesized compounds were evaluated for their inhibitory activities against female Caribbean fruit flies. Three compounds, 4a, 4c, and 4d, were discovered to have potent insecticidal activity. Compound 4a exhibited the highest inhibitory potency and was found to be less toxic than phthalimide and other precursors. These findings suggest that compound 4a has strong potential as a candidate for developing an environmentally friendly insecticide for pest fruit fly control.

Summary: Wireworms, the larval stage of click beetles, are serious pests of various field crops worldwide. The use of pheromone traps to monitor and manage male click beetles is common, but there is a lack of attractants for females. This study evaluated the attractiveness of different compounds to male and female Agriotes obscurus and A. lineatus, both of which are pests in Europe and North America. The results suggest that attractants for female click beetles may be highly species-specific, highlighting the need for further research and development in this area.

Summary: By using the CRISPR/Cas9 system, a null sNPFR mutant was successfully generated to investigate its physiological roles in the oriental fruit fly. The mutants showed significant differences in foraging behavior and responses to odorants, as well as inhibition of several olfactory receptor genes. The data suggest that sNPFR plays a regulatory role in olfaction-mediated foraging behavior by interacting with specific cells and odorant receptor neurons.

Summary: This study evaluated the oviposition deterrent activity of coconut free fatty acids (CFFA) against the oriental fruit fly (OFF). The results showed that CFFA deterred OFF oviposition in a dose-dependent manner, with four compounds significantly reducing oviposition, two compounds having no effect, and two compounds stimulating oviposition.

Summary: This study found that an isoamyl alcohol-based semisynthetic lure containing red wine as an organic component attracted various fly species, including economically important ones like Drosophilidae and Ulididae, and it is the first reported attractant of the Sciomyzidae family. The phenylacetaldehyde-based synthetic lure attracted fewer families but was efficient against the Empididae and Milichiidae families. These findings provide insights into the chemical ecology of flies and can be used in pest management and ecological studies.

Summary: This study compared the volatile emissions of different life stages of desert locust populations from the field and laboratory, revealing significant chemodiversity between the two populations. The field population nymphs and adults released 4- to 40-fold more volatiles compared to laboratory counterparts, indicating a richer composition. Further investigation into these discriminating odors is warranted to understand their roles in the bioecology and management of desert locust species.

Summary: This study identified two volatile components, benzothiazole and (E)-beta-caryophyllene, that are attractive to Annonaceae fruit weevils. These volatiles, when mixed with the aggregation pheromone, enhance its effectiveness in attracting the insects. The preference of weevils for certain volatiles is influenced by the maturity of soursop fruits.

Summary: This study investigated the effect of infochemicals derived from the habitat, host plant, and host insect on the foraging behavior of the olive fruit fly larval parasitoid. The results showed that the parasitoid strongly preferred volatiles emitted by B. oleae larval-infested fruits and cues emitted by B. oleae females. Volatile analysis revealed qualitative differences in volatile profiles of egg- and larval-infested fruits, indicating that olives change volatile emissions in response to larval infestation. These findings suggest that infochemicals play an important role in the host location behavior of the parasitoid.

Summary: In this study, five series of laboratory tests were conducted to examine different traps and attractants for the capture of Trogoderma granarium and Trogoderma variabile. The results showed that larvae were generally more responsive than adults for both species. Different attractants also had varying effects on the captures of adults and larvae of T. granarium. Furthermore, the type of trap used affected the captures of T. variabile larvae. Therefore, more effective trapping methods can be developed to monitor T. granarium.
