Background: Ips typographus (L.), the eight-toothed spruce bark beetle (Coleoptera: Scolytinae), has devastated European Norway spruce (Picea abies) forests in recent years. For the first time, I.

Composed of ~60 independent olfactory neuron classes, with several associated hygrosensory and thermosensory pathways, it has been subject to diverse types of experimental analyses. However, synthesizing the available data is limited by the incompleteness and inconsistent nomenclature found in the literature.

Antennal sensillar structures respond to a variety of environmental stimuli. In the present study, the antennal sensilla of all three subfamilies of the family Lygaeidae are studied for the first time. This research shows the presence of five main types of sensilla (sensilla trichodea, chaetica, campaniformia, basiconica, and coeloconica).

Insects have highly developed olfactory systems in which cytochrome P450s (CYPs) were involved as odor-degrading enzymes throughout the olfactory recognition of odor compounds by insects to avoid continuous stimulation of signaling molecules and thus damage to the olfactory nervous. To understand whether the highly expressed CYPs in the antennae play an olfactory function in worker, in this study, we find six highly expressed antennal CYPs from the transcriptome of . Multiple sequence alignment and phylogenetic analysis divided them into two families: the CYP3 family (, ) and the CYP4 family (, , , ).

The poplar moth, (Lepidoptera: Lyonetiidae), is widely distributed across Europe, Asia, and parts of Africa. It was first identified in Chile in 2015 and has since become a significant pest in the agricultural sector. Additionally, economic losses are further aggravated by the presence of pupae in nearby fruit orchards.
