Abstract
Several methyl‐branched saturated C32, C33, and C34 hydrocarbons have been identified from larvae and mandibular glands of Heliothis virescens (F.) (Lepidoptera, Noctuidae) that trigger a short‐range host‐seeking response of its parasitoid, Cardiochiles nigriceps, Viereck (Hymenoptera: Braconidae). Although the individual components elicited a response, a mixture of the most active C32, C33, and C34 hydrocarbons was significantly more active than the individual components; some mixtures were as active as the contents of the mandibular gland of the host.Zusammenfassung: ISOLIERUNG, IDENTIFIZIERUNG UND SYNTHESE DER DIE WIRTSSUCHE STIMULIERENDEN STOFFE BEI CARDIOCHILES NIGRICEPS, EINEM PARASITOID DES TABAKKNOSPENWURMSIsomere Monomethylalkane in den Larven und in der Mandibeldrüse von Heliothis virescens, die bei ihrem Parasitoid, Cardiochiles nigriceps, nach Kontakt eine wirtsuchende Wirkung besitzen, wurden identifiziert. Mischungen mehrerer, als aktiv erkannter Substanzen (z.B. 12‐Methyl C31 + 12‐Methyl C32 + 13‐Methyl C33, optimal zusammen 500 ng) wirkten stärker als die einzelnen Komponenten und konnten die Wirkung des Mandibulardrüseninhalts erreichen.Keywords
