Varroa mites (Varroa destructor) continue to pose a serious threat to honey bee (Apis mellifera spp.) health, exhibiting significant resistance development to synthetic acaricides. This study investigated the efficacy of thyme (Origanum onites L.) essential oil (TEOV) as botanical alternative, focusing on mite survival across different feeding contexts and the underlying molecular responses. Adult mites were exposed to three TEOV doses (0.1, 1, and 10 ppm), across different feeding contexts (GA;larvae, GB;fat body, and GC;live honey bee). Mortality exhibited dose and time dependency, particularly at 24 h post-exposure to TEOV. The most responsive host tissue was found to be the mites feeding on larvae and fat body tissue. Interestingly, the susceptibility of the mites was found to be influenced by the context of feeding, which suggests that nutrition affects the susceptibility of TEOV. At the molecular level, TEOV elicited delayed but dose-dependent transcriptional responses: pheromone receptor transcription factor-like (PRTF-like) was strongly upregulated at higher doses after 24h, consistent with activation of stress- or detoxification pathways, additionally Ionotropic glutamate receptors (IGRs)- Ionotropic Receptor 25a-like (IR25a-like) exhibited a general, significant elevation in response to TEOV exposure, suggesting an effort to activate an adaptive chemosensory response. In contrast, the expression of GABA-activated RDL (Dieldrine Resistance) receptor (GABA-RDL) was not generally affected at any dose or time of observation. The result reveals that the neurotoxic action of TEOV is not through transcription-regulated pathway via this receptor. No activity of the mite genes was detected in the control group indicating that any gene activity changes are attributable to treatment with thyme. The selectivity ratio (SR) was calculated as 17.0. The materials have shown their mortality rates, gene expression and physiology by two mechanisms: a fast action as neurotoxicants and long-term stress for TEOV. All results demonstrate its potential as a plant-derived acaricide.
