Partial characterization of stress-induced carboxylesterase from adults of Stegobium paniceum and Lasioderma serricorne (Coleoptera: Anobiidae) subjected to CO₂-enriched atmosphere
Journal of Pest Science 82 (1), 7-11
Abstract: The kinetics effects of carbon dioxide enriched atmosphere on carboxylesterase (CarE) activity from Stegobium paniceum and Lasioderma serricorne were comparatively investigated here. The results showed that L. serricorne had significantly greater specific activity of CarE than S. paniceum [0.399 vs. 0.358 mmol (min mg)^-1]. Moreover, CarE of L. serricorne expressed a higher affinity (i.e. lower K _m value) to the substrate alpha-naphthyl acetate than S. paniceum (0.1 vs. 0.8 mM). The in vitro kinetics of CarE showed that there were no significant effects of controlled atmosphere on the affinity of carboxylexterase to alpha-naphthyl acetate for both pests besides increased of V _max values. Such result draws attention to the higher tolerance of L. serricorne to CO₂-enriched atmosphere and the necessary care required for managing this species with such a control tactic. The information also suggests a potential effect of esterases in mitigating the toxic effect of controlled atmosphere in insect pest species.
