“…30 The open reading frame encoding BdorOR49b was cloned into the pUAST-BdorOR vector and extracted and purified by recombinant plasmid (Qiagen Midi Kit). The plasmid was injected into undifferentiated fertilized eggs of D. melanogaster with y [1] M{vas-int.Dm}ZH-2Aw [ * ] P-{CaryP}attP2 as the background strain. Independent homozygous UAS-BdorOR49b lines were generated by Fungene Biotech (Qidong, China).…”

The ability to recognize a host plant is crucial for insects to meet their nutritional needs and locate suitable sites for laying eggs. Bactrocera dorsalis is a highly destructive pest in fruit crops. Benzothiazole has been found to induce oviposition behavior in the gravid B. dorsalis. However, the ecological roles and the olfactory receptor responsible for benzothiazole are not yet fully understood. In this study, we found that adults were attracted to benzothiazole, which was an effective oviposition stimulant. In vitro experiments showed that BdorOR49b was narrowly tuned to benzothiazole. The electroantennogram results showed that knocking out BdorOR49b significantly reduced the antennal electrophysiological response to benzothiazole. Compared with wild-type flies, the attractiveness of benzothiazole to BdorOR49b knockout adult was significantly attenuated, and mutant females exhibited a severe decrease in oviposition behavior. Altogether, our work provides valuable insights into chemical communications and potential strategies for the control of this pest.

“…Animals detect, track and locate a variety of resources in rapidly changing environmental conditions. Chemical cues are amongst the most predominant ecological drivers of animal behavior and exert major influences on resource acquisition [1,2]. Perhaps nowhere in animal lineages is this dependency on olfactory information more evident than in insects, where accurate and timely chemical detection is necessary for life history traits such as foraging, toxin and predator avoidance, egg deposition, and mate selection.…”

Diptera is a megadiverse group of flies with sophisticated chemical detection systems, which exploits an incredible variety of ecological niches. Among the vast array of odorants in natural environments, indoles stand out as playing crucial roles in mediating fly behavior. In mosquitoes, indolic compounds are detected by an ancient class of conserved indolergic Odorant Receptors (indolORs). In this study, we have identified a set of 92 putative indolOR genes encoded in the genomes of Nematoceran and Brachyceran flies, resolved their phylogenetic relationships, and defined conserved elements in their gene structures. Further, we have quantified indolOR transcript abundance in the antennae of the housefly, Musca domestica, and have characterized MdomOR30a as a skatole receptor using a heterologous expression system. The presence of indolORs in species operating in different ecological contexts suggests that indoles act as pleiotropic signals for resource exploitation at multiple developmental stages. Further characterization of indolORs will impact our understanding of insect chemical ecology and will provide targets for the development of novel odor-based tools that can be integrated into existing vector surveillance and control programs.
