Booklice are tiny insect pests commonly found in an indoor environment and characterized by extremely high proliferation ability. Booklouse contamination in stored foods causes serious food loss; therefore, they are recognized as so-called stored-food pests. Furthermore, since booklice in house dust have been reported to be a potent allergen, it should be also considered that the accidental ingestion of booklice possibly causes allergic symptom. Therefore, safe extermination of booklice would contribute to the solution of both food-loss and allergic concerns. Organophosphates (OPs) are compounds generally used as harmless insecticides; nonetheless, the cases of OP poisoning are sometimes reported worldwide. Therefore, considering usage for stored food products, OP doses should be low as far as possible. It is known that carboxylesterase-mediated inactivation of OPs decreases the efficacy of OPs, suggesting that an inhibitor of carboxylesterase could be a synergist to reduce the dose of OP. Herein, I report the molecular cloning and characterization of a novel carboxylesterase highly expressed in a representative species of indoor booklice, Liposcelis bostrychophila.
