Attractants
 
[ə'træktənts, englisch] Plural, Attraktạnti|en, Lockstoffe, chemische Verbindungen, die bereits durch winzige Mengen ihrer Dämpfe Insekten selbst aus weiten Entfernungen anlocken. In Verbindung mit Ködern und Fraßgiften gelingt es, auf diese Weise chemotaktisch orientierte Schadtiere zu bekämpfen (z. B. Borkenkäfer). Bei der biotechnischen Insektenbekämpfung werden Sexuallockstoffe (Pheromone) in Fallen eingesetzt (Fallenmethode) oder über das Biotop verbreitet und dadurch die Orientierung der Männchen nach den Weibchen unmöglich gemacht (Verwirrungsmethode).
