Abstract

<abstract abstract-type="main" xml:lang="en" id="eea12053-abs-0001"> <title>Abstract</title> <p>Anecdotal evidence suggests that cockroaches respond to electrical appliances or outlets. Our objectives were to determine the effect of field‐inducing sources and field attributes on attraction of German cockroaches, <italic>Blattella germanica</italic> (L.) (Blattodea: Blattellidae), and to test those parameters found effective for attraction of <italic>B. germanica</italic> for attraction of other groups of insects. In two‐choice, large‐arena experiments, significantly more female, but not nymphal, <italic>B. germanica</italic> settled in or near electrified coils with static or fluctuating electromagnetic fields produced by low‐level direct current (DC) or alternating current (AC) sources than in control coils without current. Electromagnetic fields with the magnetic, but not the electric, component of the field nulled still attracted <italic>B. germanica</italic>, suggesting that the electric component of the field may contribute to the attraction or arrestment response of <italic>B. germanica</italic>. DC‐powered coils with static electromagnetic fields also attracted/arrested brown‐banded cockroaches, <italic>Supella longipalpa</italic> (Fabricius) (Blattodea: Blattellidae), common silverfish, <italic>Lepisma saccharina</italic> (L.), firebrats, <italic>Thermobia domestica</italic> (Packard) (both Thysanura: Lepismatidae), and European earwigs, <italic>Forficula auricularia</italic> (L.) (Dermaptera: Forficulidae), but they repelled American cockroaches, <italic>Periplaneta americana</italic> (L.) (Blattodea: Blattidae). If proven in field experiments, electrified coils as trap baits may offer non‐toxic alternatives to pesticides for selective insect control in urban environments.</p> </abstract>
