This research aimed to determine the effect of exposing <em>T. castaneum</em> to abamectin on subsequent orientation to traps containing its aggregation pheromone 4,8-dimethydecanal and a kairomone.

The highest attraction (53%) to pheromone + kairomone vial observed at 2.5 ppm which was greater than adults not exposed to abamectin. Overall, trapping decreased with increasing concentrations of abamectin beyond 2.5 ppm. Under simulated warehouse conditions, the highest trapping (29%) occurred in insects exposed to 1 ppm abamectin and was not significantly different from 0 ppm (no pheromone) and 2.5 ppm. The lowest trapping (8%) occurred at 15 ppm which was not significantly different than 20 ppm.

Additionally, we employ transcriptomic analysis to elucidate the physiological and metabolic mechanisms that <em>C. malaccensis</em> engages under stress conditions. Under the same fumigation duration, the mortality rates of both adult and egg increased with higher concentrations of sulfuryl fluoride. The LC₅₀ for adult mites after 48 h of fumigation was approximately 1.58 g/m³, while the LC₅₀ for egg was around 26.48 g/m³. When the fumigation time for egg was extended to 60 h, the mortality rate at a concentration of 25 g/m³ increased by approximately 1.4 times; after 72 h, the mortality rate at 15 g/m³ rose by 3.6 times. Egg exhibited greater tolerance to sulfuryl fluoride fumigation compared to adult. Neither adult nor egg could survive in high-concentration, long-duration fumigation environments. <em>C. malaccensis</em> can be released after the fumigation has dissipated (with sulfuryl fluoride concentrations not exceeding 2.3 g/m³), allowing it to effectively establish populations in real storage facilities for long-term control.
