Abstract Drosophila suzukii ( D. ), a pervasive pest originating from Southeast Asia, presents substantial risk to global agriculture. The ability of the female flies lay eggs within fruits varying maturity stages, combined with accelerated offspring development warmer climates, results in rapid population growth. This poses significant challenges for fruit production and viticulture, exacerbated by increasing prevalence pesticide resistance. We propose solution this growing issue using an attract-and-kill approach making use upcycled organic waste materials made orange peels. Specifically, we have tested innovative salty peel product (OPP) choice experiment, which OPP hydrogel (control) were available Petri dishes situated beneath red wine grapes. number dead both counted each day fly maggots inside berries extracted after four days. Since covered lid, only selected on basis olfactory cues. Our showed higher captured containing compared those control. Furthermore, notable reduction was observed grapes located above closer Dilution followed lower count flies. In additional experiments, concentration NaCl found be positively correlated suggests important lethal effect caused high salt concentrations. final also commercially-available attractant called Drosalure™, resulted slightly attractiveness . These findings suggest that holds potential as cost-efficient eco-friendly biocide material. offered traps equipped small entry holes is safe bees may replace other less control measures vineyards.

ABSTRACT The detection of internal chemicals by interoceptive chemosensory pathways is critical for regulating metabolism and physiology. molecular identities interoceptors, the functional consequences chemosensation specific neurons remain to be fully described. C. elegans pharyngeal neuronal network anatomically functionally homologous mammalian enteric nervous system. Here, we show that I3 neuron responds cations via an I3-specific variant ionotropic receptor (IR) regulate salt stress tolerance. GLR-9 IR, located at gut lumen-exposed sensory end I3, necessary sufficient sensation, establishing a function IRs beyond insects. Salt protects specifically against high stress, as glr-9 mutants reduced tolerance hypertonic but not sugar solutions, with or without prior acclimation. While cholinergic signaling from promotes acute peptidergic during acclimation essential resistance subsequent challenge. Transcriptomic analyses regulates in part expression osmotic response genes distal tissues. Our results describe mechanisms which mediated defined physiological homeostasis abiotic stress.

Chemosensation and mechanosensation are vital to insects’ survival behavior, shaping critical physiological processes such as feeding, metabolism, mating, reproduction. During insects rely on diverse chemosensory mechanosensory receptors distinguish between nutritious harmful substances, enabling them select suitable food sources while avoiding toxins. These distributed across various body parts, allowing detect environmental cues about quality adjust their behaviors accordingly. A deeper understanding of insect sensory physiology, especially during not only enhances our knowledge biology but also offers significant opportunities for practical applications. This review highlights recent advancements in research feeding-related receptors, covering a wide range species, from the model organism Drosophila melanogaster agricultural human pests. Additionally, this examines potential targeting precision pest control. Disrupting feeding reproduction emerges promising strategy management. By interfering with these essential behaviors, we can effectively control populations minimizing impacts promoting ecological balance.
