“…The trap crops act as sacrificial plants, attracting thrips away from the valuable crops and facilitating easier management [52]. Recently, a chemotactic-based ethological approach was employed to manage WFT populations [53]. Such an approach used an alarm pheromone ("Push") to deter thrips from entering greenhouses and an aggregation pheromone ("Pull") for mass trapping inside the greenhouses.…”

Frankliniella occidentalis Pergande Pergande (Thysanoptera: Thripidae), broadly known as Western flower thrips (WFT), are currently one of the most critical pests worldwide in field and greenhouse crops, and their management is full of yet unsolved challenges derived from their high reproductive potential, cryptic habit, and ability to disperse. The control of this pest relies widely on chemical control, despite the propensity of the species to develop resistance. However, significant advances have been produced through biological and ethological control. Although there has recently been a remarkable amount of new information regarding the management of this pest worldwide, there is no critical analysis of recent developments and advances in the attractive control tactics for WFT, constituting the present compilation’s aim. Hence, this narrative review provides an overview of effective control strategies for managing thrips populations. By understanding the pest’s biology, implementing monitoring techniques, accurately identifying the species, and employing appropriate control measures, farmers and researchers can mitigate the WFT impact on agricultural production and promote sustainable pest management practices.

“…For example, the combined utilization of attractants and entomopathogenic fungi has resulted in great savings for both labor and biopesticide dosage costs [15]. The combination of aggregation pheromone and alarm pheromone is successful in thrips control in greenhouses [16]. Therefore, research on the interactions between semiochemicals and pests is essential in developing effective methods to control thrips populations.…”

Pheromone trapping is an interspecific, active at low concentrations, eco-friendly pest management strategy that has been widely used for population monitoring. Pheromones have only been validated for a few species in Thysanoptera and the pheromone components of Odontothrips loti Haliday are still unclear. In our study, we have identified (R)-lavandulyl (R)-2-methylbutanoate from male O. loti headspace volatiles by gas chromatography-mass spectrometry (GC-MS), which was structurally similar to the known reported aggregation pheromone of Megalurothrips sjostedti. Y-tube olfactometer assays showed that both male and female adults O. loti were significantly attracted by synthetic (R)-lavandulyl (R)-2-methylbutyrate, implicating as an aggregation pheromone. Additionally, electroantennogram responses of O. loti increased with increasing doses of synthetic (R)-lavandulyl (R)-2-methylbutyrate. This is the first report of a male-produced aggregation pheromone in O. loti, from genus Odontothrips. The discovery of aggregation pheromone of O. loti as a primary pest of alfalfa will provide the possibility of monitoring and early warning in alfalfa grass fields and is expected to be used for integrated management for O. loti.

“…Animal-derived biomaterials, such as sex and aggregation pheromones, as well as predator kairomones, have been increasingly used in pest control (Witzgall et al 2010;Yang et al 2022;Kim et al 2023;Okosun et al 2013). For example, the cuticular hydrocarbon from predator backswimmer deterred female mosquitoes from ovipositing in natural pools (Silberbush et al 2010); while chemicals from abdominal gland secretions reduced small brown planthopper populations in rice paddies (Wen and Ueno 2021).…”

Bactrocera dorsalis (Hendel) is a major global pest of fruits and vegetables. Interestingly, field studies revealed that the presence of the red imported fire ant, Solenopsis invicta Buren, reduces the visiting frequency of B. dorsalis and fruit damage. However, the underlying mechanisms remain unknown. In this study, we hypothesized that S. invicta can produce semiochemicals that non-consumptively repel B. dorsalis, thereby reducing damage to fruits caused by feeding and oviposition. We investigated how S. invicta poop, saliva, and footprints influence the behavior of B. dorsalis. Subsequently, we analyzed the chemical composition of S. invicta footprints and conducted field experiments to evaluate their efficacy as repellents against B. dorsalis. The results demonstrated that S. invicta footprints effectively repel the visiting behavior and decrease the number of eggs laid by B. dorsalis. Among the nine compounds identified, d-limonene, acetic acid, and a mixture of seven compounds showed strong repellent effects on the visiting frequency and egg-laying of B. dorsalis. Field experiments confirmed the effectiveness of S. invicta footprint compounds in controlling B. dorsalis, resulting in reduced fruit damage in mango, guava, and wax apple trees. These studies provide valuable insights into the non-consumptive effects of S. invicta footprints on B. dorsalis behavior, unraveling the chemical communication between these two invasive species, and offer new pest control methods using invasive predators when direct release is limited.
