Gene silencing of Si Orco and Si OBP5 through dsRNA injection (RNA interference) reduced gene transcription at 72 hours post-treatment and disrupted detection of 2,4,6-trimethylpyridine according to electroantennography assays ( Si OBP1 was highly expressed in the antennae of worker ants, and its protein was identified in the antennae proteome of males and workers ( Si OBP1 protein was predicted through an in silico approach and confirmed through experimental methods ( Si OBP1protein exhibited the highest affinity for -caryophyllene (0.1 g/L) and the lowest affinity for 2,5-dimethylhexane (0.1 g/L) ( Si OBP1 gene was silenced via RNAi ( On the other hand, Si OBP2 and Si OBP14 modulate workers foraging behavior ( Si OBP2 was expressed in the sensilla basiconica of the RIFA workers antennae and was involved in detecting the alarm pheromone 2,4,6-trimethylpyridine, while Si OBP14 was expressed in the antennae of workers and males ( Si OBP2 gene via RNAi disrupted OBP2 protein binding to the bait sausage odorants 3-mercapto-2-butanone and furfuryl mercaptan in accordance with electroantennography assays ( Si OBP14 gene silencing (RNAi) led to a shift from attraction to repellency towards 2-methyltetrahydrofuran-3-one, 2-methyl-3-furanthiol, 4,5-dimethylthiazole, and 2-methyl-3-methyl(thio)furan released by bait sausages for RIFA workers ( Si OBP2 and Si OBP14 gene repression significantly impaired the bait-sausage-searching efficiency of RIFA workers ( The general protein 9 (Gp-9) or Si OBP3 determines the social structure of RIFA colonies
