Abstract
To investigate the feasibility of using coatings of residual insecticides as a means of preventing the casual introduction of insect pests in overseas aircraft, 5 insect species — Aedes notoscriptus (Skuse), Aphodius tasmaniae Hope, Cydia pomonella (L.), Musca domestica L., and Periplaneta americana (L.) — were confined on permethrin treated surfaces of various materials commonly used in aircraft linings and furnishings. Permethrin 40/60 and permethrin 25/75 applied at 0.1-0.2 g a.i. per m2 to impervious surfaces or at 0.5-1.0 g a.i. per m2 to cloth or carpet proved to be capable of killing all the test species after a brief period of confinement on the treated surface, and remained effective for at least 14 weeks. Permethrin coatings on some painted surfaces, however, lost their effectiveness in a few days.
