“…At the time Hindenlang et al, (1975) started their work on the potato tuberworm moth, only Cj6-carbon chain acetates were known as pheromones for gelechiid moths. Therefore they focussed on Cl~-carbon chain acetates, but they soon had to return to the classical approach.…”

The sex pheromone of the potato tuberworm moth, Phthorimaea operculella (Zell.) has been identified as a mixture of trans‐4, cis‐7‐tridecadienyl acetate and trans‐4, cis‐1, cis‐10 tridecatrienyl acetate. The identifications have been carried out by means of electroantennography, mass, infrared and n.m.r. spectroscopy. The identifications have been confirmed by synthesis. Both compounds occur in the insects in about equal amounts. The individual compounds are attractive to male moths in pheromone traps. The triolefinic ester was found to be much more attractive than the diolefinic ester. However, mixtures of both compounds in the ranges of 4:1 tot 1:4 are much more attractive than the individual compounds or traps baited with two virgin female moths. ZUSAMMENFASSUNG SEXUALPHEROMONE DER KARTOFFELMOTTE, PHTHORIMAEA OPERCULELLA. ISOLIE‐RUNG, IDENTIFIKATION UND FREILANDBEWERTUNG Das Sexualpheromon von Phthorimaea operculella (Gelechiidae) wurde identifiziert als ein Gemisch von trans‐4, cis‐7‐Tridecadienylacetat und trans‐4, cis‐1, cis‐10‐Tridecatrienylacetat. Die beiden Identifizierungen wurden durchgeführt mit Hilfe von Elektroantennografie, Massenspektroskopie, Ultrarotspektroskopie und Kernspinnresonanzspektroskopie. Die beiden Identifizierungen wurden durch Synthese bestätigt. Die Pheromonkomponenten wurden in etwa gleiche Mengen von den Faltern isoliert. Beide Substanzen erwiesen sich sowohl in natürlicher wie in synthetischer Form als aktiv in der Elektroantennografie sowie im biologischen Test und in Sexfallen. Ein Mischungsverhältnis der beiden Komponenten von 4: 1 bis 1: 4 weist eine viel höhere Lockstoffwirkung auf als die beiden Einzelkomponenten oder als zwei lebende Weibchen. Ein Isomer des natürlichen Tridecatrienylacetat, nämlich cis‐4, trans‐7, cis‐10‐Tridecatrienyl‐acetate, war nur schwach aktiv in den verschiedenen Testen. In Sexfallen wurde die Aktivität dieses Isomers durch Zusatz von trans‐4, cis‐7‐Tridecadienylacetat nicht erhöht.

“…More effective and environmentally-friendly control tactics are needed. Pheromone traps have been used for population monitoring, mating disruption, and attract-and-kill of male moths ( Hindenlang et al 1975 , Persoons et al 1976 , Kroschel and Zegarra 2010 , Kroschel and Zegarra 2013 ). However, such practices can only be successful for insect species with sexual reproduction of which parthenogenesis development from unfertilized eggs does not occur.…”

Parthenogenesis, a natural form of asexual reproduction produced from unfertilized eggs, occurs in many insects in Hemiptera and Hymenoptera, but very rarely in Lepidoptera. The current study aimed to test the larval density dependent occurrence of parthenogenesis in potato tuber moth, Phthorimaea operculella (Zeller; Lepidoptera: Gelechiidae) under laboratory conditions. More than 10% of females out of 25 tested females that developed from the high larval density treatment at 45 larvae per tuber were capable to reproduce asexually. Both male and female offspring were produced parthenogenetically. The sexually reproductive offspring of a laboratory parthenogenetic population had a lower egg hatch rate, shorter larval stage, and shorter male life span when compared with the non-parthenogenetic population. This suggests that the sexually reproductive offspring of parthenogenetic population have a decreased overall fitness compared to the sexually reproductive offspring of non-parthenogenetic population.
