The highly developed sensitive olfactory system is essential for Scott (Hemiptera: Pentatomidae) adults, an widely distributed natural predatory enemy, to locate host plants. During this process, odorant-binding proteins (OBPs) are thought to have significant involvement in the olfactory recognition. However, the roles of OBPs in the olfactory perception of are not frequently reported. Here, we conducted odor exposure and transcriptome sequencing experiments using healthy and -infested tobacco plants as odor sources. The transcriptomic data revealed that the alteration in the expression of mRNA levels upon exposure to odor was sex-dependent. As the expression profiles differed significantly between male and female adults of . A total of 15 OBPs (PlewOBPs) were identified from the transcriptome. Sequence and phylogenetic analysis indicated that PlewOBPs can be classified into two subfamilies (classic OBP and plus-C OBP). The qRT-PCR results showed that the transcript abundance of 8 substantially altered following exposure to -infested tobacco plants, compared to the blank control or healthy plants. This implies that these may have an olfactory function in detecting -infested tobacco plants. This study establishes the foundation for further understanding of the olfactory recognition mechanism of . and helps discover novel targets for functional characterization in future research.

Background: Piercing-sucking insects secrete diverse repertoires of effectors into their hosts to weaken host defenses and promote infestation. The Asian citrus psyllid, Diaphorina citri Kuwayama, is the most destructive insect pest in citrus orchards because of its role as a vector for the huanglongbing pathogen, Candidatus Liberibacter asiaticus (CLas). However, specific effector proteins and their functions in D.

Parasitic plants represent a significant challenge in global agriculture, with Broomrape (/ spp.) being a notable example of a holoparasitic species that targets the roots of host plants. This study employed comparative transcriptomics to investigate the mechanisms underlying the parasitism of on melon, focusing on both resistant and susceptible interactions.
